This study is looking at how tDCS (transcranial direct current stimulation) might help people with Lewy Body Dementia (LBD). LBD is a brain condition that can cause memory problems and symptoms like seeing things that aren't there (psychotic-like symptoms). The study will also see how tDCS affects the stress levels of family members who take care of these patients. There are two groups: one gets real tDCS, and the other gets a fake version (sham) to compare results. Each participant will have 10 sessions of tDCS over two weeks, and there will be follow-ups to check on their progress.

• The study lasts for a total of 10 days of treatment spread over two weeks.
• Participants must have a family member who can help with the study.
• No payment or risks like changes in medication are mentioned.
