Siddha science is the oldest one, generated from Dravidian culture. Siddha medicine grew out

of empirical observations that were handed from generations to generations. In Siddha system

there is still lot of incognito fields which is unexplored to the present day scenario. People

rely entirely on native medicine, before the invention of modern medicine practices. From the

social occurrence, an individual encounters relatively unchanged disease conditions as of

now. In siddha system, the physicians skillfully managed every condition with specialized

procedures. There exist Kirigai maruthuvam, kayakarpa procedures and techniques are of

great current value in preventive and curative aspects of geriatric health care. The context of

Kayakarpa therapy and its attanga yogam and karpa avizhtham components are largely

unexplored part of ancient wisdom. There is a great need to make aware the professionals as

well as the public about the use of Siddha Kayakarpa remedies given in Siddha texts. There is

also a need to carry out applicable research plans in the Siddha field to develop an evidence-

based approach to treat senile individuals with neuro psychiatric issues. This article reviews

the pharmacological and non-pharmacological interventions in Siddha system for the

management of senile dementia and throws some scientific light on the age-old practices to

bring that into current-day clinical practice. The modern approach has some downsides, in

which the Siddha system can fill the gaps in natural way, especially in the cases of dementia

in elderly.

INTRODUCTION

Dementia is a descriptive term for a collection of symptoms that affect the brain. People with these symptoms may

experience cognitive difficulties, personality changes, and behavioral problems. While these problems most often affect the elderly,

they are not a normal part of aging. Globally, 44.4 million people were estimated with dementia. By 2030, this estimate will rise to

75.6 million, and 135.5 million by 2050. Developing countries has Considerable growth, which implies that at present there is 62%

dementia people will rise to 71% by 2050. There is reckless upsurge of aged people in China, India, and their south Asian and western

Pacific neighbours [1]

.In 2010, 35.6 million people were assessed to be living with dementia. Each year, the incidence is 7.7 million

cases, which indicate that for every four second there is a new dementia patient arises. The accelerating rates of dementia are cause for

immediate action, especially in low- and middle-income countries where resources are few [2]

.

Dementia remains a largely hidden problem in India, especially in those parts of India where poverty and illiteracy levels are

high. India was home to more than 75 million people older than sixty years in 2001. This age group, which was 7.5% of the

population, is expected to grow dramatically in the coming decades [3]

. The demographic profile depicts that in the years 2000–2050,

the overall population in India will grow by 55%whereas the aged population of 60 years and above will increase by 326 % and those

in the age group of 80+ by 700 % [4]

. This has resulted in an increased proportion of older people in the total population, termed as the

―graying of population‖ [5]

. The burden of mental disorders‘ morbidities is increasing in the Indian elderly due to ageing of the brain,

problems associated with physical health, cerebral pathology and socio-economic factors such as breakdown of the family support

systems, social isolation and decrease in economic independence [6]

.

Dementia has wider impact of the overwhelming illness process on the affected people, their families, the society and the

nation at large. The evidence base for management of dementia is lacking. The pharmacological and non-pharmacological treatment

approaches are being followed for centuries in Siddha practice. There is also a need to carry out applicable research plans on the age-

old practices to bring that into current-day clinical practice and to develop an evidence-based approach to treat senile individuals with

neuro psychiatric issues. The modern approach has some downsides, in which the Siddha system can fill the gaps in natural way,

especially in the cases of dementia in elderly. An in depth view, to the extents of kayakarpam will lead to break-through in combating

various incurable diseases such as dementia. The aim of this review is to deal about the siddha treatment approaches for the

prevention and management of neuro psychiatry illnesses of elderly, especially senile dementia.

Neurodegenerative diseases Neurodegenerative diseases represent a large group of neurological disorders with heterogeneous clinical and pathological

expressions affecting specific subsets of neurons in specific functional anatomical systems; they arise for unknown reasons and

progress in a relentless manner. Neurodegenerative disorders are a major cause or mortality and disability. Alzheimer‘s disease is the

major cause for dementia, which accounts for 50 to 70%. The second most common type of dementia is vascular dementia, which is

caused by deficient blood flow to the brain. Multi‑infarct dementia can arise when sequence of small strokes affect tiny arteries. Many

individuals with Parkinson‘s have dementia at the advanced stage of the disease. Dementia with lewy bodies starts with wide

disparities in attention and alertness. Individuals affected by this illness frequently experience visual hallucinations as well as muscle

rigidity and tremors like those associated with Parkinson‘s disease. The automobile accident or other trauma causes brain injury,

which cause symptoms of dementia such as behavioral changes, memory loss, and other cognitive difficulties. Huntington‘s disease is

an inherited, progressive disorder that causes irregular movements of the upper and lower limbs, facial muscle palsy, personality

changes, and weakening of thinking ability.

Creutzfeldt‑Jakob disease (CJD) is a rare, rapidly fatal disorder that retards memory and coordination causing behavioral

changes. Among hundreds of different neurodegenerative disorders, attention has been given to Alzheimer‘s disease (AD),

Parkinson‘s disease (PD), Huntington disease (HD) and amyotrophic lateral sclerosis (ALS). The number of neurodegenerative

diseases is currently estimated to a few hundred and among these; many appear to overlap with one another clinically and

pathologically leads to confusion in classifying the diseases [7]

.

Siddha medicine Siddha science is the oldest one, generated from Dravidian culture. It came to South India when the Tamil people, who may

have been the original inhabitants of the Indus valley, migrated southward [8]

. It is thought to have developed during the Indus

civilization, which flourished between 2500 and 1700 BCE [9]

. Siddha medicine grew out of empirical observations that were handed

from generations to generations. Siddhars, who are the sect of Tamil sages, derived the medicinal ideas and practices of Siddha

medicine. Siddhars, the fore runners of native medical science of South India, have attained Siddhis by virtue of perception and super

natural powers. Ominously, one of the descriptions of Siddha medicine is conquest of death: ―that safeguards one against mortality‖.

Thirumoolar Siddhar‘s Thirumantiram literature, a classic text on the basic philosophy of Siddha medicine authorizes this description.

One of the notable characteristics of Siddha treatment relates to an intricate technique known as Kaya Karpa method that is used for

rejuvenation and the presumed immortalisation of the human body [10]

. Siddha medical science most distinctly emphasizes the practice

of Kayakarpam to rejuvenate the body and mind that eventually slows down biological ageing.

Psychiatry in Siddha medicine Kirigai Maruthuvam, the Neuro-psychiatry in Siddha system of medicine is propounded by several siddhars of whom the

most renowned are Agasthiyar, Yugimunivar and Theraiyar. Their descriptions are phenomenological. In Siddha system, the

physiology of human body is dealt in 96 Thatthuvangal (Philosophy)[11]

. Of the 96 thatthuvam, Maṉam (Mind), butthi (Wisdom,

Decision making), Chittham (Determination), Muṉaippu (Accomplishment) are responsible for mental well-being. Muṉaippu is the

innate character of Maṉam. Manam (Mind) is responsible for thinking, reasoning, planning and Self-realization. The Mind and

physique are inseparable and inter dependable. Maṉam is both receptive and executive. In-appropriate Food, seasonal variations,

somatic diseases, and drug abuse are some of the factors that influence the mind. This stimulates the three humours vali, Azhal and

iyam, especially deranges Vaḷi or Azhal or often the predominance of Azhal humour over the other two, thereby manifest Maṉa

Nōikaḷ (Mental diseases). Agasthiya maanidar kirigai nool and Yugi chinthamani-800 are noteworthy psychiatric literatures in siddha

system. They classified the clinical variety of mental illness, based on symptomatology. It absolutely correlates with modern neuro

psychiatric illnesses like schizophrenia, mania, depression, convulsive disorders, neurotic illnesses, drug dependence, toxic psychosis

etc.

In Siddha system,

Kalikkam (application of eye drops),

Anjanam(eye lid application),

Nasiam(ingestion of medicated oil into the nostrils),

Aakkiraanam (inhalation of dry herbal powders through nose) ,

Pugai (imbibing of herbal smoke),

Kudori marutthuvam (rubing medicines in the incised skin parts),

Thuvaalai(application of medicated oil/herbal paste/herbal mixture),

Ennai muzhukku( medicated oil bath) are in practice to treat Kirigai noigal [12]

.

Kaya karpam

Among the fields of Siddha medicines, Karpa medicines for rejuvenation and prevention of diseases and Yoga practice for

physical and mental well-being, said to be the hallmark of this system [11]

. The Tamil word ‗kaya‘ means body and ‗karpa‘ means

stone. Therefore, ‗kayakarpam‘ means sturdy as a rock and ageless physical body. While consuming karpa medicines, it naturally

prevents the body from diseases and deterioration of physical stature. Kayakarpam usage provides both mental and physical wellness

to the individual. Kaya karpa therapy encompasses pharmacological and non-pharmacological regimens. The oral therapies (Karpa

avizhtham) are from herbal, Mineral and animal sources which includes dietary and medicinal habits. The physico-intellectual method

(Karpa yogam) is known as Attanga yogam practices, which are non-pharmacological methods described in Siddha literatures [12]

.

Unlike the disease modifying activity, these Kayakarpa drugs enhance the immunity and counteracting the aging process. The

supremacy of Siddha medicine in the context of Geriatric care through Kaya Karpam therapy is unique because of its ability to

promote longevity and influence all aspects of health in a positive way [13]

. Describing the effects of Kaya Karpam, the classical texts

of Siddha say that from Kaya Karpam, one can attain longevity, improved harmony and intelligence, freedom from disorder, youthful

vigor, complexion and voice, optimum strength of physique and senses, command over language, respectability and brilliance [14]

.

Siddhars had firm faith in the immortal physical body and the soul (Seevaathma) is being in tune with the spiritual divinity

(Paramaathma) which helps to realize and reach the omnipotent.

Karpa Avizhtham (Kayakarpa Medicines)

Karpa avizhtham or oral medicines include herbal, mineral and animal product preparations. Kayakarpa recipe is to build a

strong body. Karpa avizhtham are of two types, by preparing it daily or make it as some types of internal and external medicines such

as powder (churanam), decoction (kudineer) forms, poochu (external application) etc. Herbal Karpa avizhtham are mentioned in

various Siddha literatures such as Theraiyyar yamaga venba, Bohar karpam 300, Bohar 7000, Thiruvalluvar karpam 300, Pulathiar

karpam 300 etc. Mineral Karpa medicines are given in Agatthiyar chendooram300, Bohar 7000& 700 etc. The herbal kayakarpam,

emphasized by Thiruvalluva nayanar is that in the morning intake of fresh ginger after removing the outer skin, mixed with honey, at

noon dry ginger powder, and at evening Kadukkai (Terminalia chebula) powder mixed with water would give disease free life to a

person. [12]

. There are prepared forms of medicine, which cures diseases and act as rejuvenators. Some of which are, Aya sambeera

karpam, an iron based preparation is made from fermentation of iron soaked in lemon, Ayabringaraja Karpam is made from iron

processed in Eclipta Alba plant juice and limejuice and Poorna Chandrodaya chenthuram made up of gold, mercury, and sulphur.

Fresh and boiled cow‘s milk, cochineal insect, which are mostly seen in rainy season are the animal originated kaya karpa medicines

which are denoted in the Pathaartha guna sinthaamani literature. Karpa drugs have rejuvenating powers and are believed to retard the

aging process. Of the mercurial drugs, according to Bhogar siddhar, mercuric sulphide with gold and borax would be good for

rejuvenation and he has described a method for its preparation [11]

Kattu, Kalangu, Chatthu, Guru kuligai, Amuri and Muppu are

highly acclaimed preparations in Tamil Siddha tradition. With their great insight and deep knowledge in chemistry and metallurgy,

Siddhars evaluated a number of metal and mineral preparations, which even today challenge the incurable diseases [14]

Karpa Yogam

In Siddha system, Yogam begins with the basic attainment of purity in mind and action. It is the stepping-stone to the

successive next stages of Attaanga yogam without any incompetency. In India, Yoga sutras (Sage Patanjali‘s dictums of yoga, second

century BC), advocate controlled breathing, deliberation of mind, mastery over senses, and intense meditation techniques, moreover it

includes certain postures or exercises for psychosomatic harmony [10]

. Even before the existence of Sage Patanjali, in Tamil tradition

there was the presence of yogic practices. The archeological evidences of stone sculptures found in Mohenjo-Daro civilization

symbolizes meditative posture, ensures that the people practiced yogam. There is number of aadhanam postures that are given in

Tholkappiam, an oldest literature of Tamil language authorizes the vintage of Siddha System and yogic practices. Tholkappiam, which

has been written before 7th

Century AD, denotes eight types of Yogic practices in its Puram 75.6th

verse [15]

. Subsequently,

Thirumoolar in his works has denoted many yogic procedures, given away the tactics to attain death-less life and to halt re-birth.

Thirumoolar's writing is the basis for Attanga Yogam" (Eight-Limbed Yoga). This eight-limbed concept is derived from the

Thirumanthiram book, and is a core characteristic of every Rasayoga variation taught practically today. The Eight Limbs are:

Iyamam (Pureness of Mind)

Niyamam (Good conduct)

Aadhanam (Postures)

Praanayaamam (Breathing exercises)

Pratyaakaaram (Abstraction)

Dhaaranai (Concentration)

Dhyaanam (Meditation)

Samaadhi (Liberation)

Iyamam is said to be that having and involving good thoughts. Indulging in immoral thoughts like jealous, selfishness, anger

could eventually leads into dejected mental status that causes stress in routine life, in long run it will leads into psychiatric

illnesses.

Niyamam is to perform virtuous deeds to all living being around us, not to harm by either speech and/or act. Right diet habits,

self-cleanliness also comes under, Niyamam. One should avoid cigarette smoking and alcohol drinking etc. These habits are

with no doubt will leads to many social humiliations.

Aadhanam is a vast collection of physical postures during sitting, standing or lying on the floor, along with specific breathing

patterns.

Among the eight steps, Praanayaama method is a non-pharmaco therapeutic method in Siddha system dealt with the control

of breath. Human breath is nothing but a physical manifestation of praanan. As oxygen is taken up by the circulatory system,

so is praana taken up by the nervous system and is spent as nerve force in the act of thinking, desiring etc., Regulation of

breath enables one to absorb a greater supply of praana to be stored up in the brain and the nerve centers to be used whenever

necessary. According to the Siddhar Yugimuni, 21,600 respirations a day is the secret of remaining ever young [16].

Pratyaakaaram is the method of withdrawal of sense organs from the external objects.

Dhaaranai is fixing the attention on a single object.

Dhyaanam is intense contemplation of the nature of the object of meditation. Meditation on the elements, beginning with the

―random‖ and ending with the ―inner consciousness,‖ enable one to gain mastery over the perception.

Samaadhi is to merging consciousness with the object of meditation [12]

.

Oxidative stress and Mechanism of action of Kayakarpa medicines The brain is exposed throughout life to oxidative Stress, and certain diseases of the brain and nervous system are thought to

involve free radical processes and oxidative damage, either as a major cause or because of disease progression. There is evidence of

usefulness of herbal kayakarpam from sangam period, once the great king Athiayaman gave an eternal nellikkani (Indian gooseberry)

fruit to Avvaiyar, quoting that this is a special and potent fruit, whoever eats they can live a long healthy life. Athiyaman wanted

Avvaiyar to eat the eternal fruit because she was the right person who could serve the Tamil community. If she could live forever, so

would the Tamil heritage and language. Therefore, the knowledge of anti-ageing properties of herbal harvests was deep-rooted in

Tamil heritage [17]

.

Free radical theory

The human body cells mount up free radical harm throughout the life, so we turn old. An incomplete atom or a molecule

having a unpaired electron in the external orbit is called a free radical. The unpaired electron snips nearer cell‘s electron to couple,

which is the starting point of cell damage. The free radical consecutively creates additional free radicals and a chemical chain response

of radical production takes place [18]

. The free radicals produced in such reactions frequently laid off by eliminating an electron from a

molecule, which converts it or cannot function without it. It leads to pro oxidative shift in cellular balance which has been associated

in the cause of many diseases like diabetes, ischemic or reperfusion injuries, rheumatoid arthritis, cancer, hypertension,

atherosclerosis, neurodegenerative diseases such as Parkinson's disease and Alzheimer's dementias, and even the process of aging.

However, nature has evolved elegant regulatory mechanisms for countering this free radical damage. These primarily involve

antioxidant reducing agents that can slow or stop oxidation reaction. Some antioxidants are part of the body's natural regulating

machinery while other dietary antioxidants are derived from diet source [19]

. These antioxidant molecules donate an electron, which

neutralize the radical and stops the chemical chain reaction to reduce and prevent oxidative cell damage. The antioxidant chemicals

are abundantly present in vegetables and fruits, which forms the basis for its rejuvenating action [18]

. Kaya Karpa is that form of

treatment, which restores the aged and debilitated body to its pristine youth and vigor, re-establishes the full potentialities of the senses

and gives good health. Kaya Karpam adds new life to years and new years to life. Kaya Karpam restores Vali, Azhal and Iyam to

natural balance, brings the Saptadhatus functions to the state of equilibrium and cures many diseases.

Nootropic drugs The nootropics or Cognitive enhancers that improve creativity, recall, alertness, mental focus, cognition by protecting and

fortifying the brain cells. These substances delay or even reverse brain aging and even make young brains work better. Various

mechanisms by which the drugs acting on brain are by increasing brain circulation, supplying precursors to neurotransmitters, enhance

the neuronal function, preventing oxidative damage and providing energy to the brain. Antioxidants help to preserve the extensive

psychological capabilities, make the brain younger and defend it from oxidative loss [20]

. Kaya karpa medicines and attanga yoga

intellectual exercises can act as cognitive enhancers, which has the positive influence on body‘s natural constitution that may help to

reduce the symptoms of senile dementia and if followed regularly would prevent these disorders in elderly and improves their quality

of life.

Natural antioxidants Antioxidants are substances that help us defend our bodies against those dangerous mutants of nature called free radicals. The

two important enzymatic antioxidants are Superoxide Dismutase (SOD) and glutathione peroxidase. There are two types of SOD--one

is inside the mitochondria, the other outside, but within the cell. The one inside the mitochondria has manganese as its component, and

the one outside has zinc and copper in its structure. A small deficiency in any of these elements may greatly affect the SOD activity in

our body. These chelated minerals are generally better absorbed than the non-chelated minerals. The minerals (zinc, copper and

manganese) found in these products will aid the body to manufacture its own SOD dependably.

The other antioxidant enzyme, glutathione peroxidase has the mineral selenium, as one of its major components help to

deactivate the harmful effects of heavy metals such as cadmium, mercury, lead and aluminum and saves the cells from oxidation. Both

white and red blood cells depend on this enzyme for their proper functioning.

The third important enzyme catalase is activated by iron. Its function is primarily to neutralize the hydrogen peroxides.

Young individuals naturally produce catalase, but it drops down with age increases. Several investigations provide significant

association of catalase levels with healthy and longer life. To slow down aging, for curing pain and modulating inflammation the

catalase could be supplemented to neutralize free radicals for promoting longevity [21]

. The current evidences suggest that reduced

levels of catalase have influence in the graying process of human hair. The body naturally produces hydrogen peroxide and catalase

breaks it down. If catalase levels decline, hydrogen peroxide cannot be broken down as well. This allows the hydrogen peroxide to

bleach the hair from the inside out and preventing the melanin that produces color from synthesizing pigments [22]

. Evidence indicates

that phytochemicals having antioxidant properties reduce the symptoms of Neurodegeneration. In Siddha, Thirumoolar dictates three

types of muppu, which helps in rejuvenation of human body. Among the three, Yoga muppu is said to be the bodily production of

natural anti-oxidants, which yields disease free, glowing body. These muppu can be secreted by adoring yogic way of life [12]

. So, the

muppu, a natural anti-oxidant, if secrets in the body can prevent graying of hair, wrinkling of skin, senility and death due to aging.

Dietary karpam (General rejuvenators) Plants are potent biochemical factories and have been components of phyto medicine since times immemorial; Pothu karpam

(general rejuvenator) is being administered as regular diet. The glucose level in the brain is being increased by food substances and

supplements which has the impact on learning and memory, attentiveness and execution. The inadequacy of dietary intake leads to a

decline in the efficiencies of the brain [23]

. Depression is associated with poor nutrition, with severely compromised cognition and

functioning resulting from malnutrition. Adjusting both diet and nutrition may help some people with mental illnesses manage their

symptoms and promote recovery [24]

.

Theraiyar Siddhar assures that daily intake of Zingiber officinale (Inji then) rhizome after removing its outer skin, sliced and

soaked with honey will prevents senility, promotes good eyesight and strengthens the body. Zingiber Officinale (Zingiberaceae)

rhizomes shown potent memory enhancing action in scopolamine induced amnesia model study by significantly increasing whole

brain acetyl cholinesterase inhibition. The cognitive enhancer and neuro protective effect of ginger is due to its antioxidant activity,

which is reported [25]

. So, the nootropic action of ginger is accomplished because of the acetyl cholinesterase inhibitory action, anti-

inflammatory, antioxidant and neuro-protective property [26, 27]

.

Oryza sativa (paddy rice) flour mixed with cow‘s ghee (Nell ma nei) can be taken daily. A complete internal rejuvenation

takes place when rice protein is metabolized into health-building amino acids. These amino acids build resilient muscle that comes

back to its original form after stretching and bending, healthy skin and hair and clearer eyesight and nourish the heart and lungs,

tendons and ligaments, brain, nervous system and glandular network. Brown rice is said to contain high levels of neurotransmitter

nutrients that can prevent Alzheimer‘s disease to a considerable extent [28]

.

Alternenthera sessilis (Ponnanganni) can be cooked with ghee, pepper and salt make it as curry and taken with daily food

result in good looks. The aqueous and ethanolic extracts of aerial parts of Alternanthera sessilis at three different doses reduced

Transfer latency and significantly reversed scopolamine-induced amnesia, suggesting an underlying cholinergic mechanism [29]

Azardiracta indica (Vembu) tender leaves are ground and added with Tachyspermum ammi (omam) and salt .This powder is

specially started on rohini nakshathra for 40 days. It that the Pre-treatment with A. indica in ischemia-reperfusion injury of brain has

been demonstrated as protective effect on brain cells due to its antioxidant property and it can inverse cognitive deficits induced by

chronic hypo perfusion of rat brain on bilateral carotid artery ligation technique[30].

The recent scientific reports also suggest that neem

possess antioxidant and cognition-enhancing actions [31]

.

Intake of Aloe barbedenses (Katrazhai) as dry or cooked form, gives the excellent complexion and goodness to the body, as

if the person consumes regular fruit and mercurial drugs. It contains polysaccharides and flavonoids that are potent antioxidants. Aloe

is an excellent example of a functional food that plays a significant role in protection from oxidative stress.[32]

When Solanum nigrum (Manathakkali keerai) taken as curry, dry vatthal or decoction yields extraordinary physical and mental

wellness. A potential role of the antioxidants present in S.nigrum plant extract as a supplemental nutritional therapeutic agent in the

disorders related with the free radical damage. The results also indicate that S. nigrum extract could serve as a dietary supplement to

combat various neurodegenerative diseases [33]

.

In Limonia acidissima (Vila), all parts including leaf, unripe fruit, fruit, bark, root are to be consumed as curry or in a

decoction form to prevent ageing and death. Limonia acidissima, contains polysaccharides and triterpenoids in enormous amount

which exhibits high antioxidant and having free radical scavenging activity [34]

.

Different phytochemical studies on Cyperus rotundus (Korai kizhangu) revealed the presence of alkaloids, flavonoids,

tannins, starch, glycosides, furochromones, monoterpenes, sesquiterpenes, sitosterol, fatty oil containing a neutral waxy substance,

glycerol, linolenic, myristic and stearic acids [35]

. Oral daily administration of 500 mg/Kg of the extract (Once a day for seven

consecutive days) significantly lowered the blood glucose levels in rats with alloxan-induced diabetes. The scientists concluded that

this anti-hyperglycemic activity can be attributed to its antioxidant activity as C.rotundus showed a strong 1,1-diphenyl-2-

picryihydrazyl (DPPH) radical scavenging action in-Vitro [36]

.

Withania sominifera (Amukara) root powder mixed with ghee or milk taken twice a day improves fertility, reduces nervous

debility, strengthens the body and enhances longevity of life. Amukkara contains the ergostane-type steroidal lactones, including

withanolides A to Y, dehydro withanolide R, withasomniferin A, withasomidienone, withasomniferols A to C, withaferin A, and

withanone. Other constituents include the phytosterols sitoindosides VII to X and beta-sitosterol as well asalkaloids (for example,

ashwagandhine, cuscohygrine, tropine, pseudotropine, isopelletierine, and anaferine), a variety of amino acids (including tryptophan),

and high amounts of iron [37]

. A double-blind, randomized, placebo controlled study of the effects of Ashwagandha on stress found

that it reduced symptoms of stress and inability to concentrate and reversed forgetfulness in a dose-dependent manner, and 500

mg/day was more effective[38]

.

Basella alba (Kodi Pasalai) leaf can be prepared as curry and to be taken along with diet is said to promote sexual desire and

strengthen the body. It has high values of total phenol, flavanoids and ascorbic acid content and has antioxidant activity [39]

. Some

unique constituents of the plant are basellasaponins, kaempherol and betalain. Anthocyanins are a natural pigment that is responsible

for the blue, purple, violet and red colours in fruits, flowers, stem and leaves. Anthocyanin pigments are reported to have many

therapeutic benefits including vasoprotective and anti-inflammatory properties, reversing age related deficits and useful in controlling

oxidative stress [40]

.

Mushrooms have been utilized in folk medicine since ancient time. The species of mushrooms used varied in different

cultures, i.e. more species have been used in China and Japan than in Western Cultures. In China, where mushrooms are considered

the elixir of life, mushrooms have played an important us in medicine for as far back as 7,000 years. Numerous species are recognized,

including Lentinula edodes, Hericium erinaceum, Flammulina velutipes, Auricularia polytricha and Tremella fuciformis, to name a

few, and these are species that are also prized for eating, as well. Cordyceps sinensis species is commonly called the Caterpillar

Fungus and has probably been the most extensively studied species. It has properties similar to ginseng and is said to be more potent.

It is also believed to be a remedy for weakness and fatigue, often used as a "rejuvenator" for increase in energy. Successful treatment

for impotence, acting as an aphrodisiac has also been demonstrated in clinical human testing [41, 42,43]

.

Potato (Solanum tuberosum) serves as major, inexpensive low-fat food sources providing energy (starch), high-quality protein, fiber,

and vitamins. Potatoes also produce biologically active secondary metabolites, which may have both adverse and beneficial effects in

the diet. These include glycoalkaloids, calystegine alkaloids, protease inhibitors, lectins, phenolic compounds, and chlorophyll [44]

.

Naturally occurring benzodiazepines have been identified in regular food such as wheat and potato, potato extracts can affect CNS

responses in vivo. In this study potato juice as well as potato taken as food may have the capacity of influencing brain GABA-ergic

activity [45]

.

Pumpkin (Cucurbita maxima) juice can be applied over the body and the vegetable can be taken as curry. It balances the

body heat and strengthens the body. Xia & Wang demonstrated the hypoglycemic action of pumpkin (fruit) extract as well as its role

as an antioxidant to reveal a mechanism for its cyto-protective (cell-protecting) action in streptozotocin-induced diabetic animals [46]

.

Diets high in pumpkin seeds have also been associated with lower risk of gastric, breast, lung and colorectal cancers [47]

. The

carotenoids from pumpkin fruits have been linked to the prevention of prostate cancer [48, 49]

. Boiled pumpkin juice significantly

suppressed the incidence of aberrant cells while fresh pumpkin juice enhanced it [50]

. It was reported that pumpkin fruit extracts

markedly reduced tumour weight in S-180-bearing mice [50]

. Pumpkin may ease depression too, because the seeds contain L-

tryptophan, which raises levels of serotonin in the brain [51]

Eclipta prostrata (Kaiyaan) dry powder has to be taken with tender coconut water for one month and then one month with

honey. This strengthens the body and avoids premature aging. Further, it has enzymatic and non-enzymatic antioxidants such as

ascorbic acid and rutin [52]

. Eclipta prostrata has been used as a traditional medicinal plant to prevent dementia and to enhance memory

in Asia. It‘s potential as a nootropic and as an antioxidant has been reported in mice [53]

.

The stem part of Cissus quadrangularis contains vitamin C, carotenoids, calcium and steroids, which are known to be potent

antioxidants. In the β-carotene linoleic acid system and in the 1, 1-diphenyl-2-picrylhydrazyl system, Cissus quadrangularis Linn

stem extracts at a concentration of 100 ppm showed 64.8% and 61.6% of antioxidant activity respectively. The methanolic extract of

Cissus quadrangularis demonstrated significant inhibition in DPPH free radical formation, super-oxide radical production and lipid

peroxide production in erythrocytes [54]

.

Therapeutic karpam (Disease specific rejuvenators) There are numerous therapeutic karpa drugs, which are indicated for specified ailment. This section deals with the possible

karpa drugs that can be used in dementia.

Calotropis gigantea (Erukku) whole plant is powdered and can be taken with dry ginger, long pepper, and black pepper seed

with water will cure vatha, pittha and kapha diseases respectively. C.procera (50,100,200 mg/kg bodyweight i.p) significantly reduces

whole brain AchE activity indicating it as a potential anti-cholinesterase agent [55]

.

Phyllanthus amarus (Kizhkai-nelli) whole plant is prepared as paste and to be taken with milk/butter milk for 40 days with

avoidance of tamarind and salt. This is specific for ophthalmic diseases, liver disorders, giddiness and vomiting. In a study conducted

by Joshi et al 2007, the plant aqueous extract when administered for 9 days to young and older mice showed significant reduction of

brain acetylcholinesterase activity thereby probably facilitating cholinergic transmission and improving memory of animals [56]

. The

memory improving activity Phyllanthus amarus may be attributed to its antioxidant, neuro protective and memory enhancing activity,

suggesting that the plant might have chemical constituents, which possess nootropic activity, and having the ability to improve or

ameliorate short-term memory loss by the regulation of the antioxidant system [57]

.

Terminalia chebula (gall-nut, Kadukkai) powder can be taken for 48 days with water in the evening time relieves jaundice,

ascites and mental diseases like delusions. T. chebula plant extracts, which demonstrated potent free radical scavenging properties

particularly those showed EC50 < 10 μg/ml expected to play a vital role in reducing the oxidative stress and this, may explain their use

in traditional medicine for improvement of AD and/or ageing related diseases [58]

.

Due to vitiation of Azhal the ulcers appearing in the lips can be treated by mixing cumin seeds (Cuminum cyminum) with

country brown sugar can be taken as internally, which will reduce the elevated azhal kutram. Previous in-vivo study showed memory-

enhancing activity of C.cyminum in normal and scopolamine-induced amnestic rats, supporting for the anti-stress, antioxidant, and

memory-enhancing activities [59]

. Aqueous extract of C. cyminum seed inhibited AChE in concentration dependent manner. It

illustrates the fact that C.cyminum can acts as an inhibitor of AChE, helpful in enhancing memory and other cognitive functions of

brain [60]

.

Centella asiatica (Vallarai) leaf can be used as curry daily. It can also be taken along with common salt for 40 days. It is used

in liver disorders, enhances memory, intelligence and strengthens the body. It is found to reduce adrenal corticosterone levels in blood

on stress and is beneficial for cognitive and nervous illnesses as well as cerebro-vascular complications. It was proven its effect in

preventing the cognitive deficits and can be a free radical scavenger [ 61,62,63]

.

Either the decoction or the food item prepared by clearing nut or amla fruit (Strychnos potatorum or Phyllanthes embelica) as

given in the literature will cure body heat, anaemia, ascites etc. The lignan-glycosides vanprukoside, strychnoside, and

glucopyranoside isolated from Strychnos vanprukii have shown significant antioxidant property [64]

.Anwala churna (Nellikkaai) may

prove to be a useful remedy for the management of AD because of its multifarious beneficial effects such as its memory improving

property, cholesterol-lowering property and anticholinesterase activity [65]

.

The oil prepared with Thulasi known as Holy basil (Ocimum sanctum), plant is used to apply on the head while taking bath,

helps to cure pittha-accompanied diseases. This plant extract has been shown to possess anti-inflammatory, antioxidant and cognition-

enhancing properties [66]

. Thulasi treatment enhanced the antioxidant status in discrete regions of brain and the phytochemical contents

of thulasi have been suggested to be responsible for this effect. The plant is capable of promoting a healthy aging due to its multiple

but complimentary and synergistic medicinal properties, which can combat a diverse spectrum of disorders associated with aging [67]

.

The medicinal oil or decoction prepared from bael tree fruits and root helps to cure decreased consciousness and iya diseases. While

using, it strengthens the body and gives exquisiteness. A significant source of phenolics and flavonoids present in A. marmelos

effectively inhibits AChE activity and multiple components of the oxidative stress pathway that can contribute to Alzheimer‘s

pathology [68]

.

If we intake the green called Amaranthus gangeticus (sirukeerai) as food with seasoning of salt, pepper and ghee, it provides

mental sharpness, and body stamina. The chemical constituents responsible for antioxidant activity are carotenoids, ascorbic acid,

flavonoids and phenolic acids. Betacyanins, the coloring pigments present in the plant, have been reported to possess their antioxidant

and radical scavenging properties for protection against certain oxidative stress-related disorders [69]

.

If the lemon juice or salted lemon is taken daily for 6 months regularly with strict adherence of karpa dietary customs, the greyness of

hair, mental impedance, insanity will be cured. It also rejuvenates the body. Lemons are a rich source of vitamin C, providing 64% of

the Daily Value in a 100 g serving. Fruit extracts have also shown good antioxidant activity [70]

Role of Physical and intellectual exercises in anti-aging The principal uses of antiaging effects in older adults include lessening of stress, prevention of diseases while aging, memory

enhancement and treatment of various neuropsychiatric disorders, such as depression, anxiety, insomnia, pain and many other specific

symptoms [24]

. Some of the clinical and preclinical studies validate that exercise targets many features of brain function providing brain

healthiness. The benefits of exercise in the elderly populations are by the protection from neurodegeneration and alleviation of

depression. Exercise upsurges synaptic plasticity by directly affecting synaptic configuration and improves the potentiality of synaptic

strength. It further strengthens the underlying systems that help to improve plasticity such as neurogenesis, metabolism and vascular

function. The hippocampus is the most affected part of brain induced by exercise, which leads to structural and functional change. [71]

.

Systematic data confirms that the mindful physical exercises cure insulin resistance, hypertension, cardiovascular disease, and

depression and anxiety disorders [72]

. Clinical effects of meditation alleviate reduced anxiety, pain and depression, enhanced temper

and self-esteem, and decreased stress. Meditation practice can absolutely influence the experience of chronic illness and can serve as a

multi-level prevention strategy. Further controlled trials of yoga practice have demonstrated improvements in mood and quality of life

for elderly, people caring for patients with dementia [73]

. The longevity of an organism clearly depends on its individual parts and their

effective organization. The intercellular organization can be made effective with help of karpa medicines, and by practicing special

regimens like pranayama, yoga and meditation. A belief system at its core, Siddha medicine has immense faith in the mercurial drugs

and in the prolongation of life through rejuvenating treatments and intense yogic practices, among which regulated breathing has pride

of place [10]

. Mind-body exercise such as yoga couples sustained muscular activity with internally directed focus, producing a

temporary self-contemplative mental state. It also triggers a neuro-hormonal regulation that leads to healthy living, evidenced by the

suppression of sympathetic activity. Thus, it reduces stress and anxiety, progresses autonomic and higher neural center functioning [74]

.

Thokkanam (Massage therapy) Massage can be defined as the manual manipulation of soft tissue, performed by a person other than the recipient, intended to

promote health and well-being. In Siddha system, the Tamil word Thokkanam denotes that skin application. Applying medicated oils

with specified pressure on the surface of the body is used to stimulate varma points. Pathartha guna chinthaamani, Theran tharu are

the literatures that deals with the thokkanam methods. It is to regulate the accumulated praana force in the affected part of the body. It

is done by nine different methods as indicated in theran tharu text. Rubbing with medicated oil, striking with fist, pressing the body

parts, tightening the body are some of the common methods used in massage technique. It is used to relive mental stress, musculo-

skeletal pain, rheumatic pain and nerve compression pain etc. The literature specifies that the massage makes the body strong, relives

pain, improves fertility, skin gets radiance and the person gets sound sleep. Today‘s modern science discovered the massage therapy to

cure many diseases provoked by psychiatric disorders. They discovered that it regulates lymphatic channels to facilitate uninterrupted

lymph flow. After performing massage, the blood levels of tryptophan, serotonin and melatonin are increased. It eventually leads to

improvement in sleep in geriatric individuals. This method has many positive influences on the nervous system. On brain, the

massage improves the following

1. Subconscious mechanisms are certainly involved; however, which ones are unidentified. The reciprocal interplay between the

body and mind is evident

2. Reducing pain may be a subconscious effect on the parts of the brain associated with pain and emotions (tautological argument,

very weak30); Dampen central pain perception processing 3. Increased dopamine and serotonin along with decreased cortisol levels and lowers serum cortisol levels.

[75]

Suzuki et al, 2010 has reported the effects of tactile massage on changes in cognitive function and BPSD in the everyday life

of elderly patients with severe dementia through a 6-week course of tactile hand massage. The results of this study showed a

significant reduction on the GBS for both intellectual function and emotional function in the control and interventional groups. In this

study changes in salivary CgA measurements, used as a stress index, which showed reduction in stress after intervention [76]

.

A 30-minute back massage for 5 days to 52 hospitalized depressed and adjustment disorder children and adolescents were

less depressed compared to control and had lower saliva cortisol levels after massage. They were less anxious and more co-operative

and increased nighttime sleep was reported [77]

.

Siddha mechanism to treat psychiatric diseases In Siddha System, there were number of ways to administer drug for epileptic, unconscious and schizophrenic individuals.

Siddha vaithiyars used blowing of herbal medicines into eyes, nose and ears to unconscious snake bitten person to get him up. The

drug nullifies venom by counter-acting or eliminating the neurotoxic and vasculotoxic effects in rapid way, indicates that these modes

of drug delivery can cross biological barriers but oral route of administration may not. The biggest challenge to drug delivery into the

CNS is bypassing the blood-brain barrier (BBB) as it limits access to the CNS. For decades, the BBB has prevented the use of many

therapeutic agents for treating brain-related diseases and injuries, including AD, stroke, brain tumor, head injury, and other CNS

disorders [78]

. Nasiam, an intra-nasal drug delivery in Siddha is practiced for its rapid, non-invasive action because the unique

relationship between nasal cavity and cranial cavity tissues in anatomy and physiology makes intranasal delivery to the brain feasible.

Existence of a direct transport route from the nasal cavity to the brain, bypassing the BBB, would offer an exciting mode of delivering

neuro therapeutic agents. The nasal mucosa has a rich vasculature and, therefore, offers greater permeability than any other mucosal

surfaces of the body. The nasal route offers faster drug absorption as it bypasses the hepatic first pass metabolism [79]

. Likewise, the

other modes such as kalikkam, anjanam etc might bypass BBB and act on CNS. It implies that Siddha lineages are competent in

administering medicines to psychiatric individuals.

DISCUSSION

Alzheimer's disease and multi-infarct dementia are progressive illnesses, and up to now, there is no effective treatment. It is

best to distinguish the symptoms timely and be diagnosed and assessed by a doctor. There are currently some modern medications

available to slow the progress of disease. The review of above siddha practices with contemporary evidences states that these

approaches can be used to prevent complications of aging up to considerable extent and gives appropriate hints for the effective

management of age related cognitive insufficiencies. The holistic approaches in Siddha system can be able to alleviate the progression

of senile dementia. Thus, the Siddha therapeutic package which consists oral medicines, siddha psychiatric treatments, massage and

attanga yoga physico-intellectual exercises are having the potential to check the cognitive decline in elderly and these can be used to

improve their quality of life. The general and therapeutic rejuvenators, kirigai maruthuvam practices given in the Siddha literatures,

which are elapsed techniques from current day practice because of its complexity, can be used as effective mode of management.

Dementia is progressive, which means the symptoms will steadily get worse. These set of therapies including oral intake of kayakarpa

drug with the practice of yogic techniques, combined with regular body massage stimulation will certainly moderates the disease

progression.

CONCLUSION

The age-old literary evidences conjoin with current scientific proofs, which form a new pathway of treatment procedure for

dementia. The usage of herbal treatment for dementia gives future hope for the discovery of targeted drug action in a naturalistic way.

There is a need of holistic approach in the dementia patients with more person-centered form of care. Siddha system indeed caters this

set of circumstances. The above therapies would protect or may reduce the risk for dementia that is important for controlling this

distressing disease. Further, it is essential to standardize these therapies for systematic use in dementia individuals.
