The complexity of the pathophysiology of cognitive dysfunction has led to the use of therapeutic strategies to combat the disease. Proper diet, cognitive activity, and regular physical exercise can significantly help in improving brain health with advancing age and potentially reduce the risk of cognitive decline. This book presents various neurological conditions and their amelioration using nutraceuticals and functional foods. Research studies in a number of phytopharmaceuticals and medicinal plants demonstrate their efficacy in boosting brain health and physical well-being as well as preventing the initiation and progression of several neurological disorders.
