What causes Alzheimer's Disease?

Scientists are still not certain. Research suggests that the central problem in Alzheimer's disease is malfunction and death of nerve cells, but scientists are still working to learn why this happens. Key areas of ongoing study focus on biochemical processes and pathways in nerve cells, effects of inflammation, and the influence of genes. Many experts believe that Alzheimer's usually arises from a complex combination of factors. Future treatements may involve a variety of approaches aimed at prevention, improving or delaying symptoms, or modifying cellular chemistry.
