Cerebral Vascular Accident Stroke
Stroke is a loss of neurological function caused by interruption of blood flow to the brain. To be classified as a stroke, symptoms must be present for at least 24 hours. Symptoms include impairments of sensory, motor, cognitive, perceptual, and language functions. Early detection and treatment are essential to limited long-term complications.
EFFECTS OF STROKE
TYPES OF STROKE
- Ischemic stroke (Most common type) Results from a clot blocking or impaired blood flow which results in deprivation of oxygen and nutrients to the brain
- Hemorrhagic stroke: occurs when blood vessels rupture. It causes blood to leak in or around the brain
EARLY WARNING SIGNS OF STROKE
- Sudden numbness on one side of the body
- Sudden confusion
- Sudden trouble sleeping
- Sudden trouble walking
- Sudden severe headaches
- Heart disease
- Stroke risk is increased 4-6 times in patients with HTN above 160/95 mm Hg
- Increased with elevated total cholesterol and low-density lipoprotein (LDL) cholesterol and decreased with higher levels of high density lipoprotein (HDL)
- Atrial fibrillation is an independent risk factor
- Transient ischemic attack (TIA): 10% of these individuals will have a major stroke within 90 days and 5% within 2 days
Strokes are preventable and listed below are behaviors that can be changed in order to reduce your chances of having a stroke.
MODIFIABLE RISK FACTORS
- Lack of exercise
- Diet: control of cholesterol and lipids
- Excessive alcohol consumption
In some cases, people are predisposed to having strokes because of factors that are out of our control. Below is a list of things that are inherent and thus non-modifiable as it relates to the risks associated with strokes.
NON-MODIFIABLE RISK FACTORS
- Family history
DETECTION OF STROKE
Computed tomography (CT) is used to differentiate between ischemic stroke and hemorrhagic stroke.
