Diagnostic And Statistical Manual

Binge eating disorder (BED) is the most common eating disorder, with an estimated lifetime prevalence of 2.6% among U.S. adults, yet often goes unrecognized. In theDiagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), BED is defined by recurrent episodes of binge eating (eating in a discrete period of time an amount of food larger than most people would eat in a similar amount of time under similar circumstancesanda sense of lack of control over eating during the episode), occurring on average at least once a week for 3 months, and associated with marked distress. It can affect both men and women, regardless if they are at normal weight, overweight, or obese, and regardless of their ethnic or racial group. Psychiatric comorbidities are very common, with 79% of adults with BED also experiencing anxiety disorders, mood disorders, impulse control disorders, or substance use disorders; almost 50% of persons with BED have ≥3 psychiatric comorbidities. Multiple neurobiological explanations have been proffered for BED, including dysregulation in reward center and impulse control circuitry, with potentially related disturbances in dopamine neurotransmission and endogenous μ‐opioid signaling. Additionally, there is interplay between genetic influences and environmental stressors. Psychological treatments such as cognitive behavioral interventions have been recommended as first line and are supported by meta-analytic reviews. Unfortunately, routine medication treatments for anxiety and depression do not necessarily ameliorate the symptoms of BED; however, at present, there is one approved agent for the treatment of moderate to severe BED—lisdexamfetamine, a stimulant that was originally approved for the treatment of attention deficit hyperactivity disorder.

Objectively Measured

Obesity (OB) and associated binge-eating disorder (BED) show increased impulsivity and emotional dysregulation. Albeit well-established in neuropsychiatric research, functional near-infrared spectroscopy (fNIRS) has rarely been used to study OB and BED. Here, we investigated fNIRS-based food-specific brain signalling, its association with impulsivity and emotional dysregulation, and the temporal variability in individuals with OB with and without BED compared to an age- and sex-stratified normal weight (NW) group. Prefrontal cortex (PFC) responses were recorded in individuals with OB (n = 15), OB + BED (n = 13), and NW (n = 12) in a passive viewing and a response inhibition task. Impulsivity and emotional dysregulation were self-reported; anthropometrics were objectively measured. The OB and NW groups were measured twice 7 days apart. Relative to the NW group, the OB and OB + BED groups showed PFC hyporesponsivity across tasks, whereas there were few significant differences between the OB and OB + BED groups. Greater levels of impulsivity were significantly associated with stronger PFC responses, while more emotional dysregulation was significantly associated with lower PFC responses. Temporal differences were found in the left orbitofrontal cortex responses, yet in opposite directions in the OB and NW groups. This study demonstrated diminished fNIRS-based PFC responses across OB phenotypes relative to a NW group. The association between impulsivity, emotional dysregulation, and PFC hypoactivity supports the assumption that BED constitutes a specific OB phenotype.
