Yes, Managing stress can have a positive impact on dopamine levels in individuals with Parkinson's disease.  High levels of stress can impede the production and utilization of dopamine, which can worsen symptoms such as tremors and freezing of gait, in addition to reducing the effectiveness of medication.  Effective techniques for stress management, such as relaxation, yoga, breathing exercises, walking, and stress relief supplements, may improve dopamine regulation and symptom management for individuals with Parkinson's disease.
