Low levels of amyloid-β and tau proteins, biomarkers of Alzheimer's disease (AD), in eye fluid were significantly associated with low cognitive scores, according to a new study. These findings indicate that proteins in the eye may be a potential source for an accessible, cost-effective test to predict future Alzheimer's disease.
Gum disease (gingivitis) that goes untreated can become periodontitis, causing loss in the bone that supports your teeth. Periodontitis is the main cause of tooth loss in adults. Periodontitis is also a risk factor for developing dementia. Recently, researchers in South Korea studied the connection between chronic periodontitis and dementia. They published their findings in the Journal of the American Geriatrics Society.
Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state NMR, University of Groningen Associate Professor Patrick van der Wel and colleagues from the University of Pittsburgh have discovered that the signal induced by cytochrome c is more controlled than expected. The results were published in the journal Structure.
A new treatment for a common type of stroke may soon be possible, thanks to a discovery by an international team of researchers led by the University of British Columbia.
By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown they can improve cognitive and memory impairments similar to those seen in Alzheimer's patients.
Findings could fundamentally change how scientists interpret the biological activities of serotonin.
Having a parent with Alzheimer's disease has been known to raise a person's risk of developing the disease, but new research suggests that having second- and third-degree relatives who have had Alzheimer's may also increase risk. The study is published in the March 13, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers have discovered a new potential contributor to age-related hearing loss, a finding that could help doctors identify people at risk and better treat the condition.
A James Cook University scientist is part of an international team that's used new 'big data' analysis to achieve a major advance in understanding neurological disorders such as Epilepsy, Alzheimer's and Parkinson's disease.
A major new study from the UC Davis Alzheimer's Center has uncovered dramatic differences in the brains of Hispanics with a dementia diagnosis compared with those of non-Hispanic whites and of African Americans.
