Remission & chronicity

Spontaneous remission

Spontaneous remission by adulthood: 30-70% symptom reduction (depending on definition); functionally impairing ADHD persists into adulthood in 50-65% of childhood cases; DSMIV criteria met in adulthood in ~50%

Best-intervention remission

Stimulant medications (methylphenidate, amphetamines): 60-80% response rate; MTA study: combined medication + behavioural treatment superior to either alone; behavioural interventions alone: 30-50% symptom reduction in children; non-stimulant (atomoxetine, viloxazine): 40-60% response

Drug-free remission

Relapse after remission

Chronicity

Gap size

Moderate — substantial underdiagnosis especially in girls/women and adults; treatment gaps exist but pharmacotherapy is highly effective when accessed

Primary barrier

access/framing

Barrier detail: Stimulant shortages (2022-present in US) have left many patients without medication; adult ADHD massively underdiagnosed for decades; medication diversion concerns create barriers to legitimate access; non-pharmacological approaches (CBT, exercise, dietary interventions) chronically under-supported

Last SoC change: 2023 — viloxazine (Qelbree) extended-release approved for adults; 2021 serdexmethylphenidate (Azstarys) approved; 2019 lisdexamfetamine approved for adults and children; methylphenidate/amphetamine backbone essentially unchanged since 1955-1960
