Poor Mental Functioning Could Predict Stroke

Researchers found that older men who were not diagnosed as having dementia but who did poorly on a test of mental function had a greatly increased risk for stroke. 


According to the American Association for Critical Illness Insurance about 600,000 Americans experience their first stroke each each.  “Some one in the U.S. has a stroke every 40 seconds,” explains Jesse Slome, the non-profit educational organization’s director.


 Medical researchers at Uppsala University published theuir findings yesterday Neurology.  There are indications that the test results could show the chances of survival for someone who has a stroke, they noted.


The research involved nearly 1,000  Swedish men, who averaged 70 years old at the start of the study. None had a history of stroke. They were given three widely used tests of mental function.  Over the next 13 years, 166 of the men had a stroke or transient ischemic attack (TIA), a brief interruption of blood flow to the brain.


The 25 percent of men who performed worst on the B test were three times more likely to have a stroke or a TIA than the 25 percent of the men with the highest scores, the study found.  The results support the idea that cognitive decline, regardless of whether a person has dementia, may predict risk of stroke, researchers explained. 

The Swedish study adds to the list of unconventional factors linked to the risk for stroke.  One recent study of more than 13,000 Americans found an association with obesity, measured by either body-mass index or waist circumference. In some cases, the most obese individuals were more than three times as likely to have a stroke as the leanest.
