Man's head
Statistics show one in every five college-aged American suffers a personality disorder, interfering with his/her everyday life routine.

According to a study published in the Archives of General Psychiatry, mental disorders including obsessive compulsive, anti-social and paranoid behavior are seen in 25 percent of college-aged Americans for which only a small group receive necessary treatment.

The study revealed that nearly half of these individuals are affected with a psychiatric condition when alcohol and drug abuse are also taken into account. Substance abuse, interfering with the individual's school or work, affects nearly one-third of these individuals.

Scientists believe the high violence rate and recent tragedies such as fatal shootings can be contributed to the prevalence of mental illness in this region.

Findings showed that drinking problems are more prevalent among college students, whereas drug addiction and bipolar disorders were more commonly reported in non-students.
