造成忽略的原因可能為出血性或缺血性的腦中風、腫瘤或外傷，甚至退化性的腦病變也有可能造成忽略症候群。

急性腦部受損患者的研究發現，右大腦半球的受損（43%）較左大腦半球受損（20%）較常發生忽略的現象。

而若以受傷區域對應其臨床症狀，前葉(frontallobe)受損患者很難將其注意力從傷側移開(通常是右側)；頂葉(parietallobe)與基底核(basalganglia)受損者其視覺定向及掃視的控制可能會有障礙；視丘(thalamus)主要匯整嗅覺以外之感官的輸出與主掌選擇性注意，除此之外，視丘與清醒度的調節也有很大關係，因此視丘受損易造成對側忽略，患者會很難注意到傷側對側物體。

其他相關研究也顯示，相較於完全性失語症患者和右側偏盲患者，忽略症患者的獨立生活能力較差，故忽略對於患者之影響不容小覷。

   忽略的症狀包括知覺無法注意(sensoryinattention)、動作無法注意(action-inattention)與空間忽略(spatialneglect)。

臨床上視覺之無法注意(inattention)與偏盲(hemianopia)常會造成混淆，區辨方式如下：視覺上的無法注意是轉動眼球就可看到，但偏盲是無論眼球如何轉動都無法看到傷側對側物體。

若一名患者傷及右腦，他可能看不到左側物體，但施測者若請患者將眼珠轉向右側即可看到左側物體，則此患者可能為視覺忽略而非單側偏盲。

知覺無法注意(sensoryinattention)可能出現無意識現象(unawareness)與消失現象(extinction)。

無意識(unawareness)是一種同側注意力的偏差，若一名患者傷及右腦，他將無法將注意力從右側移開。

而有消失(extinction)現象的患者（假設也傷及右腦）看到一堆樣式各異的物體時，他只會注意到在右側的物體，但如果給予的物體是有類聚(grouping)效果的，例如相同形狀，顏色等，讓患者認為這是『一個物體』，患者才會較注意到靠近左側的物體，可以利用此原則來消弱忽略患者的消失現象。

動作無法注意(action-inattention)也稱作動作忽略(motorneglect)，臨床症狀類似於偏癱，但偏癱患者會嘗試動他的無力側，動作忽略患者則無移動其傷側對側肢體的跡象。

動作忽略分為以下形式：（以下以右大腦半球受損的忽略患者說明之）1. 半側空間動作失能(hemispatialakinesia)：患者無法移動在傷側對側的肢體。

例如若把一名右腦受損患者肢體放在左邊會沒有動作，但把肢體移到右邊就可動作。

2. 方向性動作失能(directionalakinesia)：動作失能的現象與肢體所在方位有極大關係。

有些患者無法將頭、眼甚至上肢移動至左側，但有些患者的頭、眼或上肢左右兩側皆可移動，但休息時會傾向於右側。

視覺的方向性動作失能常發生於大面積中風患者，此時就可能被誤解為gazepalsy。

3. 動作減少(hypokinesia)：患者會有起始動作延遲的現象。

有可能同時發生於眼睛與肢體，也可能會受到方向的影響，右腦受損患者將物體移至左側的延遲現象比移向右側來的嚴重。

4. 動作不能持續(motorimpersistence)：無法維持動作或姿勢。

測試方式為請患者閉眼20秒或是維持張口20秒，若其中一項可執行則請患者同時閉眼與張口維持20秒。

也可請患者維持上肢伸直20秒，傷側對側肢體幾乎很難維持伸直姿勢。

5. 辨距低估(hypometria)：動作的幅度減少。

一名右腦受損患者剛開始可能無法轉向左側或是移動左側肢體，但隨著狀況的改善，患者可能慢慢的可移動左側肢體但起始動作緩慢，或是可動左側肢體但辨距低估只有小幅度的動作。

6. 動作消除(motorextinction)：右腦受損患者可以單獨動左
