About this trial
The goal of this clinical trial is to learn about the ability of non-invasive brain stimulation during sleep to enhance people's deep sleep and its potential benefit on memory in people with mild cognitive impairment via home use sleep therapy device (SleepWISP) as well as learn about biomarkers associated with Alzheimer disease (AD). The clinical trial aims to answer the following main questions:
1. Whether the non-invasive transcranial electrical stimulation (TES) delivered by SleepWISP could provide short-term enhancement of deep sleep in a single night in the target population. 2. Whether TES delivered by SleepWISP could enhance deep sleep over multiple nights in the target population. 3. Whether enhance on deep sleep could improve memory performance in the target population.
Participants will be asked to wear non-invasive and painless devices that record their brain activity during sleep along with an actigraphy watch that measures their movement throughout the day. In addition, blood samples or nasal swab assays will be collected from participants multiple times during the study.

Trial outcomes
Primary outcomes
Device Usability
Criteria for success: the prototype is safe for all participants, and it is usable at home by 80% of adults with MCI. Specific outcome ratings (5-point Lickert scale) will be obtained for (1) ability to clean the device, (2) ability to apply the device, (3) ability to turn on the tablet (launching the dedicated software); (4) ability to start treatment; (5) ability to complete treatment.

Secondary outcomes
Memory Performance; Paired-Associates Verbal Learning (PAVL)
10 pairs of unrelated, neutral-valence nouns are learned each night before sleep. Participants are tested in the morning when an online program provides the first word of the pair and they type in the second word that went with it (cued recall). More accurately recalled pairs of words (0-10 pairs) indicates better memory performance.
Beck Depression Inventory (BDI)
Assessment of psychiatric symptomatology; 21-item self-reported inventory that measures symptoms of depression. Responses are weighted and a higher score (1-40) indicates higher levels of depression.
Beta Amyloid Excretion Blood Sample or Nasal Swab Assay
Collected for exploratory analysis on biomarkers associated with Alzheimer's disease and treated with an anticoagulant, plasma isolated and stored at -80 until Aβ detection. Aβ40 and 42 detection will be performed using a commercially-available immunoassay (Innotest, Fugirebio).
