Scientists Reverse Advanced Alzheimer’s Decline in 2 Mouse Models by Restoring NAD+ Balance
2 articles · Updated · mindbodygreen · May 13
P7C3-A20 restored physiological NAD+ levels in two advanced Alzheimer’s mouse models, and the animals recovered memory performance to match healthy controls.
The treatment also reversed tau phosphorylation, brain inflammation, oxidative stress, blood-brain barrier damage and impaired neurogenesis, suggesting neurons were dysfunctional rather than irreversibly lost.
Human brain tissue showed the same pattern: more severe Alzheimer’s tracked with greater disruption in NAD+ metabolism, while some people with Alzheimer’s pathology but intact cognition appeared to preserve NAD+ balance.
The Cell Reports Medicine study was not a human trial, but it points to NAD+ homeostasis as an upstream target that could reshape how researchers approach Alzheimer’s progression and treatment.
If Alzheimer's is a reversible energy crisis, how close are we to a treatment that can actually restore lost memories?
With new research on NAD⁺ boosters, what is the 2026 verdict on supplements like NR for protecting your brain?
P7C3-A20 Enables Full Cognitive Recovery in Advanced Alzheimer’s Mouse Models via NAD+ Restoration
Overview
In late 2025 and early 2026, groundbreaking studies transformed the understanding of Alzheimer’s disease by showing that advanced pathology could be reversed in animal models. This challenged the long-held belief that Alzheimer’s is irreversible. Researchers discovered that severe declines in NAD+ levels are directly linked to the neurodegeneration and cognitive decline seen in Alzheimer’s. By restoring NAD+ balance, they were able to counteract disease progression. These findings offer new hope for treatment, suggesting that damage from advanced Alzheimer’s may not be permanent and could potentially be undone.
