BDNF and amnesia: Similarly, in scopolamine-induced amnesia, polyherbal formulations such as Divya-Medha-Vati, which includes CA among other phytochemicals, have been observed to reverse behavioral impairments, mitigate oxidative stress, and elevate the expression of neurotrophic genes (BDNF, NGF-1, SYN-1), suggesting that CA may facilitate the activation of neurogenic pathways in addition to its antioxidant properties [43].
