About

Many perimenopausal women experience severe mood symptoms for the first time in their life, with no past psychiatric history. The importance of clearly identifying and treating a disorder that is increasingly referred to as "perimenopausal depression" is highlighted by the wide-reaching impact this can have on the lives of women suffering from it. This is not a minor or short term mood disturbance; it is a severe depressive illness, needing effective and early treatment. Relationships, employment, participation in social roles and individual well-being can all be disrupted by the combination of the mood, hormonal and physical changes associated with the transition to menopause. The term "perimenopausal depression" denotes the onset of depression coinciding with the onset of reproductive hormone changes.

Many women with this type of depression experience serious and long term debilitating symptoms. Treatment commonly draws on traditional approaches for the management of major depression including the use of antidepressants such as selective serotonin reuptake inhibitors (SSRIs) as the first line response. However, standard treatment of perimenopausal depression using antidepressants has only shown small improvements at best and at worst, is associated with severe side effects. Some SSRIs have been shown to be less effective in postmenopausal women compared to child bearing age women. Hormone treatments directly targeting the fluctuating reproductive hormone systems (in particular estrogen) through the administration of compounds such as tibolone, have significant potential as a better overall treatment.

To date, there is still a lack of clear clinical evidence about the best approach for the biological treatment of women with perimenopausal depression. The project we now propose to conduct is a 12-week randomised controlled trial (RCT) of 2.5 mg/day tibolone compared to 10mg/day of escitalopram (an SSRI that has targeted serotonin action)compared to placebo to discover the best treatment approach for a hitherto understudied depression that affects a large proportion of women in their late forties and fifties.

Full description

All women experience menopause and a significant number suffer from ongoing, severe depression beginning with the major hormone fluctuations in this middle stage of life. The number of women experiencing menopause related major depression and the impact of this depression on the woman's life, work and her family are grossly underestimated. We propose to conduct a clinical trial of a new hormone treatment for women with severe depression related to menopause, compared with standard antidepressant medication.

Longitudinal epidemiological studies have shown that many women experience significant physical and psychological changes as they approach menopause and for a long time following. Vasomotor symptoms (such as hot flushes, night sweats), sleep disturbances and changes in libido are common, and impact significantly on the quality of life, social and personal well-being. However, the major reason that many women seek help from menopause clinics or their doctors, is for depression and anxiety symptoms.
