Eating disorders, such as anorexia, bulimia, and binge eating disorder, commonly involve a dysregulation of behavior (e.g., a lack or excess of inhibition and impulsive eating patterns) that is suggestive of prefrontal dysfunction. Functional neuro-imaging studies show that prefrontal-subcortical systems play a role in eating behavior and appetite in healthy individuals, and that people with eating disorders have altered activity in these systems. Eating behavior is often disturbed by illnesses and injuries that impinge upon prefrontal-subcortical systems. This study examined relationships between executive functioning and eating behavior in healthy individuals using validated behavioral rating scales (Frontal Systems Behavior Scale and Eating Inventory). Correlations demonstrated that increased dysexecutive traits were associated with disinhibited eating and greater food cravings. There was also a positive association with cognitive restraint of eating, suggesting that increased compensatory behaviors follow disinhibited eating. These psychometric findings reinforce those of other methodologies, supporting a role for prefrontal systems in eating.

    • "Elevated body mass index (BMI) has been associated with reduced cognitive performance in community samples of older adults, middle-age adults, and young adults, specifically in the areas of memory and executive function (Elias, Elias, Sullivan, Wolf, & D'Agostino, 2003; Gunstad et al., 2007). Further, studies of community-dwelling adults have found dysexecutive traits to be positively associated with disinhibited eating and greater food cravings (Spinella & Lyke, 2004), and decision making impairments to be positively associated with higher BMI's (Davis, Levitan, Muglia, Bewell, & Kennedy, 2004).

    ABSTRACT: Obesity is a leading cause of preventable death in America and its prevalence is increasing at an alarming rate. While it is known that individuals with specific obesity-related medical conditions perform poorly on neuropsychological tasks, recent evidence suggests that cognitive dysfunction in obese individuals may occur independently of medical co-morbidities. This study examined neuropsychological performance in a clinical sample of extremely obese patients. Individuals seeking surgical treatment of obesity (N=68) were administered cognitive tests as part of a standard pre-surgical evaluation. Results indicated significant differences in performances of extremely obese individuals on tests of executive functioning (planning, problem solving, mental flexibility) in comparison to normative data. No significant differences emerged between obese patients with and without co-morbid medical conditions of hypertension, type II diabetes, and obstructive sleep apnea on the neuropsychological tasks specific to executive functioning. Taken together, these results provide further evidence of specific cognitive dysfunction in extremely obese individuals.

    ABSTRACT: The number of homeless individuals in the U.S. has continued to increase, with men comprising the majority of this population. These men are at substantial risk for neuropsychological impairment due to several factors, such as substance misuse, severe mental illness, untreated medical conditions (e.g., diabetes, liver disease, HIV/AIDS), poor nutrition, and the increased likelihood of suffering a traumatic brain injury. Impairments in attention, memory, executive functioning, and other neuropsychological domains can result in poor daily functioning and difficulty engaging in psychological, medical, or educational services. Thus, knowledge of the neuropsychological functioning of homeless men is critical for those who work with this population. Yet data in this area are limited. This study aimed to describe the functioning of men residing in an urban homeless shelter across the domains of attention/concentration, memory, executive functions, language, sensory-motor abilities, general intelligence, and reading ability. Particular areas of impairment included attention, visual memory, cognitive flexibility, balance/coordination, and fine motor control. Correlational analyses found that educational background and ethnicity were linked to test performance, and the results of cluster analysis found two distinct subgroups based on neuropsychological functioning: an "average" group and a "low average/impaired" group. Caveats in interpreting test scores, particularly in the domain of language, are discussed, along with possible explanations for differences between African American and non-African American participants. Based on the findings of this study, it is recommended that clinicians and other service providers working with men residing in homeless shelters consider the possibility of neuropsychological impairment when developing treatment plans. Specific recommendations for each subgroup are discussed. Future research in this area might also explore the utility of offering skill-enhancing interventions within homeless shelters, such as workshops to improve organizational and planning skills. Further, the development of adequate norms for neuropsychological tests that are to be used with homeless individuals is recommended, given the possibility of low educational attainments and below average reading skills in this population.
