Story at-a-glance

  • Dental health is associated with hippocampal atrophy — shrinkage of the hippocampus brain region that serves as a marker for Alzheimer’s disease
  • People with mild gum disease and fewer teeth had a faster rate of shrinkage in the left hippocampus; having one less tooth increased brain shrinkage at a rate equivalent to nearly one year of brain aging
  • For those with severe gum disease, having more teeth was linked to a faster rate of brain shrinkage, with one more tooth akin to 1.3 years of brain aging
  • Porphyromonas gingivalis (P. gingivalis), a pathogen involved in chronic periodontitis, has been identified in the brains of patients with Alzheimer’s disease
  • Even in young, otherwise healthy, adults, episodic memory and learning rate is improved among those without good oral health compared to those with aggressive periodontal disease

Dementia has been added to the long list of health problems potentially associated with poor oral health. The finding, published in Neurology,1 suggests dental health is associated with hippocampal atrophy — shrinkage of the hippocampus brain region that serves as a marker for Alzheimer’s disease.2

A major new study suggests it’s possible to avoid developing dementia — here are 5 ways to reduce your risk

Via Marketwatch

Participants with high genetic risk and an unfavorable lifestyle were almost three times more likely to develop dementia versus those with a low genetic risk and favorable lifestyle.

Living a healthy lifestyle could help you reduce your risk of dementia, even if you have a genetic risk of the disease, a new study published in the peer-reviewed health journal JAMA found. The study analyzed data from 196,383 adults of European ancestry aged 60 and older. Of that sample, the researchers identified 1,769 cases of dementia over a follow-up period of eight years.

Here’s what they found: Participants with high genetic risk and an unfavorable lifestyle were almost three times more likely to develop dementia versus those with a low genetic risk and favorable lifestyle. However, the risk of dementia was 32% lower in people with a high genetic risk if they had followed a healthy lifestyle, compared to those with an unhealthy lifestyle.

Scientists Discovered What Causes Dementia

Via Big Think

Scientists discovered a major cause of dementia which can help in the diagnosis and treatment of the illness. The researchers point to toxic levels of urea in the brain as being responsible for the brain damage that leads to dementia, an incurable neurodegenerative disease that causes an impairment of memory and thinking abilities.
