When traumatic brain injuries TBI cause psychiatric symptoms
In 2013, a group of Danish scientists found that individuals with TBI (including concussions) were
four times more likely to develop a mental illness. People who had received a TBI were
65 percent more likely to develop schizophrenia,
59 percent more likely to develop depression and
28 percent more likely to develop bipolar disorder.
This study is the largest of its kind and involved following 1.4 million Danish citizens born between the years 1977 and 2000.
This study is far from the only one to suggest a link between TBI and mental illness. A research team led by Jonathan Godbout, an associate professor at Ohio State University,found that mice that had sustained a TBI demonstrated increased depressive symptoms as well as higher-than-normal levels of neural inflammation. (I have previously written aboutmental illness’ surprising link to inflammation). Yet another study found that experiencing depressive symptoms after a head injury is more common than not — the prevalence of depression after TBI is greater than 50 percent.
The most frightening piece of research, however, was published earlier this year: People who had received a concussion in the past were three times more likely to fall victim to suicide.
