What was done
A scoping review was conducted across PubMed, Web of Science, Embase, and Scopus databases to map literature on pharmacological, psychological, and neuromodulatory rehabilitation strategies for pathological gambling in Parkinson's disease.
What was found
Of 537 identified records, 5 studies met inclusion criteria. Pharmacological approaches (dopamine agonist adjustments, naltrexone, and amantadine) demonstrated partial efficacy but were limited by significant side effects. Deep brain stimulation showed potential via limbic circuit modulation but carried risks such as apathy and transient symptom worsening. Cognitive-behavioral therapy was identified as the most effective strategy for modifying gambling behaviors. The abstract provides no quantitative values, sample sizes, or effect estimates.
Why it matters
Pathological gambling is a severe non-motor complication often triggered by dopaminergic therapies in Parkinson's disease; this review highlights a profound scarcity of clinical evidence to guide rehabilitation approaches.
Limits
The evidence base is extremely small (5 studies). The abstract provides no statistical data, patient counts, or specific study designs, and notes an absence of large-scale comparative trials and long-term efficacy outcomes.
