Dr. Mark Olfson, TeenScreen National Center’s scientific advisor, is professor of clinical psychiatry and a mental health services researcher and research psychiatrist at Columbia University and the New York State Psychiatric Institute.
He is a leading expert on the impact of increased diagnoses and prescribing of antipsychotic medications on our youth – concerns that have generated serious discussion within the mental health and medical communities. Improving diagnosis and treatment of bipolar disorder in young people will be the focus of our February 29 webinar, Bipolar Disorder in Adolescents: What Primary Care Providers Need to Know, which we are co-hosting with the American Academy of Pediatrics.
Here, Dr. Olfson shares his thoughts on the controversy and discusses how new research findings may help settle it.
Over the past several years, an increasing number of children and adolescents in the U.S. have been diagnosed and treated for bipolar disorder1,2. As part of their treatment, a majority receive psychotropic medications, often a mood stabilizer and an antipsychotic medication. A recent meta-analysis suggests that antipsychotic medications may be more effective than mood stabilizers for the treatment of manic symptoms in bipolar youth3. Yet weight gain and other adverse metabolic side effects associated with antipsychotic medications4 pose important considerations. As compared with adults, children and adolescents may be more vulnerable to antipsychotic-induced weight gain5 and perhaps even to antipsychotic-associated diabetes6,7.
When the diagnosis is clear, than the benefits of these medications often far outweigh the risks. However, there is growing concern over the accuracy of some of these diagnoses8, 9. Symptoms of increased irritability – often interpreted as symptoms of bipolar — also occur in ADHD and disruptive behavior disorders, and may contribute to a tendency among some clinicians to overdiagnose bipolar disorder10. Even among child and adolescent psychiatrists, there is variation in the clinical criteria used to make a bipolar diagnosis. Many are either uncertain or reject the concept that a child must have the primary DSM-IV criterion for a manic episode (at least one week of elevated, expansive, or irritable mood) to receive bipolar disorder diagnosis8.
Concern over high rates of community bipolar disorder diagnosis in young patients has led the DSM-5 Task Force to propose a new diagnosis: disruptive mood dysregulation disorder. This disorder includes youth with recurrent temper outbursts that are out of proportion – both in duration and intensity — to the stressor that provoked them and that are not connected to an existing mood or psychotic disorder. Although the effects of this new disorder on medical practice remain unknown, epidemiological data suggest that disruptive mood dysregulation disorder occurs in approximately 3.3% of children and adolescents11.
Despite substantial progress in combining psychosocial therapies for adults with bipolar disorder, much less research has focused on child and adolescent bipolar patients. Recently, however, family-focused therapy, which emphasizes communication and problem-solving skills training to enhance family functioning, in combination with pharmacotherapy, has been found to contribute to more rapid and complete remission of depression symptoms than a combination of brief psychoeducation and pharmacotherapy12. Support also exists for multifamily group psychoeducational therapy for children with bipolar disorder in reducing mood symptoms13.
Uncertainty and controversy often surround the diagnostic boundaries of bipolar disorder for children and adolescents. In this clinical context, it is important that mental health professionals apply the DSM criteria in a standard and consistent manner, approach pharmacotherapy with an understanding of its efficacy and risks, and seek to take advantage of emerging evidence that interventions that work on family communication and functioning may play an important supporting role in improving the course and outcome of children and adolescents with bipolar disorder.
