Abstract

A 29-year-old man with schizophrenia was admitted to the emergency department in a stupor following the first generalized tonicclonic seizure. He had drunk about 1.5 L of Coke and 2 L of water each day for 1 week without eating any other food. A laboratory evaluation revealed severe hyponatremia (110 mEq/L), and we diagnosed a hyponatremia-induced seizure. As polydipsia and hyponatremia are not uncommon in schizophrenics, hyponatremia-induced seizure should be included in the causes of seizure in schizophrenics.
