Insulinoma Presenting as a Parasomnia Mimic Symptoms

Abstract

Parasomnia involve abnormal and unnatural movements, behaviors, emotions, perceptions, and dreams that occur while sleep. Chronic hypoglycemia causes neuroglycopenic symptoms such as mental confusion, abnormal behavior, personality change, diplopia, fatigue and headache without typical autonomic symptoms. We report a 59-year-old woman with hypoglycemia who initially developed parasomnia mimic symptoms in early morning sleep period and the final diagnosis was insulinoma. Abnormal nocturnal behaviors persist long duration in the fasting state or early morning, are considered as hypoglycemic symptoms of insulinoma
