On 24 April, CIRANO published “Surdiagnostic du TDAH au Québec : Impact de l’âge d’entrée à l’école, différences régionales et coûts sociaux et économiques”, a study by Catherine Haeck and Philip Merrigan, professors at ESG-UQAM and CIRANO Fellows, and two colleagues from UQAM.
In this video, Catherine Haeck and Philip Merrigan, discuss the results of the study and explain their approach and their contribution to advancing knowledge on the issues of overdiagnosis of ADHD in Quebec.
Based on unpublished data from the RAMQ, including the medical service records of nearly 800,000 young people born between 1996 and 2005, the authors draw unequivocal conclusions about the extent of the phenomenon and sound the alarm on this issue of great concern.
