目的：虛談現象（confabulation）為前交通動脈（Aneterior Communicating Artery, ACoA）動脈瘤破裂後常出現的症狀之一。然而，過去研究對該現象卻未見深入之討論。因此，本研究報告一位ACoA動脈瘤破裂後出現虛談現象之患者，藉由神經心理衡鑑，探討相關之機制與腦部損傷位置之關係。
方法：本研究報告一位四十二歲、慣用右手的男性患者。在ACoA動脈瘤破裂後二個半月，評估其虛談現象與其他神經心理功能。
結果：本研究結果顯示，患者有明顯的虛談現象。神經心理衡鑑結果亦指出，患者在定向感、記憶功能、執行功能與精細動作上亦有明顯缺損。
結論：患者之執行功能缺損為虛談現象的可能成因；然而，記憶功能中的輸入與提取功能皆發現異常，顯示記憶功能缺損，亦有可能影響虛談現象的形成。

Objective: Confabulation is not uncommon after a ruptured aneurysm of the anterior communicating artery (ACoA). In fact, patients with confabulation usually have remarkable difficulties in their daily livings. Unfortunately, the past studies which explored the confabulation were limited in number. This study thus aims to examine neuropsychological functions of a patient with a ruptured aneurysm of the ACoA, and to further reveal its possible underlying mechanism.
Methods: A 42-year-old, right-handed male was evaluated by a comprehensive neurological, neuropsychological and neuroradiological assessment at 2 and half months after the ruptured aneurysm of the ACoA.
Results: A remarkable confabulation was observed. Moreover, patient had significant difficulties in orientation, memory, executive function and sensory-motor abilities.
Conclusion: This study might be the first one to present the confabulation and comprehensive neuropsychological features after a ruptured aneurysm of the ACoA in Taiwan. Even though the executive dysfunction might cause the confabulation, the contribution of patient’s memory deficits could not be ignored.
