Deep rTMS Modulating Insula Synaptic Density and Smoking Behavior in Schizophrenia
Purpose of the study: Evaluate the effect of deep repetitive transcranial magnetic stimulation (deep rTMS; hereafter abbreviated as "dTMS") on synaptic density measured with positron emission tomography (PET) and the radiotracer [11C]UCB-J. We also seek to link plasticity changes in the regions targeted by the electric field (especially, the insula) to changes in the functioning of insula circuits and behavioral cigarette usage in patients with schizophrenia (SCZ).
Importance of the study: This is the first study designed to directly evaluate the mechanism of action (MOA) of dTMS for smoking disruption in patients with SCZ. Patients with SCZ are a vulnerable population in high, immediate need of new smoking therapeutics for reducing premature morbidity and mortality.

Contraindications to dTMS*
- The FDA website currently states that the Brainsway device used in this study is contraindicated for patients who have "metallic objects or implanted stimulator devices in or near the head, including cochlear implants, deep brain stimulators, vagus nerve stimulators, other implanted electrodes or stimulators, aneurysm clips or coils, stents, bullet fragments, jewelry and hair barrettes." We will monitor the FDA guidelines and implement any changes to the inclusion/exclusion criteria based on their most updated recommendations.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Active deep transcranial magnetic stimulation (dTMS)
Each treatment consists of 60 trains, each lasting 3 sec and interleaved with a 15 sec delay.
The entire treatment is delivered over 20 min.
The treatment goes for 5 days/week and for a total of 3 weeks.
|
First, we find the position of the right abductor pollicis brevis (APB) motor cortex, finding the minimal motor threshold (MT) required for its activation, which determines the strength of the pulses.
After determining the MT, dTMS stimulation is applied 6 cm anterior to the motor "hot spot", at 120% of the MT.
The target threshold is built toward gradually.
During the first treatment, participants receive stimulation at 100% of the MT.
During the second treatment, stimulation intensity increases to 110% of the MT.
Beginning at the third treatment and continuing onward, participants receive treatment at 120% of the MT for the course of the treatment.

SHAM_COMPARATOR: Sham
Active and sham cards do not differ in appearance, and both coils are enclosed within the same helmet, enabling double-blind administration.
The same procedure will be done, the only difference is that the sham card does not deliver any stimulation.
|
Sham group will go through the same procedure.
The only difference is that the sham card does not deliver stimulation.
