tDCS Effect on Psychotic Symptoms in Dementia With Lewy Bodies (DLB), and Impacts on Caregiver Burden

Source: ClinicalTrials.gov · Last updated 13 Oct 2026

Brief summary (registry, in English)

The goal of this pilot prospective study is to evaluate the effect of tDCS on psychotic-like symptoms in patients with Lewy Body Dementia (LBD). The main questions it aims to answer are: * What is the effect of tDCS on neuropsychiatric symptoms, especially psychotic-like symptoms? * What is the impact of tDCS on caregiver burden? Researchers will compare active tDCS (2mA stimulation, anode on the left dorsolateral prefrontal cortex, cathode on the right fronto-orbital) to Sham tDCS (placebo stimulation, no intensity applied) to see if there is an effect on reducing psychotic-like symptoms and on caregiver burden. Participants will: * Undergo a stimulation phase consisting of 10 tDCS sessions of 20 minutes each, spread over 2 consecutive weeks (5 days with stimulation, 2 days without stimulation, 5 days with stimulation). * perform assessments at T0 (inclusion), T1 (at the end of the stimulation phase), and T2 (follow-up at 8 weeks post stimulation).
