What type of brain damage is a stroke likely to cause?
Posted by: admin : Category: Stroke
What is the usual type of brain damage that a stroke can cause? Is it likely to lose capacity for thought and problem solving skills? Also, is it possible for tissue damage to restore itself back to the level of functioning it was at before, as the brain regularly restores cells?
Damage and the subsequent problems with speech, language, and cognition rely entirely on the site and size of the lesion.
Tissue does not regenerate significantly enough to affect functional recovery, unfortunately.
Yes, it is entrirely possible to have damaged reasoning and problem-solving skills. Typically, in the absence of a language deficit, the lesion in that case would most likely be in the frontal lobe of the right cerebral hemisphere.

it depends on what side of the brain

It depends on what part of the brain was affected and how soon medical attention was received, as well as the therapy afterwords.
I have worked with patients who have had strokes. Many have made complete recovery, some have some mental impairment,

A stroke causes a type of brain damage called Infarction.
Infarction occurs when an area of the brain experiences local tissue death, and in the case of stroke this happens due to lack of blood supply. Infarction can occur in all areas of the brain, including the cerebral hemispheres, thalami, basal ganglia, brain stem, or cerebellum.
Causes of Infarction
The most common cause of brain infarction is stroke, which is when blood supply to the brain is interrupted. A ischemic stroke occurs when a blood vessel carrying blood to the brain is blocked by a blood clot. A hemmorhagic stroke occurs when a blood vessel breaks open, causing blood to leak into the brain. The risk of stroke increases with high blood pressure, age, family history, smoking, heart disease, diabetes, and high cholesterol.
Symptoms of Infarction
* Symptoms of infarction include:
* Weakness, numbness, tingling, or decreased sensation of any body part
* Slurred speech or difficulty speaking; swallowing difficulties and drooling
* Vision changes
* Memory loss
* Loss of coordination and balance; dizziness
* Personality and emotional changes
* Drowsiness and lethargy
* Uncontrollable eye movements or drooping of the eyelids
Prognosis of Infarction
Depending upon the severity of the infarction, degree of recovery, as well as how long it takes to recover, varies from person to person. Rehabilitation often consists of physical therapy, occupational therapy, speech therapy, or a combination of the three.
