Visuospatial deficits have been ocassionally reported but never
systematically studied in atypical parkinsonian syndromes. The
interpretation of existing studies is complicated by the possible
influence of motor and frontal executive deficits. Moreover, no
attempt has been made to distinguish visuoperceptual from visuospatial
tasks. The aim of the present study was to assess visuoperceptual
and visuospatial abilities in three atypical parkinsonian syndromes
while minimising the influence of confounding variables.
