ADHD and autism at risk of over-diagnosis, says government review

There is a risk of people being over-diagnosed with ADHD and autism, an official review in England has found.

Experts said a rise in diagnoses over the past 25 years meant cases now appear to be outstripping the expected number in the population for some younger age groups.

The review called for tougher regulation of private firms offering assessments for the NHS, saying they had concerns about quality and consistency, and a ban on advertising.
