NCT05524233
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.
