Herpes Viruses Linked to Alzheimer’s Disease in New Brain Research

A fringe theory about the origins of Alzheimer’s disease—that latent viral infections can sometimes trigger its emergence—has gotten perhaps its most significant bit of support yet. A complex new study published Thursday in Neuron has found evidence that certain viruses are not only more common in the brains of people with Alzheimer’s, but that they play a direct role in the chain of events responsible for the fatal neurodegenerative disorder.

Maybe Our Brains Actually Can Grow Back Neurons

A new study published Thursday in Cell Stem Cell is set to further stoke the debate over whether our brain can actually grow back neurons as we age. The research found that people, even into their golden years, are regenerating their stock of neurons right up until the point of death—seemingly contradicting the results of a major study released just last month.

Signs of Alzheimer’s Detected in Brains of Chimps For First Time

Humans are the only animals known to develop Alzheimer’s disease, an age-related brain disorder that causes impaired cognitive functioning and other behavioral problems. Or at least, that’s what we thought. For the first time ever, researchers are claiming to have found signs of the disease in the brains of elderly chimps—a discovery that could yield new insights into the dreaded disorder.
