Functional MRI studies suggest that psychotherapy for PTSD improves symptoms by changing the way brain networks communicate with each other, offering a potential “biosignature” for effective treatment
In prior blog posts we have reviewed literature demonstrating that TBI and PTSD may not be separable but may, in fact, be intimately related not just at the level of symptoms and etiology, but also as the level of pathophysiology. Both can impact the interactions between the body’s immune, endocrine and neuromodulatory neurotransmitter systems. Read More

A topic frequently addressed in this blog is the building body of evidence showing that the minority of patients who have long term, sometimes permanent, symptoms following concussion typically experience those symptoms because of injury to the brain, not to achieve some “secondary gain.” Although scientists do not have a clear understanding about why some people are more vulnerable to these injuries, we know as discussed in prior posts, that certain factors can play a role, such as genetics, prior head injuries and a history of migraines. Two recently published studies contribute to our understanding that real pathology likely underlies most persistent symptoms and that this pathology can be identified with advanced neuroimaging techniques.

Using functional brain imaging (fMRI) a multidisciplinary team of researchers at the University of Buffalo have documented metabolic and physiologic changes in the brains of patients experiencing post-concussion symptoms. They found improvements in both imaging findings and in patient symptoms following a controlled, progressive aerobic exercise program. The results have been published in both the Journal of Head Trauma Rehabilitation and in Current Sports Medicine Reports and are summarized in UB news releases. Read More
