Throughout the book, the authors present implications for future research, some of which would significantly alter the way we have studied schizophrenia. For example, because of the difficulty in ascertaining exactly what risks are transmitted by genes, the authors suggest that future molecular genetic research should encompass a much broader phenotype. In fact, one chapter calls into question the traditional view of schizophrenia as a discrete entity rather than an extreme end of a continuum. Several chapters emphasize the need for interdisciplinary collaboration, including neuroimaging, molecular genetics, and nosology.
