POOR DENTAL HEALTH MAY LEAD TO ALZHEIMER’S, STUDY SUGGESTS

Professor Stjohn Crean, Dean, School of Medicine & Dentistry said:

 


 

 

“Whereas previous studies have indicated a link between dementia and other bacteria and viruses such as the Herpes simplex virus type I, this new research indicates a possible association between gum disease and individuals who may be susceptible to developing Alzheimer’s disease, if exposed to the appropriate trigger! Research currently underway at UCLan is playing an active role in exploring this link, but it remains to be proven whether poor dental hygiene can lead to dementia in healthy people, which obviously could have significant implications for the population as a whole. It is also likely that these bacteria could make the existing disease condition worse.”

Dr. Sim K. Singhrao, Senior Research Fellow at UCLan said: “We are working on the theory that when the brain is repeatedly exposed to bacteria and/or their debris from our gums, subsequent immune responses may lead to nerve cell death and possibly memory loss. Thus, continued visits to dental hygiene professionals throughout one’s life may be more important than currently envisaged with inferences for health outside of the mouth only. To help us prove our hypothesis we are hoping to use the Brains for Dementia Research tissue resource to examine brain tissue from people with both intact and compromised memory who have relevant dental records. The future of the research aims to discover if P. gingivalis can be used as a marker, via a simple blood test, to predict the development of Alzhiemer’s disease in at risk patients.”
