Alzheimer's disease is a progressive neurodegenerative disorder that leads to severe cognitive decline and memory loss. Research on Alzheimer's risk focuses on identifying factors that increase the likelihood of developing the disease, such as genetics, age, lifestyle habits, and medical history. By understanding these risk factors, researchers aim to improve early detection, prevention, and treatment of Alzheimer's disease. This research area plays a crucial role in improving our understanding of the disease and developing effective strategies to combat it.
