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 ...
2. The intrinsic capability of brain self-repair in stroke recovery 2.1. Spontaneous recovery after stroke Despite the permanent brain tissue damage, spontaneous recovery occurs days, weeks, and months after stroke onset. Spontaneous recovery stands for the intrinsic recovery, which is not caused by...
intracerebral hemorrhage (ICH): bleeding directly into the brain tissue; may cause a stroke.ischemia: a low oxygen state usually due to obstruction of the arterial blood supply or inadequate blood flow leading to hypoxia in the tissue.subarachnoid hemorrhage: bleeding in the space surrounding the ...
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 ...
in the brain. Computerized Tomography, 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 Imaging (MRI), according to theNational Institutes of Health(NIH)....
creates an anti-inflammatory and neuroprotective environment in the brain that mitigates damage following a stroke," explained Dr Kriz, who is a member of the Université Laval's Faculty of Medicine. "It prevents an acute inflammatory response that, if not controlled, is harmful to brain tissue....
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...
Damage from a stroke is visible about midway down this slice of human brain, on the far right. A technique invented at SLAC allows researchers to rapidly scan brain tissue and identify areas where. Credit: Helen Nichol (Medical Xpress) -- A technique SLAC scientists invented for scanning ancie...
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...
