ABSTRACT: This article reviews the syndrome pseudoparkinsonism, a movement disorder described in the literature that resembles parkinsonism but differs qualitatively. Patients with this disorder have apraxic slowness, paratonic rigidity, frontal gait disorder and elements of akinesia that, taken together, may be mistaken for true parkinsonism. Pseudoparkinsonism appears to be common and is most often due to Alzheimer’s disease or vascular dementia. It seems that patients with even mild cognitive deficits can present with pseudoparkinsonism and that the primary dementing disorder may be overlooked. The authors emphasize the importance of pseudoparkinsonism and implications for clinical diagnosis, treatment and research.
