In a revolutionary study, researchers have discovered that artificial intelligence could help detect Alzheimer's diseases from brain scans much before actual diagnosis happens. Researchers at UC said that by the time a definitive diagnosis is made for Alzheimer's, too many neurons are dead already, making it essentially irreversible.

So the researchers built a machine learning algorithm that studies brain scans to diagnose early-stage Alzheimer's before a clinical diagnosis could be made, Fast Company reported.
