NIDA Reports On Comorbidity Of Addiction, Other Mental Illnesses
The National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, today released a research report, Comorbidity: Addiction and Other Mental Illnesses, summarizing the state of the science regarding the complex relationship between substance abuse and other mental disorders. The release of this report is timely given the increasing prevalence and link between post traumatic stress disorder and substance abuse, to be discussed today at a NIDA sponsored meeting, Addressing Substance Abuse and Comorbidities Among Military Personnel, Veterans and Their Families.
For the past 20 years, national surveys have documented the high prevalence of drug abuse among individuals diagnosed with other mental illnesses and vice versa. For example, studies show that people diagnosed with mood or anxiety disorders are about twice as likely to also suffer from a drug use disorder, and the inverse is also true.
"We do not know enough yet to predict precisely whether one disorder will lead to the other(s) or how to prevent comorbidity," said NIDA Director Nora D. Volkow, M.D. "We do know, however, that the high rate of comorbidity means that we need a comprehensive approach to intervention that identifies, evaluates, and treats each disorder concurrently."
NIDA’s research report, Comorbidity: Addiction and Other Mental Illnesses, describes common factors that can lead to comorbidity, including genetic and gender vulnerabilities, involvement of similar brain regions, and the influence of developmental factors; and discusses how comorbidity can be diagnosed and treated. Several examples of behavioral therapies tested in patients with comorbid conditions — as well as potential medications — are outlined in the research report.
