Seizure in medical terms: what it means

A seizure may involve stiffening, rhythmic jerking, staring, brief loss of awareness, unusual smells or feelings, or temporary confusion. Some seizures are subtle and may look like repeated blinking or a pause in responding. A single seizure does not automatically mean epilepsy; clinicians consider the circumstances, examination, and whether episodes recur.

Possible triggers or causes include low blood glucose, infection affecting the brain, head injury, alcohol withdrawal, or another neurological problem. Hypoglycaemia, meningitis, and Alcohol Use Disorder are examples of conditions a clinician may consider when the history fits.

Move nearby hard or sharp objects away, cushion the head, loosen tight clothing around the neck, and note when the episode starts. Do not restrain the person and do not put food, drink, or objects in the mouth. When the movements stop, place the person on their side if they are breathing and stay with them until awareness returns.

Call emergency services if this is a first seizure, the episode lasts longer than expected, seizures repeat without full recovery, breathing remains difficult, a serious injury occurs, or the person is pregnant, has diabetes, or does not regain normal awareness. Seek prompt assessment after any unexplained seizure, even if the person appears well afterward.

Ask what type of episode is suspected, whether blood tests or brain tests are needed, which warning signs require emergency help, and whether driving, bathing alone, swimming, or work activities should be restricted while the cause is being assessed.
