Alzheimer's Disease is a progressive neurological disorder that primarily affects older adults, leading to memory loss, cognitive decline, and behavioral changes. It is the most common cause of dementia, gradually impairing a person's ability to carry out daily tasks. Alzheimer's is characterized by the accumulation of abnormal protein deposits in the brain, which disrupts communication between neurons and ultimately leads to their death. Early symptoms include forgetting recent events or conversations, confusion about time or place, and challenges in problem-solving. As the disease advances, individuals may experience language problems, mood swings, and difficulty recognizing loved ones. Currently, there is no cure for Alzheimer's Disease, and treatments focus on managing symptoms and improving quality of life. Research into its causes and potential therapies continues, aiming to understand and mitigate its devastating impact on individuals, families, and society. This book attempts to understand the multiple factors that contribute to the development of Alzheimer's Disease. It discusses the fundamentals as well as modern approaches of treatment of neurodegenerative disorders. This book is a vital tool for all researching or studying such disorders as it gives incredible insights into emerging trends and concepts.
