Other studies have also demonstrated the neuroprotective effects of nutraceuticals against toxic compounds associated with neurodegenerative diseases via mechanisms such as modulation of energy metabolism, oxidative stress, neuroinflammation, and promotion of neurogenesis via growth factors and neurotrophins (Dadhania et al., 2016; Pandareesh et al., 2018). Here, BDNF is linked to neurodegenerative disease.
