Feasibility and Efficacy of rTMS in Depression in Patients With Autism Spectrum Disorder (ASD)

Depression is a common complication of Autism Spectrum Disorder (ASD): it is four times more prevalent in people with ASD than in the general population. However, treating depression in people with ASD is complicated by the lack of guidelines. Antidepressants appear to be less effective and less well tolerated than in the general population. rTMS (repetitive transcranial magnetic stimulation) is a technique that stimulates the brain in a painless and non-invasive way. This technique is well tolerated and has very few side effects (headaches, fatigue). It is now used routinely in clinical practice to treat resistant depression, with satisfactory results. A few studies using rTMS in depression in people with ASD have shown encouraging results and avenues for improvement. It could therefore be interesting to conduct a therapeutic study with rTMS on depression in people with ASD, following the avenues for improvement proposed by previous studies. The main objective is to evaluate the effectiveness of rTMS in depressed patients with ASD by looking at changes in mood before and after treatment. The investigator will also look at the effects on executive and attentional functions and repetitive behaviors, as well as treatment tolerance.
