Stroke Symptoms and Warning Signs

Stroke is a medical emergency that requires immediate medical treatment, because it often appears suddenly without warning.

By recognizing the warning signs and symptoms of stroke can really help you to decide when to seek medical attention and prevent you or your loved one from a lifetime of brain damage or even death.

Symptoms of stroke depend on the type of stroke and which area of the brain is affected but they usually begin suddenly. The common signs and symptoms of stroke include:

  • Dizziness, difficulty walking or loss of balance
  • Difficulty swallowing or dysphagia
  • Mental impairment process including difficulty speaking, learning, remembering, making decisions, and planning
  • Numbness, paralysis, or weakness, usually on one side of the body
  • Seizure (relatively rare)
  • Severe headache with no known cause
  • Sudden confusion
  • Sudden decrease in level of consciousness
  • Sudden vision problems (e.g. blurred vision, blindness in one eye)
  • Vomiting

If you or someone you know experiences any warning signs or symptoms of stroke described above, seek medical help immediately even if you think that you are getting better or the symptoms seem to disappear. If the symptoms occur frequently or seem to get worse, call 911 and have paramedics come to you.
