by Ben-Gurion University of the Negev VDAC1 is highly expressed in the neuropil surrounding the Aβ plaques of the 5 × FAD mouse model. a–d Representative cortical and hippocampal sections from WT and 5 × FAD mice treated and untreated with VBIT-4, IHC stained for Aβ (a, b) or VDAC1 (c, d). Higher magnifications of selected areas are shown...

Big data initiative discovers new causal pathways in Alzheimer’s
by King’s College London Flowchart of study design. CTL, cognitively normal controls; MCI, mild cognitive impairment; AD, Alzheimer’s disease; Aβ, β-amyloid; CSF, cerebrospinal fluid; A, amyloid pathology; T, tau pathology; N, neurodegeneration; PRS, polygenic risk score; MR, mendelian randomization. Credit: Alzheimer’s & Dementia (2023). DOI: 10.1002/alz.12961 A new study, published on Feb. 15 in Alzheimer’s & Dementia, analyzed...
New hope for first treatment for strokes linked to dementia
by University of Nottingham Credit: Pixabay/CC0 Public Domain Two cheap and common drugs could be re-purposed as the first specific treatment for people who experience a type of stroke linked to nearly half of all dementias, according to the results of new research. A clinical trial run by the University of Nottingham and University of Edinburgh...
Overlooked tau-RNA interaction may play key role in dementia
by University of Washington This antibody staining experiment shows tau-RNA complexes that have been dyed green. The tau-RNA complex staining strongly resembles neurofibrillary tangles, a hallmark of most kinds of dementia. Credit: Pamela J. McMillan Sometimes in science, “Eureka!” moments happen with surprisingly little effort. Sometimes they take years or decades to emerge. Such was...

Weight loss may be early predictor of Alzheimer’s disease in those with Down syndrome
by Charlene N. Rivera-Bonet, University of Wisconsin-Madison Credit: Unsplash/CC0 Public Domain Unintentional weight loss in people with Down syndrome may predict the onset of Alzheimer’s disease long before typical cognitive symptoms like memory loss and dementia are apparent. As many as 90% of people with Down syndrome experience Alzheimer’s symptoms by the time they are...
Controlling excess weight could lead to improved health outcomes, slow cognitive decline

Hormone replacement therapy could ward off Alzheimer’s among at-risk women
by University of East Anglia Credit: Pixabay/CC0 Public Domain Hormone Replacement Therapy (HRT) could help prevent Alzheimer’s Dementia among women at risk of developing the disease—according to University of East Anglia research. The study shows that HRT use is associated with better memory, cognition and larger brain volumes in later life among women carrying the APOE4...
Researchers find accumulation of amyloid beta protein at sites of potassium depletion in the brain
by University of Bristol Potassium isotope compositions of minipig brain regions indicate heavy K isotope enrichment coincident with amyloid beta accumulation, suggesting a mechanistic linkage and potential for downstream signal transferal to blood serum (i.e. noninvasive diagnostic potential). Credit: Metallomics (2022). DOI: 10.1093/mtomcs/mfac090 New research from a James Cook University-led study has proposed a hypothesis that higher levels of...
Does social isolation affect older adults’ risk of developing dementia?
by Wiley Credit: CC0 Public Domain New research published in the Journal of the American Geriatrics Society indicates that social isolation is common among older U.S. adults, and it increases their likelihood of developing dementia. Among 5,022 participants of the National Health and Aging Trends Study, a longitudinal and nationally representative study of older adults in the United States,...
