Each month, we curate key research to support evidence-informed ADHD assessment and care.

Chaque mois, nous retenons les études importantes pour appuyer l'évaluation et les soins du TDAH basés sur les données.

Volotinen, Lotta et al. Age at First Attention-Deficit/Hyperactivity Disorder Diagnosis and Educational Outcomes. JAMA Psychiatry, vol. 83, no. 6, Jun. 2026: 620-629.

Comment by Doron Almagor, MD, FRCPC: A new JAMA Psychiatry study from Finland adds to the growing body of evidence supporting timely diagnosis. Following 580,132 young people, Volotinen et al. found that an earlier age at first ADHD diagnosis was associated with a higher GPA at 16, more academic education, and lower school dropout by age 20. Those diagnosed in the last years of compulsory education fared worst, and girls were diagnosed later than boys. CADDRA welcomes your thoughts in the forum.

Commentaire de Doron Almagor, M.D., FRCPC : Une nouvelle étude finlandaise parue dans JAMA Psychiatry s'ajoute au corpus croissant de données appuyant un diagnostic opportun. Volotinen et ses collègues ont suivi 580 132 jeunes et ont déterminé qu'un jeune âge au premier diagnostic de TDAH était associé à une moyenne générale supérieure à 16 ans, à une scolarité accrue et à un décrochage scolaire inférieur à 20 ans. Ceux ayant reçu un diagnostic lors de leurs dernières années de scolarité obligatoire étaient les pires, et les filles recevaient leur diagnostic plus tard que les garçons.
