The Cognitive Neuropsychiatry of Parkinson's Disease

This chapter finds that Parkinson’s disease (PD) manifests itself in the agentic self impairments, which emerge due to weak cognitive processes and lack of coordination in neural networks. The impaired agentic self gives rise to anxiety and restlessness, resulting in problematic sleeping or sleep behavior disorder (SBD) in PD patients. Patients suffering from SBD are unable to sleep peacefully and reach the rapid eye movement stage, which helps in consolidating neural activities and memory. Sleep disorders result in obstructions in normal memory and learning functions, and reduce the ability to focus or remain attentive during a task when awake. Disruptions in such cognitive activities lead to psychiatric disorders, which play a key role in the onset of PD. Disturbed sleep also has a significant adverse impact on the moods of the patients, resulting in unstable mood swings and irritation.
