中文摘要

文獻中指出,看似不嚴重且恢復期短的輕度頭部外傷個案仍存有隱而微現的 認知損傷,認知損傷後遺症會影響個案日常生活、工作與社會功能,而抑制控制 是認知控制的關鍵成分。本研究目標乃是探討輕度頭部外傷個案傷後三個月後抑 制控制能力的缺失,共招募12 對輕度頭部外傷個案與正常健康成人參加抑制相關 的神經心理測驗(綜合路徑描繪測驗、電腦化持續性注意力測驗、威斯康辛卡片 分類)和修改過停止信號任務,比較兩組的差異。在神經心理測驗中,顯示輕度 頭部外傷個案有注意力及衝動的問題。在停止信號任務的停止試驗中,輕度頭部 外傷個案抑制機率低於控制組,停止信號反應時間比控制組長,本研究顯示因頭 部震盪損傷導致輕度頭部外傷個案在動作抑制控制能力較差,即便是傷後三個月, 仍可觀察到其抑制控制能力的缺損。

英文摘要

Previous studies have indicated that subtle deficits in cognitive function may persist beyond the acute stage of injury in mild traumatic brain injuries (MTBI) despite the rapid restoration of functional performance. Cognitive sequelae threaten an individual’s ability to engage successfully in activities of daily living, work, and social function. Inhibitory control is a key component of cognitive control. The goal of the present study was to investigate the inhibitory control in MTBI beyond 3 months post-injury. Both 12 MTBI and 12 healthy controls were administered neuropsychological assessments (Comprehensive Trail Making Test, Continuous Performance Task, and Wisconsin Card Sorting Test) and a modified Stop-signal Task respectively. MTBI displayed attention impairment and impulsiveness on neuropsychological assessments. Additionally, deficits in the inhibition of ongoing response were exhibited in MTBI while performing Stop-signal Task; lower inhibition ratio and longer stop-signal reaction time were shown. Our findings suggest that deficits in inhibitory control may persist beyond the initial three-month recovery phase in MTBI.
