Attentional and motor impulsivity interactively predict ‘food addiction’ in obese individuals

Impulsivity is a multifaceted construct and constitutes a common risk factor for a range of behaviors associated with poor self-control (e.g., substance use or binge eating). The short form of the Barratt Impulsiveness Scale (BIS-15) measures impulsive behaviors related to attentional (inability to focus attention or concentrate), motor (acting without thinking), and non-planning (lack of future orientation or forethought) impulsivity. Eating-related measures appear to be particularly related to attentional and motor impulsivity and recent findings suggest that interactive effects between these two facets may play a role in eating- and weight-regulation.

CONCLUSIONS: This is the first study to assess the effectiveness of CR-CBT in the treatment of obesity. Preliminary indications of treatment success are discussed with respect to study limitations. In light of these results, we recommend further investigation via a randomised control trial (RCT). LEVEL OF EVIDENCE: Level IV, case series. PMID: 31797330 [PubMed - as supplied by publisher]

CONCLUSION: Despite the low concordance with the EDE interview in terms of detecting the presence of BED, the QEWP-5 may be a useful initial screening tool for the clinical assessment of adults seeking treatment for obesity. LEVEL OF EVIDENCE: Level V, Descriptive study. PMID: 31784945 [PubMed - as supplied by publisher]

CONCLUSIONS: The combination of liraglutide and IBT was associated with greater short-term improvements in dietary disinhibition, global eating disorder psychopathology, and shape concern than IBT alone. PMID: 31746553 [PubMed - in process]

CONCLUSIONS: We did not find convincing evidence of comprehensive naturalistic chocolate reward memory reconsolidation blockade by rapamycin. The effects on chocolate bingeing and food choices may warrant further investigation. These limited positive findings may be attributable to insufficient interference with mTOR signalling with 10 mg rapamycin, or failure to destabilise chocolate memories during retrieval.

Discussion: BED appears to be associated with motor disinhibition and impaired executive planning even controlling for obesity. Longitudinal work is needed to clarify whether motor impulsivity predisposes people to BED, and/or contributes to persistence of symptoms over time.Key pointsBinge-eating disorder is common, under-recognised, and associated with untoward physical and health sequelae.The neurobiological basis of binge-eating disorder is unclear; cognitive testing may offer insights.Many prior cognitive studies have not controlled for potential confounds, especially group differences in body mass indices (BMI). Obes...

CONCLUSIONS: EDs were significantly associated with lower HSUVs compared to people without such disorders. This study, therefore, provides new insights into the burden of EDs. The derived HSUVs can also be used to populate future economic models. PMID: 31670627 [PubMed - as supplied by publisher]

This article provides a review of the preclinical and clinical pharmacology of lorcaserin, including its pharmacokinetic and safety profiles. Preclinical studies with lorcaserin initially focused on simple measures of food intake and body weight gain, but have now expanded to include studies on its effects on appetitive aspects of feeding behaviour and models of binge-eating. A significant number of studies have also shown that lorcaserin alters behaviours related to drug use and addiction, in rodents and non-human primates. Potential clinically-relevant effects of lorcaserin have also been reported in models of pain and s...
