One type of brain cell may invite Alzheimer's

Better tactics for detecting, preventing and treating Alzheimer's disease depend on a clearer understanding of cellular-level changes in the minds of patients, and a new study has uncovered novel details about the vulnerability ...

Neurons with good housekeeping are protected from Alzheimer's

Some neurons in the brain protect themselves from Alzheimer's with a cellular cleaning system that sweeps away toxic proteins associated with the disease, according to a new study from Columbia University and the University ...

Blood test for tau, Alzheimer's disease under development

Today, the only way to definitively diagnose Alzheimer's disease in life is through brain scans and tests of cerebrospinal fluid that must be collected via lumbar puncture. Though cumbersome and expensive, such tests provide ...

New information on the pathological mechanisms of Alzheimer's disease

Researchers at the University of Helsinki have discovered a mechanism by which harmful tau protein aggregates are transmitted between neurons. Alongside amyloid plaques, tau aggregates in the brain are a significant factor ...

Probing the pathology of impaired cognition

Neurofilament light (NFL) is a support protein within large axons in the brain's white matter that supports nerve signal transmission. When axons are injured, increased NFL concentrations are found in the cerebrospinal fluid ...

Zombie cells found in brains of mice prior to cognitive loss

Zombie cells are the ones that can't die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. And with a new letter in Nature, ...
