Multimodal Image Analysis and Guidance of Neuromodulation for Trauma-Related Symptoms
University of New Mexico
Summary
MAGNETS is a prospective, randomized, parallel-design, sham-controlled clinical trial of accelerated, functional magnetic resonance imaging (fMRI)-guided intermittent theta burst stimulation (iTBS) to the right dorsolateral prefrontal cortex (dlPFC) for chronic symptoms of posttraumatic stress disorder (PTSD) in a comorbid Veteran population.
Description
In MAGNETS, sixty-four participants will be recruited from the NMVAHCS PTSD programs, Polytrauma services, and outpatient mental health clinics. At study entry (Visit #1), participants will undergo baseline demographic, behavioral, and cognitive assessment, and fMRI and diffusion tensor imaging (DTI). The data analysis team will then determine the image-based target in the right hemisphere. Participants will be randomized to either the active (n=32) or sham (n=32) group and undergo 50 sessions of iTBS (10x/day, five days). At end of treatment (Visit #2), they will repeat all baseline tests, in…

Inclusion Criteria: * Veterans will be enrolled in this study if they: 1. are aged 18-80; 2. have a documented diagnosis of PTSD with evidence of ongoing symptoms as demonstrated by score of "31" or higher on the PCL-5, a measure of posttraumatic stress symptoms; 3. are fluent in English (as the neuropsychological testing tools used are only available in English) and 4. have been on stable doses of psychotropic medications for the past month.

- DeviceActive Intermittent theta burst stimulation
Intermittent theta burst stimulation (iTBS) is an efficient form of transcranial magnetic stimulation that allows up to 10x more pulses to be delivered in a given timeframe compared to conventional stimulation patterns.
