    Reason

    The reason my group choose this topic for our research paper is for three reasons. One

    reason was the availability of information; it is easy to find information on the topic. Secondly was

    the topic seemed very interesting because from the research we have collected at least two people

    from this group will have Alzheimers disease as we age. Lastly was at least three of us from the

    group have relatives with this disease and would like to know what at least is going on so we may

    be some use to them. From this research paper we have learned a lot and this information we have

    learned is irreplaceable.

    Concept

    Alzheimers disease is a brain disorder named for German physician Alois Alzheimer, who first

    described it in 1906. Alzheimer's destroys brain cells, causing memory loss and problems

    with thinking and behavior severe enough to affect work, lifelong hobbies or social

    life. Alzheimers disease accounts for 50 to 70 percent of dementia cases. Other types of dementia

    include vascular dementia, mixed dementia, dementia with Lewy bodies and front temporal

    dementia. The brain has 100 billion nerve cells (neurons). Nerve cell networks have special jobs.

    In Alzheimers disease, as in other types of dementia, increasing numbers of brain cells deteriorate

    and die. Plaques build up between nerve cells. Tangles form inside dying cells. Scientists are not

    absolutely sure what role plaques and tangles play in Alzheimers disease.

    Causes

    Scientists are still trying to fully understand the cause or causes of Alzheimers disease. In

    the meantime, its said to be helpful that we understand the hallmarks of Alzheimers plaques and

    tangles and the risk factors that affect a persons likelihood of developing the disease. Alzheimer's

    disease is characterized by a build-up of proteins in the brain. Though this cannot be measured in a

    living person, extensive autopsy studies have revealed this circumstance. The build-up manifests

    in two ways. Plaques which are deposits of the protein beta-amyloid that accumulates in the spaces

    between nerve cells. Another way this build up can occur is through tangles, which are deposits of

    the protein tau that accumulate inside of nerve cells. Scientists are still studying how plaques and

    tangles are related to Alzheimers disease.

    One theory is that they block nerve cells ability to communicate with each other, making it

    difficult for the cells to survive. It is likely that the causes include genetic, environmental, and

    lifestyle factors, because people differ in their genetic make-up and lifestyle, the importance of

    these factors for preventing or delaying AD differs from person to person. Autopsies have shown

    that most people develop some plaques and tangles as they age, but people with Alzheimers

    develop far more than those who do not develop the disease.

    Scientists still dont know why some people develop so many compared to others.

    However, several risk factors for Alzheimers disease have been uncovered. Genetics play a role in

    some people with AD. A rare type of AD, called early-onset AD, affects people ages 30 to 60.

    Some cases of early-onset AD, called familial AD, are inherited. Familial AD is caused by

    mutations (permanent changes) in three genes. Offspring in the same generation have a 50-50

    chance of developing familial AD if one of their parents had it.

    Advancing age is the number one risk factor for developing Alzheimers disease. One out

    of eight people over the age of 65 have Alzheimers disease, and almost one out of every two

    people over the age of 85 has Alzheimers. Facts and studies show that the probability of being

    diagnosed with Alzheimers nearly doubles every five years after age 65. People who have a

    parent or sibling that developed Alzheimers disease are two to three times more likely to develop

    the disease than those with no family history of Alzheimers. If more than one close relative has

    been affected, the risk increases even more.

    Scientists have identified two kinds of genes that are associated with this familial risk

    factor. The first is thought to be a risk gene, ApoE 4, that increases the likelihood of developing

    Alzheimers, but does not guarantee it. In addition to ApoE 4, scientists think there could be up to

    a dozen more risk genes yet to be discovered. The second kind of gene is a deterministic gene

    and is much rarer than risk genes. Deterministic genes are only found in a few hundred extended

    families around the world.

    If a deterministic gene is inherited, the person will undoubtedly develop Alzheimers, but

    probably at a much earlier age. Although age and family history are out of our control, scientists

    have also identified several lifestyle factors that can influence a persons risk of developing

    Alzheimers disease. A connection has been found between serious head injury and future

    development of Alzheimers, so those who practice safety measures such as wearing seat belts and

    not engaging in activities where there is a high risk of falling are at an advantage. Evidence states

    that there should be a greater promotion of exercise and a healthy diet, to help reduce Alzheimers

    risk.

    Avoiding tobacco, limiting alcohol consumption, staying socially active, and engaging in

    intellectually stimulating activities, have also been shown to have a protective effect against

    Alzheimers disease. Finally, there is a strong link between heart health and brain health. Those

    who are free of heart disease or related conditions are at a lower risk of developing Alzheimers or

    another kind of disease than those who have cardiovascular problems.

    Signs and Symptoms of Alzheimers disease

    Alzheimers disease is the most common forms of Dementia. Alzheimers disease is a

    serious brain disorder that impacts daily living through memory loss and cognitive changes. Some

    common signs of Alzheimers disease can be mixed up with normal everyday normality of

    forgetfulness. Early stages of Alzheimers can be detected mainly by memory loss regarding

    recent conversations and events. It can start off as routinely placing important items in odd places,

    forgetting names of family members and common objects. It also is a result of, repeated questions,

    forgetting the way to get to a frequent visited place and even the inability to following simple

    directions for a recipe. This stage can usually last from 2-4 years.

    Moderate to middle stage Alzheimers disease is usually discovered when they can no

    longer cover up problems, have rambling speech, unusual reasoning, and have problems with

    places and times. Constant reminders are needed; assistance is needed with daily living activities,

    mood and behavioral changes start to occur and about 80% of patients show evidence of emotional

    and behavioral problems which are aggravated by stress and change that they are not used to.

    This Stage can last from 2-10 years.

    Severe to Late stage Alzheimers is the result of confusion of the past and present. Another

  • 8/8/2019 Alzheimer Fixed)

    8/24

    8

    sign is severe to total loss of verbal skills, they forget to speak or how to speak or write. The

    person becomes completely incapable to care for self. They become very high risk to falling due

    to gait dysfunction, and become bedridden. Patients begin to hallucinate, have severe mood

    swings and behavioral issues. They tend moan and cry when unable to express what they are

    feeling at the moment. They become totally dependent on others and need total support and care.

    They can end up with issues such as the inability to swallow, incontinence, and illness. Illness is

    the result of the body systems shutting down usually resulting in death. To sum up the basic

    important information about Alzheimers disease one should the top ten basic signs to detect

    Alzheimers.

    First Sign is memory loss. We all experience it one way or another; it is just a matter of

    knowing the difference between a slip-up and long-term forgetfulness. It is natural to forget an

    appointment and/or a persons name but to later remember it. Second basic sign of Alzheimers is

    challenges arising when planning or solving problems. We can easily make a mistake while

    balancing our check book every once in awhile but forgetting to pay monthly bills can be a sign to

    a serious condition. Third sign of possible Alzheimers disease is difficulty in completing familiar

    tasks at home. Of course we forget what button to press when wanting to TiVo something but

    forgetting the rules to your all time favorite board game, theres obviously a problem.

    The fourth simple sign to detect Alzheimers disease is confusion time and place.

    Obviously we can occasionally forget what day of the week it is but we always remember in the

    end, whereas forgetting where we are and having no clue how we got there. These situations can be

    very stressful. The fifth sign of Alzheimers is trouble understanding. Alzheimers prospect begins

    having visual problems creating difficulty with reading. Over the years, with age, it is common to

    be diagnosed with cataracts, which at this time would be natural to have difficulty reading or

  • 8/8/2019 Alzheimer Fixed)

    9/24

    9

    seeing.

    The sixth sign of Alzheimers is having trouble with speech i.e. speaking and writing. It

    creates difficulty in joining in on conversations happening around them and or even while theyre

    speaking they stop because they do not recall the subject of the conversation. We can be in the

    middle of a conversation and be distracted by something but as long as we are reminded by just a

    simple word. The seventh sign of Alzheimers is misplacing things and the inability to retrace ones

    steps to remember. Its normal for us to misplace the remote or even our car keys time to time but

    to place our common everyday items in awkward places is a little sign of Alzheimers.

    The eighth sign of Alzheimers disease is decreased or poor judgment. It is normal for us

    to every once in a while make bad decisions and Alzheimers prospects pay less attention to their

    personal hygiene or can even pay people such as telemarketers large sum of money due to poor

    judgment with money. The ninth sign of Alzheimers disease is withdrawal from work or social

    activities. We are always at fault for feeling weary from work and wanting to be alone not having

    to go social gatherings or family gatherings from time to time. It is perfectly normal. An

    Alzheimers prospect will begin to withdraw from their favorite hobbies and forget how their

    favorite teams play. They can begin to feel that they dont want to participate in anything anymore

    and become lonely.

    The final sign of Alzheimers is the change in mood and/or personality. The prospect can

    become depressed, confused and even suspicious. We can usually create a routine of how we do

    things and when they get interrupted we can become irritated and frustrated and it is perfectly

    normal on occasion.

    Diagnosis

    10/24

    10

    Alzheimers disease causes physical change in a persons brain that cannot be properly

    diagnosed until being closely examined. Physicians are able to diagnose Alzheimers with 90%

    accuracy due to thorough examination. Several of these medical examinations include the patients

    history, a mini-mental state exam, specific laboratory testing, and certain neuro-imaging

    examinations (Beers and Berkow). By gathering certain information from these exams, a doctor

    can identify if a patient suffers from Alzheimers and what stage of Alzheimers the patient is

    currently in.

    For further explanation, a doctor will ask a series of questions to compose a medical

    evaluation of the patient. The questions asked as part of the patients history includes information

    of the problem occurring, a history of current illnesses, and any family history in regards to the

    occurring problem. Physicians perform mini-mental exams that focus on the patients attention

    span, memory and other types of mental moods. For instances, the doctor performing the exam

    will try to interpret the different mood swings the patients undergoes. Another example would be

    the attitude, behavior and appearance towards other people. Specialists evaluate patients on the

    following statuses: Cognition, Insight judgment, Speech and language, Thought content, and

    Thought processes.

    After the physician has performed several mental tests, they usually send the patient to a

    laboratory to have blood work done. Even though there is not a specific lab test that can identify

    Alzheimers, the physician tries to rule out the possibility of other diseases by checking the levels

    of certain chemicals in the body. Specialist analyze the levels of Vitamin B12, TSH (for the

    thyroids), CBC (for anemia), and HIV. Furthermore, depending on the conditions of the patient,

    the next step to evaluate if the patient has Alzheimer is to perform several neuro-imaging exams.

  • 8/8/2019 Alzheimer Fixed)

    11/24

    11

    One of the main exams that a patient undergoes is a CT scan. A CT scan takes multiple X-ray

    pictures of a certain body part to analyze any major changes. Patients with possible Alzheimers

    carry out a CT scan of the brain, where specialist can observe changes in the size of the brain. A

    size reduction of the brain may be a result of Alzheimers. Another imaging exam will be an MRI,

    which shows the functional changes of the brain. MRIs also rule out the possibility of

    Alzheimers by observing if any tumors are present (Kasper, Braunwald and Fauci). As stated

    previously, a patient cannot be properly diagnosed with Alzheimers until further studies are done

    after the patients death. These are some of the methods to determine the possibility of a patient

    suffering Alzheimers. There is only one method that has been recently discovered to diagnose

    Alzheimers at 100% accuracy which is an autopsy on the brain.

    Treatments

    Although no cure for Alzheimers disease is yet available, medical and behavioral

    treatments for the disease may ease symptoms for the individual with Alzheimer's.T

    he symptoms

    that can be treated are the cognitive and behavioral symptoms. There is only three ways for treating

    symptoms of Alzheimers. They are the Standard Treatments, Sleep Treatments and lastly

    Alternative Therapy.

    Standard Treatments consist of two types of medications that have been approved by the

    U.S. Food and Drug Administration (FDA). The two types of drugs are cholinesterase inhibitors

    and Memanatine. Cholinesterase inhibitors are prescribed to treat symptoms related to memory,

    thinking, language, judgment and other thought processes. Three different cholinesterase

    inhibitors are commonly prescribed. Donepezil also called Aricept, which is used to treat all stages

  • 8/8/2019 Alzheimer Fixed)

    12/24

    12

    of Alzheimers disease. Galantamine also called Razadyne, used to treat mild to moderate stages

    of Alzheimers. Rivastigmine also called Exelon, usually used to treat mild to moderate

    Alzheimers. Tacrine also called Cognex, the first cholinesterase inhibitor, was approved in 1993

    but is rarely prescribed today because of associated side effects, including possible liver damage.

    Cholinesterase inhibitors work by increasing the levels of a chemical messenger involved

    with memory, judgment and other thought processes called acetylcholine. There are certain cells

    in the brain that produce or release this chemical messenger acetylcholine, which in fact actually

    help communicate between other cells. Upon this messenger reaching the receiving cell various

    other chemicals as well as an enzyme called acetyl cholinesterase appear. This enzyme acetyl

    cholinesterase breaks down acetylcholine so it can be recycled.

    However Alzheimers disease damages or worst yet destroys the cells that produce or use

    acetylcholine. As a result of this process reduces the amount of acetylcholine to carry messages.

    Cholinesterase inhibitor is actually an enzyme created to slow down the process of breaking down

    the acetylcholine. Cholinesterase inhibitor accomplishes this by blocking the activity acetyl

    cholinesterase. This process saves some acetylcholine from being destroyed by the Alzheimers

    disease. These medications help the brain work better but it doesnt stop or reverse the destruction

    of the brain cells. Cholinesterase inhibitors do not prevent Alzheimers from getting worst this is

    just a method to slow the progression down.

    Cholinesterase inhibitors seem to offer other benefits, as well. For example,

    Galantamine appears to stimulate the release of acetylcholine and to strengthen the way certain

    message-receiving nerve cells respond to it. Rivastigmine may block the activity of another

    13/24

    13

    enzyme involved in breaking down acetylcholine. In contrast if side effects occur, they commonly

    include nausea, vomiting, loss of appetite and increased frequency of bowel movements. It is

    strongly recommended that a physician who is experienced in using these medications monitor

    patients who are taking them, and that the recommended guidelines be strictly observed.

    Memantine also called Namenda is prescribed to improve memory, attention, reason,

    language and the ability to perform simple tasks. This was the first Alzheimer drug of the NMDA

    receptor antagonist type. Memanatine is used to treat moderate to severe Alzheimers only.

    Memantine works by regulating the activity of a chemical involved in information

    processing, storage and retrieval called glutamate. Perceptibly Glutamate triggers NMDA

    receptors to let a controlled amount of calcium into a nerve cell as a result of this process it

    significantly helps with learning and memory. The calcium helps creates the chemical

    environment required for information storage. In the same way Glutamate can be helpful it can be

    damaging. If there is excess Glutamate it over stimulates NMDA receptors so that they allow too

    much calcium into nerve cells. In a nut shell excess glutamate causes disruption and death of cells.

    However Memantine may protect cells by partially blocking NMDA receptors. Adverse

    side effects include headache, constipation, confusion and dizziness. Scientists have made

    remarkable progress in understanding how Alzheimers affects the brain. Their insights point

    toward promising new treatments to slow or stop the disease. Ultimately, the path to effective

    therapies is through clinical studies.

    The second treatment to help Alzheimers is sleep treatment. This is a significant factor of

    Alzheimers because doctors have not found the exact reason why this happens. Many people with

  • 8/8/2019 Alzheimer Fixed)

    14/24

    14

    Alzheimers experience changes in their sleep patterns. Similarly how Alzheimers affect memory

    and behavior, sleep changes also occur to Alzheimers patients. There have been cases of this in

    older adults without dementia who notice this as well. These conflicts occur more frequently and

    tend to be more brutal in Alzheimers patients. This is common in later stages of Alzheimers yet

    there have been reports and studies show to be found in the early stages as well.

    This seems hard to believe that such a thing as difficulty sleeping can be caused by

    Alzheimers. There are several patients with Alzheimers that wake up more often and stay awake

    longer during the night. Brain wave studies have shown to have a decrease in both dreaming and

    non-dreaming sleep stages. Sometimes those who cant sleep may be unable to lie still, or yell or

    call out, disturbing the sleep of their caregivers.

    Alzheimers patients have tendency for daytime napping and other shifts in the sleep-wake

    cycle. Individuals may feel very drowsy during the day and then be unable to sleep at night.

    Experts estimate that in late stages of Alzheimers, individuals spend about 40 percent of their time

    in bed at night awake and a significant part of their daytime sleeping. Patients should have a

    thorough medical examination to identify any treatable illnesses that may be contributing to the

    sleeplessness. Some conditions are Depression, Restless legs syndrome, Sleep apnea.

    Most doctors mostly try the non-drug treatment first due to the amount of medications

    patients usually are taking. This treatment aspires to build a sleep routine, to decrease daytime

    napping and to create the sleep environment necessary. The structure of this treatment consists of

    Maintaining a schedule for regular times for meals and for going to bed and getting up, Encourage

    regular daily exercise includes seeking morning sunlight exposure, Treat any pain, Avoid alcohol,

  • 8/8/2019 Alzheimer Fixed)

    15/24

    15

    caffeine and nicotine, If the person is taking a cholinesterase inhibitor avoid giving the medicine

    before bed, Make sure the bedroom temperature is comfortable, If the person awakens, discourage

    staying in bed while awake; use the bed only for sleep, Discourage watching television during

    periods of wakefulness.

    The second Sleep treatment is obliviously medications. This is for the cases that non-drug

    fails help the sleeplessness. There is one rule for delivering sleep medications all experts agree on

    begin low and go slow. This rule came about because of the risk of sleep inducing medication on

    older adults who are cognitively impaired are significant. The risks are increased risk for falls and

    fractures, confusion, and a decline in the ability to care for oneself. However once a sleep pattern

    has been established patients are too slowly discontinue them.

    The most common used sleep medications are Tricyclic antidepressants, such as

    nortriptyline and trazodone. Another is Benzodiazepines which common names are lorazepam,

    oxazepam and temazepam. Sleeping pills also called zolpidem, zaleplon and chloral hydrate.

    Lastly are antipsychotics such as haloperidol, risperidone, onlanzapine and quetiapine.

    The final treatment is alternative therapy which consists of several herbal remedies,

    vitamins and other dietary supplements. The safety and capability of these products are based

    fundamentally on testimonials, tradition, and a rather small body of scientific research.The reason

    this is called alternative therapy is due to the unknown. The effectiveness, safety, purity are all

    unknown. The claims do not present enough evidence of effectiveness for FDA, as well as FDA

    has no authority over supplement production. The safety of this therapy is also not regulated. The

    safety precautions are actually given by healthcare professionals to the manufacturers. Not to

    mention the risk of these products can have serious or serve interactions with prescribed

  • 8/8/2019 Alzheimer Fixed)

    16/24

    16

    medications.

    Vitamin E is used to treat Alzheimers because it is an antioxidant, a substance that may

    protect nerve cells from certain kinds of chemical wear and tear. There is one large federally

    funded study that shows that vitamin E can slightly slow down the loss of ability to carry out daily

    life. Patients should not take vitamin E to treat Alzheimers unless supervised by physician. The

    Vitamin E doses in these cases are relatively high. This high dose is why vitamin E should never

    been taken without proper supervision. Vitamin E can interact with other medications, including

    those prescribed to keep blood from clotting.

    Coenzyme Q10 or ubiquinone is another antioxidant that is used in Alzheimers patients.

    This usually naturally produced in the body and is necessary for ordinary cell reactions. There was

    a synthetic version of this compound called idebenone, which was studied with Alzheimers but

    produced complimentary results. There is also no information on an adequate dose to be taken and

    considered safe. Consequently there can be harmful effects due to the lack of study.

    Coral Calcium which is advertised as a cure for Alzheimers, cancer and other illnesses.

    This is a form of calcium carbonate that is derived from shells of formerly living organisms that

    made up coral reef. In June 2003, the Federal Trade Commission (FTC) and the Food and Drug

    Administration (FDA) filed a formal complaint against the promoters and distributors of coral

    calcium. Coral calcium differs from ordinary calcium supplements only in that it contains traces of

    some additional minerals incorporated into the shells by the metabolic processes of the animals

    that formed them. It contains no amazing health benefits.

    Ginkgo biloba is a plant extract containing several compounds. Ginkgo biloba is thought to

    have antioxidant and anti-inflammatory benefits that may have positive effects on cells within the

    brain and the body. However, multicenter Phase III study published in the Journal of the

  • 8/8/2019 Alzheimer Fixed)

    17/24

    17

    American Medical Association (November 19, 2008) proved that gingko was acting as a placebo

    in delaying changes in memory, thinking and personality and had no impact on the development of

    Alzheimers.

    Huperzine-A is a moss extract usually used in traditional Chinese medicine. The properties

    of Huperzine-A is very similar to those of cholinesterase inhibitors. As a result, it is promoted as a

    treatment for Alzheimer's disease also may be comparable to approved drugs for Alzheimers.

    There was a study for this drug launched in spring 2004 by no results has been mentioned. This is

    also another drug that has been regulated as a dietary supplement with no uniform standards. It is

    recommended not to be taken with prescribed medication due its similarity to cholinesterase

    inhibitors and increase side effects of prescribed drug.

    Last form of alternative therapy is Omega-3 fatty acids. Omega-3 is a type of

    polyunsaturated fatty acid it has been more linked to heart disease and stroke than Alzheimers.

    There are only two types of Omega-3s qualified for use. Docosahexaenoic acid (DHA) and

    Eicosapentaenoic acid (EPA) recently added to 75% of prenatal vitamins for develop of brain in

    babies. This fatty acid cannot be made in the body this is fatty acid primarily use from fish oil or

    flax oil. The reason why this was linked to the reduction of brain decline was that DHA is the chief

    omega-3 in the brain. There are theories that Omega-3s are might influence dementia risk include

    their benefit for the heart and blood vessels, anti-inflammatory properties, and support while

    protecting the nerve cell membranes. These findings are still under study and are in the preliminary

    stage.

    Appendix

    A.1 During the presymptomatic stage ofAlzheimer's disease (A), a beta accumulates in diffuse plaques.Axons and dendrites within and near the plaque appear structurally normal. By the symptomatic stage (B),

    many plaques appear "mature. Nearby microglia and astrocytes are activated, and axons and dendrites are

    degenerating.

    A.2 This illustration demonstrates a CT scan of the brain.

    Physicians are able to notice any changes of the brain to

    distinguish Alzheimers.
