Resumo

Com o envelhecimento da população global, cresce a demanda por intervenções capazes de combater o declínio cognitivo. O neurofeedback (NFB), uma técnica não invasiva de treinamento cerebral, tem demonstrado potencial para melhorar funções cognitivas em idosos. Esta revisão sistemática teve como objetivo avaliar os efeitos do NFB na cognição de pessoas idosas. O estudo seguiu as diretrizes PRISMA e utilizou a estratégia PICO para estruturar a pergunta de pesquisa. As buscas foram realizadas nas bases PubMed, Scopus e Web of Science, contemplando artigos publicados entre 2014 e 2024. O risco de viés foi avaliado por meio das ferramentas Cochrane RoB 2 e ROBINS-I. Dos 452 estudos inicialmente identificados, 12 atenderam aos critérios de inclusão. A maioria dos estudos (75%) incluiu idosos saudáveis, sendo que 58% investigaram exclusivamente essa população. Além disso, 42% das pesquisas incluíram participantes com condições clínicas, como doença de Alzheimer, amnésia, acidente vascular cerebral ou tumores malignos. O treinamento com neurofeedback baseado no ritmo sensório-motor (SMR) demonstrou benefícios na memória de trabalho e na memória verbal em idosos saudáveis, enquanto pacientes pós-AVC apresentaram melhora significativa no Mini Exame do Estado Mental após as intervenções com NFB. Protocolos focados em ondas alfa favoreceram melhorias na memória episódica, na atenção e na velocidade de processamento cognitivo. Entretanto, em indivíduos com doença de Alzheimer, o NFB contribuiu para a estabilização do declínio cognitivo, sem promover ganhos significativos. Os achados sugerem que o NFB possui potencial terapêutico para otimizar o desempenho cognitivo em idosos, especialmente em domínios como memória e atenção. Contudo, a heterogeneidade entre os estudos, incluindo variações nos protocolos de NFB e nas características das populações avaliadas, limita a generalização dos resultados.
