Abstract

Resveratrol may activate multiple neuroprotective pathways at plasma concentrations (1-10 μmol/L) achievable in humans.

Resveratrol is associated with the activation of SIRT1 and stimulation of AMPK, which are linked to neuroprotection.
It inhibits mTORC1, restores the process of cellular cleanup, and promotes the growth of new mitochondria, which are essential for energy production.
Preclinical evidence suggests it enhances brain-derived neurotrophic factor (BDNF) signaling, supports the formation of new neurons in the hippocampus, and reduces brain inflammation and damage from amyloid-beta and tau proteins.
In clinical trials, resveratrol has been linked to improved cognitive function and brain connectivity, though results have varied.
Its established safety profile and enhanced absorption suggest potential for use in addressing age-related cognitive decline.

Simplified

Age-related cognitive decline and neurodegenerative disorders present significant challenges in neuropsychiatry, as current therapeutic strategies largely fail to adequately address the complexities of cerebral aging. Resveratrol, a natural polyphenol, has become a promising multi-target neuroprotective agent that can affect multiple important pathways that are involved in aging and neurodegeneration at the same time. This review consolidates evidence indicating that resveratrol, particularly through bioavailability-enhanced formulations, activates SIRT1, stimulates AMPK, inhibits mTORC1, restores autophagic flux, and promotes mitochondrial biogenesis at plasma concentrations (1-10 μmol/L) achievable in humans. Preclinically, resveratrol augments BDNF-TrkB-CREB signaling, facilitates hippocampal neurogenesis, diminishes amyloid-β and tau pathology, and alleviates neuroinflammation and glial senescence. In clinical research, resveratrol has been associated with enhanced cognitive function and hippocampal connectivity in certain trials, as well as reduced inflammatory and metabolic markers associated with brain aging, although findings remain inconsistent. Resveratrol has emerged as a potential multi-target neuroprotective agent for mitigating age-related cognitive decline, owing to its proven safety record and enhanced pharmacokinetic properties. We asserted that the accumulated evidence necessitates the initiation of extensive randomized controlled trials in middle-aged and elderly individuals to assess its efficacy in maintaining cognitive function, alleviating brain aging, and delaying the onset of neurodegenerative diseases.
