Objetivo. O objetivo foi avaliar déficit específico na Teoria da Mente comparando-se pacientes com demência frontotemporal e doença de Alzheimer. Método. administraram-se testes neuropsicológicos, de função executiva, escala de depressão de Yesavage e teste de Teoria da Mente utilizando o Teste de Histórias Estranhas de Happé para avaliar capacidade de inferir os estados mentais e interpretar afirmações não literais (metafóricas). Foram avaliados 20 pacientes com demência Alzheimer e 20 pacientes com demência Frontotempral, pareados por idade, sexo, escolaridade e IQ. Os dados foram analisados com teste ANOVA e correlação. Resultados. os pacientes com demência frontotemporal tiveram pior desempenho que os pacientes com doença de Alzheimer no teste de Histórias Estranhas, mas tiveram um desempenho similar na tarefa de controle de eventos físicos. Estes resultados não mostraram uma correlação significante com os testes de função executiva. Ambos grupos tiveram poucas respostas corretas de conteúdo contextual, mas a percentagem foi menor (pior desempenho) para demência frontotemporal. Estes resultados tiveram uma correlação positiva com maior hipometabolismo cerebral nas áreas ventromedial e dorsolateral, demonstrada em imagens de SPECT. Conclusões. os pacientes com Demência têm um déficit específico em Teoria de Mente o que os volta incapazes de construir inferências sobre os estados mentais.
