Does meningitis cause seizure?

A seizure may involve shaking, stiffening, staring, loss of awareness, unusual movements or a period of confusion afterwards. In meningitis, infection and inflammation around the brain can interfere with normal electrical activity. Fever may also contribute, particularly in children, but a seizure with suspected infection still needs medical assessment.

Seizures have many causes, including epilepsy, low blood sugar, head injury and other illnesses. A seizure does not identify meningitis by itself. Doctors consider accompanying fever, headache, neck stiffness, light sensitivity, vomiting, rash and changes in alertness.

Protect the person from nearby objects, cushion the head, remove glasses and note how long the episode lasts. When the movements stop, place the person on their side if they are breathing and stay with them. Do not restrain them, put anything in their mouth or offer food and drink until fully alert.

Call emergency services immediately when a seizure is prolonged, repeats without recovery, causes injury, affects breathing, occurs in water or happens to someone with fever, severe headache, neck stiffness or confusion.

Any first seizure needs urgent medical review. Emergency help is especially important when meningitis is possible, because assessment may require hospital monitoring, tests and prompt treatment. Also seek immediate help for a new rash, difficulty waking, collapse or worsening symptoms.

Ask what may have triggered the seizure, whether infection tests or brain monitoring are needed, what recovery symptoms are expected, and what safety plan to follow if another episode occurs.
