Ibid., 1, 143. -and McIntosh, C. A. (1934) Many writers have expressed the view that no form of psychiatric illness occurring in pregnancy or the puerperium is a specific clinical entity. The general opinion seems to be that the ordinary stress and strains of pregnancy, operating in predisposed individuals, produce non-specific mental illnesses which are indistinguishable from other mental reactions and are due to the interaction of factors-the pregnancy being of psychological importance only. Brew and Seidenberg (1950) state that these disorders occur only in predisposed individuals, and disregard the possibility that a physiological or endocrine disturbance may be the primary activating factor.As other surveys have been made only on patien.s who have been admitted to mental hospitals these conclusions are not justified; and as no psychiatric survey of women confined in maternity hospitals has been undertaken there is no evidence about the importance of alleged psychogenic factors.The question has been considered afresh by studying the case records of all the women delivered at maternity hospitals in Bristol between January, 1938, and June, 1948, a period of 104 years, the cases numbering about 37,000. Physical and psychological factors were noted in order to ascertain their importance. The incidence, nature, and outcome of mental reactions were studied, and all cases of mental illness related to the puerperium or pregnancy that were treated in Bristol Mental Hospitals during the same period were examined by me, thus there was a double check and control. The tables relate to these surveys. Reference has also been made to some other cases, which were not included in the surveys as they occurred in other years or outside Bristol.
