This text provides comprehensive coverage of psychiatry. Written primarily for students, it covers both behavioural science and clinical psychiatry. It also considers: biological therapy, including all current drugs, with classification by action and drug name; neurochemistry; neurophysiology; and brain imaging. Clinical cases are included and pharmacologic treatments are presented according to pharmacologic activity, not just by drug family. This seventh edition has been updated to incorporate the DSM-IV guidelines. It also includes expanded coverage of substance abuse and psychotropics. New topics to this edition include factitious disorders; eating and sleep disorders; medication-induced movement disorders; motor skills and attention deficit disorders; schizophrenia with childhood onset; and childhood or adolescent antisocial behaviour.
