A stroke, often referred to as a brain attack, occurs when blood flow to a part of the brain is blocked or when a blood vessel in the brain ruptures. When brain cells are deprived of oxygen, they begin to die within minutes, leading to potential long-term disability, brain damage, or even death.
Certain medical conditions and lifestyle choices can increase the risk of stroke. Recognizing the warning signs and seeking immediate medical care can significantly improve outcomes.
What Happens During a Stroke?
The brain is responsible for movement, memory, emotions, and essential bodily functions such as breathing and digestion. It relies on oxygen-rich blood supplied by arteries. When blood flow is interrupted, brain cells die even briefly, resulting in serious consequences.
A stroke can happen suddenly and requires urgent attention. The faster treatment is administered, the better the chances of minimizing long-term effects.
Why Quick Treatment Is Critical
A stroke is a medical emergency that demands immediate action. If you or someone around you experiences stroke symptoms, act F.A.S.T. and call 9-1-1 immediately.
Face – Does one side of the face droop?
Arms – Can the person raise both arms or is one weak?
Speech – Is speech slurred or difficult to understand?
Time – Every second counts. Call emergency services without delay.
Seeking medical attention at the first sign of a stroke can prevent further brain damage and increase the chances of recovery.
Types of Stroke
There are two main types of stroke, along with a warning event known as a transient ischemic attack (TIA), sometimes called a "mini-stroke."
Ischemic Stroke
The most common type, ischemic stroke, happens when a blood clot or fatty plaque blocks blood vessels leading to the brain. Restricted blood flow prevents oxygen from reaching brain cells, causing them to die.
Hemorrhagic Stroke
A hemorrhagic stroke occurs when a weakened blood vessel in the brain leaks or bursts, leading to bleeding in the brain. This excess pressure damages brain cells and can be life-threatening. High blood pressure and aneurysms – bulging arteries that may rupture – are major risk factors.
Transient Ischemic Attack (TIA)
Also known as a "mini-stroke," a TIA happens when blood flow to the brain is temporarily blocked, usually for no more than five minutes. While symptoms may disappear quickly, TIAs are severe warning signs of a potential major stroke.
Key facts about TIAs:
A TIA indicates a higher risk of future strokes.
It should always be treated as a medical emergency.
More than a third of people who experience a TIA and don’t receive treatment have a major stroke within a year.
Timely medical intervention can reduce the likelihood of a severe stroke.
Recognizing and Preventing Stroke
Understanding the symptoms and risk factors for stroke is essential for prevention. High blood pressure, high cholesterol, smoking, obesity, and an inactive lifestyle increase the likelihood of experiencing a stroke. Managing these risks through regular medical checkups, healthy eating, and physical activity can help prevent strokes.
