Menopause

Sleep problems (i.e., insomnia) affect midlife women as they approach and pass through menopause at rates higher than at most other stages of life. The purpose of this article is to critically review what is known about insomnia (perceived poor sleep) and physiologically assessed sleep, as well as sleep-related disordered breathing (SDB), in women according to menopausal status and the role of hypothalamic-pituitary-ovarian (HPO) hormones. Self-report evidence that sleep difficulties are related to the hormonal changes of menopause is mixed.

OBJECTIVE: Among women with breast cancer, hot flashes are frequent, severe, and bothersome symptoms that can negatively impact quality of life and compromise compliance with life-saving medications (eg, tamoxifen and aromatase inhibitors). Clinicians' abilities to treat hot flashes are limited due to inadequate understanding of physiological mechanisms involved in hot flashes. Using an acute tryptophan depletion paradigm, we tested whether alterations in central serotonin levels were involved in the induction of hot flashes in women with breast cancer.
