Abstract

Abstract Optic aphasia is characterized by a deficit in naming objects presented visually, as a result of left occipito-temporal lesion. It differs from other neuropsychological disorders due to the nature of the deficits and impairment of cognitive function. A 52 year-old patient, admitted after an episode of sub-acute infarction in the territory of the left posterior cerebral artery involving the temporo-occipital region, was submitted to neuropsychological evaluation as part of a diagnostic investigation and presented specific characteristics of this disorder, as well as impairment to episodic memory. The relevance of the present case is justified not only due to the rarity of the disorder, but also because it highlights the importance of differential diagnosis in the treatment of patients.Resumo Afasia óptica consiste num déficit de nomear objetos apresentados visualmente como resultado de lesão occipito-temporal esquerda. Difere de outras desordens neuropsicológicas devido à natureza do déficit e comprometimento de funções cognitivas. Um paciente de 52 anos, internado após episódio de infarto subagudo em território de artéria cerebral posterior esquerda com acometimento da região têmporo-occipital, foi submetido à avaliação neuropsicológica como parte de investigação diagnóstica e apresentou características específicas desta desordem, bem como comprometimento de memória episódica. A relevância deste estudo é justificada não somente pela raridade com que a afasia óptica se apresenta, mas porque evidencia a importância do diagnóstico diferencial no tratamento dispensado aos pacientes.
