The latest edition of DSM, the influential American dictionary of psychiatry, says that shyness in children, depression after bereavement, even internet addiction can be classified as mental disorders. It has provoked a professional backlash, with some questioning the alleged role of vested interests in diagnosis.
It has the distinctly uncatchy, abbreviated title DSM-5, and is known to no one outside the world of mental health.
But, even before its publication a week on Wednesday, the fifth edition of the Diagnostic and Statistical Manual, psychiatry's dictionary of disorders, has triggered a bitter row that stretches across the Atlantic and has fuelled a profound debate about how modern society should treat mental disturbance.
Critics claim that the American Psychiatric Association's increasingly voluminous manual will see millions of people unnecessarily categorised as having psychiatric disorders. For example, shyness in children, temper tantrums and depression following the death of a loved one could become medical problems, treatable with drugs. So could internet addiction.
Inevitably such claims have given ammunition to psychiatry's critics, who believe that many of the conditions are simply inventions dreamed up for the benefit of pharmaceutical giants.
A disturbing picture emerges of mutual vested interests, of a psychiatric industry in cahoots with big pharma. As the writer, Jon Ronson, only half-joked in a recent TED talk: "Is it possible that the psychiatric profession has a strong desire to label things that are essential human behaviour as a disorder?"
