Does Ashwagandha affect brain health?

Ashwagandha can have a positive impact on brain health through several mechanisms:

Reducing stress and anxiety: Ashwagandha is an adaptogen, which helps the body adapt to stress. It works by regulating the hypothalamic – pituitary – adrenal (HPA) axis, thus reducing the production of stress hormones like cortisol. High levels of cortisol can have a negative impact on the brain, affecting memory and cognitive function. By reducing cortisol levels, Ashwagandha helps to improve mood and cognitive performance and may even help prevent stress – related mental health disorders such as anxiety and depression.

Enhancing cognitive function: Some studies have suggested that ashwagandha may improve cognitive function. In a double – blind, placebo – controlled study, healthy adults who took Ashwagandha extract for 8 weeks showed significant improvements in measures of attention, information processing speed, and episodic memory compared to those who took a placebo. The extract may work by increasing blood flow to the brain or by protecting brain cells from oxidative stress.

Protecting against neurodegenerative diseases: Oxidative stress and inflammation play key roles in the development of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Ashwagandha has antioxidant and anti – inflammatory properties, which may help protect brain cells from damage caused by free radicals and inflammation. In pre – clinical studies, Ashwagandha has been shown to reduce amyloid – beta plaques and tau tangles in animal models of Alzheimer’s disease, suggesting that it may have a protective effect against the development of the disease.

Overall, while the current evidence suggests that Ashwagandha can have beneficial effects on brain health, more research is needed to fully understand its mechanisms of action and to determine the optimal dosage and duration of use.
