Bell's Palsy vs Stroke: Your Forehead Holds the Most Important Clue
The single most useful distinction between Bell's palsy and stroke comes down to your forehead. Bell's palsy paralyzes the entire side of the face, forehead included, so you can't wrinkle that side or fully close the eye. Stroke typically spares the forehead, affecting mainly the lower face around the mouth. That one detail matters enormously because these two conditions need completely different treatments on completely different timelines. Bell's palsy calls for early steroids. Stroke is a time-sensitive emergency. Getting the wrong one can mean getting the wrong care.
