DOI: 10.1016/j.envint.2024.108512Magnetite, a tiny particle found in air pollution, can induce signs and symptoms of Alzheimer’s disease, new research suggests. Alzheimer’s disease, a type of dementia, leads to memory...
by University College London Credit: Pixabay/CC0 Public DomainPeople at risk of Alzheimer’s disease have impaired spatial navigation prior to problems with other cognitive functions, including memory, finds a new study led by UCL researchers. The research, published in Alzheimer’s & Dementia, used virtual reality to test the spatial navigation of 100 asymptomatic midlife adults, aged 43-66,...
by Rutgers University Credit: Pixabay/CC0 Public DomainThe impact of abdominal fat on brain health and cognition is generally more pronounced in middle-aged men at high risk of Alzheimer’s disease than in women, according to researchers at Rutgers Health. In middle-aged individuals with a family history of Alzheimer’s disease, the amount of fat in their abdominal organs...

by Lauran Neergaard A closeup of a human brain affected by Alzheimer’s disease, is displayed at the Museum of Neuroanatomy at the University at Buffalo in Buffalo, N.Y., on Oct. 7, 2003. According to findings published Wednesday, Feb. 21, 2024 in the New England Journal of Medicine, Alzheimer’s quietly ravages the brain long before symptoms...
by Hong Kong University of Science and Technology The research team has developed a revolutionary blood test for Alzheimer’s disease (AD) that can measure the levels of 21 proteins in multiple crucial biological pathways. The test can also calculate an AD risk score, enabling the evaluation of an individual’s AD status. Credit: Hong Kong University of...
by Northwestern University Credit: Neuron (2024). DOI: 10.1016/j.neuron.2024.01.013A new Northwestern Medicine study has found the immune system in the blood of Alzheimer’s patients is epigenetically altered. That means the patients’ behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an...
by Kendall Daniels, University of North Carolina at Chapel Hill School of Medicine Credit: Wikimedia CommonsUNC School of Medicine researcher Sarah Cohen, Ph.D., and Ian Windham, a former Ph.D. student from the Cohen lab, have made a new discovery about apolipoprotein E (APOE)—the biggest genetic risk factor for late-onset Alzheimer’s disease. Older people who inherited a...
