New medical findings suggest that a stroke may not be as sudden as many people believe. According to neurologists, the body can exhibit an early warning signal as far as three months before a major stroke occurs — and recognizing this sign in time could significantly reduce the risk of long-term brain damage.

The subtle symptom most frequently reported is recurrent numbness or weakness on one side of the body, particularly in the arm, leg, or face. Because the sensation is mild and often temporary, many people mistakenly dismiss it as stress, poor circulation, or fatigue, causing critical delays in diagnosis.

Experts explain that this early sign may indicate transient ischemic attacks (TIAs) — brief interruptions of blood flow to the brain. Although TIAs resolve on their own, they serve as a major red flag. Studies show that up to 20–30% of patients who experience a TIA may suffer a full stroke if they do not receive timely medical care.

Doctors advise individuals to seek immediate evaluation if they notice:

• Repeated numbness or tingling on one side of the body

• Sudden imbalance or dizziness

• Temporary difficulty speaking

• Short episodes of blurred or double vision

Early detection and treatment — including blood thinners, blood pressure control, and lifestyle adjustments — can prevent up to 80% of stroke cases.

Healthcare professionals emphasize that no warning sign should be ignored. Identifying subtle neurological symptoms early may be the key to preventing a life-threatening event.
