The concept of advocacy literally means to speak for someone. Rooted in law, the term has been increasingly used in medical and patient-related contexts in the past years. This book focuses on advocacy activities in the field of neurology. Neurology deals with heterogeneous and diverse populations of patients, who suffer from disability, chronic, and often progressive diseases. The complex characteristics of neurological diseases yield exceptional challenges to plan for and implement advocacy activities on all levels. All stakeholders are challenged to provide the support patients need; advocacy facilitates this process and bundles efforts to reach the objective of the advocacy task. Building on the premise that advocacy goes beyond merely theoretical claims, this book collects and organizes advocacy approaches in practice. Thereby, we draw on different dimensions of ‘advocacy in neurological practice’ and discuss implications for management, healthcare, planning, and policymaking. We place special emphasis on what advocacy means for several different diseases, such as amyotrophic lateral sclerosis (ALS), brain tumours, MS, epilepsy among others. Contributions include best practices, lessons learnt, and tools to be used. The main goal of this book is to raise awareness for advocacy in neurology and empower readers to plan for and implement appropriate activities. In advocacy, anyone can be both an advocate and an advocatee. This book offers a seminal contribution for anyone who is pursuing or intending to pursue advocacy in neurology and related fields.
