INFLAMMATION LINKED TO ALZHEIMER’S DISEASE
Exposure to inflammation early in life quadruples one’s risk of developing Alzheimer’s disease, said researchers in a presentation on June 19 at the first Alzheimer’s Association International Conference on Prevention of Dementia in Washington.
A research team led by Margaret Gatz, Ph.D. (a professor of psychology at the University of Southern California) and including researchers from the Karolinska Institute in Stockholm, Sweden, sifted through data on the 20,000 participants in the Swedish Twin Registry and found 109 "discordant" pairs of twins in which only one twin had been diagnosed with dementia.
Previous studies by Dr. Gatz and colleagues have shown that Alzheimer’s disease is strongly genetic; if one twin has the disease, his or her identical twin has a 60 percent chance of developing it.
Information about participants’ education, activities and health histories came from surveys they completed in the 1960s, when the registry was created, as well as from hospital discharge records. The surveys included questions about loose or missing teeth. Researchers used the answers to the dental-related questions to build a crude indicator of periodontal disease.
They concluded that an inflammatory burden early in life, as represented by chronic periodontal disease, might have severe consequences later. "If what we’re indexing with periodontal disease is some kind of inflammatory burden, then it is probably speaking to general health conditions," said Dr. Gatz.
If the link between inflammation and periodontal disease is confirmed, researchers said it would add inflammatory burden to the short list of preventable risk factors for Alzheimer’s disease.To learn how to treat gum disease long Island without surgery learn about laser periodontal therapy on Long Island
