Eligibility Criteria
Inclusion Criteria:
- PD: Diagnosis of PD along international criteria, with mild to moderate disease severity (Hoehn and Yahr scale, stages ll-lll)
- PD: Ability to apply the intervention for the duration of study
- MCI: Diagnosis of MCI along international criteria, with a predominant amnestic presentation (single- or multi-domain amnestic MCI)
- MCI: Presence of a cohabitant person who could assist with the application
- MCI: Ability to apply the intervention for the duration of study, with assistance of co-habitant if needed
PD and MCI:
- Age above 18 years
- Informed consent as documented by signature
- Stable home situation (e.g. long-term place to live) that allows for reliable application of intervention for the duration of the study
- Sufficient German language comprehension to follow the study procedures and answer all questions related to the study outcomes
- Dosing of dopaminergic, cholinergic, and other PD or MCI medication must have been stable for at least 14 days prior to start of the first intervention
- Negative pregnancy test during screening (except in women who are surgically sterilized/hysterectomized or postmenopausal for longer than 1 year)
Exclusion Criteria:
- PD: Presence of neurologic, psychiatric, or sleep disorders (others than associated with PD)
- PD: Parkinsonism without response to levodopa; Atypical Parkinsonian syndromes
- PD: Cognitive impairment (Montréal Cognitive Assessment [MoCA] <24)
- MCI: Present diagnosis of a neurological (other than MCI) or interfering psychiatric disease or sleep disorder (e.g. sleep apnoea syndrome, restless legs syndrome)
PD and MCI:
- Severe medical conditions as renal insufficiency, liver failure or congestive heart failure
- Regular use of the following drugs: Benzodiazepines and other central nervous system (CNS)-depressant substances, melatonin and other sleep inducing substances, approved drugs for Alzheimer-type dementia (acetylcholine-esterase inhibitor, memantine)
- Inability to hear the tones produced by the TSB Axo
- Skin disorders/problems/allergies in face/ear area that could worsen with electrode application

- Participation in another study with investigational drug or investigational medical devices within the 30 days preceding and during the present study
- Previous enrolment in the current study
- Enrolment of the investigator, his/her family members, employees and other dependent persons
- Shift work (work during the night)
- Travelling more than 2 time zones in the last month before intervention starts or during intervention (start of intervention will be adapted to fit with this criteria)

- High caffeine consumption (> 5 servings/day; including coffee, energy drink)
- Implanted deep brain stimulation electrodes
- Women who are pregnant or breast feeding
- Intention to become pregnant during the course of the study
- Lack of safe contraception, defined as: Female patients of childbearing potential, not using and not willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or who are not using any other method considered sufficiently reliable by the investigator in individual cases

The device records EEG and other biosignals throughout the night and scans these signals for slow waves associated with deep Non-Rapid Eye Movement (NREM) sleep. Upon recognition of such slow waves and fulfilment of other criteria, a tone is played via the headphones to stimulate and enhance slow waves without waking up the patient.
Playing no tones during NREM sleep but wearing the device and recording the biosignals over a period of 2 weeks, every night.
