title: Cognitive deficits presenting as psychiatric symptoms in a patient with Moyamoya disease.
abstract: The case of a middle-aged man who had intraventricular hemorrhages secondary to Moyamoya disease (MMD), and initially, presented with psychiatric symptoms which did not respond to treatment is described. Neuropsychological assessment showed underlying significant cognitive deficits, mostly of complex attention and speed of information processing, visuospatial and constructional abilities, verbal and nonverbal memory, and executive functions. These deficits remained stable or slightly improved in follow-up assessments. Cognitive dysfunction should be suspected in case of psychiatric or psychiatric-related symptoms in MMD patients. This case study in Greece highlights the range of preserved and impaired cognitive functions in adult MMD by means of repeated neuropsychological evaluations in which a broad range of cognitive abilities were assessed.
