Dermatological Manifestations of Parkinson's Disease: Clues for Diagnosis.

Background and objective Parkinson's disease (PD) is a common neurodegenerative disorder. There are various manifestations of PD. Among them, motor dysfunction has been studied in many research studies; however, few studies are available related to the dermatological manifestations of PD. This study was conducted with the aim to shed light on various skin conditions that occur in PD. Methods This cross-sectional study was conducted at a tertiary care hospital in Pakistan for a period of nine months; 107 patients with PD were included after obtaining informed consent. A self-administrated questionnaire was used to record demographic data and dermatological findings. Results Among the various dermatological manifestations, patients with PD most commonly presented with seborrheic dermatitis (46.7%) and rosacea (10.2%). Other manifestations included bullous pemphigoid (7.4%) and melanoma (4.6%). Conclusion The study revealed several dermatological manifestations of PD, which usually get overlooked by neurologists. Through this study, we want to emphasize that PD, apart from all the motor signs and symptoms, can also present as skin problems, and hence, a multi-disciplinary approach should be taken while managing PD.
