Shingles Shots, NAD+ Science, and Speed Games: Three Unrelated Brain Boost Hype Cycles Emerge

Post date: February 26, 2026 · Discovered: April 17, 2026 · 3 posts, 31 comments

Preclinical research shows NAD+ restoration using P7C3-A20 can reverse Alzheimer's disease in advanced mouse models, achieving full cognitive recovery, according to reports in Cell Reports Medicine.

The discussion is fractured across three axes. Some users like happybadger pointed to the reversing potential of NAD+ therapy. Others focused on shingles vaccines, citing Powderhorn's observation that vaccinated seniors show lower dementia risk, potentially due to reduced inflammation. Separately, yogthos noted that speed training benefits were specifically tied to speed, not general memory improvement, suggesting differential brain engagement.

The community has no single view. Opinions are split between the profound scientific potential for reversing AD versus immediate vaccine efficacy claims. Meanwhile, critics dismiss some information outright, while proponents focus on the distinct mechanisms—be it metabolic repair, inflammation control, or executive speed.

Key Points

SUPPORT

Shingles vaccines may lower dementia risk by reducing inflammation.

Powderhorn noted older adults with the shingles vaccine show a reduced dementia risk.

SUPPORT

Restoring NAD+ levels can reverse Alzheimer's in mice.

happybadger cited a study showing P7C3-A20 treatment reverses AD in mouse models.

SUPPORT

Speed training benefits are separate from general memory gains.

yogthos argued measurable results specifically linked to speed training, not general reasoning.

OPPOSE

Claims about dementia prevention via vaccines lack verifiable source integrity.

One user dismissed the source material as 'Assumed Intelligence slop'.

SUPPORT

Reversing AD in mice does not guarantee human success.

happybadger warned that human clinical trials are necessary to validate the mouse efficacy.
