A silent lacunar infarction (SLI) is one type of silent stroke which usually shows no identifiable outward symptoms, and is thus termed "silent". Because stroke is a clinical diagnosis (that is, it is defined by clinical symptoms), there is debate about whether SLI are considered to be strokes, even though the pathophysiology is presumably the ...
These affect the deep structures of the brain and may leave small (~5mm) cavity lesions. Small lacunar infarcts are "caused by various arterial disorders, the most frequent of which include microatheroma, lipohyalinosis, fibrinoid necrosis, and Charcot-Bouchard aneurysm". [7] Lipohyalinosis was considered the most common cause for lacunar ...
A silent stroke (or asymptomatic cerebral infarction) is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke. Despite not causing identifiable symptoms, a silent stroke still causes damage to the brain and places the patient at increased risk for both ...
A brainstem stroke syndrome falls under the broader category of stroke syndromes, or specific symptoms caused by vascular injury to an area of brain (for example, the lacunar syndromes).
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 ]
Vascular thalamic amnesia occurs when the thalamus is affected by Korsakoff's syndrome or damaged by lacunar infarcts or hemorrhages. [1] Another common cause for damage to the thalamus that may contribute to the development of amnesia is a stroke. [ 2 ]
Charles Miller Fisher (December 5, 1913, Waterloo, Ontario – April 14, 2012, Albany, New York) was a Canadian neurologist whose notable contributions include the first detailed descriptions of lacunar strokes, the identification of transient ischemic attacks as stroke precursors, the identification of the link between carotid atherosclerosis and stroke, and the description of a variant form ...
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [1] 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]
