<p> Early detection of Alzheimer&rsquo;s disease (AD) is crucial. The risk of progressing to advanced stages is higher among those in the earliest stages of AD, and early diagnosis can lead to more effective treatment. Language assessments can be effective in diagnosing AD early. The current study evaluated the effectiveness of action fluency tasks in detecting early AD. An individual with early AD and a normal aging individual participated in three verbal fluency tasks: letter, category, and action. Results revealed that the individual with early AD performed more poorly than the normal aging individual on most verbal fluency tasks, including action fluency. Comparison of these results to performance on a discourse production task revealed a correlation between the category and action fluency tasks and the discourse production task but no correlation with the letter fluency task. The findings add support to the effectiveness of action fluency tasks in detecting early AD.</p><p>
