Not true that you cannot be ADHD and gifted. My son has both. ADHD is a medical condition, gifted is a measurement of intellect just like an IQ score and they have no effect on each other in terms of co-existing. Many kids who are smart don’t get diagnosed because of this misconception. I would suggest a second opinion as well. For us medication means the difference between good grades and amazing grades, between being in school and “coping” or being in school and thriving. Your child should be allowed to achieve their full potential and another doctor who specializes in ADHD will be able to advise you better than someone who is a generalist. ADHD can look different from one kid to another.
