This is probably too late for your MD appt, but your son sounds so much like mine (except mine is older – 16). Honestly medicine is the main treatment that has helped with focus (though not organization, planning etc). Your son sounds like he has predominantly Inattentive ADHD like mine. We tried the methylphenidate meds like Concerta, Ritalin, and Focalin and they did not help at all. Vyvanse, an amphetamine based med, has worked the best and he’s been taking it since he was 7. Vyvanse targets the neurotransmitters dopamine and norepinephrine. Concerta and the like mainly only affect dopamine. If your MD has not tried it yet, ask to try Vyvanse or a similar medicine like Adderall.
