(WTVM) - Brain scans may give doctors a clearer picture on how to treat people with depression.
A new study in the Journal of the American Medical Association finds patients who show a lot of activity in a certain part of the brain are more likely to benefit from antidepressants. However, people who have low activity in that area are better off with psychotherapy.
Researchers say if the finds are confirmed, the scans could play an important role in the treatment of depression.
A second, independent study finds severe depression and other mood disorders may be linked to infections.
Danish researchers followed 90,000 people for more than 50 years and they found those who were treated for an infection were at a higher risk of being diagnosed with a mood disorder.
Scientists believe that stress on the immune system may affect the brain.
