Scope note. “ADD” is historical terminology commonly mapped to the current predominantly inattentive presentation; this condition covers all presentations and the full lifespan, including adult ADHD (Leffa 2022, PMID 35397064).
The condition in five sentences. ADHD is a clinically diagnosed neurodevelopmental disorder defined by developmentally atypical, persistent and impairing inattention and/or hyperactivity-impulsivity across settings; diagnostic tools may support assessment but do not replace clinical synthesis (Wolraich 2019, PMID 31570648; Peterson 2024, PMID 38523599). Prevalence is method-dependent—1.6% in registers, 5.0% in surveys, 4.2% in one-stage clinical studies and 4.8% in two-stage studies—while adult estimates diverge between persistent (2.58%) and symptom-defined (6.76%) ADHD (Popit 2024, PMID 39381949; Song 2021, PMID 33692893). Liability is highly heritable and polygenic, with the first large GWAS identifying 12 loci but providing no individual diagnostic test (Faraone 2019, PMID 29892054; Demontis 2019, PMID 30478444). Stimulants show the largest short-term average symptom effects, with nonstimulants, behavioral care, CBT, school supports and digital interventions targeting different needs; durable functional evidence remains thinner than acute efficacy evidence (Cortese 2018, PMID 30097390; Liu 2023, PMID 36794797). The major frontier is not proving that ADHD exists, but improving recognition without diagnostic inflation, matching treatment to patient-priority function, and resolving long-term benefit and harm in underrepresented groups (Hinshaw 2022, PMID 34231220; Li 2024, PMID 38470385).

Reading paths¶
- Clinical path — overview → diagnosis → differential diagnosis → guidelines → pharmacologic and psychosocial/digital treatment → safety
- Developmental path — history and presentations → epidemiology/course → childhood/adolescence → adult ADHD → girls/women
- Science path — genetics/neurobiology → cognitive phenotypes → biomarkers → clinical trials
- Human/outcomes path — patient experience → long-term outcomes → statistics
- Unknowns path — OPEN-QUESTIONS.md → the Open questions section of each page → clinical trials

Curation state¶
The condition was built on 2026-08-28 and independently audited on 2026-08-30. All 18 wiki pages are curated: every cited PMID and NCT ID resolved live, reference metadata and substantive claim pairings were checked, numerical transcriptions were reconciled, and dated absence searches were rerun. The audit added one newly retrieved biomarker paper, bringing the bibliography to 455 records, and corrected stale guideline and organization status claims.
