Aged garlic extract prolongs longevity and improves spatial memory deficit in senescence-accelerated mouse

Area of Science:

• Gerontology
• Pharmacology
• Neuroscience

Background:

• Senescence-accelerated mouse (SAM) models exhibit accelerated aging phenotypes.
• Cognitive decline and reduced lifespan are characteristic of aging.
• Aged garlic extract (AGE) is explored for its potential health benefits.

Purpose of the Study:

• To investigate the effects of chronic aged garlic extract (AGE) administration on longevity.
• To evaluate the impact of AGE on spatial learning and memory in aging mice.
• To assess AGE's potential to mitigate age-related physiological decline.

Main Methods:

• Senescence-accelerated-prone mouse 8 (SAMP8) and senescence-accelerated-resistant mouse 1 (SAMR1) were fed a diet containing 2% AGE from 2 months of age.
• Survival ratios were monitored in both mouse strains.
• Spatial learning performance was assessed using the Morris water maze test in SAMP8 mice.

Main Results:

• Aged garlic extract (AGE) administration completely prevented the reduced survival ratio observed in SAMP8 mice.
• AGE significantly improved the learning deficits in SAMP8 mice within the Morris water maze test.
• SAMR1 mice, a control group, exhibited a higher survival ratio than untreated SAMP8 mice.

Conclusions:

• Aged garlic extract (AGE) demonstrates a significant positive impact on lifespan and cognitive function in aging mouse models.
• These findings suggest AGE possesses anti-aging properties and may counteract age-related memory impairments.
• Further research into AGE's therapeutic potential for human aging and cognitive disorders is warranted.
