CVA Review

TIA is also called a

"mini stroke", "silent stroke" or a reversible ischemic neurological deficit

TIA

- temporary episode of neurologic dysfunction manifested by sudden loss of motor, sensory, or visual function

Predisposing risk factors for a TIA and possible stroke

-History of tobacco use for 25 years -Husband smokes one pack per day -Sedentary lifestyle/ Physical inactivity -High total cholesterol; low HDL cholesterol. Normal values (Total cholesterol < 200, HDLs 40mg/dL or higher, LDL less than 100mg/ dL). -Ethnicity (African American). -Heredity (Positive family history of heart disease). -Gender -Stroke is more common in men than women, however women account for more than half of all stroke-related deaths. -Age (59 years old). Increased age increases risk of stroke in men 45 years or older and in women 55 years or older

is that a TIA involves a short duration of interrupted blood flow to an area of the brain and does not usually result in permanent deficits

a (reduces intercranial pressure due to straining)

Ataxia
