Variante clínica da demência da doença de Alzheimer, que se apresenta com déficits predominantes de percepção visual e/ou visuoespaciais com função visual primária intacta. Manifestações clínicas incluem elementos da síndrome de Balint (ataxia óptica, apraxia ocular e simultagnosia) associados ou não à síndrome de Gerstmann (acalculia, agrafia, desorientação direita-esquerda e agnosia digital). A memória episódica está proporcionalmente menos comprometida. Há atrofia proeminente nas regiões corticais posteriores à ressonância magnética e hipometabolismo no exame FDG-PET. | |||
