Infantile seizures caused by voluntary water intoxication

Am J Emerg Med. 1986 Jan;4(1):21-3. doi: 10.1016/0735-6757(86)90244-5.


A case of infantile seizures of unusual etiology and presentation is described. Water intoxication with resultant epilepticus was caused by ingestion of nearly 150 ml/kg of fresh water on the day of presentation. It is unclear why the infant voluntarily consumed so much water, but heat illness is the most probable cause.
