Brushing teeth, using floss, getting the teeth cleaned regularly by the dentist can go well beyond mere dental care; it can actually postpone the onslaught of Alzheimer’s disease.

According to a new study by Norwegian scientists, gum disease (gingivitis) can affect nerve cells in the brain, leading to memory loss and Alzheimer’s. The study team has discovered DNA-based proof to this link.

According to researcher Piotr Mydel, who works with the Department of Clinical Sciences in University of Bergen, the bacteria that cause gingivitis can move to brain, where the protein produced by them destroys the nerve cells, resulting in such memory loss.

The study, published in the journal, Science Advances, involved examining 53 people with Alzheimer’s. And 96 percent of them were found to have the harmful enzymes excreted by bacteria.

Piotr Mydel says that though bacteria alone won’t cause Alzheimer’s, their presence in the brain raises the risk of the disease and exacerbates the condition. Fortunately, the process can be slowed down with a proper dental care, avoiding gingivitis.

If you have gingivitis and there are people with Alzheimer’s in the family, Brush your teeth, use floss and go to your dentist regularly and get your teeth properly, Mydel advises.


Virtual Reality can help treat dementia, says a study

People with dementia have difficulty accessing past memories, which impacts their behaviour and relationship with others. Now a new study using Virtual Reality (VR) promises help to recall memories, which could bestow multiple benefits on such people. The findings are published in the journal, Proceedings of the SIGCHI Conference on Human Factors in Computing Systems.

The study was conducted on 8 dementia patients aged between 41 and 88, wherein each of them was given a VR headset and told to ‘visit’ a virtual environment (VE) selecting from the group of five VEs comprising a forest, a sandy beach, a rocky beach, a cathedral, and a countryside scene.

There were a total of 16 sessions. Based on the feedback from patients and their caregivers, it was found that the patients could recall old memories. For instance one of them remembered a holiday upon seeing a bridge while another recalled a holiday upon sighting a market in the VEs.

The findings show that new stimuli can jog old memories that are otherwise inaccessible due to dementia or a secure environment.

According to the researchers, VR can bring positive benefits to dementia patients, and make the quality of their life richer and more satisfying vis-à-vis their families and caregivers. Patients can be treated with customized 360-degree VEs, specific to individuals for better results.
