Stroke Definition

Symptoms of stroke

Symptoms of the stroke typically start suddenly, over seconds to minutes,. The symptoms

depend on the area of the brain affected. The more the area of brain affected, the more

functions that are likely to be lost. Some forms of stroke can cause additional symptoms. For

example, in intracranial hemorrhage, the affected area may compress other structures. Most

forms of stroke are not associated with headache, apart from subarachnoid hemorrhage and

cerebral venous thrombosis and occasionally intracerebral hemorrhage

. If the area of the brain affected contains one of the

these central nervous system pathways— spinothalamic tract

corticospinal tract, and dorsal column (medial lemniscus,

symptoms may include:

1) there will be hemeplegia and weakness of the muscles of face

2) there is feeling of numbness

3) there is decreased in sensation.

4) Firstly there is flaccidity (hypotonicity), replaced by spasticity (hypertonicity), followed by

In most cases, the symptoms affect only one side of

the body i.e. .unilateral . Depending on the part of the brain affected, the defect in the brain

is usually on the opposite side of the body.

Brain stem give rise to 12 cranial nerves, stroke affecting the brain stem and

brain therefore can produce symptoms relating to defect in these cranial nerves:

There is total or partial loss of smell, taste, hearing, or vision.

Ptosis is common i.e.drooping of eyelid and weakness of ocular muscles

There is decreased reflexes: swallow, pupil reactivity to light

decreased sensation and muscle weakness of the face

nystagmus and balance problem is common

altered breathing and heart rate

patient is notable to turn head to one side because of weakness in

sternocleidomastoid muscle

due to weakness in tongue muscles there is difficulty in protruding or move side

If the cerebral cortex is involved following

symptoms can be seen

aphasia (difficulty with verbal expression, auditory comprehension, reading and/or

writing Broca's or Wernicke's area is commonly involved)

dysarthria (difficulty in speech)

apraxia (altered voluntary movements)

visual disturbances

memory deficits due to the involvement of temporal lobe

hemineglect due to the involvement of parietal lobe

disorganized thinking, confusion, hypersexual gestures because there is involvement

anosognosia (persistent denial of the existence of a, usually stroke-related, deficit)

If the cerebellum is involved, the patient may have the following:

difficulty in walking

altered movement coordination

vertigo and or disequilibrium

Associated symptoms

There is loss of consciousness, headache, and vomiting usually occurs more often in

hemorrhagic stroke than in thrombosis because of the increased intracranial pressure from

the leaking blood compressing the brain.
