Condition: Post Traumatic Stress Disorder · Sponsor: Andrew Nicholson
Post-traumatic stress disorder (PTSD) is a debilitating and highly prevalent psychiatric disorder that develops in the aftermath of trauma exposure (APA, 2013). PTSD has been strongly associated with altered activation patterns within several large-scale brain networks and, as such, it has been suggested that normalizing pathological brain activation may be an effective treatment approach. The objective of this proposed study is to investigate the ability of PTSD patients to self-regulate aberrant neural circuitry associated with PTSD psychopathology using real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback. Here, the investigators are building upon previous single-session pilot studies examining the regulation of the amygdala and the posterior cingulate cortex (PCC) in PTSD (Nicholson et al., 2021) (Nicholson et al., 2016) by: (1) Examining the effect of multiple sessions of rt-fMRI neurofeedback and, (2) Comparing PCC- and amygdala-targeted rt-fMRI neurofeedback to sham-control groups with regards to changes in PTSD symptoms and neural connectivity.
