Peri-menopausal Depression

There is a syndrome of Reproductive Depression related to sudden changes of gonadal hormones. Postnatal depression is perhaps the most obvious and dramatic example of this but it also occurs with cyclical premenstrual depression and peri-menopausal depression. These often occur in the same vulnerable patient who responds abnormally to normal fluctuations of oestrogen and perhaps also progesterone (1).

Although there are randomised studies to show that each component of this triad of hormone responsive mood disorders respond to transdermal oestrogens usually in a dose of 100-200 micrograms of oestradiol patch, such therapy is virtually never used by psychiatrists. We are all products of our training and no doubt psychiatrists are not familiar with the simple problems of hormone therapy such as breast discomfort and uterine bleeding, which could be dealt with by any competent general practitioner (2). In the case of postnatal depression it is much easier for them to use a whole gamut of treatments ranging from mother and child units, SSRI antidepressants and even ECT rather than prescribe oestrogens which are the logical and proven treatment producing a rapid improvement in symptoms (3). It is a predictable that the recent paper from Chile does not mention oestrogens in the wide range of treatments reported (4).

There is experimental evidence that women with a past history of postnatal depression develop more depression on hormonal manipulation that mimics the increase of oestrogen and progesterone with pregnancy and the fall, which occurs post-partum (5).

The tragedy is that the efficacy of oestrogens in the treatment of postnatal depression is as proven as it is logical but still the world of psychiatrists would not consider using oestrogens for this severe disorder nor for premenstrual depression nor for the perinatal depression in the woman who is still having regular or irregular periods. It is not even the WHI data which deters them as this neglect antedated these data. But we should take the reassurance that even the much criticised WHI study showed that women who start oestrogen therapy below the age of 60 have fewer heart attacks, less breast cancer and fewer deaths than in the placebo group (6). Also oestrogens given in the transdermal rather than oral route do not elicit abnormal coagulation patterns.

There is no reason why oestrogens should not be used for postnatal depression but for reasons of ignorance and prejudice.
