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.

(The study’s principal investigator, Bruce Yankner [center], with four laboratory employees | The Boston Globe)

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.

Model: Ten-month-old male EFAD mice 
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.

(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.
