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.

(Case Western Reserve University | Cleveland 19)

Model: Young (2- to 4-month-old) and aged (9- to 10-month-old) C57Bl/6JR mice, APP/PS1 mice, and 5xFAD mice 
Dosage: 0.2 mg/mL of doxycycline in drinking water starting at least 7 days before surgery and ceased 2 days before the partial cellular reprogramming window for engram tagging, after which it was immediately reintroduced

Gene Therapy Restores Cognitive Function in Aging and Alzheimer’s Disease

Delivering a gene therapy targeting ensembles of neurons that store memories restores learning and memory capabilities in mouse models of aging and Alzheimer’s disease.

(The study’s principal investigator, Professor Johannes Gräff | 24 Heures)

A partial cellular reprogramming gene therapy targeting memory trace cells restores facets of learning and memory in aged mice and those modeling Alzheimer’s disease.

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.

A Harvard study suggests lower levels of lithium in the brains of patients with Alzheimer’s disease and that lithium supplementation may help preserve cognitive resilience.
