tudies show that timely intervention after early symptoms can prevent a high percentage of future strokes.

Final Takeaway
Most strokes are sudden, but many cases are preceded by warning signs — sometimes days, weeks, or even months before the major event. A transient ischemic attack (TIA), unusual or severe headaches, and subtle neurological changes are all examples of early warning signs that should never be ignored. If you or someone you know experiences any of these symptoms, seek medical evaluation immediately — acting early can save lives and reduce long‑term disability.
