Mitochondria-Made Molecule Reverses Memory Loss with Advanced Age

A naturally occurring compound, α-lipoic acid, helped elderly mice think like younger mice by restoring energy balance and calming brain inflammation, according to Second Hospital of Hebei Medical University researchers.

Brain &amp; Neurons

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.

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.

Participants: Healthy middle-aged adults 
Dosage: 1200 mg/day of NR for 4 weeks

NR (nicotinamide riboside) raises blood NAD+ (nicotinamide adenine dinucleotide) levels more than NMN (nicotinamide mononucleotide) in healthy adults.

Johns Hopkins Research Review: Parkinson’s Drug Extends Multiple Species' Lifespan

L-deprenyl, a drug used to treat Parkinson’s disease and major depressive disorder, has been shown to modestly extend lifespan across species, from mice to rats to hamsters.

L-deprenyl, a drug prescribed to treat Parkinson’s disease and major depressive disorder, has been shown to modestly extend average lifespan across mammalian model organism species.
