Alzheimer's research is equal measure hope and frustration. Cord blood might be a much-needed solution.
Few diseases stump researchers as much as Alzheimer's disease. Quite simply, nothing has worked beyond some symptomatic relief. On top of that, scientists are still uncertain about what exactly causes the disease. For example, are the characteristic beta-amyloid plaques in the brain a cause of Alzheimer's disease -- or a consequence? Any promising results are welcome to a community used to setbacks.
