Comparing 6 approaches for dementia
Official title: Longitudinal Study to Investigate Different Transcranial Electrical Stimulation
Longitudinal Study to Investigate Different Treatment Protocols of Transcranial Electrical Stimulation for Individuals With Dementia
Interventions
Transcranial Direct Current Stimulation (tDCS)
A light electrical current with zero frequency (tDCS) will be applied to the scalp of the participants via 2 electrodes, while the participants perform cognitive exercises with the guidance of a trained research assistant. They have the option of having their choice of music playing in the background while they perform the cognitive exercises. Cognitive exercises: Participants will perform memory and learning games/tasks through the "Mind Triggers" app on an IPad and other cognitive games. Participants will be guided by a highly trained research assistant.
30 Hz Transcranial Alternating Current Stimulation (tACS)
A light electrical current with 30 Hz frequency (tACS) will be applied to the scalp of the participants via 2 electrodes, while the participants perform cognitive exercises with the guidance of a trained research assistant. They have the option of having their choice of music playing in the background while they perform the cognitive exercises. Cognitive exercises: Participants will perform memory and learning games/tasks through the "Mind Triggers" app on an IPad and other cognitive games. Participants will be guided by a highly trained research assistant.
50 Hz Transcranial Alternating Current Stimulation (tACS)
A light electrical current with 50 Hz frequency (tACS) will be applied to the scalp of the participants via 2 electrodes, while the participants perform cognitive exercises with the guidance of a trained research assistant. They have the option of having their choice of music playing in the background while they perform the cognitive exercises. Cognitive exercises: Participants will perform memory and learning games/tasks through the "Mind Triggers" app on an IPad and other cognitive games. Participants will be guided by a highly trained research assistant.
70 Hz Transcranial Alternating Current Stimulation (tACS)

About This Trial
This research investigates the effect of different frequencies of tACS (0 Hz, 30 Hz, 50 Hz, 70 Hz, 90 Hz) and tRNS with cognitive exercises in a regimen protocol of 4 weeks, everyday (Monday to Friday). The study design is a longitudinal study design in which participants receive different tES randomly ordered. Treatments occur for 4 weeks, then 12 weeks of no treatment (wash-out period), repeated for each tES treatment type. Participants have the option of having their choice of music in the background while they perform cognitive exercises.
