the combination of AlCl3 with D-galactose. The aqueous extract of HE prevents the further progression of AD by its neuroprotective potential. Behavioral abnormalities were also improved by the aqueous extract of HE in the AD mouse model. In a dosedependent manner, HE is responsible for the enhancement of choline acetyltransferase (ChAT) and acetylcholine (Ach) in serum and hypothalamus. To avert the pathogenesis of AD, the hypothalamus and serum level of Ach and ChAT is very vital. HE could be an efficient neuroprotective agent in AD and for some other neurodegenerative diseases [22]. For the treatment of different diseases, Coriolus versicolor (CV) mushroom is also widely utilized as a nutritional supplement. The oxidative stress and neuroinflammation were considerably reduced by the CV in AD. CV also improve the quality of mitochondria and restores the normal redox balance [92]. Human wellness was effectively maintained by the bioactive molecules present in prebiotics such as legumes [93–95], spirulina [96], biological nanoparticles [93, 97], mushroom [30]. Similar to PD, some herbal plants like *Bacopa monnieri, Withania somnifera, Eclipta alba, Moringa oleifera* and cucumber also improves cognitive function as suggested by some researchers [98–103]. In addition, the neuroinflammatory pathways are also significantly modulated by a variety of medicinal mushrooms in AD [104]. In Huntington's disease (HD), the therapeutic efficacy was also shown by medicinal, non-edible, and edible mushrooms and their bioactive components. Cognitive dysfunction is the very basic clinical feature of HD. In the edible mushroom Polyozellus multiplex, Polyozellin is a very important biomolecule having significant therapeutic activity. In the HD model, glutamate-induced mouse hippocampal neuronal HT22 cell death was significantly ameliorated by Polyozellin by apoptosis and the MAPK pathway. In HT22 cells, biochemical anomalies like lipid peroxidation and reactive oxygen species (ROS) were reduced by Polyozellin. Therefore, Polyozellin might be utilized for the treatment of HD patients in near future [105]. In the animal model of multiple sclerosis (MS), the disease conditions were ameliorated by Piwep, a mushroom extract from Phellinus igniarius. The dietary mushrooms and their bioactive components also improve the disease pathology in MS as with other NDs [106]. NFjB and Nrf2 mediated neuroinflammatory pathways are mainly responsible for mitochondrial dysfunction and ultimately cause progressive neurodegeneration in all NDs. Thus, the biomolecules of mushrooms play a very potential role to reduce the pathogenesis associated with NDs. Further studies will need to characterize more biomolecules in mushrooms and test their efficacy in several NDs.
