Overview
Brief Summary
This is a monocentric prospective, randomized, double-blind placebo-controlled study. It is designed to evaluate the superiority of the rTMS over sham treatment of depressive symptoms in the context of dementia. It is aimed at a population ≥ 65 years old, with affective BPSD. We wish to recruit 44 participants, with an estimated rate of potential drop out of 20%. Patients will be randomly assigned to the sham or rTMS group. The sham stimulation reproduces the procedure in all the steps, has the same duration and differs exclusively by the device setting. After inclusion, both groups will receive 15 sessions distributed over 5 days a week for 3 weeks
