Approximately 10% of these silent strokes are silent lacunar infarctions. While dubbed "silent" due to the immediate lack of classic stroke symptoms, SLIs can cause damage to the surrounding brain tissue and can affect various aspects of a person's mood, personality, and cognitive functioning .
Left sided cerebellar stroke due to occlusion of a vertebral artery. Cerebellar strokes account for only 2-3% of the 600,000 strokes that occur each year in the United States. [3] They are far less common than strokes which occur in the cerebral hemispheres.
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.
Meningitis and infections of the ear, nose and throat area such as mastoiditis and sinusitis; Direct injury to the venous sinuses; Medical procedures in the head and neck area; Obesity, especially in combination with oral contraceptive use [10] Sickle cell anemia; Dehydration, primarily in infants and children; Homocysteinemia; Homocystinuria
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]
[10] Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7] Intracerebral hemorrhage into the cerebellum may cause ataxia, vertigo, incoordination of limbs and vomiting. [7]
