Major and exciting advances in psychiatric genetics were discussed at a 3-day international workshop. The internationally renowned editors assembledan impressive list of specialists, all of whom are leading in their subject. Reviews and short articles which stress special problems or new research results have been brought together in this book, also including intensive discussions of the different topics. Much of the material covers the application of molecular genetics in major psychoses, Alzheimer's dementia or preclinical research. However, the problems of diagnostic features or phenotypical characterization broaden further the content of this volume, making it truly a collection of the art information.
