From changes in identification to overdiagnosis, experts weigh potential factors in perceived rise in neurodiversity
Some NHS centres twice as likely to diagnose adults as autistic, study finds
Autism is a condition in a state of slow flux. In 2021, a study found a 787% rise in the number of diagnoses between 1998 and 2018 in the UK.
Increases in diagnoses have been a feature of autism for almost as long as it has been a recognised condition: 80 years ago, autism was thought to affect one in 2,500 children. That has gradually increased and now one in 36 children are believed to have autism spectrum disorder (ASD).
