Prevention of Alzheimer's Disease With CR Plus tDCS in Mild Cognitive Impairment and Depression (PACt-MD)

"First, the intervention sessions will be administered 5 days/week for 8 weeks (induction phase). Then, for 5 days once every 6 months (consolidation phase).~tDCS session: anode over Fz \& cathode over Iz; direct current: 2 mA (current density=0.57A/m2) for 30 min. at the beginning of each group session.~Cognitive Remediation (CR) will also be administered. Sessions last 2 hours each day in a group supervised by trained interventionists. Participants will also complete CR exercises online at home. CR will consist of computer-based exercises relevant to attention, processing speed, executive function, and verbal and working memory with titrated difficulty levels. Performance feedback will reinforce progress. Strategic monitoring and bridging discussions will promote transfer of cognitive gains to everyday tasks.~During COVID-19, booster sessions can be provided either in-person or virtually (except for tDCS that cannot be done remotely)."
