This systematic review and meta-analysis investigated visuospatial attentional deficits in right-handed, cognitively unimpaired patients with Parkinson's disease (PD). The analysis of 51 studies revealed that PD patients exhibited significant impairments in sustained, selective, and divided attention, particularly in exogenous orienting, while alerting and endogenous orienting remained intact. The findings underscore the cognitive challenges faced by PD patients, especially under demanding conditions.

Key findings

  • PD patients showed deficits in sustained, selective, and divided attention.
  • Only exogenous orienting was impaired, while alerting and endogenous orienting were preserved.
  • Visuospatial bias indicated small, context-dependent shifts in spatial attention.
  • Right-predominant motor symptoms were associated with subtle rightward spatial tendencies.

Why it matters

Understanding attentional deficits in Parkinson's disease is crucial for clinicians as it informs cognitive assessments and rehabilitation strategies, ultimately enhancing patient care and management.
