Study 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

Exclusion Criteria:

Study arms

  • Active comparator
    Active

    Magnetic stimulus intensity of 80% of the motor threshold applied at the frequency of 20 Hz over the left DLPFC with a total number of pulses of 1200 / treatment session for a total of 5 sessions /week for 3 consecutive weeks

    Device: rTMS

  • Placebo comparator
    Sham

    Sham procedure implies the use of a "sham" coil of exactly the same dimension and appearance as the one used for the effective treatment. This sham coil is made for research purposes by the producing company and used in accordance with the instructions for use, which explicitly mention it (cf. instruction manual page 34: Stimulation Coil DuoMAG 70BFP (70BFP1, 70BFP2), typical use for blinded studies).

    Device: rTMS

Interventions

  • DevicerTMS

    The stimulus intensity will be 80% of the motor threshold and the frequency will be 20 Hz for all patients. The total number of pulses will be 1200 for a single treatment session. We plan a total of 15 sessions distributed over 5 days a week for 3 consecutive weeks.
