title: Is the concept of schizophrenia useful from an aetiological point of view? A selective review of findings and paradoxes.
abstract: In this selective review of findings from aetiological schizophrenia research, attention is focused on problems of classification and paradoxical observations in family and twin research, as well as interesting findings from high risk studies. The author raises the question if our modern classification of the functional severe mental disorders hampers aetiological research.
