Leading and internationally recognized researchers review what is known about the liability to schizophrenia, how it progresses, what it looks like clinically-with an emphasis on a specific (proposed) syndrome of liability (schizotaxia)-and how best it might be treated now and in the near future. The authors summarize the latest findings on the genetic, early environmental, and neurodevelopmental origins of schizophrenia.Leading and internationally recognized researchers review what is known about the liability to schizophrenia, how it progresses, what it looks like clinically-with an emphasis on a specific (proposed) syndrome of liability (schizotaxia)-and how best it might be treated now and in the near future.
