Dementia diagnosis is evolving rapidly, yet one critical dimension remains overlooked: the powerful ways that sex/gender, mental health, and psychosocial context shape cognitive performance-and therefore, diagnostic accuracy.Fear of Forgetfulnessoffers the first comprehensive, clinically grounded exploration of these influences, illuminating how they complicate early detection and often obscure the prodromal signs of disease. Bridging cutting-edge research with decades of clinical practice, this book reveals how anxiety, depression, functional cognitive disorders, and even biomarker procedures themselves can alter cognition, behavior, and patient experience. Through clear explanations and real-world examples, it exposes why misdiagnosis or misdirected management is so common, particularly in individuals whose symptoms arise from non - neurodegenerative causes. Designed for clinicians, trainees, and anyone navigating concerns about memory loss, this guide provides practical approaches to identifying and mitigating diagnostic confounds-enhancing clarity, improving patient care, and reducing unnecessary fear. Grounded in applied neuroscience and preventive brain health, it equips readers to recognize what truly signals dementia and what does not, empowering more accurate diagnosis and more effective support at every stage.
