Acute psychotic disorder and hypoglycemia.

A variable array of neuroglycopenic symptoms are frequently encountered in the hypoglycemic stage, but acute psychotic disorders are quite rare. A fifty five year old female presented with an acute psychosis following oral sulfonylurea induced hypoglycemia without preceding features of adrenomedullary stimulation. This case report suggests that an acute and transient psychotic disorder may be an important neuroglycopenic feature and its early recognition protects the patient from severe hypoglycemic brain damage in a state of hypoglycemia unawareness.
