Stroke Flashcards
Stroke
occurs when there is ischemia to a part of the brain that results in brain cells
Stroke precursor
coronary artery disease
Factors effecting blood flow to brain
systemic BP
cardiac output
blood viscosity
Collateral Circulation
another way that the body compensates or manages risk factors
more than one way for the brain to be perfused
Risk factors of Stroke
Non-modifiable
- age (>65)
- gender (male)
- race
- family hx
Modifiable
- smoking
- alcohol
- obesity
- inactivity
- high cholesterol
- oral contraceptives
Contributing factors of stroke
HTN!!!!
Diabetes, Heart disease
Crushing triad
What stroke causes
Increased SBP
Decreased P
Decreased RR
Ischemic strokes
TIA
Thrombotic
Embolic
Hemorrhagic strokes
Intracerebral
Subarachnoid
Transient Ischemic Attack (TIA)
precursor to ischemic stroke
temporary loss of neuro function
caused by microemboli
Thrombotic
narrowing of artery by plaque that blocks the passage of blood
symptoms slow
Embolic
Blood clot or other debris circulating in blood and then lodges
symptoms are sudden
Intracerebral
occurs during activity
HTN risk factor
sudden onset with progressive symptoms b/c of bleeding
Subarachnoid
intracranial bleeding into CSF space
rupture of cerebral aneurysm
Manifestations of stroke
Motor function (akinesia/swallowing)
Affect (emotions)
Spatial receptable alteration (agnosia apraxia)
Elimination
