BACKGROUND: Blueberry anthocyanin extract (BAE) is a natural antioxidant flavonoid found in blueberries that has the potential to alleviate oxidative stress-induced neurodegeneration. Previous studies have demonstrated the potential of BAE to mitigate arsenic-induced cognitive impairment; however, the underlying protective mechanisms remain elusive. PURPOSE: This study aimed to evaluate the effectiveness of BAE in reducing arsenic-induced cognitive impairment and explored whether BAE's neuroprot...
