6. Sudden Severe Headache with No Known Cause
Sudden, severe headache with no apparent reason can be a sign of stroke. Certain strokes cause arteries to burst in the brain, causing bleeding and generating pressure on the brain. The headache results from the rupturing of blood vessels. Wherever the headache pain is can indicate where the stroke is happening in the brain.
7. Sudden Confusion or Trouble Understanding
Experiencing sudden confusion while having a stroke occurs when a stroke affects areas of the brain important to reasoning and judgment. Depending on how severe the stroke is, the cognitive process can be severely impacted due to brain damage. Vascular dementia results from no blood flow or decreased flow to the brain and can be a long-term symptom.
