Pure sensory stroke: contralateral thalamus , internal capsule, corona radiata, midbrain Marked by numbness (loss of sensation) on one side of the body; can later develop tingling, pain, burning, or another unpleasant sensation on one side of the body. Mixed sensorimotor stroke: thalamus and adjacent posterior internal capsule, lateral pons
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]
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
Partial anterior circulation infarct (PACI) is a type of cerebral infarction affecting part of the anterior circulation supplying one side of the brain.. Partial anterior circulation stroke syndrome (PACS) refers to the symptoms of a patient who clinically appears to have had a partial anterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the ...
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.
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 .

And thus it was thought that the pain associated after stroke was part of the stroke and lesion repair process occurring in the brain. [ medical citation needed ] It is now accepted that Dejerine–Roussy syndrome is a condition developed due to lesions interfering with the sensory process, which triggered the start of pharmaceutical and ...
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
