The brain parenchyma is the functional tissue in the brain. It is composed of two types of cells that are used specifically for cognition, which control the rest of the body. The remaining brain tissue is called the stroma, which is 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 major 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 hemorrhage) 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 major cause of stroke, especially in patients older than 40 years.
– Intracranial hemorrhages associated with anticoagulant therapy can occur anywhere; which are often lobular or subdural.
– Hemorrhage in a brain tumor may be the first manifestation of the neoplasm.
– Hypertensive encephalopathy is a complication of malignant hypertension .
