Perimenopause Depression
Perimenopause is the 4–10 years before the final menstrual period — a transition most women enter in their early-to-mid 40s, with some noticing hormonal shifts as early as the late 30s. During this window, estrogen, progesterone, and testosterone don’t simply decline. They fluctuate — sometimes wildly — before settling at lower postmenopausal levels.
