Model: C57BL/6J mice, J20 mice, and 3xTg mice 
Dosage: 4.3 μEq l−1 of lithium in drinking water starting at 10 to 12 months of age and continued for 10 to 14 months during aging

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.

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.

(The University of Southern California | College Matchpoint)

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.
