Experts debate on the true incidence and overdiagnosis of PTSD May 6 2021 Some clinicians are concerned that post-traumatic stress disorder (PTSD) diagnosis has risen throughout Western society since the late 1980s. Is this correct? And if so, has the true incidence of PTSD really spiraled out of control, or has it simply become overdiagnosed? Experts debate the issue in The BMJ this week. PTSD is a serious and uncommon condition resulting from severe trauma, but it has unhelpfully become an umbrella term incorporating other disorders and normal reactions to stress, argue John Tully at the University of Nottingham and Dinesh Bhugra at King’s College London’s Institute for Psychiatry, Psychology & Neuroscience (IoPPN).
