Hypertension is the strongest risk factor associated with intracerebral hemorrhage and long term control of elevated blood pressure has been shown to reduce the incidence of hemorrhage. [7] Cerebral amyloid angiopathy, a disease characterized by deposition of amyloid beta peptides in the walls of the small blood vessels of the brain, leading to ...
Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2] The strongest risk factor for intraparenchymal hemorrhage associated with cerebral amyloid angiopathy is old age, and cerebral amyloid angiopathy is most frequently seen in patients who already have, or will soon be diagnosed with, dementia.

Historically, it described what is now known as a hemorrhagic stroke, typically involving a ruptured blood vessel in the brain; modern medicine typically specifies the anatomical location of the bleeding, such as cerebral apoplexy, ovarian apoplexy, or pituitary apoplexy. [1] [2] [3]
Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]
The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum. [citation needed] As with any aneurysm, once formed they have a tendency to expand and eventually rupture, in keeping with the Law of Laplace. [4] [5]
For example, you may pronounce cot and caught the same, do and dew, or marry and merry. This often happens because of dialect variation (see our articles English phonology and International Phonetic Alphabet chart for English dialects). If this is the case, you will pronounce those symbols the same for other words as well. [1]
Research is still needed in the area of cerebellar stroke management; however, several factors may lead to poor outcomes in individuals who have a cerebellar stroke. These factors include: Declining levels of consciousness; New signs of brainstem involvement; Progressing Hydrocephalus; Stroke to the midline of the cerebellum (a.k.a. the vermis) [4]
Intraventricular hemorrhage, or bleeding within the ventricles of the brain, leads to hydrocephalus in 51-89% of patients. [30] This is because the blood in the ventricles blocks the regular flow of CSF, leading to build-up of excess CSF [30] Spontaneous intracerebral and intraventricular hemorrhage with hydrocephalus shown on CT scan [31]
