Sample size (n=10) is convenient and designed to explore acceptability and feasibility. Participants who are enrolled will be provided a tDCS device to use for a period of four weeks. They will have two study visits, baseline (BL) and the 4th week visit (W4). During each visit participants will answer various questionnaires to assess patient-reported outcomes such as sleep quality, cognitive impairment, depression, anxiety, fatigue, and user acceptability.~The entire cohort will receive a transcranial direct stimulation (tDCS) device which uses LIFTiD Neurostimulation technology (RPW TECHNOLOGY, LLC, New York, USA). Participants will take the device home and daily, they will use the device for a maximum of 20 minutes to stimulate neuroplasticity. During the stimulation period they will be asked to perform a light activity such as reading, checking emails, etc. The participants will return to the McNair Campus for their final visit after 4 weeks.
Cognitive impairment refers to when an individual struggles to learn, concentrate, remember, or make decisions. This can be due to underlying neurological diseases (i.e. Alzheimer's disease, dementia, etc.), caused by viral illness (i.e. brain fog experienced by COVID-19 survivors) or physical trauma (i.e. concussion). Recent reports indicate that two out of three Americans experience some amount of cognitive impairment in their lifetime.~There are a number of therapies that have been used to help address this condition. One of these is transcranial direct current stimulation (tDCS), which delivers sustained direct current to to the head area via electrodes. A number of studies have indicated that this form of therapy is safe and efficacious at inducing neuroplasticity and exciting neuronal activity. These factors can help improve aspects of cognitive functioning such as working memory, learning, and task performance.~The purpose of this pilot study is to examine the acceptability and proof of concept effectiveness of a wireless, transcranial direct current stimulation for people with cognitive impairments.
