New research supports adding risperidone (brand name Risperdal) and parental training to traditional attention-deficit hyperactivity disorder medications for kids with severe aggression.Studies have shown that the regimen of psychotropic and stimulant medications, in addition to parental training, helps relieve childhood anxiety and reduces disruptive behavior. The new study results confirm previous findings by researchers at Ohio State University Wexner Medical Center and three other institutions. They have showed that when children with attention-deficit/hyperactivity disorder (ADHD) and serious physical aggression were prescribed both a stimulant and an antipsychotic drug- along with teaching parents behavior management techniques- they had a reduction of aggressive and serious disruptive behavior.The new study, by L. Eugene Arnold, M.D., and Michael Aman, Ph.D., has been published online in the Journal of Child and Adolescent Psychopharmacology (JCAP). Risperidone was first approved by the U.S. Food and Drug Administration as an antipsychotic medication for treating schizophrenia more than 20 years ago, and its use has expanded to include symptoms of bipolar disorder and autism spectrum disorders. It has not yet been okayed for treating aggression in ADHD.
