evidence: One of its chief claims is that ADHD prevalence in France is 0.5%, lower than that of the US. This appears to have originated from a 2012 article published in Psychology Today by Dr. Marilyn Wedge (archived here), however, Wedge did not cite any data or peer-reviewed study to support her claim. In fact, a 2011 study conducted by researchers in France disproved this claim, reporting a prevalence between 3.5 – 5.6%[1]. The authors of the study concluded that "the epidemiology of ADHD in French children is similar to the epidemiology of ADHD in other countries". This 2018 article also explains that this claim and others made in the Psychology Today article are false. [...] REFERENCES - 1 – Lecendreux et al.
