Home-based deep sleep modulation in Parkinson's disease: extension study on long-term feasibility and sleep-related outcomes.

This study assessed feasibility and effects of a randomised two-week, at-home intervention with phase-targeted auditory stimulation (PTAS) of slow waves in Parkinson's disease (PD). We reproduced previously reported enhancement of slow wave activity and confirmed indications of improved patient-reported outcomes. Together with the high adherence and data quality, this suggests that home-based PTAS protocols are a feasible method for investigating the long-term therapeutic potential of deep sleep enhancement in PD.
