Huntington's disease is a genetically inherited condition which results in severe nerve-cell damage in the brain. The hereditary and debilitative nature of the disease means that many people are involved either directly or indirectly by this condition. This book has been written for patients and the families and carers of people with Huntington's disease (HD). It provides an accessible introduction to the condition that explains the physical, behavioural, and emotional features of the disease, the important role of genetics and options for those at risk of developing the condition, plus advice on managing and treating symptoms. Patient perspectives are included throughout, offering real-life accounts from people who have or know someone with the condition.This new edition has been fully updated to include all the latest research in HD. It gives more detail on the standard treatments, as well as explaining new trials aimed at reducing the level of the abnormal protein (huntingtin) in the brains of patients.
