Dr. James M. Noble of Columbia College of Physicians and Surgeons in New York City and his team also found that adults with the highest levels of this pathogen were twice as likely to fail three-digit reverse subtraction tests. The researchers findings are published in this months edition of the Journal of Neurology, Neurosurgery, and Psychiatry. They are based on over 2300 men and women who were tested for periodontitis and completed many thinking skills tests as part of the National Health and Nutrition Examination Survey III conducted between 1991 and 1994. The researchers reported that overall, 5.7 percent of the adults had difficulty finishing certain memory tasks and 6.5 percent failed reverse subtraction tests. The subjects with the highest (greater than 119 units) versus the lowest (57 units or lower) pathogen levels were most likely to do poorly in these tests. Previous research has already made a strong connection between poor oral health and heart disease, stroke and …
