It is almost 120 years since Alzheimer’s disease (AD) was first reported, and the concept of managing some of the modifiable risk factors associated with the disease has been present from the outset. Intervening to manage risk factors as a way of tackling AD is not new, but optimizing brain health as a way of minimizing risk and maximizing the potential benefits of revolutionary new treatments for AD is becoming increasingly important. This book, the Handbook of Intervention and Alzheimer’s Disease, presents 47 papers exploring factors which may either inspire or inform future treatment and clinical trials. While novel interventions such as anti-amyloid immunotherapy present great opportunities, they may also increase the risk of brain bleeds and edema, which in turn may lead to adverse clinical outcomes. Such adverse outcomes are demonstrably more likely to occur in persons with poor brain health, so improved management of the risk factors which make up the AD preventome will also minimize the risks associated with such novel therapies. The papers in this volume can therefore be thought of as offering insight into those factors that can optimize brain health or providing key insights into interventions which may achieve such outcomes. Together with its companion volume on prevention, the book provides a comprehensive overview of strategies for tackling Alzheimer’s disease, and will be of interest to all those working in the field.
