Resumo

Introdução. O fenômeno do envelhecimento populacional tem sido observado em todo o mundo. Neste contexto, está inserida a doença de Alzheimer, que é uma desordem neurodegenerativa progressiva ca­racterizada por um progressivo declínio da função congnitiva. Com­portamentos neuropsicológicos e não congnitivos ocorrem com fre­quência em pacientes idosos com a doença de Alzheimer. Dentre esses comportamentos, várias formas de distúrbios alimentares, incluindo a hiperfagia vem sendo reportado nos estudos. Portanto, esse trabalho tem como objetivo realizar uma revisão sobre os possíveis mecanis­mos responsáveis por essa mudança comportamental. Método. Foi realizada uma revisão de literatura, através de pesquisas bibliográficas na literatura, utilizando as bases eletrônicas no Lilacs® e Medline® via Pubmed® para buscar artigos de revistas e jornais científicos indexados, na língua inglesa, que fossem referentes ao assunto. Para tal finalida­de, utilizaram-se as palavras da língua inglesa: “Alzheimer´s disease”, “Hyperphagia”, “Behavioral disturbance”, “Dementia”. Conclusão. Nessa revisão, podemos verificar que mudanças no comportamento alimentar são comuns em pacientes com Alzheimer, mas que o meca­nismo exato para tal modificação ainda não está claro.
