Rapcsak Sensitivity of Different Language Measures Lead Investigator: Laura Wojtulewicz Institution : Arizona State University E-Mail : whitz@asu.edu Proposal ID : 419 Proposal Description: I was wondering about the sensitivity of different language measures (BNT, animal/vegetable fluency, COWA/letter fluency) for identifying problems at different stages of the disease. For instance, if we look at normal controls, do people with genetic risk (APOE4 homo/hetero) already perform worse on any of these measures than non-carriers? How common is language impairment in MCI vs. AD and what is the typical pattern of progression?
