Could a Head-Zap at home boost your brain?

This study tested whether a gentle, non-invasive brain stimulation technique (tDCS) done at home, along with computer-based brain games, could improve thinking and language skills in people with primary progressive aphasia, mild cognitive impairment, or dementia. Participants used a headset to stimulate a key brain area while doing cognitive exercises. The study aimed to see if this approach could ease symptoms like memory loss and language difficulties.
