NHS consultant neurologist Dr Suzanne O’Sullivan argues that a range of medical conditions from autism to ADHD are now overdiagnosed, which is completely redefining how we think about sickness and disease. In a new book The Age of Diagnosis; Sickness, Health and Why Medicine Has Gone Too Far, she explains why she believes that creating large numbers of new diagnoses, carries risks for both our mental and physical wellbeing and can turn healthy people into patients. Suzanne is convinced that we should be cautious about having unnecessary medical tests and investigations that may cause more harm than good. And she reveals, perhaps surprisingly, that apart from a small benefit for large bowel cancer, cancer screening has not been shown to have an impact on all cause mortality. Suggesting that although we may be finding cancer earlier, we are not necessarily saving lives. The Age of Diagnosis; Sickness, Health and Why Medicine Has Gone Too Far by Suzanne O'Sullivan is published by Hodder.
