Benefit of phonemic cueing on confrontation naming in Alzheimer's disease

Individuals with probable AD who benefit more from phonemic cueing during confrontation naming tend to have higher estimated premorbid IQ and are milder in dementia severity. There is a positive association between phonemic cueing benefit and performance on select semantic measures and verbal fluency. Differences in phonemic cueing benefit between carriers and noncarriers of APOE ε4 allele can be explained by spontaneous naming performance. Results suggest complexity of underlying mechanisms involving confrontation naming, phonemic cueing, and lexical access and the factors that influence them.
