What is a stroke?
A stroke, also known as a cerebrovascular accident or brain attack, occurs when the brain’s blood supply is interrupted, causing brain cells to die. The types of strokes are:
- Ischemic stroke (clots): This is the most common type. Ischemic stroke occurs when blood vessels in the brain are blocked by blood clots, leading to a loss of blood flow to brain tissue.
- Hemorrhagic stroke (bleeds): This happens when a weakened blood vessel bursts, causing bleeding in the brain, often due to high blood pressure.
- Transient ischemic attack (TIA): Known as a "mini-stroke," this is a temporary blockage of blood flow, serving as a warning for future strokes.
- Cryptogenic stroke: A stroke with no identifiable cause, often linked to undetected blood clots.
- Brain stem stroke: Affects the brain stem, potentially leading to severe disabilities, including a “locked-in” state.
Understanding stroke prevention and managing blood pressure are key components in reducing stroke risk.
