Neuropsychological assessment of monolingual Spanish-speaking people in the United States is both a common practice and an ethical dilemma. Lack of appropriate tests, the absence of norms, use of interpreters, and the multiplicity of in-house translations of commonly used measures add to the problem of accurate assessment. This paper helps address the lack(More)

These patients were compared with 30 with a research diagnosis of Alzheimer's disease (AD). We scored every patient on each LMRC item and compared the two groups. A discriminant function showed that(More)

It also addresses the practice of neuropsychology with Hispanics in the United States and posits that it should take into account the heterogeneity of this population (the largest minority group in the country).(More)
Development of improved outcome measures for Alzheimer's disease (AD) clinical trials is a major objective of the Alzheimer's Disease Cooperative Study (ADCS), an NIA-sponsored, multisite clinical trials consortium. The ADCS is committed to recruiting and following minority patients in clinical trials. At present, a serious impediment to recruiting(More)
