Nonmotor features in sex-linked dystonia parkinsonism

Abstract

SUMMARY  The natural history of sex-linked dystonia parkinsonism (XDP) has been well documented. However, its nonmotor features have not yet been fully described. We reviewed the available literature on the nonmotor features in XDP. We found five articles involving 79 XDP patients, three of which were on cognition and two on mood (anxiety and depression). There were two case reports showing executive dysfunction. The other paper showed impairments in abstract thinking and motor programming. Two articles were on mood (anxiety and depression). The prevalence of anxiety symptoms was 16.7% and 54.8–92.9% had depressive symptoms. The identification of these nonmotor features should lead to early and appropriate management.
