Getting Better Sleep Could HELP Reverse Alzheimer’s (in mice)
Razi Berry Multiple studies in humans and mouse models indicate that sleep disruptions raise the risk of Alzheimer’s disease (AD) by increasing the accumulation of disease-relevant proteins such as amyloid-beta (A-beta) in the brain. In the current study, a team led by researchers at Baylor College of Medicine discovered that, in an animal model of […]
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 […]
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 […]
Scientist Raises Doubt on Benefit of Neuroelectrical Therapies
Razi Berry Brain stimulation with electrical current is becoming increasingly popular for treating a wide range of pathologies: depression, anxiety, developmental disorders and even Alzheimer’s disease. But a recent research study has put the effectiveness of these treatments into question – specifically, transcranial Direct Current Stimulation (tDCS). What is Transcranial Direct Current Stimulation (tDCS)? From […]
