Resumo: | Introduction: Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. The relationship between ADHD and eating disorders (EDs) has been recently often considered. Both conditions tend to have an early age of onset and can become chronic and persist into adulthood. Objective: This study aimed to elucidate the prevalence and overlap of ADHD and EDs and review the current evidence about an association between both conditions. It also sought to investigate some of the mechanisms potentially underlying these comorbid disorders. Methods: A brief review of the latest literature was performed on PubMed using the terms “attention deficit hyperactivity disorder”, “ADHD”, “eating disorders”, and “ADHD and ED”. Results: The prevalence of EDs in individuals with ADHD has been reported across a range up to 12 %. The literature describes an association between childhood ADHD and the development of EDs during adolescence. Conversely, ADHD symptoms have been reported in patients with EDs, more frequently in those with bulimia nervosa and anorexia nervosa purging subtype than with anorexia nervosa restrictive subtype. Impulsive behaviors constitute a core ADHD symptom and deficits in its regulation have been shown in patients with EDs. Conclusion: Evidence in the literature suggests an overlap between ADHD and EDs. More studies are required to retrieve additional insights into the clinical management of patients with both conditions. |

Recentemente, a relação entre PHDA e perturbações do comportamento alimentar tem sido repetidamente equacionada. Ambas tendem a manifestar-se em idade precoce, podendo tornar-se condições crónicas e persistir na idade adulta. Objetivos: Este estudo teve como objetivo elucidar a prevalência, sobreposição diagnóstica e semelhanças entre PHDA e perturbações do comportamento alimentar. Métodos: Foi efetuada uma revisão bibliográfica da literatura na base de dados PubMed utilizando os termos “attention deficit hyperactive disorder”, “ADHD”, “eating disorders” e “ADHD and ED”. Resultados: A maior parte dos estudos sugere uma prevalência de perturbações do comportamento alimentar em doentes com PHDA superior a 12%, existindo uma associação entre o diagnóstico de PHDA durante a infância e o desenvolvimento de perturbações do comportamento alimentar durante a adolescência. As perturbações do comportamento alimentar mais frequentemente associadas a PHDA são a perturbação de ingestão alimentar compulsiva e a bulimia nervosa. Por outro lado, a prevalência de PHDA varia entre 1.6─18% em indivíduos com perturbações do comportamento alimentar, sendo mais comum naqueles com anorexia nervosa do tipo purgativo e bulimia nervosa. Doentes com PHDA e perturbações do comportamento alimentar partilham determinadas características, como impulsividade, mecanismos de recompensa alterados, baixa auto-estima, défice de atenção e perturbação de funções executivas, que levam a um controlo motivacional disfuncional. Discussão: É recomendada a investigação da sintomatologia de PHDA como parte integrante da avaliação das perturbações do comportamento alimentar. A associação entre ambas pode ser explicada pela combinação de mecanismos genéticos relacionados com vias dopaminérgicas ligadas ao processo de recompensa. A presença de sintomas de PHDA correlaciona-se com a gravidade da sintomatologia das perturbações do comportamento alimentar e é preditiva da gravidade da compulsão alimentar e sintomas bulímicos. Conclusões: Existe uma sobreposição diagnóstica entre PHDA e perturbações do comportamento alimentar. São necessários estudos adicionais para esclarecer as implicações clínicas e terapêuticas da comorbilidade destas duas condições.Centro Hospitalar Universitário do Porto2022-06-30T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.25753/BirthGrowthMJ.v31.i2.24118eng2183-9417Rodrigues, MárciaAzevedo, Patríciainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-21T14:55:43Zoai:ojs.revistas.rcaap.pt:article/24118Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:56:33.452092Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
