What should you know about gtc seizure?

Some seizures cause stiffening and rhythmic jerking, while others involve staring, loss of awareness, unusual sensations, brief confusion, or repetitive movements. A single seizure does not by itself establish epilepsy. Possible triggers include low blood sugar, alcohol withdrawal, infection affecting the brain, head injury, sleep loss, or an underlying neurological condition. A clinician will consider what happened before, during, and after the episode.

Protect the person from nearby hazards, cushion their head, loosen tight clothing around the neck, and time the event. When movements stop, turn them onto their side and stay with them while awareness returns. Do not restrain them, place anything in their mouth, or give food, drink, or medicine until they are fully alert. Note unusual movements, breathing changes, injury, and recovery time for the clinician.

Call emergency services if the seizure lasts longer than expected, repeats without recovery, causes a serious injury, occurs in water, or breathing does not return normally. Urgent assessment is also needed for a first seizure, pregnancy, diabetes, or a new severe headache, fever, stiff neck, or confusion. These features can occur with conditions such as [Meningitis](/conditions/meningitis/). Low blood sugar and [Hypoglycaemia](/conditions/hypoglycaemia/) can also trigger seizures.

Ask whether testing is needed, what warning signs to record, whether driving or swimming restrictions apply, and how to use any prescribed rescue medicine. Mention recent alcohol changes, because [Alcohol Use Disorder](/conditions/alcohol-use-disorder/) and withdrawal can be relevant to seizure assessment.
