| 520 | _ | _ | |a BackgroundSkin biopsies and seed amplification assays (SAA) provide a sensitive and potentially quantitative method to detect alpha-synuclein (a-syn) aggregation in peripheral nerve fibers in Parkinson's disease (PD). Relating to the previously published hypothesis that PD may either originate in the peripheral (body-first) or central (brain-first) nervous system, we investigated whether patients with clinical features that have been reported to be associated with a suspected body-first subtype of PD exhibit higher levels of a-syn aggregation in dermal nerve fibers compared to those without these features. Patients with isolated REM sleep behavior disorder (iRBD) representing a suspected premotor stage of body-first PD were studied in comparison to the PD cohort.MethodsPatients were categorized on the basis of clinical features, and SAA parameters such as lag time, number of positive curves, and titers were analyzed and correlated with clinical features.ResultsAlthough patients with clinical features of suspected body-first PD showed slightly higher titers, significant differences were mainly observed between iRBD patients and PD patients.ConclusionsOur data suggest that widespread α-syn aggregation in advanced PD limits the use of SAA in skin biopsies for subtype differentiation. |
