Original abstract
BackgroundDepression is one of the most prevalent and disabling non-motor symptoms in Parkinson's disease (PD), forming a bidirectional relationship with motor dysfunction that worsens quality of life. Pharmacological treatments exhibit limited and inconsistent efficacy, and may lead to adverse interactions. Acupuncture may improve both depressive and motor symptoms by regulating the neuro-immune-endocrine network, but high-quality evidence remains insufficient.ObjectiveThis study aims to evaluate the efficacy and safety of acupuncture as an adjunctive therapy for depression in PD and to explore potential biological correlates of clinical changes using predefined serum biomarkers.MethodsIn this single-center, evaluator-blinded, randomized controlled trial, 88 patients with PD and comorbid depression will be randomly assigned to an acupuncture group or a waitlist control group. The primary outcome is the change in the Montgomery-Asberg Depression Rating Scale (MADRS) score. Secondary outcomes include motor function, anxiety, sleep quality, and overall quality of life. Exploratory analyses will assess serum inflammatory cytokines, brain-derived neurotrophic factor (BDNF), and kynurenine/tryptophan (KYN/TRP) ratio.Expected resultsWe hypothesize that adjunctive acupuncture may improve depressive and motor symptoms compared with the control. Exploratory analyses will examine whether clinical changes are associated with changes in relevant biomarkers.ConclusionThis study will provide rigorous evidence for acupuncture as an adjunctive therapy, offering a non-pharmacological strategy to optimize the comprehensive management of PD and disrupt the bidirectional emotion-motor interplay.Clinical trial registrationhttps://www.chictr.org.cn/, identifier ChiCTR2500113443.
