A retarded boy with seizures precipitated by stepping into the bath water

This report describes the unusual case of a boy with partial deletion in the proximal region of a long arm of chromosome 2 and reflex epilepsy. Seizures with identical onset were precipitated predictably by two independent triggers, micturition and immersion of the feet in tepid or hot water. A seizure precipitated by immersion could be reproduced under video and EEG monitoring. The EEG seizure onset was in the central midline region.
