A new study in the United States says mental disorders appear to be common in college-age adults, but most do not seek treatment. (26)The study compared the mental health of college students to that of non-students of the same age.
    The researchers found that twenty percent of college students abused alcohol--the most common disorder in that group. Personality disorders came next. The study says almost eighteen percent of college students appeared to have a personality disorder. That was true of about twenty-two percent of those not in college.
    (27) The college students were also less likely to have a drug-use disorder, nicotine dependence. And they were less likely to have used tobacco. But their risk of alcohol disorders was greater.
    Over all, the study found that almost half of all the college-age individuals showed signs of at least one psychiatric disorder. The researchers say this age group may be especially sensitive to disorders (28) because of the great pressures of entering adulthood. Yet they say only one-fourth sought treatment.
    Joseph Glenmullen is a psychiatrist at Harvard Medical School who (29) believes that psychiatric medications are overused. He told the news agency that the finding of a psychiatric disorder in about half of those studied "seems extraordinarily high." He says that they find more people with milder symptoms. What he is saying is that more people may be told they have a mental disorder because the definitions have been widened.
