Prof Gina Rippon dismisses too easily the genuine concerns about overdiagnosis of conditions such as autism and the medicalisation of normal behaviour (Why the antagonism over the rise in autism diagnoses? It’s actually good news, 21 July). She correctly observes that there has been an astonishingly large increase in diagnosis rates since 1998. She also notes correctly that, before the 1980s, autism was diagnosed infrequently because of its “overly narrow” definition.
However, in arguing that many children consequently missed out on the help they needed, she draws the wrong conclusion. She fails to mention that other diagnoses were available for such children, including social anxiety, attention deficit hyperactivity disorder and learning disability, among others. Children needing help were frequently diagnosed with one of these, and with sufficient reliability to enable help to be offered within available resources. Moreover, it is well known that the diagnosis of autism by itself does not indicate any specific kind of intervention.
