00:00Stroke happens every 40 seconds in the U.S., and lower memory scores may flag hidden risk.
00:05A September study in the Journal of the American Heart Association tracked 4912 adults for 12.3 years.
00:13Among 3094 people aged 60 to 69, lower test scores meant more strokes later on.
00:19Researchers reported up to an 86% higher risk with lower overall thinking ability.
00:24They also found a 68% higher risk with weaker episodic memory, and slower information processing came with a 66
00:32% higher risk.
00:33But they found no clear link in people 70 and older after adjustments.
00:37The researchers say silent strokes may explain part of that pattern.
00:41Christopher Yee, M.D., at Memorial Care Orange Coast Medical Center, called that very plausible.
00:48Still, he noted the study did not use MRI to confirm it.
00:51Dirk W. Krieger, M.D., Ph.D., at Rye Cognition Health, said the link remains unproven.
00:59So experts say cognitive testing is not yet a routine stroke risk check.
01:03For now, the question is whether lower scores are a warning sign.
