Current sleep patterns could help determine your risk of developing Alzheimer's disease as you age. People who experience more fragmented sleep and less non-REM slow-wave sleep are more likely to have increased levels of amyloid-beta. Read More
IFITM3, a protein that plays a role in the immune response to pathogens, also plays a key role in the accumulation of amyloid-beta plaques. As IFITM3 directly affects plaque formation, researchers suggest both viral and bacterial infections could increase the risk of Alzheimer's development. Read More
Early postmenopausal estrogen replacement therapy may protect some women from developing Alzheimer's disease. Read More
Study reveals a link between amyloid-beta accumulation in the brain and lower levels of insulin and insulin resistance. Read More
Analyzing nasal discharge could be a new tool in diagnosing and monitoring the progression of Alzheimer's disease. Researchers found certain Alzheimer's related proteins can be detected in nasal discharge. Read More
Salt crystals can precipitate at low concentrations due to local density fluctuations. Their repeated precipitation dissolution behavior promotes amyloid-beta peptide aggregation. Read More
Oxytocin, the so-called "love hormone," could help to treat cognitive disorders, including Alzheimer's disease. Researchers demonstrated oxytocin reversed the effects of amyloid-beta on hippocampal LTP in mice. The findings suggest oxytocin could be used as a therapeutic for the treatment of Alzheimer's disease and other dementias. Read More
PET neuroimaging reveals super-agers and those whose cognitive skills are above the norm for an advanced age have an increased resistance to tau and amyloid proteins. Read More
Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime. Read More
Tau spreads through the human brain via neural communication pathways. The spread is accelerated by the presence of amyloid-beta. Read More
A 3D human tissue culture model demonstrated a possible causal relationship between Alzheimer's disease and herpes simplex virus 1 (HSV-1) infection. 40 Alzheimer's associated genes were over-expressed in the HSV-1 infected brain tissue, including genes associated with the production of amyloid-beta. Read More
Researchers have developed a new approach to prevent amyloid plaque formation by engineering a nanodevice that captures the peptides before they can assemble. The silica nanodevice might be a new tool in the treatment and prevention of Alzheimer's disease and other neurodegenerative diseases associated with amyloid-beta. Read More
