For three decades psychiatrists have turned to Lishman's Organic Psychiatry as the standard neuropsychiatry reference. It stood as the last great single author reference text in medicine, a combination of meticulous, exhaustive research conveyed in a beautifully clear style. Now the mantle has been passed to a group of five distinguished authors and it is to their considerable credit that the attributes which made Organic Psychiatry such a distinctive voice remain. The fourth Edition of Lishman's Organic Psychiatry is a rich blend of detailed clinical inquiry and up to date neuroscience. It should be on every psychiatrist;s book shelf. -Anthony Feinstein, MPhil, PhD., FRCP, Professor, Department of Psychiatry, University of Toronto, Canada Over the past 30 years, thousands of physicians have depended on Lishman's Organic Psychiatry.
