A stroke is a critical medical emergency that occurs when blood flow to the brain is interrupted. While many assume strokes happen suddenly, the body often gives warning signs weeks or even months in advance.
Research indicates that certain symptoms can appear up to 90 days before a stroke. Identifying these early signs can help you seek medical attention in time and potentially prevent a major stroke.
What Causes a Stroke?
A stroke occurs when blood flow to the brain is obstructed or when a blood vessel bursts, leading to brain cell damage or death. This can result in severe complications such as paralysis, speech difficulties, or even fatal outcomes.
Main Types of Stroke:
- Ischemic Stroke – The most common type, caused by a blood clot blocking blood flow to the brain.
- Hemorrhagic Stroke – Occurs when a blood vessel in the brain bursts, causing bleeding.
- Transient Ischemic Attack (TIA) – Also known as a “mini-stroke,” where blood flow is temporarily blocked but recovers quickly.
Dr. Giglio stressed that just because a TIA doesn’t cause permanent brain damage, it doesn’t mean the symptoms should be ignored.
“It could indicate that you are at risk of having a stroke within the next 48 hours, and certainly within 7, 30, or even 90 days.”
Recognizing Stroke Symptoms: The “BEFAST” Method
Experts recommend using the acronym BEFAST to quickly identify stroke symptoms:
