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]
[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 ...
A transient ischemic attack (TIA), commonly known as a mini-stroke, is a temporary (transient) stroke with noticeable symptoms that end within 24 hours. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language or slurred speech.
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]
[2] [3] Signs and symptoms often appear soon after the stroke has occurred. [3] If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke.

This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. [4]
According to the 'time-is-brain' concept in acute stroke, recanalization of the obstructed blood vessels has to be performed within the very first hours after symptom onset. However, patients mostly come too late to the hospital and, therefore, only a minority of patients (5–10%) obtains the time-sensitive recanalizing treatments, and if so ...
