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.
Other symptoms include difficulty speaking, slurred speech, and the loss of coordination. [8] The symptoms of brain ischemia range from mild to severe. Further, symptoms can last from a few seconds to a few minutes or extended periods of time. If the brain becomes damaged irreversibly and infarction occurs, the symptoms may be permanent. [9]
Perinatal stroke is a disease where an infant has a stroke between the 140th day of the gestation period and the 28th postpartum day, [1] affecting up to 1 in 2300 live births. [2] This disease is further divided into three subgroups, namely neonatal arterial ischemic stroke, neonatal cerebral sinovenous ischemic stroke, and presumed perinatal ...
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. [3] Hemorrhagic stroke may also be associated with a severe headache. [3] The symptoms of stroke can be permanent. [5]
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]
An ischemic stroke's main cause is atherosclerosis. [2] Stroke is commonly caused by atherosclerotic large vessel disease and results from local branch occlusion by plaque, artery-to-artery embolism, or in situ thrombosis, with the latter being the most common cause of anterior cerebral artery infarction. [4]
Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia , cerebral infarction ...
