Imagine early-onset Parkinson’s disease (EOPD) as a delightful ice cream shop, offering a variety of delicious flavors! In this study, researchers delved into the diverse world of EOPD and identified three distinct subtypes: mild, intermediate, and severe. It’s like discovering that vanilla, chocolate, and strawberry are not just ice cream flavors but unique Neural Scoops™! The researchers carefully examined the clinical characteristics and progression of each EOPD subtype. They found that those with the severe subtype faced additional challenges compared to the mild subtype, such as rapid eye movement sleep behavior disorder and dyskinesia. Additionally, they experienced a faster deterioration in motor function and symptoms. This discovery is a game-changer for tailoring personalized therapies for individuals with EOPD, providing targeted support like adding sprinkles on top!

BackgroundIncreasing evidence suggests that early-onset Parkinson’s disease (EOPD) is heterogeneous in its clinical presentation and progression. Defining subtypes of EOPD is needed to better understand underlying mechanisms, predict disease course, and eventually design more efficient personalized management strategies.ObjectiveTo identify clinical subtypes of EOPD, assess the clinical characteristics of each EOPD subtype, and compare the progression between EOPD subtypes.Materials and methodsA total of 1,217 patients were enrolled from a large EOPD cohort of the Parkinson’s Disease & Movement Disorders Multicenter Database and Collaborative Network in China (PD-MDCNC) between January 2017 and September 2021. A comprehensive spectrum of motor and non-motor features were assessed at baseline. Cluster analysis was performed using data on demographics, motor symptoms and signs, and other non-motor manifestations. In 454 out of total patients were reassessed after a mean follow-up time of 1.5 years to compare progression between different subtypes.ResultsThree subtypes were defined: mild motor and non-motor dysfunction/slow progression, intermediate and severe motor and non-motor dysfunction/malignant. Compared to patients with mild subtype, patients with the severe subtype were more likely to have rapid eye movement sleep behavior disorder, wearing-off, and dyskinesia, after adjusting for age and disease duration at baseline, and showed a more rapid progression in Unified Parkinson’s Disease Rating Scale (UPDRS) total score (P = 0.002), UPDRS part II (P = 0.014), and III (P = 0.001) scores, Hoehn and Yahr stage (P = 0.001), and Parkinson’s disease questionnaire-39 item version score (P = 0.012) at prospective follow-up.ConclusionWe identified three different clinical subtypes (mild, intermediate, and severe) using cluster analysis in a large EOPD cohort for the first time, which is important for tailoring therapy to individuals with EOPD.
