The brain parenchyma is the functional tissue in the brain. It comprises two types of cells explicitly used for cognition, which control the rest of the body. The remaining brain tissue is called the stroma, the supporting tissue. Damage or trauma to the brain parenchyma often leads to a loss of cognitive ability or even death.
Most common causes of brain parenchyma
– Intracerebral hemorrhage (cerebral hemorrhage) is a significant cause of stroke, especially in Asians and black people. Hypertension and trauma cause most of these hemorrhages.
– Hypertensive parenchymal hemorrhage (hypertensive hemorrhage or hypertensive intracerebral bleeding) is usually the result of the spontaneous rupture of a small artery that penetrates deep into the brain.
– Cerebral amyloid angiopathy is a disease of the elderly in which arteriolar and amyloid degeneration occurs deposited on the walls of the cerebral arteries but not elsewhere.
– Cocaine-induced stroke is a significant cause of stroke, especially in patients older than 40 years.
Intracranial hemorrhages associated with anticoagulant therapy can occur anywhere, often lobular or subdural.
– Hemorrhage in a brain tumor may be the first manifestation of the neoplasm.
