Neurology is a specialized branch of medicine that focuses on the study, diagnosis and treatment of disorders and diseases affecting the nervous system. The nervous system is a complex network of cells, tissues and organs that coordinate and control the functions of the body. It consists of the central nervous system, which is made up of the brain and spinal cord, and the peripheral nervous system, which comprises nerves and ganglia outside the brain and spinal cord. A few of the neurological conditions which are diagnosed and treated within this field include stroke, epilepsy, multiple sclerosis, Parkinson's disease, Alzheimer's disease, migraine and neuropathies. This book explores all the important aspects of neurology in the present day scenario. It will serve as a valuable source of reference for graduate and postgraduate students.
