Optimizing Detection of Very Mild Aphasia With Letter Fluency Tests

The combined letter fluency and two-letter fluency tests were sensitive in detecting very mild aphasia beyond what is captured in the WAB-R. Administration takes an estimated 11 min, making it accessible to clinicians in various settings. While letter fluency tests rely on phonological and orthographic knowledge, they are also frequently used to measure executive control. Thus, this combined letter fluency test should be used in conjunction with other language and cognitive assessments to determine treatment targets.
