The authors propose that the shots might keep the immune system primed to battle diseases that would otherwise contribute to cognitive decline.

The gene, aquaporin-4, is critical in rodents for the cerebrospinal fluid bath the brain gets during sleep. It’s now also tied to slow wave electrical activity during deep sleep in people.

Digital biomarkers of cognitive decline could alert us to the early stages of dementia before irreversible damage occurs.

After an accident as a teenager, he developed the disorder. He then studied the brain to better understand his own seizures, and now plans to sail around the world to show others with the condition how to push their limits.

While the findings contradict previous studies that have linked human herpesvirus 6 to the neurodegenerative disease, they do not eliminate the possibility of a relationship.

The 58-year-old was best known for uncovering evidence of a link between pathogens and the neurodegenerative disease.

Nurturing ideas to fruition, like growing plants, is a complex process that relies on a suitable substrate and favorable growth conditions.

A look at some of the circulating molecules that may indicate various Alzheimer’s pathologies and serve as the bases of noninvasive tests for the disease.

Researchers hope circulating biomarkers will enable earlier detection and better monitoring of the neurodegenerative disorder—and perhaps help usher in new treatments.
