Impact of Sleep on Progression of Parkinson's Disease

Unraveling the Link Between Slumber, Rhythms, and Parkinson's: A Deep Dive

By Dr. Mark Ryan - Consultant Psychiatrist and Clinical Director, Neurocare Clinics Australia

The intricate connection between sleep disorders, circadian rhythms, and Parkinson's disease (PD) warrants our attention. Sleep disturbances can be both a prelude to PD and a common symptom that accompanies the disease.

Sleep disorders and their impact on the development of PD are noteworthy. Long-term issues like insomnia and obstructive sleep apnea (OSA) have been associated with a higher risk of PD[1]. These sleep issues can manifest years before a formal PD diagnosis, leading some researchers to view them as potential early warning signs rather than mere symptoms of the disease.

Circadian rhythm disruptions also share a correlation with an elevated risk of neurodegenerative diseases, including PD[1]. These disturbances may disrupt the body's natural sleep-wake cycle, potentially exacerbating neurodegenerative processes.

When it comes to PD, several sleep disorders can reveal themselves. REM Sleep Behavior Disorder (RBD), for instance, is common among PD patients. This condition involves acting out dreams during REM sleep. RBD can serve as one of the earliest signs of PD and can even predate motor symptoms by several years[4]. In some cases, it can also impact partners, necessitating open communication and bedtime adjustments to prevent accidents during acted-out dreams[4].

The glymphatic system, which plays a crucial role in clearing neurotoxic proteins like alpha-synuclein during sleep, has recently come under the spotlight in relation to sleep apnea and PD. Impaired glymphatic function, potentially linked to sleep disturbances, could contribute to the acceleration of PD progression[5]. By improving sleep quality, we might potentially delay the progression of PD by optimizing these clearance mechanisms[5].

In conclusion, sleep disorders and circadian rhythm disruptions are intertwined with PD, serving as both risk factors and symptoms. They can influence the progression of the disease by affecting mechanisms like glymphatic system function. Addressing sleep issues is indispensable for managing PD and potentially slowing its progression.

Recommendations

Adopting a personalized medicine approach and delving beyond the labels and symptoms to identify underlying causal processes can yield valuable insights. Addressing these underlying issues, across the board, can lead to marked improvements in symptoms, quality of life, and functioning. This holistic approach, known as personalized or precision medicine, represents the future of best practices in PD management.

  1. In the field of science, the link between neurodegenerative diseases such as Parkinson's and sleep disorders, especially REM Sleep Behavior Disorder, is an area of significant interest.
  2. The chronic nature of sleep disorders like insomnia and obstructive sleep apnea, commonly known as medical-conditions, has been associated with a higher risk of developing Parkinson's disease.
  3. The disruption of circadian rhythms and the impact on mental-health, including an increased risk of neurodegenerative diseases like Parkinson's, is a growing area of concern in health-and-wellness research.
  4. Neurological-disorders, such as Parkinson's, are often associated with various sleep disorders, and addressing these sleep issues is crucial for managing these conditions and potentially slowing their progression.
