Stroke is a medical emergency that can change lives in a matter of seconds. It is one of the leading causes of death and long-term disability worldwide, according to health organizations. Recognizing the early warning signs is critical: the faster you act, the greater the chances of recovery and reduced complications.
Eight Warning Symptoms of a Stroke
1. Numbness or Weakness on One Side of the Body
A sudden loss of strength or numbness—often in the face, arm, or leg, typically on one side of the body—is one of the most common signs. If a raised arm drops quickly or a leg drags while walking, it’s a red flag that requires urgent attention.
2. Difficulty Speaking or Understanding
Slurred speech, trouble forming words, or difficulty understanding others may indicate a stroke. The person may appear confused, disoriented, or unable to repeat simple phrases.
3. Vision Problems
Sudden blurred vision, double vision, or partial/complete loss of vision in one or both eyes should never be ignored.
4. Sudden and Severe Headache
An intense headache with no clear cause is a classic warning sign, especially in younger individuals without a prior history of headaches.
5. Dizziness or Loss of Balance
Stroke can cause sudden dizziness, difficulty walking, or loss of coordination, often accompanied by disorientation.
6. Nausea and Vomiting
Although less common, these symptoms can occur suddenly, especially when combined with other warning signs.
7. Sudden Changes in Behavior
Episodes of unusual sleepiness, agitation, or sudden lack of energy may indicate changes in brain function.
