pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES.

WebMD explains categories of brain disease, including those caused by infection and trauma and those caused by vascular, neurodegenerative, and autoimmune disorders. Brain diseases come in different forms. Infections, trauma, stroke, seizur

About 18% of the total blood volume in the body circulates in the brain, which accounts for about 2% of the body weight. Vascular insult to the brain (cerebrum, cerebellum, or brainstem), commonly referred to as stroke or cerebrovascular accident (CVA), is brain cell death caused by an interruption of blood flow within or leading to the brain, or by a hemorrhage from a ruptured blood vessel or aneurysm in the brain. n a nonprogressive impairment of muscular function and weakness of the limbs, caused by lack of oxygen to the brain immediately after birth, brain injury during birth, or viral infection English Collins Dictionary - English Definition & Thesaurus Cerebral hypoxia is a form of hypoxia, specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia, focal cerebral ischemia, cerebral infarction, and global cerebral ischemia. Prolonged hypoxia induces neuronal cell death via apoptosis, resulting in a hypoxic brain injury. Cases of total oxygen deprivation are A ruptured brain aneurysm is the most common and the most deadly vascular brain abnormality, with a 50 percent fatality rate.

Vascular malformations can also become unstable and rupture, releasing blood into the brain and causing a stroke. When a vascular malformation ruptures, the result is called a hemorrhage.

Ischemic cerebral insult happens when a blood clot or embolus blocks or slows down blood flow in the brain artery, thus blocking transport of oxygen and glucose that are necessary for regular function of the brain. It could be also caused by a spasm of brain arteries, without any obstruction of the arterial flow.

Cerebrovascular insult may be used interchangeably. The term brain attack was introduced for use to underline the acute nature of stroke according to the American Stroke Association, which has used the term since 1990, and is used colloquially to refer to both ischemic as well as hemorrhagic stroke. Research Se hela listan på mayoclinic.org Such compromise is not seen in adult brain tissue (Laursen et al., 1986; Gillinov et al., 1992; Waaben et al., 1994), suggesting an enhanced vulnerability to insults in the developing brain. Most current research into perinatal NVU pathology has examined insults falling within three broad pathological processes: prematurity, acute hypoxia, and chronic hypoxia ( Figure 2 ).

Most prevalent causes of brain lesions are mentioned below: Stroke, vascular injury or impaired supply of blood to the brain is perhaps the leading cause of lesions on the brain. These vascular events might be secondary to conditions like hypertension and atherosclerosis. Vascular dementia is characterized by a subtle and progressive worsening of memory that occurs in a stepwise fashion due to strokes occurring within the brain. Deficits may begin suddenly and then remain stable during a plateau period before more insults to the brain occur. 2006-01-23 · We present a method to produce vascular disruptions within rat brain parenchyma that targets single microvessels.

The insult is thus differentiated from global ischemia in two very important ways.
