Despite this, men’s brains shrink faster than women’s Alzheimer’s New research shows that the disease is being diagnosed more frequently in women.

According to the Alzheimer’s Association, more than seven million Americans have Alzheimer’s and that number is expected to grow to nearly 13 million by 2050. The association says the lifetime risk of Alzheimer’s by age 45 is one in five in women and one in 10 in men.

A Study recently published Proceedings of the National Academy of Sciences To determine whether gender differences in healthy brain aging explain why women are more often diagnosed with Alzheimer’s.

Researchers studied more than 12,000 brain MRIs of nearly 5,000 participants ages 17 to 95 and found that men’s brains shrank faster in more areas than women’s brains. In particular, areas related to memory, emotion and sensory processing were affected, according to the study.

The study found that women had slightly more enlarged brain ventricles, which are fluid-filled spaces inside the brain.

“Our findings show that men experience greater structural brain decline in more areas, meaning that normal brain aging does not explain the gender difference in Alzheimer’s rates,” said the study’s lead author, Anne Ravndal of the University of Oslo. norwaytold fox news digital,

Ravandal said the study results “instead point to other possible explanations, such as differences in longevity, clinical patterns, or biological factors.”

One theory that has emerged regarding the prevalence of Alzheimer’s in women is based on the fact that aging is the primary risk factor for the disease and women live longer than men.

“It’s not clear why this imbalance exists. Longevity has been one explanation, because age is such a strong risk factor for dementia,” said Paola Gilsanz of Kaiser Permanente Northern. California The Research Division said in 2020 Article From the Alzheimer’s Association.

“But now we see that it doesn’t explain everything. So we’re looking at a variety of factors, including biological and social or cultural factors.”
