When cerebral amyloid angiopathy is present, the brain diverts most of the waste-removing fluid away from the glymphatic system.
Researchers report human growth hormone, prepared from human tissue prior to 1985, may have been contaminated with seeds of the amyloid beta protein. In a new study, researchers injected mice with the original c-hGH batches containing amyloid beta which seeded amyloid pathology, even decades after storage. Findings support the hypothesis that the Alzheimer's causing proteins can be transmitted to from contaminated materials.
Researchers report, in a number of cases, amyloid beta pathology may have been transmitted by contaminated instruments used in neurosurgeries up to three decades previously.
A new study provides evidence that a protein synonymous with Alzheimer's disease, amyloid beta, may have passed to a small group of people who were given human derived growth hormone treatments prior to the mid 1980's.
Researchers have discovered that amyloid peptides are harmful to the blood vessels that supply the brain with blood in Alzheimer's disease, thus accelerating cognitive decline by limiting oxygen-rich blood and nutrients.
