Factors associated with sleep disorders in elderly patients with Parkinson’s disease and cognitive impairment and the nomogram model development

There are numerous factors associated with sleep disorders in elderly patients with Parkinson's disease and cognitive impairment, primarily including Hoehn-Yahr staging, equivalent dose of levodopa, HAMA, HAMD, and chronic pain. The risk prediction nomogram model constructed based on these factors has certain predictive value for the occurrence of sleep disorders, can assist in the early screening of high-risk populations in clinical practice, and provides a basis for developing corresponding relaxation training interventions to reduce the occurrence of sleep disorders.
