Researchers report Alzheimer's disease and other neurodegenerative disorders can be confirmed in living patients by specific biomarkers in cerebrospinal fluid.
People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
Lower serum levels of the sugar metabolite GlcNAc was associated with progressive disability and neurodegeneration in patients with multiple sclerosis.

Older women tended to have poorer memory fluidity scores than men of the same age group. However, the reverse was true for younger women. Researchers propose the difference could be a result of younger women having more access to higher education than previous generations.
Using over a century of data from other pandemics, and applying knowledge about the current COVID-19 infection, researchers predict the long term effects coronavirus will have on the brain and nervous system.
Activating group 2 innate lymphoid cells in aging brains helps improve memory in mice. The findings could help in the development of treatments for neurodegenerative diseases associated with aging.
