研究概览
简要总结
The main objective of this study is to characterize a range of brain activation symptoms associated with major depression in peri- and post-menopausal women. Also, assessing brain activation before and after the treatment might help to uncover some mechanisms associated with the pathophysiology of depression and menopause.
详细描述
Women approaching menopause and during the post-menopausal years appear to be at greater risk for developing major depressive episodes. Moreover, this period in life has been associated with significant functional impairment due to the presence/severity of vasomotor symptoms (hot flashes, night sweats), cognitive complaints, and poorer quality of life. In light of recent controversies involving the use of hormone therapies, most physicians and patients are seeking nonhormonal strategies to alleviate menopause-related physical and emotional complaints. Duloxetine has been shown to improve major depressive disorder (MDD) and menopause-related symptoms. To date, the effects of this agent on brain structure and functioning in midlife women with MDD have not been explored. The present study aims to investigate the effects of duloxetine on brain structure and functioning when used for the treatment of a major depressive episode in menopausal women using anatomical magnetic resonance imaging (MRI) and functional MRI (fMRI). In addition, the investigators will examine whether the impact of treatment with duloxetine on vasomotor symptoms, cognition, and quality of life modulate the putative changes in brain structure and functioning.
