Menopause brings a decline in estrogen levels, which can impact brain function and mood. Women may experience symptoms such as hot flashes, memory lapses, and mood swings. Estrogen is thought to have a protective effect on the brain, and its reduction during menopause may increase the risk of cognitive decline and neurodegenerative diseases. Hormone replacement therapy (HRT) can help alleviate some of these symptoms, although it must be approached carefully due to potential risks.
