Model: SAMP8 mice (5 months old) and C57BL/6 mice (16 months old)
Dosage: 1.5 mg/kg of urolithin A was administered by intraperitoneal injection three times per week (Monday, Wednesday, and Friday) for 8 weeks.

Study shows that urolithin A preserves memory and cognitive function during aging when treatment begins before age-related decline, but does not reverse cognitive impairment once it is established.

Brain &amp; Neurons

Duke University scientists have successfully induced new neuronal connections in the brains of mice, leading to improvements in social interaction and stress resilience. 

Advanced Alzheimer’s Can Be Reversed With NAD+ Restoration, Study Shows in Mice

Researchers at Case Western Reserve University have shown that late-stage neurodegeneration may be biologically reversible, at least in the right conditions, in mice.

Cognitive deficits were reduced by 52% in Alzheimer’s disease patients receiving transcranial magnetic stimulation (TMS) — a technique that stimulates the brain’s electrical activity. 


Lead researcher Giocomo Koch, MD, PhD, uses a TMS device on an individual wearing an electroencephalogram (EEG) cap (image: domussantarita.it). 

Participants: Middle-aged adults carrying two copies of the APOE4 gene 
Dosage: 1 mg/kg/day of rapamycin for 4 weeks

The prescription drug rapamycin a.k.a. sirolimus, an FDA-approved mTOR inhibitor, increases the brain volume of cognitively normal individuals at risk for developing Alzheimer’s disease.
