Link discovered between soldier depression, brain injury


Researchers have made a breakthrough on why some soldiers become depressed, and the new information could lead to better treatment, not only for members of the military, but the general public as well.

The research suggests that depression is caused by brain disruptions caused by head injuries.

Scientists at Walter Reed National Military Center used MRIs to scan 130 soldiers with traumatic brain injuries.

They found that brain circuits connected to emotional control were disrupted in patients with depression.

Experts say the findings could lead to new treatments for injury-related mood disorders.
