Stroke Flashcards
Hemorrhagic Stroke
Ruptured Blood vessel due to weakened or diseased blood vessels
Arterial-venous malformation
Ischemic Stroke
Obstructed blood flow to an area of the brain
Thrombosis or embolism
87% of all strokes
Stats of stroke
800,000 people in the US have a stroke every year 3/4 are first time strokes every 4 min, someones dies of a stroke more common in women (live longer) African americans more common 6.4 per 100,000 children each year
Atherosclerotic stroke
plaque build up> thrombosis> stops blood supply> ischemia ( lack of oxygen)> necrosis
Thrombosis
blood clot from (collagen, platelet aggregation, and thrombus release
necrosis
death of tissue
Cardiogenic stroke
Blood clot (embolism) from aorta to cerebal circulation causes A fib and valvular heart disease
Common Artery for stroke
middle cerebral, common carotid artery
Common places for cardiac thrombosis
ball thrombus in the atria
Right brain stroke complications
paralysis on the left side of the body,
vision problems,
quick, inquisitive behavior, memory loss
Left brain stroke complications
Paralysis on the right side of the body, speech/language problems, slow cautious behavior, memory loss
Neurological Problems associated with stroke
Chronic fait and balance deficit Fall risk Hyperreflexia, spasticity Coordination difficulties Pathological reflexes that change the base of support of the ankle
Neuropsychological/psychosocial problems
Cognitive deficits, executive dysfuction, communication difficulties, poor self efficacy
Exercise response in stroke patients
Overall functional capacity typically low
Peak oxygen uptake is decreased (50% below, energy costs of walking are elevated 1.5 to 2 fold due to abnormal biomechanics)
Higher submax HR (less aerobic quality and energy inefficiency
Effect of exercise training
increase aerobic capacity
improve cardiovascular disease risk
greater glucose tolerance
higher brain blood flow and brain function
greater muscle function (strength and endurance)
better mobility
better bone health
