A Sign of Stroke May Occur 90 Days in Advance
Stroke is one of the leading causes of disability and death worldwide, often striking without warning. However, research shows that the body may give early signals—sometimes up to 90 days before a major stroke occurs. Recognizing these subtle signs could make the difference between prevention and a life-threatening medical emergency.
What Is a Stroke?
A stroke happens when blood flow to the brain is interrupted, either due to a blood clot (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). Without oxygen, brain cells begin to die within minutes, making timely medical intervention critical.
Early Warning Signs That May Appear Months Before
Doctors emphasize that certain transient symptoms can serve as red flags long before a stroke strikes:
Transient Ischemic Attacks (TIAs)
Often called “mini-strokes,” TIAs occur when blood flow to the brain is temporarily blocked. They cause stroke-like symptoms—such as weakness on one side, blurred vision, or trouble speaking—that may last only a few minutes. Although they resolve quickly, TIAs are a major warning that a full stroke may follow within weeks or months.
Frequent Headaches or Dizziness
Unusual headaches, especially when combined with dizziness or vision problems, can indicate restricted blood flow to the brain.
Sudden Numbness or Weakness
Experiencing brief episodes of weakness, tingling, or numbness in the face, arms, or legs may point to underlying circulation issues.
