中文摘要 | 傳統上認為,小洞梗塞症候群的臨床表徵中、不應該有高級大腦皮質功能的障礙。 但文獻中卻有報告在某些特殊、重要部位的小洞梗塞,可以導致高級大腦皮質功能障礙,位 在內囊膝部及視丘的小洞梗塞就是一個例子。 我們報告四位患者,因小洞梗塞雨造成記憶與智能喪失;這些病人中有兩位是左側視丘 梗塞、一位是左側內囊膝部梗塞、一位是右側內囊膝部梗塞。其中一位病患的記憶與智能喪 失是短暫性的,四個月後所作的神經心理學測驗顯示這些高級大腦皮質功能已經回復正常; 其他三位則有嚴重、且持續的智能喪失。 視丘梗塞的患者是由於侵犯視丘的背內側核及腹外側核而造成記憶與語言障礙;可能是 因為直接侵犯「核」,所以其高級大腦皮質功能障礙比較持績。而內囊膝部附近梗塞造成的 高級大腦皮質功能障礙是由於視丘皮質連接神經束,在內囊膝部遭阻斷所致,而其確實機轉 不明。再者,文獻報告中.有些病人可完全恢復,有些卻有嚴重後遺症及生活障礙,造成這 種差異原因也是不明的。 |
英文摘要 | Impairment of higher cortical functions is usually not considered as a typical presentation of lacunar infarction. However, a small discrete lesion at strategically important locations may produce memory loss and mental changes. We report 4 patients with lacunar infarctions manifested as acute amnesia and mental changes. One patient had left thalamic infarction, one had left capsular genu infarction, one had right capsular genu infarction, and one had left capsular genu infarction extending to the ipsilateral thalamus. The mental and memory impairment was transient in one patient but was persistent in the other 3 patients. Our report reconfirms that a lacunar infarction can cause impairment of higher cortical functions. |
