[48] [51] [52] MSC treatment also appears to improve the control of cerebral blood flow and blood–brain barrier permeability, [53] [54] as well as what is currently thought to be the most important mechanism of MSC treatment after stroke, the activation of endogenous neuroprotection and neurorestoration pathways by the release of cytokines ...
Cerebral softening, also known as encephalomalacia, is a localized softening of the substance of the brain, due to bleeding or inflammation. Three varieties, distinguished by their color and representing different stages of the disease progress, are known respectively as red, yellow, and white softening.
In the brain, hypertensive encephalopathy - characterized by hypertension, altered mental status, and swelling of the optic disc - is a manifestation of the dysfunction of cerebral autoregulation. Cerebral autoregulation is the ability of the blood vessels in the brain to maintain a constant blood flow. People with chronic hypertension can ...
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.
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [3] [4] [1] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).
Currently there are two treatment options for securing intracranial aneurysms: surgical clipping or endovascular coiling. If possible, either surgical clipping or endovascular coiling is typically performed within the first 24 hours after bleeding to occlude the ruptured aneurysm and reduce the risk of recurrent hemorrhage.

Sharon Stone: Actress slams 'ignorant, arrogant' Americans after Donald Trump win An artery rupture resulting in a brain bleed and stroke left Stone with a 1% survival rate.
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
