Early menopause under the age of 40 could raise the risk for women to be diagnosed with Alzheimer's, according to several recent studies. The disease disproportionately affects women over men.

Ottawa

Recent research indicates that women who experience early or premature menopause face a higher risk of cognitive decline and Alzheimer's disease. Scientists previously attributed the higher prevalence of Alzheimer's in women to longer life expectancy, but new evidence points to hormonal changes as a significant factor.

The study suggests that menopause before age 44, and especially before age 40, is linked to increased dementia risk. Researchers are now investigating whether menopause could be a window for early detection and intervention. The findings have prompted some women to reconsider medical decisions that could induce early menopause, such as elective hysterectomies.

Early menopause linked to Alzheimer's risk, say scientists

She just kept on going. She never rested. She never really took much downtime. Working three jobs, Sonia Cox refused to slow down most her life. But when Alzheimer's symptoms showed up, she deteriorated fast, says her daughter. She forgot my dad first. More women get diagnosed with Alzheimer's than men. For years, scientists assumed that was because women tend to live longer. Now, that understanding is changing. Researchers now think while age does play a role, so too do other risk factors. We are really starting to discover that men and women are different in regard to the risk of dementia. For example, the timing of key hormonal changes like menopause. If the menopause is below age 40, we call it premature. And if it is between age 40 and 44, we call it early. And those are now being shown to be clear risk factors for cognitive decline in dementia. But there's also so much scientists still don't know. We're playing catch-up at this time. Your task is to say what you remember seeing the face. This researcher, searching for early signs of the disease through brain scans and blood samples. We're trying to understand whether or not menopause is a window at which some females might be showing early signs of Alzheimer's disease and whether we could capture them early so they could enter treatment and decide to alter their lifestyles to better age. She actually had a full hysterectomy. Looking back, Angelita now knows her mom was at greater risk for Alzheimer's because her ovaries were removed. That induces menopause and increased her risk of cognitive decline. It's led Angelita to change her choices. I take better care of myself. I'm more aware of the hormonal challenges that I have. So when it became time for me to deal with my fibroids that I had, I chose not to have a full hysterectomy. I know you're going to make your punch. Angelita works two jobs still. But she's trying to slow down and pass those habits down to her daughter. Shada Faryoon, CBC News, Toronto.
