Stroke and TIA - Summary
• Strokes and transient ischaemic attacks (TIAs) are acute
neurological events, presumed to be vascular in origin, that are
caused by cerebral ischaemia, infarction, or haemorrhage.
• Symptoms and signs develop rapidly, are usually focal, and
include numbness, eakness or paralysis, slurred speech, and
visual disturbances. !eadache is not a typical feature of
ischaemic stroke or TIA.
o "ith stroke, the symptoms and signs persist beyond
#$ hours or cause death ithin #$ hours.
o "ith TIA, the symptoms and signs resolve ithin
#$ hours.
• Strokes can be classi%ed by their main causes as either
ischaemic (&' of cases) or haemorrhagic (' of cases).
• Stroke is the third most common cause of death in the *+.
ost strokes occur in people older than ' years, but they can
occur at any age.
• The complications and conseuences of stroke are numerous
and include neurological problems, depression and an/iety,
speech and communication di0culties, and di0culties ith
activities of daily living.
•
The risk of recurrent vascular events varies considerablyamong individuals and depends on the underlying pathology,
comorbidities, and lifestyle factors.
• anagement of a suspected acute stroke in primary care
includes urgent admission (ithin one hour) to a specialist stroke
unit1
o Antiplatelet treatment should not be started until
haemorrhagic stroke has been ruled out by a brain scan.

o If the person is eligible for thrombolysis (up to hours
from the start of the symptom), the ambulance control should
be informed so that the person is taken immediately to the
nearest specialist stroke unit for stroke thrombolysis.
• After a stroke, follo up should be arranged ithin eeks of
discharge and then annually to1
o Assess the need for further specialist revie, advice,
information and support.
o Assess social care and health care needs.
o 2heck and optimi3e lifestyle measures, and drug
treatments for secondary prevention of cardiovascular disease.
• anagement of a TIA in primary care includes assessing the
risk of an early stroke using the A425# scoring system.
• If the person is at high risk of an early stroke after a TIA they
should be1
o 6eferred for specialist assessment ithin #$ hours of the
onset of symptoms.
o 7iven an antiplatelet and a statin.
• If the person is at lo risk of an early stroke after a TIA they
should be1
o 6eferred for specialist assessment as soon as possible,
but de%nitely ithin one eek of onset of symptoms.
o 7iven an antiplatelet and a statin.
• After a TIA, follo up should be arranged ithin month (in
primary or secondary care) and then annually in primary care to
check and optimi3e lifestyle measures, and drug treatments for
secondary prevention of cardiovascular disease.

5e%nition
"hat are strokes and transient ischaemic attacks8
• Stroke is de%ned as a clinical syndrome, caused by cerebral
infarction or haemorrhage, typi%ed by rapidly developing signs of
focal and global disturbance of cerebral functions lasting more
than #$ hours or leading to death.
o Non-disabling stroke is a stroke ith symptoms or
signs that last for more than #$ hours but resolve later, leaving
no permanent disability.
o Disabling stroke is a stroke hich leaves the person
unable to carry out all their usual activities.
o Minor stroke is stroke ith fe mild symptoms on
initial assessment.
o Subarachnoid haemorrhage although it is classi%ed
as a type of stroke, subarachnoid haemorrhage is not usually
included in guidelines on stroke diagnosis and management.
o Stroke with rapid recovery can only be distinguished
from a transient ischaemic attack (TIA) retrospectively and,
apart from guiding investigation to e/clude other conditions, is
of little clinical importance.
• Transient ischaemic attack is de%ned as an acute loss of
cerebral or ocular function ith symptoms lasting less than #$hours caused by an inadeuate cerebral or ocular blood supply as
a result of lo blood 9o, ischaemia, or embolism associated ith
disease of the blood vessels, heart or blood.
o The symptoms and signs of a TIA usually resolve ithin
minutes, or may last a fe hours. Therefore, people ho have
continuing neurological signs hen %rst assessed should be
assumed to have had a stroke.

2auses and classi%cation
2auses and classi%cation of strokes
Strokes can be classifed by their main causes as either
ischaemic (most common) or haemorrhagic
• !schaemic stroke"
o Ischaemic strokes are caused hen a blood vessel in the
brain is blocked, for e/ample by a blood clot or by the fatty
material from an atherosclerotic plaue. The brain cells in the
part of the brain served by the a:ected blood vessel die of lack
of o/ygen and nutrients.
o There are to main types of ischaemic stroke ;
thrombotic and embolic1
Thrombotic ischaemic stroke ; a blood clot
spontaneously forms in an artery in the brain. This is a
common complication of atherosclerosis.
#mbolic ischaemic stroke ; part of the fatty
material from an atherosclerotic plaue or a clot in a larger
artery or the heart breaks o: and travels donstream until it
is trapped in a narroer artery in the brain.
8/18/2019 Stroke and TIA Notes
5/51
Subarachnoid haemorrhagic stroke ; there is
bleeding from a blood vessel beteen the surface of the
brain and the arachnoid tissues that cover the brain.
o Some e/perts do not classify subarachnoid haemorrhage
as stroke because subarachnoid haemorrhages present
di:erently from ischaemic strokes and intracerebral
haemorrhagic strokes, and they reuire particular
management. !oever, both acute strokes and subarachnoid
haemorrhages need emergency admission. So, regardless of
hether subarachnoid haemorrhage is considered stroke, the
primary care management is the same.
• About &' of strokes are ischaemic, and about ' are
haemorrhagic.

After a TIA1 risk (longer term) of 2?5 events
After a TIA, what is the longer-term risk of subsequent
cardiovascular disease events and death?
• 2on%rmed episodes of transient ischaemic attack (TIA)
indicate established cardiovascular disease, ith an increased
risk of future cardiovascular events. Holloing an initial TIA, it has
been estimated that @"arlo and 5avenport, DD Adams et al,
#CB1
o The annual risk of myocardial infarction is #JC, and
C' of people ho have had a TIA ill eventually die of cardiac
disease.
o The combined risk of stroke, myocardial infarction, or
vascular death is about D per year.
o About #J$ of people ho have had a TIA or
ischaemic stroke have asymptomatic coronary heart disease.
• A study of #$$E people enrolled in the 5utch TIA trial (ith a
mean of ' years of age) found that over a mean of years @van"iKk et al, #'B1
o Appro/imately had died.
o Almost '$ had e/perienced at least one ne vascular
event.
o After the %rst C months, the risk of a further vascular
event declined over the ne/t C years, but then increased overthe folloing years. The authors noted that this could be due to
poor compliance ith drugs and less care being taken over
lifestyle issues, as ell as increasing age.

• !mpaired tone 9 spasticity and spasms"
o Anyone ith motor eakness after a stroke should be
assessed for spasticity.
There is considerable debate on the de%nition,
physiology, and importance of spasticity.
Hor clinical purposes, consider spasticity to be a
problem if there is increased tone, abnormal posturing, or
involuntary spasms, and if this causes discomfort or limited
activity for the person or di0culty for the carer.
o Spasticity can be treated by1

Always consult the latest Driver and Vehicle Licensing Agency (DVLA) regulations to ensurethat your advice is accurate and up to date — see the 'At a Glance' booklet available on
the DVLA website.
• 'or people with a group !! licence 9 &or large goods
vehicles or passenger carrying vehicles 9 who have had a
transient ischaemic attack (T!*)"
o They must notify the 5?GA, ho ill not allo them to
drive under this licence for at least # months.
o They can be considered for re-licensing after this period
provided that they have no other signi%cant risk factors.
6e-licensing ill also be subKect to satisfactory
medical reports, including e/ercise electrocardiography.
"here there is imaging evidence of essentially
normal carotid arteries 7roup II licensing may be alloedithout the need for functional cardiac assessment.
• 'or people with a group ! licence 9 an ordinary driving
licence &or car or motorcycle 9 who have had a T!*"
o They must not drive for at least $ eeks.
o >eople ho have multiple TIAs over a short period
should notify the 5?GA of this the 5?GA ill reuire at leastC months free of further attacks before alloing driving to be
