“…Another possible explanation is that the greater cognitive effort required to execute standard mental tasks by those with untreated ADHD may foster hyperphagia. This interpretation is based on evidence that mental work substantially increases ad libitum food intake [15].…”

Attention-deficit/Hyperactivity Disorder: Associations with Overeating and Obesity

In the past decade, we have become increasingly aware of strong associations between overweight/obesity and symptoms of attention-deficit/hyperactivity disorder (ADHD) in children, adolescents, and adults. This review addresses the prevalence of the comorbidity and discusses some of the mechanisms that could account for their relationship. It is suggested that the inattentive and impulsive behaviors that characterize ADHD could contribute to overeating in our current food environment, with its emphasis on fast food consumption and its many food temptations. It is also proposed-based on the compelling evidence that foods high in fat, sugar, and salt are as addictive as some drugs of abuse-that excessive food consumption could be a form of self-medication. This view conforms with the well-established evidence that drug use and abuse are substantially higher among those with ADHD than among the general population.

“…Crianças com TDAH e TDC concomitante parecem falhar no planejamento motor e costumam ter déficits no aprendizado de tarefas inovadoras as quais não estão habituados (Pereira, Araújo, 2005 (Raberger, Wimmer, 2003;Stray et al, 2009), sendo tais achados semelhantes aos obtidos por Tseng et al 2004 Além do impacto negativo dos déficits motores na execução das atividades de vida diária, no funcionamento social e na autoestima de crianças com TDAH (Cummins et al, 2005), um mau desempenho motor na infância também tem sido associado a maiores riscos de obesidade no futuro (Riverin, Tremblay, 2009;Morano et al, 2011) e a prejuízos no desempenho escolar, uma vez que, o desenvolvimento motor e cognitivo ocorrem mutuamente, tornando estes indivíduos mais predispostos ao fracasso e a evasão escolar (Poeta, Rosa Neto, 2004).…”

Although quite overlooked, increasing evidence points to a significant association between attention-deficit/hyperactivity disorder (ADHD) and obesity. Here, we present an updated systematic review and a critical discussion of studies on the relationship between ADHD and obesity, with a particular emphasis on the possible behavioral, neurobiological, and genetics underlying mechanisms. Available empirically based studies indicate that the prevalence of ADHD in clinical samples of patients seeking treatment for their obesity is higher than that in the general population. Moreover, although still limited, current evidence shows that individuals with ADHD have higher-than-average body mass index z-scores and/or significantly higher obesity rates compared with subjects without ADHD. Three mechanisms underlying the association between ADHD and obesity have been proposed: (1) obesity and/or factors associated with it (such as sleep-disordered breathing and deficits in arousal/alertness) manifest as ADHD-like symptoms; (2) ADHD and obesity share common genetics and neurobiological dysfunctions, involving the dopaminergic and, possibly, other systems (e.g., brain-derived neurotropic factor, melanocortin-4-receptor); and (3) impulsivity and inattention of ADHD contribute to weight gain via dysregulated eating patterns. With regards to the possible clinical implications, we suggest that it is noteworthy to screen for ADHD in patients with obesity and to look for abnormal eating behaviors as possible contributing factors of obesity in patients with ADHD. If further studies confirm a causal relationship between ADHD and obesity, appropriate treatment of ADHD may improve eating patterns and, as a consequence, weight status of individuals with both obesity and ADHD.
