Circadian Rhythms in Aging and Age-Related Neurogenerative Disease.
Purpose of review: Age-related changes in the circadian timing system may play a role in the development of disorders in older age. We review key aspects of the human circadian system that change with aging, discuss recent evidence of how changes in sleep and circadian rhythms manifest in neurodegenerative diseases, and summarize research on new therapies.
Recent findings: Several mechanisms have been proposed to underlie age-related changes in sleep and circadian rhythmicity. These mechanisms include changes in the suprachiasmatic nucleus, melatonin production, and light sensitivity as well as impaired glymphatic drainage, buildup of amyloid-beta, hypoxia from sleep-disordered breathing, and increased levels of orexin. While light-based therapies and lifestyle interventions have been under investigation for years, newer interventions include treatment with orexin antagonists and gamma stimulation to improve sleep and circadian rhythmicity.
Summary: Despite growing interest, our understanding of how sleep and circadian rhythms contribute to the development of age-related neurodegenerative diseases is still limited. More research is needed to understand the bidirectional relationship between circadian rhythms, sleep, and neurodegenerative diseases to develop targeted interventions.
期刊介绍：
Current Sleep Medicine Reports aims to review the most important, recently published articles in the field of sleep medicine. By providing clear, insightful, balanced contributions by international experts, the journal intends to serve all those involved in the care and prevention of sleep conditions. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas such as insomnia, narcolepsy, sleep apnea, circadian rhythm disorders, and parasomnias. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An international Editorial Board reviews the annual table of contents, suggests articles of special interest to their country/region, and ensures that topics are current and include emerging research. Commentaries from well-known figures in the field are also occasionally provided.
