The diseases which are caused by the loss of function and eventual death of nerve cells in the brain or the peripheral nervous system are termed as neurodegenerative disorders. There are various mechanisms due to which neurodegenerative diseases can occur, such as genetic mutation accumulation of misfolded proteins, mitochondrial dysfunction and aggregation of proteins. A few of the neurodegenerative diseases are Alzheimer’s, Huntington’s and Parkinson’s disease. Alzheimer’s disease causes the patients to lose their memory over a period of time. Huntington’s disease causes the degeneration of nerve cells in the brain. It can result in disorders related to movement, cognition and mental abilities. Most of the topics introduced in this book cover new techniques in the diagnosis and management of neurodegenerative disorders. Different approaches, evaluations, methodologies and advanced studies on this medical condition have been included in it. This book will provide comprehensive knowledge to the readers.
