A defense neurology expert testified Thursday in the third Risperdal gynecomastia trial about the benefits and risks associated with prescribing the drug to children suffering from Tourette syndrome.

Dr. Lawrence Brown, who practices pediatric neurology at the Children’s Hospital of Pennsylvania, told jurors about the circumstances under which he prescribes Risperdal and other antipsychotics, as well as the wisdom of plaintiff Tim Stange’s doctor’s prescription of the drug.
