This book proposes specific lifestyle interventions to improve health, slow aging, and reduce the risk of late-onset Alzheimer’s disease (AD). This book is not intended to provide steps to address other types of dementia, such as frontotemporal dementia, Lewy body dementia, spongiform disorders, and so on. You should consult a qualified medical professional before initiating these interventions or any other fitness regimen. The interventions in this book are intended to be implemented in consultation with your doctor, and this is especially so if you suffer from any medical condition.
