Summary
This trial is testing a new method called transcranial direct current stimulation (tDCS) to help people with Lewy body dementias (LBD). LBD patients often have trouble staying alert, and this treatment uses a small electrical current to stimulate certain brain areas. The goal is to see if this can improve their alertness and reduce cognitive issues. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has been found to enhance cognitive functions in various neurological conditions, including Alzheimer's disease and mild cognitive impairment.
Who is the study for?
This trial is for individuals with Lewy body dementias, specifically those diagnosed with probable DLB or PDD who experience cognitive fluctuations. Participants must be on stable doses of cholinesterase inhibitors for at least four weeks and exhibit certain symptoms like motor signs, attention issues, visual hallucinations, sleep disturbances, smell dysfunction, or autonomic problems.
What is being tested?
The study aims to understand the role of acetylcholine in alertness fluctuations in dementia patients and assesses the potential benefits of HD-tDCS (high-definition transcranial direct current stimulation), a non-invasive brain stimulation technique targeting specific brain regions associated with alertness.
What are the potential side effects?
While not explicitly stated here, common side effects of HD-tDCS may include mild itching, tingling or discomfort at the site of electrode placement during stimulation. There might also be temporary headaches or lightheadedness post-treatment.
