According to a new study published by Johns Hopkins Bloomberg School of Public Health, sleep quality may influence the onset and progression of Alzheimer’s disease. Lead author, Adam Spira, PhD, and his team of researchers discovered a link between shorter and/or poor sleep quality and higher levels of Amyloid beta build-up in the brain.“Amyloid beta is a peptide of 36–43 amino acids that is processed from the amyloid precursor protein (APP). While best known as a component of amyloid plaques in association with Alzheimer’s disease, as Aβ is the main component of certain deposits found in the brains of patients with Alzheimer’s disease, evidence has been found that Aβ is a highly multifunctional peptide with significant non-pathological activity.” Researchers observed self-reported
