Yale researchers have tested a new method for directly measuring synaptic loss in individuals with Alzheimer’s disease. The method, which uses PET imaging technology to scan for a specific protein in the brain linked to synapses, has the potential to accelerate research for new Alzheimer’s treatments, the researchers said.

Alzheimer’s disease affects 5.7 million Americans, and that number is expected to reach 14 million by the year 2050. To date, most of the research on the disease’s effects on the brain has been done postmortem. To investigate new treatments, researchers have recently explored methods for measuring memory loss in living patients.
