Adults who experienced physical or sexual abuse in their lifetime have a higher risk of developing ulcerative colitis (UC).

Autism treatment fads keep cropping up even after science has proved them unworthy. Now, researchers from Emory Health Sciences may have figured out why.

Researchers from Northwestern University have suggested that many mental disorders do not appear to predict future violent behavior, with the exception of substance use disorders.

Immigrant populations tend to have nearly 2 times the prevalence of psychotic disorders compared to the general population of the host country.

A growing trend in the medical community is the use of a technique known as mindfulness based stress reduction. While the results have shown to be inconclusive in the treatment of multiple sclerosis there is work being done to show its efficacy in helping patients.
