Periodontitis is associated with Alzheimer’s disease and other forms of dementia. Deteriorated cognition and motor control loss in Alzheimer’s can contribute to poor oral hygiene as it can be difficult to remember and perform sufficient oral hygiene.
A study published by Mydel from the University of Bergen, Norway, in Science Advances 1/2020, shows that good oral hygiene can slow down the rate of development of Alzheimer’s. Porphyromonas gingivalis (P. gingivitis) is a bacterium that causes chronic periodontitis and this has been found in the brains of Alzheimer’s patients. Several studies have previously concluded that infection contributes to the disease. Optimal oral hygiene is important for people with gingivitis and a family history of Alzheimer’s. In addition, one should follow a balanced diet, have an active lifestyle, get enough sleep, reduce stress, participate in social activities and stimulate brain activity. There is no cure for Alzheimer’s disease.
