Less Sleep More Brain Fog?


Researchers at the Johns Hopkins Bloomberg School of Public Health in Baltimore found that getting less sleep or sleeping poorly was tied to an increase in brain levels of beta-amyloid, a toxic protein that builds up and forms plaques in the brains of those with Alzheimer’s.

The researchers studied 70 older adults, average age 76, who were part of the ongoing Baltimore Longitudinal Study of Aging. Using brain scans, they found that those who said they got the least sleep, under five hours a night, or who slept fitfully had higher levels of beta-amyloid in the brain than those who slept over seven hours a night. The findings appeared in the journal JAMA Neurology.

    In my medical invittuie practice, I have often been consulted by family and friends of those whose parents or loved ones have been diagnosed with Alzheimer’s disease. The origin of this disease is unknown, however much attention is being placed upon the growth of Amyloid plaques in the brain.Amyloid plaques are waxy and translucent protein-polysaccharide complexes that are deposited in organs or tissues during certain diseases. These deposits cause the degeneration of the organ or tissue involved. Amyloid plaques are associated with a number of conditions including Alzheimer’s disease, Hodgkin’s disease and Osteomyelitis.’
