Tooth loss may be linked to memory-robbing condition, dementia
Baku, August 25 (AZERTAC). A new research has found a link between tooth loss and memory loss. The results of the study suggest that tooth loss may predict the development of dementia in aged people.
The new study, published online in `Behavioral and Brain Functions,` suggests that the elderly individuals who lose their teeth may be at an increased risk of experiencing memory loss or developing early stage Alzheimer`s disease.
Tooth loss linked to dementia
In the study, conducted in Japan, more than 4,200 individuals age 65 or older underwent a thorough dental examination and psychological assessment.
After the analysis, the study investigators found that those who had fewer of their own teeth were more likely to have experienced memory robbing condition dementia or have early-stage Alzheimer`s disease, the most common form of dementia.
The theory is that scientists believe infections in the gums can lead to tooth loss and may release substances, which in turn could enhance brain inflammation. And that may result in causing neurons to die and speed up memory loss.
The study also revealed that participants with symptoms of memory loss tended to report that they rarely or never went to the dentist, which may be one explanation for the study`s findings.
Gum disease may be the factor
But, study`s lead investigator, Dr. Nozomi Okamoto of Nara Medical University in Japan, suggested that there may be other factors that link tooth loss to memory problems, according to EmaxHealth.com.
“Infections in the gums that can lead to tooth loss may release inflammatory substances, which in turn will enhance the brain inflammation that cause neuronal death and hasten memory loss,” the health news website quoted Dr. Okamoto as saying.
“The loss of sensory receptors around the teeth is linked to some of the dying neurons.”
Gum disease is the major cause of tooth loss in elderly people.
According to Medical News Today, Chief Executive of the British Dental Health Foundation Dr Nigel Carter has expressed major concerns following the latest findings that linked tooth loss to dementia, saying the results add to the growing evidence that poor oral health and memory loss are related.
Dr Carter said: "This study only goes to strengthen the possible link between tooth loss and memory. Previous studies have suggested there might be a link between a low number of teeth and Alzheimer`s disease and baseline dementia and the case towards a possible link seems to be growing ever stronger."
"We already know that good oral health has a positive impact on overall health, and likewise, the evidence towards poor oral health and systemic links is mounting.
"Heart disease, strokes, diabetes, lung disease and pre and low weight babies have all been found to be linked with poor oral health. This latest research highlights yet another worrying risk factor of having poor oral health."
