Personalized Non-invasive Neuromodulation by rTMS for Chronic and Treatment Resistant Catatonia - A Proof of Concept Study

Investigators hypothesize that personalizing rTMS targets using functional MRI will allow to improve symptoms of patients suffering from chronic catatonia.

Study Overview

Detailed Description

Two dysfunctional networks or regions will be chosen (verum 1 and 2) based on their abnormal rCBF. In line with the symptoms, dorso-lateral prefrontal and premotor regions are expected to be chiefly concerned. A normal region regarding its rCBF will be used as placebo. Targets will be stimulated using intermittent or continuous theta-burst according to the rCBF anomaly as an attempt to "normalize" their activity. The coil will be positioned using a robotic device under the control of a neuronavigation system in order to deliver a homogeneous stimulation. Using a balanced blinded randomized cross-over design, patients will be stimulated on 5 consecutive days (4 sessions per day) and evaluated pre-, post-stimulation and 1 month after. In this pilot study the primary outcome measures will be the clinical global impression scale whereas MRI will insure that stimulations achieved the correction of the rCBF anomalies. Secondary outcome measures will include personalized target symptom scales, and scales for catatonic, apathic and obsessive-compulsive symptoms.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Verum 1 - Premotor

The target region will be defined by comparing the rCBF scan of the patient to a control population (n = 38). rCBF will be measured using the QUIPS2 arterial spin labeling sequence on a Siemens 3T Verio.

The network including the premotor region will be targeted. The therapeutic protocol will be design to correct the rCBF anomaly.

To increase cortical rCBF, iTB (intermittent theta burst) will be used: triplet at 50 Hz repeated at 5 Hz in trains of 2 sec with an inter-train interval of 8 sec.

To decrease cortical rCBF, cTB (continuous theta burst) will be used: triplet at 50 Hz repeated at 5 Hz in trains of 40 sec. Intensity 120% of passive threshold (or 150% of active threshold).

Stimulation protocol will be used up to 5 times per session to allow a reasonable regional or network coverage.

Patients will have 4 sessions per day on 5 successive days per arm.
