聾啞者失語症：病例報告

先天聾者因聽覺障礙，多不具有口語溝通能力，一般僅能使用手語及文字溝通，是爲聾啞者。正因聾啞者不具有口語溝通能力，其是否失去語言能力，在診察中就容易被忽略。在此提供一位45歲，先天聾啞，慣用右手之男性病例，之前以手語及文字與人溝通，因罹患左側額顳葉惡性腦瘤致失去包括手語及文字的所有溝通能力。患者在第一次術後6月，手語及文字溝通能力皆有部份恢復，其中文字溝通能力之恢復較手語早且好，兩者均以理解力恢復較佳。不幸腦瘤快速復發，令患者的溝通能力無法持續進步。雖然語言的輸入與輸出模式與一般聽力正常的人不同，但聾啞者與一般人腦部對語言功能之特別化是一致的。一旦優勢大腦遭遇病變，便和一般聽力正常的人相同，一樣會有失去語言理解及表達能力的失語症發生。回顧過去國外之病例報告及文獻，聾啞者的失語症亦隨其病兆不同而有不同之影響及復原情況。

Congenitally deaf persons don't have the ability to communicate verbally due to profound hearing impairment. Thus, they rely on words and sign language to communicate with others. Physicians tend to pay less attention to people who can't communicate verbally. We report the case of a 45-year-old congenitally deaf man who developed a left frontotemporal brain tumor. He was right-handed. As a result of the tumor, he lost both the ability to form words and the sign language he had relied upon to communicate with others. He recovered some ability to communicate 6 months after surgery. He was able to use words to communicate better than with sign language. He was able to receive information better than to express it by words or sign language. Unfortunately, recurrence of the tumor halted his improvement. Despite radically different input/output modes, deaf persons have the same common patterns of cerebral specialization for language functions as do persons with normal hearing. Aphasia in congenitally deaf persons is analogous to that in persons with normal hearing, and loss of language reception and expression results from pathology in the dominant hemisphere. The effects and the improvement in aphasia in a deaf person depend on the individual lesion.
