Alzheimer's, Diabetes Link Studied
Researchers at Kyushu University in Japan have found that people at risk of diabetes also have a tendency to develop pigmented spots on the brain that are characteristic of Alzheimer's disease.
Neuropathologist Toru Iwaki led the team‚ which found that people with persistently high blood glucose tend to develop the lesions‚ usually seen in the elderly. The researchers looked at data provided by a long–term study on residents in Hisayamamachi, Fukuoka Prefecture‚ looking at the relationship between diabetes risk factors and the brain lesions in 135 individuals. The study subjects' average age was 79.5‚ and they were examined in 1988 and died between 1998 and 2003. Investigators found brain lesions in 88 of those examined. Patients who experienced elevated blood glucose levels after meals were 1.7 times more likely to develop these spots‚ and those genetically predisposed to high blood sugar were 38 times more likely to develop the brain spots.
