Subtle changes in brain activity in the presence of both amyloid-beta and tau proteins may point to Alzheimer's disease, long before symptoms appear, a new study indicates.
Two amyloid plaques from the brain of a patient with Alzheimer's disease. In this photomicrograph, neurites are darkly stained with the Naoumenko-Feigin silver method, and the pink elements (including the plaque cores) are stained with the periodic acid-Schiff (PAS) counterstain. The bar is 20 microns (0.02 mm) in length.
The causes of Alzheimer's disease remain poorly understood. [16] There are many environmental and genetic risk factors associated with its development. The strongest genetic risk factor is from an allele of apolipoprotein E. [17] [18] Other risk factors include a history of head injury, clinical depression, and high blood pressure. [1]
A main theory behind the cause of Alzheimer’s disease is the build-up of the protein amyloid-beta in the brain. Researchers from the University of Cincinnati provide evidence suggesting it’s ...
New research is contradicting previously held views that only neurons secret beta-amyloid that forms toxic plaques, a marker of Alzheimer's disease in the brain. The study points to another ...
The biochemistry of Alzheimer's disease, the most common cause of dementia, is not yet very well understood. Alzheimer's disease (AD) has been identified as a proteopathy : a protein misfolding disease due to the accumulation of abnormally folded amyloid beta (Aβ) protein in the brain . [ 1 ]
Amyloid beta (Aβ, Abeta or beta-amyloid) denotes peptides of 36–43 amino acids that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease. [2] The peptides derive from the amyloid-beta precursor protein (APP), which is cleaved by beta secretase and gamma secretase to yield Aβ in a cholesterol ...
“Amyloid deposition in the brain starts decades before the onset of Alzheimer’s symptoms. One study found that 44% of 90-year-olds with good cognitive function had amyloid pathology ,” Hara ...
