Study suggests loss of blood vessels in retina reflect changes in brain health
Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tübingen now show that a protein found in the blood can be used to precisely monitor disease progression long before first clinical signs appear.
UB researchers corrected synaptic dysfunctions in the brain involved in memory loss, using an epigenetic approach
One of the hallmark traits of Alzheimer’s disease, a debilitating disorder marked by memory deficits and general cognitive decline, is the accumulation in the brain of a protein called b-amyloid. These proteins form “plaques” and bind to unique proteins on the surface of brain cells called receptors, causing widespread cell death.
Analysis of large data sets from post-mortem brain samples of people with and without Alzheimer's disease has revealed new evidence that viral species, particularly herpesviruses, may have a role in Alzheimer's disease biology.
