Night Eating Syndrome: Report of a family case

Night eating syndrome (NES) represents a circadian delay in the pattern of eating. As there are genetic links for other eating- and circadian-based disorders, it is likely that there is a genetic basis for NES as well. We present a family case study of three identified patients and their extensive family history of NES and co-morbid mood disorders. This case report suggested that NES may have a heritable feature, particularly nocturnal ingestions. Of the seven identified cases, four had co-morbid mood disorders, and all descended from a couple with bipolar disorder and delusional disorder. More work is needed to understand the extent of genetic influence on NES, and the relationship between NES and other psychiatric disorders. (C) 2016 Elsevier Ltd. All rights reserved.
