one MCI participants (32 carriers and 49 non-carriers) were assessed on a standard neuropsychological battery. Between groups comparisons were made for two episodic memory tests and two executive functioning tests. Results: No significant differences were found in the cognitive measures when comparing carriers vs non-carriers in the AD group. In the MCI group carriers displayed greater impairment onmeasures of verbal (P1⁄4 0.007) and nonverbal memory (P 1⁄4 0.011), whereas non-carriers were more impaired on letter fluency executive ability (P 1⁄4 0.003). Conclusions: The results of the current study indicate a cognitive dissociation between carriers and noncarriers in theMCI but not the AD group. This appears to be the first study to identify this dissociation in a population not yet clinically diagnosed with AD dementia. One explanation for this finding is that individuals diagnosed with MCI who do not go on the develop AD are overrepresented in the noncarrier group. Furthermore, the study not only fails to replicate the recent findings of cognitive dissociation in the AD group, but it does not indicate a difference between carriers and non-carriers on memory measures in this group.
