My 11 yr old granddaughter appears to have ADHD and is what school and counselors are calling it, but I am concerned it may be misdiagnosed. She has problems concentrating, is immature for her age, has behavior problems, cannot be still or follow more than a couple of directives at a time. She has severe kidney problems, constipation, sleep problems and lately is being bullied at school. She is very impulsive. They have her on meds for adhd, sleep medications and meds for her kidney and constipation. Could she have been misdiagnosed? Should she see a specialist of some type who looks at the overall problems, instead of several doctors for each problem?
