ABSTRACT
Multiple system atrophy (MSA) is characterized by a variable combination of cerebellar ataxia, parkinsonism and pyramidal signs associated with autonomic failure. Classically, cognitive impairment was not considered a clinical feature of MSA and dementia was pointed out as an exclusion diagnostic criteria. Based on comprehensive neuropsychological assessment, cognitive impairment was found to be a frequent feature in MSA, and clinically-defined dementia is now reported in 14-16% of cases. This article reviews the current data on cognitive impairment in MSA along with its neuropsychological profile and pathophysiology.
RESUMO
A Atrofia de Múltiplos Sistemas (AMS) é caracterizada por uma combinação variável de ataxia cerebelar, parkinsonismo e sinais piramidais, associados à disfunção autonômica. Classicamente, o comprometimento cognitivo não é considerado como manifestação clínica da AMS e a demência é apontada como um critério de exclusão para o diagnóstico. Baseado na avaliação neuropsicológica ampla, o comprometimento neuropsicológico revelou-se frequente na AMS e a presença de demência é atualmente descrita em 14-16% dos casos. Este artigo revisa os dados atuais sobre o comprometimento cognitivo na AMS, seu perfil neuropsicológico e fisiopatologia.
