Decision Making assessed by the Iowa Gambling Task and Major Depressive Disorder A systematic review

: O Transtorno Depressivo Maior (TDM) pode ocorrer em paralelo com o comprometimento cognitivo. A busca por um perfil neuropsicologico da depressao tem sido perseguida nas ultimas duas decadas. No entanto, poucas pesquisas foram feitas sobre funcoes executivas e capacidade de decisao (DM). Objective: To perform a systematic review of the evidence of DM performance evaluated using the Iowa Gambling Task (IGT) in adults with MDD. Methods: A systematic search according to the PRISMA statement was performed on MEDLINE for studies in English using the following keywords: 'depression', 'depressive', 'depressive symptoms' AND 'decision making' OR 'game task'. Results: Five articles that met the inclusion and exclusion criteria were identified. Three reported significant differences between depressed and non-depressed individuals. The results indicated that young adults with MDD exhibited lower performance on all or almost all stages of the IGT. One study that evaluated DM in older adults with MDD showed that depressed non-apathetic participants failed to adopt any advantageous strategy and continued to make risky decisions during the task. Conclusao: Os resultados sugerem que o desempenho na tarefa de DM por jovens e adultos idosos com TDM diferiu em comparacao com os participantes nao deprimidos. Dado o pequeno numero de artigos, mais estudos devem ser realizados.
