Having stroke in the past greatly increases one's risk of future stroke. Men are 25% more likely to develop stroke than women, [53] yet 60% of deaths from stroke occur in women. [233] Since women live longer, they are older on average when they have stroke and thus more often killed. [53] Some risk factors for stroke apply only to women.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. [5]
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
[3] [4] [1] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other). [3] [4] Symptoms can vary dramatically depending on the severity (how much blood), acuity (over what timeframe), and location (anatomically) but can include headache, one-sided weakness, numbness, tingling, or paralysis, speech ...
Other symptoms can include numbness in the face, arm, or leg, particularly if it’s one side of the body, confusion, trouble seeing, trouble walking, and a severe headache with no known cause.

Focal injuries typically have symptoms that are related to the damaged area of the brain. [3] Stroke can produce focal damage that is associated with signs and symptoms that correspond to the part of the brain that was damaged. [1] For example, if a speech center of the brain such as Broca's area is damaged, problems with speech are common.
