Hormone therapy reduces Alzheimer’s risk

A new study, published in an online issue of the medical journal of theAmericanAcademyof Neurology, has shown that women who begin taking hormone replacement therapy within five years of menopause may reduce their risk of developing Alzheimer’s disease.

The study is in a contentious area of medicine, as multiple studies have shown hormone replacement therapy both increasing and decreasing the risk of Alzheimer’s. The new study focuses on the timing of hormone replacement therapy.

It followed 1768 women aged 65 and over for 11 years. It found that women who began hormone replacement therapy within five years of menopause had a 30 per cent lower risk of Alzheimer’s. The risk was unchanged for those who started more than five years after menopause, but a higher risk of dementia was observed in women who started a combined therapy of oestrogen and progestin after they turned 65.

More research is needed before a conclusive result can be reached, however, it does suggest that the timing of hormone replacement therapy is important.
