Estrogen And Alzheimers

Estrogen, a hormone primarily involved in female reproductive health, has been linked to Alzheimer's disease (AD) and dementia. Research suggests that estrogen has neuroprotective properties, potentially reducing the risk of AD. It influences brain function by promoting synaptic plasticity, enhancing cerebral blood flow, and reducing inflammation. Postmenopausal women, who experience a significant drop in estrogen levels, show a higher incidence of AD, implying a connection between estrogen deficiency and cognitive decline. Hormone replacement therapy (HRT) has been explored as a preventive measure; however, its efficacy and safety remain controversial, with studies showing mixed results. Understanding estrogen's role in neuroprotection could lead to new therapeutic strategies for combating Alzheimer's and other dementias.
