Comparison of Targeting Methods for Transcranial Magnetic Stimulation Treatment of Depression

Официальное название

Evaluating the Effectiveness of Different Targeting Approaches for Transcranial Magnetic Stimulation Treatment of Depression

Обзор

We aim to learn whether use of a mixed reality device for transcranial magnetic stimulation (TMS) targeting can improve treatment outcomes compared to targeting through scalp measurements or a commercial neuronavigation system. Prior studies indicate that neuronavigation can lead to improved treatment outcomes compared to scalp measurements, but neuronavigation adaption has been lacking due to the increased burden of the neuronavigation setup on the TMS operator. We will assess whether use of a mixed reality device can decrease that burden and speed up the neuronavigation process and is feasible to be used in a clinical setting.

Подробное описание

Prior studies suggest that treatment efficacy for TMS treatment of depression is affected by the targeting method used to guide TMS coil placement. We will compare the treatment outcome for three patient groups. TMS coil placement is guided for group 1) with simple scalp measurement targeting, for group 2) with a mixed reality neuronavigation system.

The treatment schedule for the medically prescribed TMS treatment for each patient are 30 daily weekday repetitive TMS treatments for 6 weeks with an additional 6 treatments tapered over 3 weeks.

Вмешательства

• Устройство Transcranial Magnetic Simulation
  Brain stimulation treatment will be performed using FDA-cleared TMS coils according to their intended use of treatment of medication resistant depression by targeting the dorsolateral prefrontal cortex.
• Устройство Mixed reality neuronavigation
  Targeting of the dorsolateral prefrontal cortex will be performed with the help of a mixed reality neuronavigation system.

Критерии участия

Критерии включения

• Male or female subjects ages 18-75.
• MRI scanning eligibility, including no evidence of any form of metal embedded in the body (e.g., metal wires, nuts, bolts, screws, plates, sutures), as these produce artifacts when brain imaging. All potential subjects for the MRI component will need to successfully complete the screening forms at the Stanford Center for Cognitive and Neurobiological Imaging (CNI) or the Lucas Center. Those subjects who present no contraindications to being scanned will be allowed to participate.
• Healthy subjects with no history of any Axis I psychiatric disorder, are taking psychotropic medication, or use illicit drugs.
• Clinical subjects with a diagnosis of treatment resistant depression and prescribed a clinical course of treatment with rTMS.

Критерии исключения

• Any contraindication to being scanned in the 3.0T scanner at the Lucas Center or CNI such as having a pacemaker or implanted device that has not been cleared for scanning at 3.0 Tesla.
• History of neurological disorders including but not limited to brain surgery, deep brain stimulation, radiation treatment, brain hemorrhage or tumor, stroke, seizures or epilepsy, head trauma.
