Tooth loss linked with dementia
Elderly people who lose their teeth may be at increased risk for dementia, new research reveals. The new study included more than 4,000 Japanese participants, 65 and older, who underwent a dental examination and a psychiatric assessment. Compared with participants who still had many of their natural teeth, those with fewer or no teeth were much more likely to have experienced some memory loss or have early-stage Alzheimer's disease. The findings were published online last month in Behavioral and Brain Functions. Participants with symptoms of memory loss tended to report that they had visited the dentist rarely, if at all.
