Lower Blood Levels of Amyloid Beta 42 in Midlife Associated With Dementia Risk

Lower blood levels of amyloid-beta 42 during mid-life were associated with a higher risk of dementia and a marginally increased risk of mild cognitive impairment later in life, a new study reports.

Prevailing Alzheimer’s Theory in Question With New Discovery

Study finds amyloid-beta plaques may not be the cause of memory loss associated with Alzheimer's disease, but instead a consequence of the disease. Regardless of the levels of amyloid plaques, researchers found individuals with high levels of amyloid peptide were cognitively normal. Higher levels of soluble amyloid beta peptide were also linked to people having a larger hippocampus.

P-Glycoprotein Removes Alzheimer’s-Associated Toxin From the Brain

P-glycoprotein, a critical toxin pump in the body, has the ability to remove amyloid plaques from the brain. Researchers say increasing P-gp in the blood-brain barrier of those at risk for Alzheimer's could postpone or prevent the onset of the neurodegenerative disease.

Some Alzheimer’s Plaques May Be Protective, Not Destructive

Microglia creates dense-core plaques which help to clear away more wispy plaques from neurons, preventing cell death. Findings suggest the dense-core plaques play a defensive role in protecting the brain from the ravages of neurodegenerative diseases, such as Alzheimer's.

Unusual Mechanism in Rare Mutation Associated With Alzheimer’s Uncovered

The S198P mutation causes APP to fold more quickly, allowing amyloid-beta peptides to produce from mature APP at a more rapid rate than from APP that does not contain the genetic mutation. The findings shed new light on genetic mutations associated with Alzheimer's disease.
