Besides the well-defined nosological groups such as schizophrenia and affective disorders, the so-called schizoaffective disorders remain in an intermediate position. Biological features tend to build up links between these two disorders and support the hypothesis of a biological continuum between schizophrenia and affective disorders. Among these biological factors, neuroendocrinology, brain neurotransmission and sleep seem to be particularly relevant. This "continuum" hypothesis may also be supported by therapeutical and epidemiological data.
