This book provides a comprehensive exploration of the role of plant-based medicines, or phytomedicine, in the prevention and treatment of neurodegenerative disorders. It delves into how various phytochemicals can modulate key biological pathways involved in diseases like Alzheimer's, Parkinson's, and other neurodegenerative conditions. The chapters highlight the importance of phytopharmacological agents, such as polyphenols, curcumin, and resveratrol, in targeting oxidative stress, protein aggregation, and inflammation. Later, a few chapters discuss how polyphenols help protect mitochondria, and some explore curcumin's role in regulating the mTOR and autophagy pathways. This book is an excellent resource for researchers in neuroscience, pharmacology, and natural medicine, as well as practitioners seeking holistic approaches to neurological health.
