Introduction: Metaphor, thanks to its statue, as one of the most widely used language variety, and due to its abstract meaning, is an appropriate field of research in patients suffering from cognitive deficits. Purpose: This research aims at investigating dead and novel metaphor comprehension in Persian-Speaking Alzheimer’s patients, and analyzing the role of executive function in this process. Method: This research is a co-relational one. The statistical society is composed of 5 Persian-speaking Alzheimer’s patients and their age-education matched healthy controls. To assess patients’ executive abilities and metaphor comprehension, stroop color, clock drawing and metaphor comprehension tests were used respectively. Results: The results showed Alzheimer’s patients’ deficit in metaphor comprehension, particularly in novel ones. Patients’ performance in metaphor comprehension was related with theirs in stroop color test and clock drawing tests, though this correlation was more significant in the case of novel metaphors. Conclusion: On one hand, the relationship between patients’ metaphor comprehension and their executive abilities demonstrate that deficit in executive system plays an important role in patients’ poor metaphor comprehension, and on the other hand, this highlights the significant role of pre-frontal cortex in metaphor comprehension.
