Strategies for increasing participation of ethnic minorities in Alzheimer's Disease Diagnostic Centers: a multifaceted approach in California.

A unified, state-wide effort to increase outreach activities targeted to ethnic minority families with a demented relative is described. A variety of strategies are reported, along with data supporting the effectiveness of these outreach efforts. At present, it appears that the three major ethnic minority groups in the State of California (i.e., Hispanic, African American, and Asian) are utilizing the network of state diagnostic centers at a rate proportional to their representation in the population.
