Menstruation in Relation to Mental Disorders

In July, 1927, at a British Medical Association meeting, in the Obstetrics and Gynæcology Section, G. I. Strachan dealt with the mental side of the hygiene of menstruation. He made the statements that in cases where menstruation was influenced in mental disease it was usually in the direction of excess, and moreover he had found no justification for the text-book statement that insanity was usually accompanied by amenorrhœa. A study of the more important text-books of psychiatry reveals a paucity of information on the subject, and this has stimulated me to collect any facts which have bearing on this interesting problem.
