Imagine reversing the course of conditions like Alzheimer’s or multiple sclerosis, in which cells of the central nervous system stop working or die. Researchers at Johnson & Johnson are hot on the trail of innovative solutions that may do just that, preventing often-debilitating symptoms along the way.

It’s the sixth leading cause of death in the United States, with no existing cure. But these researchers are committed to finding better ways to diagnose, treat and prevent the debilitating disease, using everything from innovative biomarker tracking to a potential vaccine for early stage patients.

Diagnostic tests. Clinical trials. A vaccine. For Alzheimer’s Awareness Month, we sat down with scientists at Janssen Research & Development to learn how their work has the potential to alter the future of how we detect and treat the disease.
