Even worse than asking a silly question is paying lawyers to answer it for you. Treatability was never a yes/no matter and all we have to show for years of medico-legal argument is an expensive ‘maybe’ and the absurd suggestion that sitting in hospital is treatment. Meanwhile other doctors quietly dropped the notion of ‘incurables’ long ago. So let the lawyers and independent experts earn their money elsewhere. Personality disorder is a psychological disability. Quick or simple remedies are no more likely than for chronic schizophrenia – and the principles of rehabilitation are also the same. So get on with it.
