A stroke is one of the leading causes of death and long-term disability worldwide. It occurs when blood flow to part of the brain is interrupted or when a blood vessel in the brain ruptures, preventing brain cells from receiving the oxygen and nutrients they need.
You’ve probably seen headlines claiming that “your body warns you a month before a stroke.” While it’s true that some people experience warning symptoms before a stroke, there is no reliable evidence that everyone receives warning signs weeks or a month in advance. In many cases, a stroke happens suddenly without any noticeable symptoms beforehand.
However, some people experience a transient ischemic attack (TIA)—often called a “mini-stroke”—days or weeks before a major stroke. A TIA is a medical emergency and should never be ignored, even if symptoms disappear within minutes.
Here are 10 warning signs that require prompt medical attention.
1. Sudden Weakness or Numbness
One of the most common warning signs is sudden weakness, numbness, or tingling, especially on one side of the body.
You may notice weakness in your:
- Face
- Arm
- Hand
- Leg
If one side of your face droops when you smile or one arm drifts downward when raised, seek emergency medical care immediately.
2. Difficulty Speaking
A stroke can affect the parts of the brain responsible for language.
Warning signs include:
- Slurred speech
- Difficulty finding words
- Trouble understanding what others are saying
- Speaking in confused or nonsensical sentences
Even if these symptoms last only a few minutes, they should never be ignored.
