A new study confirms that a simple blood test can reveal whether there is accelerating nerve cell damage in the brain. The researchers analysed neurofilament light protein (NFL) in blood samples from patients with Alzheimer’s disease.
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.
Salk research focuses on the development of compounds that may protect against the diseases of aging, such as Alzheimer’s
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.
Diagnosing Alzheimer's disease can be difficult, as several other conditions can cause similar symptoms. Now a new brain imaging method can show the spread of specific tau protein depositions, which are unique to cases with Alzheimer's.
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.
