Depression May be a Risk for Later Dementia
Razi Berry While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study led by UC San Francisco indicates that poor mental health may also take its toll on cognition. The research adds to a body of evidence that links depression with dementia, […]
Alzheimer’s Disease Linked to Certain Personality Traits
Razi Berry New research from the Florida State University College of Medicine found that changes in the brain associated with Alzheimer’s disease are often visible early on in individuals with personality traits associated with the condition. The study focused on two traits previously linked to the risk of dementia: neuroticism, which measures a predisposition for […]
New Diet – MIND Diet – Linked to Cognitive Performance
Razi Berry Aging takes a toll on the body and on the mind. For example, the tissue of aging human brains sometimes develops abnormal clumps of proteins that are the hallmark of Alzheimer’s disease. How can you protect your brain from these effects? Researchers at Rush University Medical Center have found that older adults may […]
The Future of Predicting Alzheimer’s Disease – 99% Accuracy
Razi Berry Researchers from Kaunas universities, Lithuania developed a deep learning-based method that can predict the possible onset of Alzheimer’s disease from brain images with an accuracy of over 99 per cent. The method was developed while analyzing functional MRI images obtained from 138 subjects and performed better in terms of accuracy, sensitivity and specificity […]
Cholesterol in Brain Regulates Alzheimer’s Plaquing
Razi Berry A team co-led by scientists at Scripps Research has used advanced imaging methods to reveal how the production of the Alzheimer’s-associated protein amyloid beta (Aβ) in the brain is tightly regulated by cholesterol. Appearing in Proceedings of the National Academy of Sciences (PNAS), the scientists’ work advances understanding of how Alzheimer’s disease develops […]
Brain Cell Lipid Balance Important Factor for Alzheimer’s
Razi Berry Alzheimer’s disease is predominant in elderly people, but the way age-related changes to lipid composition affect the regulation of biological processes is still not well understood. Links between lipid imbalance and disease have been established, in which lipid changes increase the formation of amyloid plaques, a hallmark of Alzheimer’s disease. This imbalance inspired […]
Worsening Symptoms in Alzheimer’s Disease Could be Due to Secondary Infections
Razi Berry New research into Alzheimer’s disease (AD) suggests that secondary infections and new inflammatory events amplify the brain’s immune response and affect memory in mice and in humans — even when these secondary events occur outside the brain. Scientists believe that key brain cells (astrocytes and microglia) are already in an active state due […]
Muscle Signals are Important to a Healthy Brain
Razi Berry How do different parts of the body communicate? Scientists at St. Jude are studying how signals sent from skeletal muscle affect the brain. The team studied fruit flies and cutting-edge brain cell models called organoids. They focused on the signals muscles send when stressed. The researchers found that stress signals rely on an […]
New Tests for Revealing Alzheimer’s Before Symptoms Begin
Razi Berry Researchers at the University of Gothenburg in Sweden, together with their colleagues at the Barcelona Beta Research Centre in Spain, the University Medical Centre in Ljubljana, Slovenia, and the University of Paris, have found new forms of tau protein that become abnormal in th very early stages of Alzheimer’s disease before cognitive problems […]
More to Alzheimer’s Than Genetics
Razi Berry The color of our eyes or the straightness of our hair is linked to our DNA, but the development of Alzheimer’s disease isn’t exclusively linked to genetics, suggest recently published findings from Baycrest Centre for Geriatric Care. First study published about Alzheimer’s disease among identical triplets In the first study published about Alzheimer’s […]
