409. Oral health affects reasoning ability

A study conducted at Columbia University states that good oral hygiene can help adults maintain healthy reasoning. According to an article published in the latest edition of the Journal of Neurology, Neurosurgery, and Psychiatry, people over 60 years with gum disease have more difficulty remembering a sequence of three words after a while. Furthermore, they are twice as likely not to move in tests with calculations subtracting three-digit numbers.
Researchers have resorted to more than 2300 men and women to examine their oral health to see your reasoning. Overall, 5.7 percent of adults had trouble completing some tests of memory and 6.5 percent did not complete the tests of subtraction.
Participants with higher levels of bacteria had the worst results in these tests. Among other risk factors for loss of mental function, researchers highlighted the inflammation caused in whole body because of poor oral health. Other investigations have linked this issue with other diseases such as diabetes and Alzheimer's.
