Understanding Stroke
Definition of Stroke
A stroke occurs when the blood supply to a part of the brain is interrupted or reduced, leading to the death of brain cells. It is a medical emergency that can cause severe disability or even death if not treated promptly. Strokes can be classified into two main types: ischemic stroke and hemorrhagic stroke.
Types of Stroke
-
Ischemic Stroke: This is the most common type of stroke, accounting for about 80% of all cases. It occurs when a blood clot blocks a blood vessel in the brain, preventing blood flow to that area.
-
Hemorrhagic Stroke: This type of stroke happens when a blood vessel bursts, causing bleeding in the brain. It can occur due to high blood pressure, trauma, or abnormalities in the blood vessels.
Prevalence of Stroke in Malaysia
Stroke is a major health concern in Malaysia, with an estimated 52,000 cases reported annually. It is the third leading cause of death in the country, and the leading cause of adult disability. The prevalence of stroke in Malaysia is influenced by various factors such as an aging population, unhealthy lifestyles, and the high prevalence of risk factors like hypertension and diabetes.
