Serum hypomagnesemia is associated with febrile seizures in young children.

Serum magnesium was significantly low in febrile children with seizures compared to those without, and hypomagnesemia was associated with the occurrence of febrile seizures. These results portray hypomagnesemia as a possible risk factor for febrile seizure, and so should be validated in future large cohort studies so that guidelines are set for proper management of these children.
