Brain Sabotage: Alzheimer’s protein may spawn miniseizures

A sticky protein implicated in Alzheimer’s disease disrupts the brain’s circuitry by inducing seizures that give barely an outward sign that they’re happening, a study of mice shows.

Excessive buildup of a protein called amyloid-beta in the brain is a hallmark of Alzheimer’s disease, and scientists have long suspected that this protein plays a deleterious role in the disease.
