The perimenopause is an individual experience, influenced by life circumstances, cultural context, family history and narrative. The perimenopause can last many years and women, as well as health professionals, can be poorly prepared for this potentially challenging period. Most people know to expect hot flushes, and maybe genitourinary symptoms. However, if the emotional symptoms, such as, reduced ability to cope, irritability and sudden anger, arise first, years before the expected hot flushes, it can be difficult to understand and have a detrimental effect on a woman’s life. We explore widespread physical symptoms of perimenopause and highlight symptoms that are regulated in the brain: hot flushes, body temperature regulation, sleep disturbances, libido. We focus on emotional symptoms, such as mood changes, depression, anxiety, agitation, irritability, a sense of overwhelm and losing the ability to cope, and explore their impact on suicidality. We briefly look at cognitive symptoms and explore the influence of trauma and the differences in experience by ethnicity and cultural influence. Finally, we look at the experience of premature ovarian insufficiency.
