Hyperammonemia causes several alterations, mainly in the central nervous system. If hepatic failure is not its etiology, other less frequent causes must be investigated in the search for a definitive diagnosis. ⋯ The complex management of hyperammonemia and the high morbidity and mortality involved require a multidisciplinary approach. Only early treatment and identification of the hyperammonemia's etiology can avoid high morbidity and mortality in these patients.
