Femke Lamers, PhD, presented evidence based on the nearly 3,000-subject longitudinal Netherlands Study of Depression and Anxiety that roughly one-quarter of individuals with major depressive disorder have a distinct subtype of nonmelancholic depression characterized by a clustering of obesity, inflammation, increased appetite, fatigue, hypersomnia, and increased levels of insulin and leptin. She calls it immunometabolic depression. She and her coinvestigators in the international Psychiatric Genomics Consortium have demonstrated that this phenotypic clustering is associated with a shared genetic vulnerability between major depression and obesity (JAMA Psychiatry. 2017 Dec 1;74[12]:1214-25).
