Koenen KC, Moffitt TE, Roberts AL, et al. Childhood IQ and Adult Mental Disorders: A Test of the Cognitive Reserve Hypothesis. Am J Psychiatry. 2009 Jan;166(1):50-7. Epub 2008 Dec 1. (Original)
OBJECTIVE
Cognitive reserve has been proposed as important in the etiology of neuropsychiatric disorders.
However, tests of the association between premorbid IQ and adult mental disorders other than schizophrenia have been limited and inconclusive.
The authors tested the hypothesis that low childhood IQ is associated with increased risk and severity of adult mental disorders.
CONCLUSIONS
Lower cognitive reserve, as reflected by childhood IQ, is an antecedent of several common psychiatric disorders and also predicts persistence and comorbidity.
Thus, many patients who seek mental health treatment may have lower cognitive ability ; this should be considered in prevention and treatment planning.
