Stroke: Warning Signs to Watch for

ADVERTISEMENT

Strokes are a serious medical emergency, claiming countless lives each year. They occur when a blood clot blocks or ruptures a blood vessel in the brain, depriving cells of oxygen and nutrients, leading to tissue damage and potentially fatal consequences. Recognizing warning signs, some of which may appear up to a month before a stroke, is crucial for seeking immediate medical attention.

Types of Strokes There are two main types of strokes:

Ischemic Stroke: This type accounts for about 85% of all stroke cases and is caused by a blockage in an artery supplying blood to the brain. It can result from either cerebral thrombosis (blockage due to plaque buildup) or cerebral embolism (blockage due to a blood clot traveling to the brain).
Hemorrhagic Stroke: This type, accounting for about 15% of stroke cases, occurs when a weakened blood vessel ruptures, leading to bleeding in the brain. Causes include aneurysm rupture, hypertension, tumors, and other bleeding disorders.
Transient Ischemic Attack (TIA) While not technically a stroke, TIAs can mimic stroke symptoms and serve as warning signs. TIAs occur when the blockage causing stroke-like symptoms resolves on its own without causing permanent damage. However, they still warrant immediate medical attention due to the risk of a subsequent stroke.

Warning Signs of Stroke It’s essential to be aware of warning signs that may indicate an impending stroke, including:
