On Which Abilities Are Category Fluency and Letter Fluency Grounded? A Confirmatory Factor Analysis of 53 Alzheimers Dementia Patients

摘要

Background/AimsIn Alzheimer's dementia (AD), letter fluency is less impaired than category fluency. To check whether category fluency and letter fluency depend differently on semantics and attention, 53 mild AD patients were given animal and letter fluency tasks, two semantic tests (the Verbal Semantic Questionnaire and the BORB Association Match test), and two attentional tests (the Stroop Colour-Word Interference test and the Digit Cancellation test).
