Research progress on the bidirectional relationship between sleep disorders and Parkinson's disease / 中华老年医学杂志

ABSTRACT

Parkinson's disease(PD)is a progressive neurodegenerative disorder that tends to occur in the elderly.Its clinical manifestations mainly include motor symptoms and non-motor symptoms, with sleep disorders among common non-motor symptoms of PD.The latest lines of evidence show that sleep disorders are not only clinical manifestations of neurodegenerative diseases, but also an important risk factor for the development and progression of neurodegenerative diseases.There is a bidirectional relationship between sleep disorders and neurodegenerative diseases, including PD.The possible mechanisms include accelerated α-synuclein pathology, deposition of Tau protein, inhibition of the glymphatic system, neuroinflammation and changes in the circadian rhythm system.In this article, we review research progress on the bidirectional relationship between sleep disorders and PD, related mechanisms, and the outlook on the treatment of PD through the management of sleep disorders.
