Streeting orders probe of mental illness overdiagnosis

The health and social care secretary is to launch a review of the prevalence of mental illness and neurodivergence, with a particular focus on whether some conditions are being overdiagnosed, HSJ has revealed.

HSJ understands the review has been commissioned by Wes Streeting, and will be chaired by leading psychoanalyst and clinical psychologist Peter Fonagy. Former Royal College of Psychiatry president and NHS England board adviser Sir Simon Wessely will be vice chair.

The review is expected to be announced in coming weeks, sources say.

It will be launched in the content of rising concern about the number of people receiving benefits because they are deemed unfit for work due to mental health problems. There is also alarm over the very long waits and backlogs for diagnosis and treatment for some conditions, particularly ADHD and autism, and for mental healthcare. There has been a big increase in recognition and diagnosis of ADHD in particular in recent years, in both children and adults.

Prime minister Sir Kier Starmer told the BBC this morning that some money allocated to health benefits for those suffering from mental health problems might better be spent on their treatment.

Asked if ”being anxious, even being depressed… a good enough reason for stopping looking for work?, the PM replied: ”We need to look again at this issue of mental health, and ask ourselves a fundamental question, which is ‘would we not be better putting our money into the resources and support that is needed for mental health’, than simply to say it is to be provided in benefits.”
