ADHD (over) diagnosis: fiction, fashion, and failure

ADHD (over) diagnosis: fiction, fashion, and failure
ADHD (over) diagnosis: fiction, fashion, and failure
When thoroughly assessed, the prevalence of ADHD in children/adolescents is estimated at 5%. There is no evidence that ADHD is over-diagnosed in the UK. Indeed, available data point to under-diagnosis, even though rigorous updated post-Covid-19 pandemic data are not available. Some cases may be misdiagnosed due to low-quality assessment, poor adherence to national guidance, or inappropriate differential diagnosis. Beyond the controversy around over- or under-diagnosis and over-medicalisation of ordinary behaviours or emotions, the main issue is that UK clinical services cannot adequately support individuals with ADHD who need help. There is a risk that the narrative claiming ‘ADHD is over-diagnosed’ could be used to deny people with properly-diagnosed ADHD the care they deserve.

Abstract

When thoroughly assessed, the prevalence of ADHD in children/adolescents is estimated at 5%. There is no evidence that ADHD is over-diagnosed in the UK. Indeed, available data point to under-diagnosis, even though rigorous updated post-Covid-19 pandemic data are not available. Some cases may be misdiagnosed due to low-quality assessment, poor adherence to national guidance, or inappropriate differential diagnosis. Beyond the controversy around over- or under-diagnosis and over-medicalisation of ordinary behaviours or emotions, the main issue is that UK clinical services cannot adequately support individuals with ADHD who need help. There is a risk that the narrative claiming ‘ADHD is over-diagnosed’ could be used to deny people with properly-diagnosed ADHD the care they deserve.
