My daughter was diagnosed with ADHD at 8 years old and was on aderall which we had to change due to appitite drop and depression. she has been on concerta until this week. Our PCP just changed her concerta to vyvance. she was having headaches and moody so her Dr. prescribed Lamotragine, but she was never diagnosed with bipolar disorder just ADHD and Impulse disorder. is this a new name for bipolar? Should I be concerned?
