8 Warning Signs of Stroke One Month Before + 9 Powerful Tips to Prevent It

2. Sudden Changes in Vision

Blurred sight, double vision, or brief loss of vision in one or both eyes may come and go. This happens when blood supply to the visual areas of the brain flickers. Many people describe it as “like a curtain falling” or just needing to rub their eyes more often—easy to dismiss until it repeats.

3. Intermittent Numbness or Weakness (Especially on One Side)

One of the most common early clues is a tingling, heavy, or numb feeling in the face, arm, leg, or foot that lasts minutes to hours and then fades. You might notice it most when trying to grip things or while lying in bed at night. The one-sided nature is a key detail because it often points to the same brain hemisphere being affected.

4. Unexplained Fatigue or Sleep Disturbances

Feeling unusually tired even after a full night’s rest—or waking up with heavy arms and shoulders that don’t want to move—can signal the brain working harder than usual. Some people report dropping things more often or needing extra naps during the day without any change in routine.
