Priorities for research consortia on Alzheimer's disease.

Coordination and harmonization of efforts between five major research consortia on Alzheimer's disease may increase our understanding of this condition and improve our therapeutic approaches. Specific opportunities include a registry for families with early onset dementia, a study registry, minimal data sets, validation of assessment tools and outcomes, update on ethical issues, resolution of methodological issues, new investigators training, longitudinal observation studies, prevention studies, and liaison with stakeholders such as Alzheimer Disease International.
