Purpose

The purpose of this project is to evaluate the preliminary effects of home-based M1-SO applied tDCS (that is, tDCS with the anode over the primary motor cortex and the cathode over the contralateral supraorbital area) on clinical pain in persons with early-stage Alzheimer's disease and Related Dementias (ADRD), to evaluate the preliminary effects of home-based M1-SO applied tDCS on pain-related cortical response in persons with early-stage ADRD, and to evaluate the feasibility and acceptability of home-based M1-SO applied tDCS for pain management in persons with early-stage AD.

Experimental
Active tDCS
  • Device: Active tDCS
    tDCS with a constant current intensity of 2 milliampere (mA) will be applied for 20 minutes per session daily for 5 days via the Soterix 1x1 tDCS mini-CT Stimulator device with headgear and 5x7 cm saline-soaked surface sponge electrodes.
Placebo Comparator
Sham tDCS
  • Device: Sham tDCS
    The electrodes will be placed in the same positions as for active stimulation, but the stimulator will only deliver 2 mA current for 30 seconds.
