Note that this cross-sectional study of adolescents demonstrated an association between various psychiatric disorders and lower fluid intelligence (IQ) scores.
In contrast to prior studies, post-traumatic stress disorder diagnoses were not associated with lower IQ.
Teenagers with various psychiatric disorders were linked with having lower average levels of "fluid intelligence," or IQ, compared with teens without these disorders, data from a large national survey found.
The study, by Katherine M. Keyes, PhD, co-director of the Psychiatric Epidemiology Training Program at Columbia University Mailman School of Public Health, and colleagues, found that after adjustment for confounders, adolescents ages 13 to 18 with bipolar disorder, various disruptive behavior disorders, substance use disorders, and specific phobias were associated with significantly lower mean IQ levels than their counterparts without these disorders.
