What should you know about petit mal seizure?

During an absence seizure, a person may stare blankly, stop speaking, or pause an activity and then resume without realising what happened. Small eyelid or mouth movements can occur. Episodes can be mistaken for daydreaming, especially when they happen repeatedly. The older term petit mal is still heard, but clinicians generally use absence seizure and may need to distinguish it from other causes of altered awareness.

Stay with the person and move nearby hazards away. Do not restrain them, put anything in their mouth, or offer food or drink while awareness is interrupted. Note what happened, how long it lasted, and whether the person returned to normal afterwards. If episodes repeat, arrange a medical assessment; a clinician may ask for an eyewitness description or video recorded safely from a distance.

Seek urgent help if the person does not regain awareness, has trouble breathing, is injured, or develops a prolonged convulsion. New confusion with fever, severe headache, stiff neck, or a possible low blood sugar episode also needs urgent assessment. Do not assume every staring spell is epilepsy; fainting, medicines, alcohol withdrawal, or metabolic problems can look different and require their own evaluation.

Ask what features support an absence seizure, whether an EEG or other tests are appropriate, and what safety plan to follow at school, work, or home.
