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 ]
Brain Aβ is elevated in people with sporadic Alzheimer's disease. Aβ is the main constituent of brain parenchymal and vascular amyloid; it contributes to cerebrovascular lesions and is neurotoxic. [ 33 ] [ 34 ] [ 35 ] It is unresolved how Aβ accumulates in the central nervous system and subsequently initiates the disease of cells.
[22] [39] Although the number of neurofibrillary tangles correlates more strongly with the degree of dementia than does the number of plaques, genetic and pathological findings indicate that Aβ plays a central role in the risk, onset, and progression of Alzheimer's disease. [21] The diagnosis of Alzheimer's disease typically requires a ...
Scientists have spotted changes in brain activity that may point to Alzheimer’s. RapidEye/Getty Images ... the cause of Alzheimer’s disease includes the build-up of amyloid-beta and tau ...
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 ...
Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens. [2] It is the cause of 60–70% of cases of dementia. [2] [15] The most common early symptom is difficulty in remembering recent events. [1]
It is currently unclear as to whether or not primary age-related tauopathy (PART), a term in which includes some cases formerly referred to as neurofibrillary tangle-predominant dementia (NFTPD) or tangle-only dementia, is a variant of the traditional Alzheimer's disease, or a distinct entity.
“A study from 2019 reported that a woman carrying the presenilin 1 (PSEN1) mutation, a genetic cause of early-onset Alzheimer’s disease, did not develop dementia in her 40s as others with the ...
