A Controlled Trial of Serotonin Reuptake Inhibitors Added to Stimulant Medication in Youth With Severe Mood Dysregulation

Summary

Severe mood dysregulation (SMD) is a very common syndrome in children. Its symptoms include very severe irritability, including persistent anger and frequent outbursts, as well as distractibility, hyperactivity, and other symptoms of attention deficit hyperactivity disorder (ADHD). Many children with SMD receive the diagnosis of bipolar disorder (BD) in the community, although they do not have clear manic episodes (with symptoms such as extreme happiness and decreased need for sleep). Because SMD has not been studied in depth, we do not know which medications are most helpful to those with SMD. This study will evaluate the effectiveness of the stimulant medication methylphenidate (MPH, more commonly known as Ritalin ) when combined (or not combined) with the antidepressant citalopram (Celexa ) in treating symptoms of SMD in children and adolescents. This study will provide information about how to treat SMD in youth. This study will include approximately 80 patients between 7 and 17 years of age with SMD. The patient s symptoms must have started before age 12. The study will consist of four phases carried out over 4 to 5 months. During Phase 1, the patient will undergo blood and urine tests, and will gradually taper off his or her medication. The duration of this phase depends on the patient s medication before starting the study. In Phase 2, the patient remains off all medication for 1 week. In Phase 3, the patient will be treated with MPH for 2 weeks, and then will be randomly assigned to receive either MPH plus citalopram or MPH plus a placebo for a further 8 weeks. In Phase 4, the researchers will evaluate the effectiveness of the medications taken, and begin an open treatment phase using medications that they deem appropriate for that patient (this may include MPH with citalopram and/or other medication combinations). Most patients will be admitted to the Pediatric Behavioral Health Unit at the National Institutes of Health Clinical Center during the medication withdrawal part of the study (Phases 1 and 2). From Phase 3 on, a patient may participate as an inpatient, outpatient, or in day treatment, depending on what is in his or her best interests. ...
