Natural polyphenols as therapeutic candidates for mitigating neuropsychiatric symptoms in post-traumatic stress...

Post-traumatic stress disorder (PTSD) is a challenging mental health condition that affects millions of people worldwide after they experience traumatic events. The current medications often do not fully address the wide range of PTSD symptoms or the underlying brain mechanisms, prompting the need to explore new treatments. Polyphenols, which are natural compounds found in many plant-based foods, have gained interest due to their brain-protective, anti-inflammatory, and antioxidant benefits. This review looks at how polyphenols might help treat PTSD by influencing important brain pathways related to the disorder. We explored how polyphenols affect the stress-response system, fear-related memories, brain chemicals, and inflammation. Specifically, we discuss how compounds like resveratrol, curcumin, green tea extract, and quercetin can balance stress hormones, help reduce fear memories, regulate brain chemicals, and decrease brain inflammation. Studies with animals have provided insights into how these compounds might work to ease PTSD symptoms. Based on the preclinical studies, the present review suggests that polyphenols could be a valuable addition or alternative to current PTSD treatments. However, more research is needed to confirm these findings and to determine the best ways to use polyphenols in treating PTSD.
