Research into the neuropsychiatry of epilepsy has become a central focus of interest in the last five years. Comorbidity of epilepsy with behavioral problems is now recognized widely, and the neuroscientific basis for such comorbidity is an active area of investigation. With an expanded international team of authors, this fully revised new edition builds on the strengths of its predecessor, examining in detail the subtleties of behavioral changes in patients with seizure disorders and offering both a diagnostic and a management perspective. New chapters cover genetic disorders, the effects of epilepsy on social behavior as viewed through theory of mind, a discussion of the precuneus, the importance and nature of peri-ictal psychiatric symptoms, depression and the interictal dysphoric disorder, and the relationship between antiepileptic drugs and suicide. This new edition is a must for anyone involved in diagnosing or managing epilepsy.
