This book presents a systematic and extensive understanding about metabolic alterations affecting multiple aspects of different neurodegenerative diseases (NDDs), such as Alzheimer’s, Parkinson’s, Huntington’s disease, SCAs, SBMA, DRPLA, ALS, Freidrich Ataxia etc. The book also illustrates  cellular and molecular mechanisms behind the key  neurodegenerative diseases and further expands on concept of unique and developing biomarkers associated with the onset and progression of NDDs. Additionally, it elaborates on the concept of latest imaging tools to monitor state of NDDs and accordingly develop therapeutic approaches entailing phytochemicals in the management of metabolic alterations associated with NDDs that ultimately suppresses course of devastating NDDs. The book aids to improve the overall understanding about the NDD and involvement of metabolic disorder as a major factor for indisposition of the disease. Therefore, suggesting that targetting metabolic variations by phytochemicals can combat NDD related symptoms for the betterment of impacted patients. While introducing cellular and molecular mechanisms and the treatment regimen under the umbrella of metabolism in several NDDs, the book covers major aspects of understanding the metabolic basis of NDDs, its implications, and treatment. This will inflate the readers' understanding about this particular area and guide those working in this domain, be it a researcher or clinicians,to choose or design effective therapeutic strategies to curb metabolic alterations linked with these disorders. This book will not only contribute towards improving the overall state of the challenged individuals but will also bring new hope towards improving the quality of lives of affected patients.
