New study shows Alzheimer’s disease can be reversed to achieve full neurological recovery—not just prevented or slowed—in animal models | CWRU Newsroom | Case Western Reserve University For more than a century, people have considered Alzheimer's disease (AD) an irreversible illness. Consequently, research has focused on preventing or ...

“The pharmacological approach in this study, however, uses a pharmacologic agent (P7C3-A20) that enables cells to maintain their proper balance of #NAD+ under conditions of otherwise overwhelming stress, without elevating NAD+ to supraphysiologic levels.” #ISOGG #DNA case.edu/news/new-stu...

Brain activity associated with breakthrough food preoccupation in an individual on tirzepatide - Nature Medicine This study provides the first evidence in humans that tirzepatide modulates brain electrophysiology, with changes in low-frequency accumbens power linked to food preoccupation.
