virulent means
strength or ability of pathogen to produce disease
Which of the following conditions would MOST likely mimic the signs and symptoms of an acute ischemic stroke?
hypoglycemia
Migraine headaches are thought to be caused by:
changes in blood vessel size within the base of the brain.
what does Lamictal and dilantin treat
seizures
what does SARS look like and do
SARS is caused by a virus and usually starts with flulike symptoms that deteriorate to pneumonia and respiratory failure.
Index of suspicion is MOST accurately defined as:
your awareness and concern for potentially serious underlying and unseen injuries or illness.
________________ is a disorder of the brain in which blood flow to a portion of the brain is suddenly disrupted, resulting in brain cell death.
Cerebral infarction
A degenerative cerebral disease is an example of a(n) ______________ cause of a seizure.

5-45 days
central nervous system is responsible for
thought perception feeling and autonomic body functions
peripheral nervous system is responsible for
transmits commands from the brain to the body and receives feedback from the body
3 major parts of brain and what they primarily do
cerebrum- right and left hemisphere - controls opposite side of body
- front of cerebrum- emotion and thought - middle - touch and movement - back- sight - left side- speech
cerebellum- muscle and body function
brain stem- basic function control- breathing , BP, swallow , pupil constriction
12 cranial nerves running directly to
parts of the head
complex activity in the brain is made possible by
synapses
present wherever a cell terminates and “connects” to next cell via chemical neurotransmitters
following a stroke , dead cells are called
infarcted cells
interruption of cerebral blood flow may result because of -3
thrombus- clot developed locally
arterial rupture
cerebral embolism - clot from somewhere else
two main types of strokes
ischemic and hemorrhagic ( arterial rupture )
patients are at higher risk for hemorrhagic stroke who have ___
poorly managed hypertension
what is an aneurysm
common signs-2
enlargement of artery due to weak wall
“worst headache “ or rapid LOC change ( ICP)
when a hemorrhagic stroke occurs in a healthy person its called
berry aneurysm - subarachnoid hemorrhage - bizarre vital signs
