Issues affecting minority participation in research studies of Alzheimer disease.

Despite the need for minority subjects in research studies of Alzheimer disease (AD), the successful involvement of minority patients in such studies has been difficult. This report discusses the many societal, economic, logistical, and attitudinal barriers that have inhibited the participation of minority patients and their families in medical research programs of AD. Special consideration is given to the unique cultural issues that arise when conducting studies involving African-American elderly subjects. Methods are considered for overcoming the barriers to participation gleaned from the national study CERAD (Consortium to Establish a Registry of Alzheimer Disease) and other investigations of AD. Recommendations are made for future research programs targeted on the specific health care needs and concerns of the minority segments of our population.
