Mood and behaviour syndromes interact in Parkinson’s disease

Takeaway

  • Apathy and impulse control disorders (ICD) commonly co-occur in individuals with Parkinson’s disease (PD). ­­

Why this matters

  • This study challenges the idea that apathy and ICD in PD are mutually exclusive and exist on opposite ends of a motivational spectrum.

  • Furthermore, these behaviours interact with mood in clinically relevant ways that may affect the design of future clinical trials and the development of treatments.
