Newswise — Young boys continue to have the highest rate of autism diagnoses, but Danish doctors are diagnosing more girls, teenagers and adults with the disorder than they did in the mid-1990s. That’s the finding from a 16-year study published 20 February in the Journal of Autism and Developmental Disorders.
Many studies look at the prevalence of autism, akin to taking a snapshot of the number of diagnoses in a given population. The new study instead examined the disorder’s incidence, or newly reported diagnoses, each year.
Between 1995 and 2010, nearly 15,000 people received a new diagnosis of autism in Denmark, the study found. During that time, the incidence of autism overall increased from 9 diagnoses per 100,000 people to 38.6.
