Absence seizures: signs, next steps, and urgent warnings

The person generally stops what they are doing, may blink or make subtle mouth movements, and resumes soon afterwards. There may be no fall or large jerking movement. Repeated episodes can interrupt lessons, conversations, or everyday tasks without being recognised as seizures.

A typical episode begins and ends abruptly. The person may stare ahead, stop speaking mid-sentence, and not answer until awareness returns. They often have no memory of the pause and are not confused for a long period afterwards.

Staring alone does not establish the diagnosis. Daydreaming, poor attention, faintness, migraine, sleep problems, medicines, and metabolic disturbances can alter awareness. Hypoglycaemia may cause sweating, trembling, confusion, or seizures and requires timely treatment. A clinician uses the witness account and may arrange an electroencephalogram to examine brain electrical activity.

Keep a record of the time, setting, responsiveness, eyelid or mouth movements, and behaviour immediately after each event. Ask teachers or family members to document what they see. A video made without delaying care or placing anyone at risk can give the clinician useful detail.

Book a medical appointment for recurrent unexplained staring or a first suspected seizure. Until assessed, take extra care around water, heights, traffic, hot surfaces, and machinery because a brief loss of awareness can cause injury. Do not start, stop, or alter seizure medicine without the prescribing clinician’s guidance.

Call emergency services if an episode continues for five minutes, seizures repeat without recovery, breathing becomes difficult, the person turns blue or grey, a serious injury occurs, or usual awareness does not return. Place someone who has fallen on their side when feasible, cushion the head, clear nearby hazards, and never put anything in the mouth.

Fever with severe headache, neck stiffness, a non-fading rash, vomiting, or pronounced drowsiness requires urgent assessment because meningitis can present with seizures. New seizure activity after heavy alcohol use or sudden cessation also needs urgent medical attention; alcohol use disorder can complicate withdrawal and seizure risk.

Discuss which features support or argue against absence seizures, whether glucose or other blood tests are relevant, and whether an electroencephalogram or neurology review is needed. Ask what activities require precautions and what family, school, or colleagues should do if another event happens.
