Chronic Musculoskeletal Pain and Risk of Incident Parkinson's Disease: A 13-Year Longitudinal Study

This large population-based cohort study of 355,890 participants followed for 13 years examined whether chronic musculoskeletal pain increases the risk of developing Parkinson's disease and related parkinsonism disorders. Results showed a dose-response relationship: participants with more widespread chronic pain sites had progressively higher risks of incident Parkinson's disease (11-49% increased risk depending on pain extent), though the mechanisms underlying this association remain unclear.

B-type natriuretic peptide in Parkinson's disease: a novel biomarker of dysautonomia

This study examines NT-proBNP levels as a potential biomarker for identifying cardiovascular autonomic dysfunction in Parkinson's disease patients. Elevated NT-proBNP was significantly associated with orthostatic hypotension and abnormal autonomic function tests, suggesting it may serve as an early indicator of cardiac autonomic denervation in PD.

Genetics of Parkinson's Disease: From Causes to Treatment

Parkinson's disease has a complex genetic architecture including five autosomal dominant forms, three recessive types, and multiple genetic risk factors such as SNCA and GBA1 variants, with approximately 15% of cases attributable to known genetic causes. Recent advances have enabled gene-targeted clinical trials and incorporation of genetic findings into a new biological classification system for Parkinson's disease.

Validation of 2015 MDS Parkinson Disease Diagnostic Criteria in Autopsy-Confirmed Cases: A Scoping Review

This systematic literature review (1988–2024) evaluated the validity of the 2015 International Parkinson and Movement Disorder Society diagnostic criteria using pathologically-confirmed PD cases, identifying which supportive criteria and red flags best distinguish PD from atypical parkinsonian disorders. The study found that excellent levodopa response and rest tremor were most useful for PD diagnosis, though some red flags (supranuclear gaze palsy, rapid gait progression, bilateral symptoms) occurred in >5% of confirmed PD cases, suggesting potential criteria refinement.

Pathogenic GRN Variants Found in 0.1% of Parkinson's Disease Patients: Implications for Differential Diagnosis

A study of over 18,500 PD patients identified pathogenic or likely pathogenic GRN variants in 24 patients (0.13%), suggesting that GRN-associated frontotemporal dementia can clinically mimic Parkinson's disease. The findings recommend comprehensive genetic testing including GRN analysis for patients with parkinsonism to improve diagnostic accuracy and inform treatment decisions.
