Uncommon Psychiatric Syndromes presents an up-to-date, definitive account of eleven unusual but important clinical disorders. For each syndrome the historical background and present day understanding are given and the worldwide literature is reviewed. Each account gives the principal features of the condition, its causation and underlying psychopathology, illustrative cases and notes on diagnosis and treatment. The fourth edition has been fully updated to include the latest information on causation and treatment and especially the significance of neurodiagnostic findings. The book will be both a practical reference and a fascinating read for all those involved in psychiatry, neurosciences and mental health.
