Acute confusional state in type 2 diabetic patient: non-convulsive status epilepticus.

The etiology of acute confusional state in elderly patients with type 2 diabetes mellitus is broad, including hypoglycemia or hyperglycemia, electrolyte imbalance as hyponatremia or hypercalcemia, cerebrovascular disease and drug intoxication among others. Herein, we present an 80-year-old female type 2 diabetic patient in an acute confusional state due to non-convulsive status epilepticus (NCSE). Timely electroencephalogram at an emergency department when available is the only tool for the diagnosis of NCSE when clinically suspected. All clinicians must consider the possibility of NCSE in the differential diagnosis of acute confusional patients when diagnosis is uncertain.
