At age 5 my son was diagnosed ADHD he has been treated with medications for 6 years now. He is currently taking Aderall XR 30mg/Trileptal 300mg/seroquel 500mg/Trazadone 100mg a day.The medications were doing fine but for the past month have had little or no effect on him. His Dr now says that he may have severe Bipolar Disorder. She suggested that we may have to use Lithium. He is now 10 and I heard that it is not good to use on a child under 12. Does anyone have a child under 12 who is currently on Lithium? If so how is it working? I have heard a lot of pros and cons but I dont want to harm my son but if he is not treated Im afraid he may hurt himself or others.
