  • Bak, T.H., Caine, D., Hearn, V.C. & Hodges, J.R. (2006) Visuospatial functions in atypical parkinsonian syndromes. Journal of Neurology, Neurosurgery and Psychiatry, 77 (4): 454 - 456.

    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.
