Strawberry Compound Fisetin Slows Cognitive Decline of Aging in Mouse Study
Researchers fed the antioxidant fisetin, found in strawberries and other fruits and vegetables, to mice for seven months and found that the compound partially protected the animals from age-associated cognitive decline. Fisetin’s effects correlated with the restoration of neuronal function and less brain inflammation. The results, which follows previous work with fisetin on a mouse model of Alzheimer’s disease, were reported in a study titled, “Fisetin Reduces the Impact of Aging on Behavior and Physiology in the Rapidly Aging SAMP8 Mouse,” published in the Journals of Gerontology Series A. Age-associated neurological diseases such as Alzheimer’s disease arise from genetic and environmental factors, but also from injuries to brain cells that accumulate with aging. Therefore, to reach an effective treatment, the Salk Institute researchers looked for compounds that might slow down age-related processes. They selected the natural flavonoid fisetin based on previous results showing the compound’s ability to prevent memory loss in Alzheimer's mice. The scientists extended their studies to mice that exhibit a progressive, age-associated decline in brain function similar to human Alzheimer's patients: the SAMP8 mouse. The Salk team fed 3-month-old prematurely aging mice a daily dose of fisetin with their food for seven months. They performed several memory and activity testes and compared their performance with mice fed the same food without fisetin. Researchers also examined levels of specific proteins related to neuronal function and in
