What are encephalitis symptoms and signs?
The signs and symptoms of encephalitis can range from very mild flu-like symptoms to potentially life-threatening events. Signs and symptoms of encephalitis include sudden fever, headache, vomiting, visual sensitivity to light, stiff neck and back, confusion, drowsiness, unsteady gait, and irritability. Loss of consciousness, poor responsiveness, seizures, muscle weakness, sudden severe dementia, and memory loss can also be found in patients with encephalitis.
Anyone experiencing symptoms of encephalitis should see a doctor immediately.
