Head Injuries may cause mental illness

Previous studies have shown that head injury induces inflammation in the brain, which causes several changes. Check out this study from University of Copenhagen. They studied 113,906 people who had been hospitalized for head injuries over a 23-year period.

Previous studies have shown that head injury induces inflammation in the brain, which causes several changes—for example, an increased permeability of the blood-brain barrier. Normally the barrier protects the brain from potentially harmful contents in the bloodstream, but injury-induced inflammation may allow these substances access to the brain.

“For some individuals, this might initiate damaging processes in the brain,” Dr. Orlovska says.
Early detection can help improve the prognosis for mental illness, so Dr. Orlovska also recommends seeing a doctor as soon as any symptoms appear.
