Brief Summary
Grounding (Earthing) refers to the practice of contacting the Earth or a properly installed grounding mat with the body. Previous studies on grounding have shown positive effects body-wide inflammation, acute and chronic pain, and immune system response. Prior studies on the inflammatory process of mild cognitive impairment due to Alzheimer's disease, Alzheimer's disease, and some other dementias have shown connections between immune system dysregulation, inflammatory markers, and severe disease progression. Finding ways to mitigate or turn off the inflammatory response is key to treating mild cognitive impairment due to Alzheimer's disease. The purpose of this study is to evaluate the effects of sleeping grounded on cognition and personal perceptions in participants with a diagnosis of mild cognitive impairment due to Alzheimer's disease as evidenced by a battery of assessments using Cogstate's Cognitive Brief Battery and a qualitative questionnaire. We hypothesize that assessment scores will improve with grounding and that perceptions will positively correlate with an increase in scores. Modulation of risk factors like glucocorticoid resistance, SCI, and immune system dysfunction through grounding may lead to an accessible, natural technique for neurodegenerative disease prevention or treatment.

Primary Outcomes (40)
Baseline Psychomotor Function Score
In this simple reaction time Detection test, a playing card is presented face-down in the center of the screen. After a random interval, the card will turn over so that is it face-up (revealing a Joker card - this same card is used throughout the test). The subject is asked to press the "YES" button as soon as the card turns face-up. Assessed at baseline then weekly for three weeks.

Eligibility Criteria
You may qualify if:
- All approved participants must
- Be at least 55 years of age; all genders and ethnicities;
- Have English as their primary language or be able to speak, read, and write English fluently; As this is a vulnerable population, this investigator must be able to evaluate understanding and cannot reliably do that with someone who is not fluent in English;
- Have a current diagnosis of mild cognitive impairment due to Alzheimer's disease made by a medical doctor;
- Be able to spend at least 6 hours per 24-hour period sleeping or resting on the grounded mat;
- Be able to legally consent to participating in this study;
- Agree to allow the researcher to come into their home to setup the equipment and administer the tests;
- Be able to see well enough to use a laptop to complete electronic testing;
- Be alert and oriented X 4 based on initial verbal screening and in-person visits;
- Reside in or around the Greater Austin, Texas, area/Central Texas area;
- Sleep in a dwelling that is grounded.
You may not qualify if:
- All approved participants must
- Not have a diagnosis or conversion to AD or any other type of memory disorder before or during the study period including but not limited to dementia, Lewy body disease, Creutzfeldt-Jakob disease, Parkinson's disease, Huntington's disease, vascular cognitive impairment, frontotemporal dementias, primary progressive aphasia, autoimmune encephalopathy, and normal pressure hydrocephalus;
- Not have a diagnosis of stable MCI;
- Not have any prior diagnosis of traumatic brain injury;
- Not have any history of grounding consistently for more than 60 minutes/day in the past year. This includes natural methods and the use of any grounding devices;
- Not have any in-the-moment assessment that leads the investigator to believe that the participant is not fully aware or does not understand what is being asked of them. Again, this is a vulnerable population, and I will exclude or cut any participant who shows signs of confusion;
- Not be taking or have taken in the previous 30 days any of the following medications:
- daily anti-inflammatories, prescription or over the counter;
- blood pressure medications (anti-hypertensives);
- blood thinners (anti-coagulants);
- e. glucose control medications; f. thyroid medications; g. anti-convulsive medications (no matter the diagnosis); h. any type of monoclonal antibody; i. any type of immunosuppressive, including steroids; j. any type of immunomodulator.
- Inability to answer the questions in the initial screening interview;
- Inability to follow instructions.
