Researchers at UCLA have recently discovered something that I could have told you a long time ago: cognitive decline in women happens sooner than previously thought.
Take for instance a story I was telling a rapt audience (well, maybe not so rapt) just last night. As I struggled to recall the name of a “dear” friend, my audience showed evidence of an internal struggle (walk away while she sorts it out, or stay until the story’s completion?).
In a study that followed over 2,000 middle-aged women over the course of 10 years, researchers from UCLA determined that cognitive decline (previously thought to occur no earlier than around age 60) is occurring in women as early as in their 50s.
The study used two different tests to measure this cognitive decline. The first test involved matching numbers and symbols within a certain amount of time (a measure of processing speed). The second test involved listening to and then recalling a story both immediately after the telling of the story and then 10 minutes after the initial telling (a measure of verbal memory). The participants were tested every year or two within that 10-year period.
The study found an overall 5 percent decline in middle-aged female cognitive function with processing speeds declining by 1 percent every two years and with verbal memory declining by 1 percent every five years.
Historically, such declines have been tied to natural aging. And cognitive decline is a natural part of the aging process. However, there is no obvious cause for the earlier decline. Some researchers speculate that hormone levels might be to blame.
So while it may be too late for me as I struggle to recall my dear friend “whatsherface’s” name, researchers offered the following list of usual suspects to prevent cognitive decline: meditation, exercise, yoga, healthy diet, and a positive outlook on life.
Do you struggle with memory loss? Do you feel that cognitive decline in women happens earlier than for men?
