Ashwagandha has been studied for its influence on cognitive function, particularly memory, attention, and executive processing under stress. Neurobiological research suggests that its withanolides may support neuronal communication by reducing oxidative stress and inflammation in brain tissue, mechanisms linked to cognitive decline and mental fatigue. These neuroprotective effects are not stimulatory but instead support baseline cognitive resilience, especially in individuals experiencing chronic stress or anxiety.

Clinical studies involving adults with mild cognitive impairment and high stress levels have shown improvements in reaction time, task performance, and memory consolidation after consistent ashwagandha supplementation. These outcomes are believed to result from reduced cortisol interference in hippocampal and prefrontal cortex function, areas critical for learning and decision-making. Importantly, improvements were observed without sedative effects or cognitive dulling. NIH – National Center for Biotechnology Information
Mood-related research indicates that ashwagandha may help regulate emotional balance by modulating neurotransmitter systems associated with stress and anxiety, including GABAergic signaling. Unlike pharmaceutical anxiolytics, ashwagandha does not appear to suppress emotional responsiveness but may instead support emotional stability and stress tolerance. This aligns with its traditional classification as a rasayana, or rejuvenating plant, in Ayurvedic medicine. NIH – National Center for Biotechnology Information
