Auditory Slow Wave Enhancement in Parkinson Disease & Mild Cognitive

Status Recruiting

Clinical Trial Summary

The study aims to assess the efficacy of auditory slow-wave sleep (SWS) enhancement in PD patients and patients with amnestic MCI. Patients will be randomized to two groups: Group 1 will first be treated with auditory stimulation for two weeks and then - after a washout period - switched to two weeks of sham stimulation. Group 2 will first receive sham stimulation for two weeks and then - after a washout period - switch to two weeks of auditory stimulation treatment. The washout period in between will be 2-4 weeks.

Clinical Trial Description

The study is a randomized, double-blind, sham-controlled cross-over trial to assess the efficacy of auditory slow-wave sleep (SWS) enhancement in PD patients and patients with amnestic MCI. The screening phase includes entry questionnaires about inclusion/exclusion criteria, sleep quality, chronotype, and handedness, and 1-4 screening nights at home with the TSB Axo, to allow for stimulation optimization. One of the screening nights will be extended to screen for sleep apnea and periodic limb movements during sleep using an ambulatory screening device. Upon final inclusion, 24 PD and 24 MCI patients will be enrolled in the study for an overall period of 6-8 weeks (not including screening phase). Patients will receive 2 weeks of auditory SWS enhancement and 2 weeks of sham stimulation (only device application, no tones played) in a counter-balanced cross-over design, with a 2-4 week washout period during cross-over. Study visits will be performed immediately before and after each intervention period, i.e. after 2 weeks of auditory stimulation or sham stimulation, respectively. Study visits will include standardized clinical examinations, symptom questionnaires, blood sampling after intervention and screening for adverse events by a study physician. Study visits will take place at the Department of Neurology, University Hospital Zurich. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
