Stroke
Definition:
A medical emergency that occurs when blood flow to a part of the brain is interrupted, leading to brain cell damage.
Types:
Ischemic Stroke: Caused by a blockage in a blood vessel (e.g., a blood clot).
Hemorrhagic Stroke: Caused by bleeding in or around the brain, often due to a ruptured blood vessel.
Risk Factors:
High blood pressure, diabetes, smoking, high cholesterol, obesity, and a sedentary lifestyle.
Family history and certain heart conditions.
Symptoms:
Sudden numbness or weakness (especially on one side of the body).
Confusion, trouble speaking or understanding.
Vision problems, dizziness, or loss of balance.
Diagnosis:
Neurological examination and imaging tests (CT scan, MRI) to determine the type and location of the stroke.
Treatment Options:
Ischemic Stroke: Clot-busting medications (thrombolytics) and sometimes mechanical thrombectomy.
Hemorrhagic Stroke: Surgical intervention to repair blood vessels or relieve pressure.
Rehabilitation:
Focus on physical, occupational, and speech therapy to regain lost functions and improve quality of life.
Prevention:
Lifestyle changes: healthy diet, regular exercise, managing chronic conditions, and avoiding smoking.
