Harvard Study: A Low Dose of Lithium May Preserve Cognitive Resilience with Age

Researchers uncover significantly lower brain lithium levels in Alzheimer’s disease patients, and supplementing with a low-dose lithium salt restores memory in an Alzheimer’s disease mouse model.

Dosage: 14.4 ppm of alfatradiol in diet for five months

USC Study: Longevity-Promoting Drug Counteracts a Genetic Predisposition to Alzheimer's

The drug alfatradiol, also known as 17ɑ-estradiol, reduces cognitive errors on a test of memory and lowers neuronal plaques in mice genetically predisposed to Alzheimer’s disease.

Researchers unveil data suggesting the drug alfatradiol improves signs of frailty, reduces cognitive errors, and reduces neuronal plaques in mice with a genetic predisposition to Alzheimer’s disease.

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). 

The most comprehensive brain model reveals that combining NAD+ (nicotinamide adenine dinucleotide) supplementation with diet and exercise powerfully modulates brain aging.
