the second mechanism of damage in a hemorrhagic stroke is: Blood spilling out into the __ where it __ ___ ___ causes damage

brain tissue / does not belong

what is an embolus

A mass traveling through the circulatory system that lodges in a blood vessel in the brain (a piece of it breaks off and travels)

hemorrhagic strokes usually occurs in those who

Have high blood pressure; Are engaged in high periods of physical activity; Have a history of hemorrhagic stroke; Experience alcohol abuse

an aneurysm can cause a

hemorrhagic stroke

20, six to eight

Intracerebral Hemorrhage occurs when

A blood vessel bursts within the brain itself

an ischemic stroke occurs when

A blood vessel in the brain is occluded (blood not getting into the brain because it is stopped)

**a hemorrhagic stroke occurs when

A blood vessel within the brain ruptures (blood vessel bursts); Blood spills into the brain; Deprives a part of the brain of blood flow

Thrombotic Stroke occurs when

A thrombus forms and Interrupts blood flow within the brain

what's a neoplasm

Common for children ages 4 years and under to sustain a TBI

the first mechanism of damage in a hemorrhagic stroke is: __ __ to a portion of the brain has been interrupted due to a __ ___ __

Blood supply /burst/broken blood vessel

Three mechanisms of damage may occur in hemorrhagic strokes

Blood supply to a portion of the brain has been interrupted due to a burst/broken blood vessel; Blood spilling out into the brain tissue where it does not belong causes damage; Intracranial pressure increases due to the continued release of blood into the brain or between the surface of the brain and the cranium

a stroke occurs when

Brain tissue is permanently destroyed or temporarily does not function due to decreased or absent blood supply to affected brain tissue

a primary tumor is

aneurysm is due to

Disease or hereditary factors; Hypertension and atherosclerosis

do transient ischemic attack cause permanent damage

Does not cause permanent deficits unless TIAs are recurring

an embolic stroke occurs when
