Post-concussion Depression and Anxiety linked to Brain Injury Patterns

This might be an important study that could help addicts receive improved care based on a better understanding of these common disorders.

If we can continue to understand how brain injury affects moods, we can help people who are self-medicating get the treatment they might need after things like car accidents, football concussions, domestic abuse, drunken brawls, etc., and thus saving the lives that may be lost to suicide brought on by depression.

A new MRI study has found distinct injury patterns in the brains of people with concussion-related depression and anxiety, according to a new study published online in the journal Radiology. The findings may lead the way to improved treatment and understanding of these common disorders, researchers said.

Post-concussion psychiatric disorders like depression, anxiety and irritability can be extremely disabling for those among the nearly 3.8 million people in the United States who suffer concussions every year. The mechanisms underlying these changes after concussion—also known as mild traumatic brain injury—are not sufficiently understood, and conventional MRI results in most of these patients are normal.

For the new study, researchers from the University of Pittsburgh Medical Center (UPMC) in Pittsburgh used diffusion tensor imaging (DTI), an MRI technique that measures the integrity of white matter—the brain’s signal-transmitting nerve fibers—to see if injuries to the nerves may be the root cause of these post-traumatic depression and anxiety symptoms.

The researchers obtained DTI and neurocognitive testing results for 45 post-concussion patients, including 38 with irritability, 32 with depression and 18 with anxiety, and compared the results with those of 29 post-concussion patients who had no neuropsychiatric symptoms.
