Deep brain stimulation (DBS) has gained widespread acceptance for improving motor function and disability in Parkinson's disease (PD). Patients with features suggestive of atypical parkinsonism (AP) usually have a poorer and less sustained response to levodopa and a poorer prognosis overall when compared with patients with PD. However, experience in the use of DBS with this group of patients is limited and evidence is lacking with regards to its efficacy and adverse effects. We review in detail the experience of DBS surgery in patients with several forms of AP including multiple system atrophy. On the basis of the limited available data reviewed here, DBS for patients with AP is not recommended. © 2007 Movement Disorder Society
