Abstract
This book provides a clear and readable introduction to the central concepts of clinical neuroscience. The first part of the book deals with fundamental areas of neuroscience required for a sound understanding of brain disease. This is followed by an account of the neurobiology of the most common and important brain diseases of the western world (stroke, epilepsy, Alzheimer's disease, Parkinson's disease and multiple sclerosis). The book is in the same general style as the successful Crossman: Neuronatomy with extensive colour illustrations.
Short, affordable and readable introductory level text in the smae style as Crossman: Neuroanatomy.
Assumes little previous neuroscience knowledge.
Explains fundamental concepts without overwhelming detail
Focuses on clinically relevant material.
Includes the most common and important neurological disorders.
