What should you know about mild seizure?

Seizures result from a temporary burst of abnormal electrical activity in the brain. A person may stare, become unresponsive, jerk one limb, lose muscle tone, or feel an unusual smell or sensation. They may remember little afterwards. Causes include low blood sugar, alcohol withdrawal, fever, head injury, medicines, or epilepsy, but one event does not by itself establish epilepsy. A clinician may need the account of a witness, a physical examination, and selected tests.

Protect the person from nearby hazards, cushion the head, loosen tight clothing, and turn them onto their side once movements stop. Time the event and observe breathing. Do not restrain them, put anything in their mouth, or give food or drink until they are fully alert. Record what happened before, during, and after the episode, including sleep loss, alcohol, illness, or missed medicines. Arrange medical review after a first seizure or any change from a known pattern.

Call emergency services if the seizure lasts longer than expected, repeats without recovery, causes serious injury, happens in water, or the person has trouble breathing or remains unresponsive. Urgent assessment is also needed with a severe headache, stiff neck, fever, pregnancy, diabetes, or suspected poisoning. A seizure linked to low blood sugar or alcohol withdrawal can become dangerous and should not be managed alone.

What tests are appropriate after this event? Could a medicine, alcohol change, sleep loss, or low blood sugar have contributed? When is it safe to drive, work at heights, swim, or bathe alone?
