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.
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]
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body. Either hemiparesis or hemiplegia can result from a variety of medical causes, including congenital conditions, trauma, tumors, traumatic brain injury and stroke. [1]
Symptoms depend on the type of stroke and what part of the brain is being affected. According to Dr. Ince and the CDC, common signs include: Sudden weakness or numbness on one side of the body and ...
These localizing signs and symptoms can include hemiplegia (or weakness localized to one side of the body) and paresthesia (loss of sensation) including hemisensory loss (if localized to one side of the body). [7] These symptoms are usually rapid in onset, sometimes occurring in minutes, but not as rapid as the symptom onset in ischemic stroke. [7]
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.
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.
