Background/Objectives: Perimenopause, impacting 80-90% of women, encompasses a range of vasomotor, urogenital, cognitive, and psychiatric symptoms associated with the fluctuation and gradual reduction of gonadal hormones. Moreover, the onset or worsening of sleep disturbances is prevalent during the menopausal transition. This narrative review seeks to elucidate the pathogenetic processes behind sleep disturbances during perimenopause and the main therapeutic options. Methods: The electronic databases PubMed, Scopus, Google Scholar, Web of Science, and Embase were queried for publications up to May 2024. Longitudinal, observational, case-control, and cross-sectional studies, as well as reviews and meta-analyses, were included in the review in order to explore the prevalence of sleep disorders during perimenopause, the pathogenetic mechanisms underlying the association between menopausal transition and sleep disorders, and the available non-pharmacological and pharmacological treatment options. Results: Sleep disturbances are common among perimenopausal women and include insomnia, sleep-related breathing disorders, and movement disorders. Fluctuations in estrogen and progesterone affect sleep quality, while vasomotor symptoms can disrupt sleep. Circadian changes, decreased melatonin production, and physiological changes associated with aging and mood disorders further exacerbate sleep disturbances. Conclusions: Managing sleep disorders in perimenopause requires an individualized approach, considering the multifactorial nature of these disturbances and providing background knowledge about the relationship between reproductive hormonal changes and sleep. Non-pharmacological treatments should be considered the first-line therapy; hormone therapy or non-hormonal pharmacological treatments can be considered according to the patients' specific needs and risk factors. However, there is still a lack of standards on the appropriate management and treatment of sleep disorders in perimenopause.
