The theme of the seasonal tendency of schizophrenic births certainly is not new for experimental psychiatry. The tendency was first noted about 60 years ago by Tramer (1), who noted an excess of schizophrenic births during the winter and early spring. Following this, a large number of studies were undertaken, taking thousands of cases into consideration (for references, see 2,3,4). Undoubtedly, some uncertainty still exists about the role each month plays in generating this asymmetrical distribution of schizophrenic births as well as about the exact dimensions of this phenomenon. Nonetheless, the association between the future condition of schizophrenia and birth in the period of the year between December and April (in the northern hemisphere) is no longer the subject of doubt.
