An Overlapping Presentation of Hypoglycemia and Catatonia—A Case Report and Literature Review

Abstract

Catatonia is a clinical syndrome characterized by a distinct constellation of psychomotor disturbances. It is known as a clinical manifestation of many medical and psychiatric conditions. Neuroglycopenia is a term that refers to a shortage of glucose in the brain resulting in the alteration of neuronal function. Catatonia has been observed in hypoglycemic states. We present a single case report of a 36-year-old male, with no known medical or psychiatric history, presenting with catatonia and hypoglycemia due to malnutrition. Catatonia and hypoglycemia may present similarly, and can present a challenge in differentiating the underlying etiology. It is unclear whether the hypoglycemia-catatonia overlap phenomenon is rare or rather underdiagnosed.
