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.
Stroke symptoms typically start suddenly, over seconds to minutes, and in most cases do not progress further. The symptoms depend on the area of the brain affected. The more extensive the area of the brain affected, the more functions that are likely to be lost. Some forms of stroke can cause additional symptoms.
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 .

A head and neck CT angiogram can be performed within 6 hours of onset of symptoms to see where the occlusion may be located which can help in determining the cause of the stroke. [30] In people who die from a stroke an autopsy can reveal additional diseases or conditions beyond the stroke itself, as well as uncover uncommon causes of a stroke. [31]

Possible secondary causes of cerebral vasculitis are infections such as with varicella zoster virus (chicken pox or shingles), systemic auto-immune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, medications and drugs (amphetamine, cocaine and heroin), some forms of cancer (lymphomas, leukemia and lung cancer) and ...
All symptoms normally resolve within three weeks, and may only last days. [1] Permanent deficits are seen in a minority of patients, ranging from under 10% to 20% in various studies. [1] Less than 5% of patients experience progressive vasoconstriction, which can lead to stroke, progressive cerebral edema, or even death. [1]
Posterior circulation infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.. Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
