Stroke Information - symptom, cause, sign, treatment of
In the United States, stroke remains the third leading cause of death, despite a general decline in the incidence of stroke in the last 30 years. The precise reasons for this decline are uncertain, but increased awareness of risk factors (hypertension, diabetes, hyperlipidemia, cigarette smoking, cardiac disease, AIDS, recreational drug abuse, heavy alcohol consumption, family history of stroke) and improved prophylactic measures and surveillance of those at increased risk have been contributory. Elevation of the blood homocysteine level is also a risk factor for stroke, but it is unclear whether this risk is reduced by treatment to lower the level. A previous stroke makes individual patients more susceptible to further strokes.
For years, strokes have been subdivided pathologically into infarcts (thrombotic or embolic) and hemorrhages, and clinical criteria for distinguishing between these possibilities have been emphasized. However, it is often difficult to determine on clinical grounds the pathologic basis for stroke
Symptoms and Signs of Stroke
