A recent study clarified how cognitive behavioral therapy improves symptoms of depression and post-traumatic stress disorder (PTSD). The participants were 62 adult women. One group had depression, one had PTSD, and the third was made up of healthy volunteers. None were taking medication at the time of the study. The researchers, led by Yvette Shelive, used functional magnetic resonance imaging (fMRI) to analyze participants’ amygdala connectivity.

At the start of the study, participants with depression or PTSD showed diminished connectivity between the amygdala and brain areas related to cognitive control, the process by which the brain can vary behavior and how it processes information in the moment based on current goals. The lack of connectivity reflected the severity of the participants’ depression. Twelve weeks of cognitive behavioral therapy improved mood and connectivity between the amygdala and these control regions, including the dorsolateral prefrontal cortex and the inferior frontal cortex. These regions also allow for executive functioning, which includes planning, implementation, and focus.
