Sleep Disorders in Chronic Disease
Sleep disorders frequently accompany neurological and autoimmune diseases. REM sleep behavior disorder is a prodromal Parkinson's marker. Insomnia and fragmented sleep worsen disease progression across conditions.

- Parkinson's Disease — REM behavior disorder precedes motor PD by 10-15 years. Sleep fragmentation is nearly universal in PD.
- Alzheimer's Disease — Sleep disruption impairs glymphatic amyloid clearance, creating a vicious cycle of accumulation and further sleep disruption.

Frequently Asked Questions
What is REM sleep behavior disorder?
RBD involves acting out dreams (shouting, kicking, punching) during REM sleep due to loss of normal muscle atonia. It's the strongest prodromal marker for synucleinopathies — 80-90% of idiopathic RBD patients develop Parkinson's or dementia with Lewy bodies within 10-15 years. Early identification enables enrollment in neuroprotective trials.
Does sleep affect Alzheimer's progression?
Sleep is when the glymphatic system clears amyloid-beta from the brain. Disrupted sleep reduces clearance by up to 30%, accelerating plaque accumulation. CPAP for sleep apnea, melatonin for circadian rhythm, and sleep hygiene interventions are being studied as AD-modifying strategies.
