A Multifocal TDCS-EEG Protocol for Improving Symptoms of Mild Cognitive Impairment and Early Dementia

Real multifocal tDCS will be delivered with an intensity of 2.0 mA over 8 electrodes positioned over the frontal and temporal areas in the left hemisphere according to the international 10/10 EEG system. The overall duration of stimulation will be set at 20 minutes.

Sham multifocal tDCS will be delivered with an intensity of 2.0 mA over 8 electrodes positioned over the frontal and temporal areas in the left hemisphere according to the international 10/10 EEG system. The overall duration of stimulation will be set at 30 seconds.

During the two cycles, all participants will undergo traditional cognitive stimulation therapy, involving paper-and-pencil exercise and computerised activity on several cognitive domains including memory, attention, and executive functions (duration 30-40 minutes) .
