Sleep-related eating disorder (SRED) is a parasomnia that arises primarily from NREM sleep with recurrent episodes of involuntary eating and drinking. This chapter discusses the case of a 32-year-old woman who presented with sleep-related eating episodes, who also had difficulty with sleep initiation insomnia, somnambulism, somniloquy and symptoms of restless legs syndrome (RLS) since she was 6 years old. It presents the clinical history, examination, follow-up, treatment, diagnosis, and the results of the procedures performed on the patient. Overnight diagnostic polysomnography (PSG) was performed. Based on the PSG results, a diagnosis of SRED was made. Complications include obesity, injuries, toxic ingestions and psychological distress with excessive weight gain. Treatment of the underlying sleep disorder, if present, is usually effective. Underlying mood disorder or alcohol or substance abuse should be addressed. Pharmacotherapy consists of administration of antidepressants (e.g. SSRIs), dopaminergic agonists or topiramate.
