APOE occurs in three common forms alleles: But APOE is also independently synthesized in brain astrocytes and, to a lesser extent in brain oligodendrocytes — and does not cross the blood-brain barrier.
More than denial, anosognosia is a lack of awareness of impairment — most people do not even know they are ill — and it affects up to 81% of those with Alzheimer’s disease. A Place for Mom recently had the opportunity to speak with the Treatment Advocacy Center to learn more about. Alzheimer's disease is the most common cause of dementia — a group of brain disorders that cause the loss of intellectual and social skills.

Cholesterol is an essential constituent of all cell membranes, which helps provide membrane fluidity. The human brain has high levels of myelin to facilitate axon conduction speed and information processing. Myelin is produced by oligodendrocytes.
Cholesterol allows for the tight packing of membranes seen in myelin sheaths.

APOE is the major lipoprotein for lipid transport in the cerebrospinal fluid and between cells in the brain tissue itself. APOE could serve to remove oxidized lipids including oxysterols from the brain. Having one rather than two APOE4 alleles is a risk factor for women, but not for men.
Individuals having both APOE4 alleles have been shown to have a smaller hippocampus.
APOE is normally secreted by astrocytes following neuronal damage. Vascular damage, inflammation and APP mobilization have been suggested as reasons for the correlation, but APOE synthesis normally increases several hundred-fold following nervous system injury.
High levels of cholesterol are associated with increased risk of AD. Apparently, the subcellular distribution of cholesterol affects amyloid-beta production. Cholesterol deposition on cerebral vessel walls can lead to ischemia. In any of these scenarios, AD is ultimately due to vascular disease.
Tau is mainly present in the axons of neurons. A number of kinases can phosphorylate add a phosphate to tau and a few phosphatases can dephosphorylate tau.
The phosphorylation state of tau affects the protein's ability to self-associate or bind microtubules. Heat shock proteins and the chaperone protein Pin1 can also affect tau properties.
NFTs develop most frequently in large pyramidal neurons with long cortical-cortical connections allowing for influence by amyloid plaques located some distance away.
Neuron death is due to NFTs or Lewy bodies — the role of amyloid plaque is at most indirect. Hyperphosphorylation of tau is critical for the formation of NFTs.
Acidic conditions such as exist in lysosomes and inflammation enhance amyloid-beta aggregation. During development, RAGE is a cellular receptor for amphoterina protein that mediates neurite outgrowth.

To help distinguish Alzheimer's disease from other causes of memory loss, doctors now typically rely on the following types of tests.
Government and other scientists are proposing a new way to define Alzheimer’s disease — basing it on biological signs, such as brain changes, rather than memory loss and .
