Professor Ian Hickie is a psychiatrist and co-director of health and policy at the University of Sydney's Brain and Mind Centre. As one of Australia's leading authorities on mental health, Professor Hickie says that disinformation can risk putting people with clinical depression off using potentially successful treatments. One of the most damaging myths: that antidepressants don't work. In his latest book The Devil You Knew, Hickie tackles these harmful myths and explores the spectre of depression and the myriad influences - such as environmental, physiological, social - to guide readers towards the correct diagnosis and offer pathways to healing.
