   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 ]

   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 ...

   The study found that increased levels of both amyloid-beta and tau proteins in the brain may lead to changed brain activity before the cognitive symptoms of Alzheimer’s disease appear. Focusing ...

   Alzheimer's disease accounts for 60–70% of cases of dementia worldwide. The most common symptoms of Alzheimer's disease are short-term memory loss and word-finding difficulties. Trouble with visuospatial functioning (getting lost often), reasoning, judgment and insight fail. Insight refers to whether or not the person realizes they have ...

7. Amyloid beta - Wikipedia

   en.wikipedia.org/wiki/Amyloid_beta

   The other protein implicated in Alzheimer's disease, tau protein, also forms such prion-like misfolded oligomers, and there is some evidence that misfolded Aβ can induce tau to misfold. [6] [7] A study has suggested that APP and its amyloid potential is of ancient origins, dating as far back as early deuterostomes. [8]
