Tissue infarction, involving death of essentially all cells within a part of the brain, is a common pathology resulting from stroke and an important determinant of the long-term consequences of this disorder. The cell death that leads to infarct formation is likely to be the result of multiple...
or CT scan, helps to confirm whether an individual is having a stroke, and what type of stroke has occurred. Alternatively, physicians can detect brain tissue damage using Magnetic Resonance
Hemorrhagic (heh-more-raj-ik) strokesoccur when a blood vessel in the brain breaks or ruptures. The result is blood seeping into the brain tissue and damage to brain cells. The most common causes of hemorrhagic stroke are high blood pressure and brain aneurysms. An aneurysm is a weakness ...

Infarction is a well-demarcated tissue lesion and a pH thresholded pan-necrosis, whereas selective neuronal loss is a lesser tissue lesion that clinically manifests most commonly with memory loss due to bilateral hippocampal neuronal loss after global ischemia. Important diseases of the arteriole ...
aA recent study in human stroke brain tissue demonstrated that leukocytic MMP-9 is colocalized with collagen IV proteolysis in basal lamina, which in turn appeared to correspond with areas of MMP-9-positive neutrophil infiltration in infarcted and hemorrhagic areas 正在翻译,请等待...[translate]...
Wound repair astrocytes (in green) form a border around the inflammatory cells (in white) that invade an area of brain tissue damaged by a small stroke. This astrocyte border isolates the inflammatory cells and prevents their migration away from the damaged tissue and thereby protects the nearby...
Brain tissue that borders the infarct. Infarct The site of tissue loss in the brain from a stroke. Dendritic spines Sub-micrometre protrusions on dendrites of a neuron that receive synaptic input as postsynaptic elements in the synaptic connection. Axonal sprouting The growth and extension of a ...
WMH and microhaemorrhages reflect direct tissue damage and neuroimaging studies have consistently demonstrated an association between WMH[16]and microhaemorrhages[18]with cognitive impairment. WMH in stroke patients has been associated with selective atrophy of the hippocampal subfields, namely the subiculu...
