Influence of acoustic deep sleep enhancement on symptoms and laboratory parameters in patients with Parkinson's disease and mild cognitive impairment
Summary description of the study
Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease. Mild cognitive impairment (MCI), typically the amnestic type (aMCI), often precedes Alzheimer's disease. Excessive daytime sleepiness is a common and difficult-to-treat symptom in PD patients that has a strong impact on many other symptoms and quality of life as such. Sleep disturbances are also common in MCI patients and can exacerbate cognitive impairment and psychological symptoms. Both diseases are progressive, as there are only selectively symptomatic, not etiological treatments. Our group provided class I evidence that the drug sodium oxybate improves excessive daytime sleepiness in PD patients by promoting deep sleep. Acoustic stimulation is a new, non-invasive method for enhancing deep sleep. The study is a randomized, double-blind, placebo-controlled crossover study to assess the non-pharmacological improvement of deep sleep in PD and MCI patients through acoustic stimulation. Both patient populations will be randomized into two groups: Group 1 will initially be treated for 2 weeks with acoustic stimulation and - after a washout period of 2-4 weeks - switched to a two-week placebo stimulation. Group 2 will initially receive a two-week placebo stimulation and then switch to a two-week treatment with acoustic stimulation. The primary outcome is the objectively measured differences in excessive daytime sleepiness in PD patients and memory function in MCI patients after two weeks of stimulation versus placebo stimulation. Secondary outcomes are changes in subjective momentary sleepiness throughout the day, vigilance, restorative quality of nighttime sleep, and biomarker levels in the blood.

Intervention under investigation
Patients receive acoustic stimulation every night during sleep for two weeks using a portable, safe home device (TSB Axo). This medical device records biosignals (EEG) and plays precise sounds (approximately 50 dB, max. 80 dB) that are time-synchronized with the upward phase of deep sleep waves.

Disease under investigation
Parkinson's disease (also known as Morbus Parkinson or idiopathic Parkinson's syndrome) or mild cognitive impairment (also known as mild cognitive impairment, MCI)
(BASEC)
- Diagnosis of Parkinson's disease (PD; also known as Morbus Parkinson or idiopathic Parkinson's syndrome) or diagnosis of mild cognitive impairment (MCI; English Mild Cognitive Impairment), according to international criteria. - for PD: mild to moderate disease severity (Hoehn and Yahr scale II-III) - for MCI: predominant amnestic presentation (single or multi-domain aMCI) (BASEC)
Exclusion criteria
- Severe illnesses such as renal failure, liver failure, or congestive heart failure - Pregnant and breastfeeding women - for PD: deep brain stimulator (BASEC)
