Sept. 24 (UPI) -- In a finding that could change the way Alzheimer's disease is treated, researchers have identified a brain biomarker that could allow the condition to be detected decades before symptoms appear.
The discovery by a team led by Colombian neuroscientist Francisco Lopera -- working with the Neuroscience Group at the University of Antioquia and Florida International University in Miami -- could give millions of patients advance warning.
The marker, known as translocator protein, or TSPO, is linked to brain inflammation that precedes cognitive decline. Researchers say its active presence could serve as an early warning signal, especially in people with a genetic predisposition.
"This discovery brings us closer to preventive medicine for Alzheimer's. It's not just about treatment, but anticipation," Lopera said.
