Symptoms of a stroke or transient ischemic attack (TIA) develop quickly and include:

• Sudden numbness, paralysis, or weakness in your face, arm, or leg, especially on only one side of your body.
• New problems with walking or balance.
• Sudden vision changes.
• Drooling or slurred speech.
• New problems speaking or understanding simple statements, or feeling confused.
• A sudden, severe headache that is different from past headaches.

A stroke is an emergency and requires immediate medical attention.
