The Effects of Transcranial Direct Current Stimulation (tDCS) in Older Lonely Individuals

This study will deliver tDCS sessions for ten sessions completed within two weeks. Consecutive tDCS sessions are separated by at least 24 hours. Participants assigned to one of the two experimental groups will receive 20 minutes of active stimulation with a 2mA intensity over the corresponding brain regions.

This study will deliver tDCS sessions for ten sessions completed within two weeks. Consecutive tDCS sessions are separated by at least 24 hours. Participants assigned to the sham control group will receive 30 seconds of active stimulation over brain regions identical to either the left DLPFC or the right VLPFC experimental tDCS group.
