Article Abstract
Objectives: To examine whether initiation of an antidepressant is associated with the development of impulse control disorder (ICD) in patients with Parkinson's disease (PD).
Design: We performed a retrospective analysis utilizing data from the Parkinson's Progression Markers Initiative (PPMI). Two-sample Mann-Whitney tests were used for comparison of continuous variables and Pearson χ tests were used for categorical variables. Kaplan-Meier survival analysis and cox proportional hazards regression analysis was used to assess the hazard of ICD with antidepressant exposure.
Setting: The PPMI is a multicenter observational study of early PD with 52 sites throughout North America, Europe, and Africa.
Participants: Participants in the current study were those in the PPMI PD cohort with a primary diagnosis of idiopathic PD.
Measurements: The presence of ICD was captured using the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease (QUIP). Antidepressant use was defined based on medication logs for each participant. Depressive symptoms were captured using the Geriatric Depression Scale (GDS).
Results: A total of 1,045 individuals were included in the final analysis. There was a significant increase in the probability of ICD in those exposed to serotonergic antidepressants compared to those not exposed (Log-rank p <0.001). Serotonergic antidepressant use was associated with a hazard ratio for ICD of 1.4 (95% CI 1.0-1.8, z-value 2.1, p = 0.04) after adjusting for dopamine agonist use, depression, bupropion use, MAOI-B use, amantadine use, LEDD, disease duration, sex, and age.
Conclusions: Serotonergic antidepressant use appears to be temporally associated with ICD in patients with PD.

Background And Objectives: Years before diagnosis of Parkinson disease (PD), dementia with Lewy bodies (DLB), or multiple system atrophy (MSA), mild prodromal manifestations can be detected. Longitudinal follow-up of people with prodromal synucleinopathy, particularly idiopathic/isolated REM sleep behavior disorder (iRBD), enables in-depth clinical phenotyping of early disease, which could facilitate stratification for clinical trials, provide the definition of appropriate end points, or predict phenoconversion more precisely. The aim of this study was to update and expand on previous studies assessing clinical evolution from iRBD to clinically diagnosed disease, up to 14 years before diagnosis.

Parkinson's disease (PD) is a challenging neurodegenerative condition often prone to diagnostic errors, where early and accurate diagnosis is critical for effective clinical management. However, existing diagnostic methods often fail to fully exploit multimodal data or systematically incorporate expert domain knowledge. To address these limitations, we propose MKD-Net, a multimodal and knowledge-driven diagnostic framework that integrates imaging and non-imaging clinical data with structured expert insights to enhance diagnostic performance.

c-Jun N-terminal kinases (JNKs), a subfamily of mitogen-activated protein kinases (MAPKs), are key mediators of cellular responses to environmental stress, inflammation, and apoptotic signals. The three isoforms-JNK1, JNK2, and JNK3 exhibit both overlapping and isoform-specific functions. While JNK1 and JNK2 are broadly expressed across tissues and regulate immune signaling, cell proliferation, and apoptosis, JNK3 expression is largely restricted to the brain, heart, and testis, where it plays a crucial role in neuronal function and survival.

Background: The "Systematic Screening of Handwriting Difficulties in Parkinson's Disease" (SOS) test is the only tool specifically designed to evaluate handwriting in people with Parkinson's Disease (pwPD). It is language specific.
Objective: To assess the construct validity, intrarater and interrater reliability of the Italian version of the SOS test.
