基于靜息態(tài)低頻振幅探討針刺神庭、百會對腦小血管病認知功能障礙的中樞機制摘要:本文針對腦小血管病認知功能障礙,探討了針刺神庭、百會對其中樞機制的影響。采用靜息態(tài)低頻振幅測試方法,結合腦磁圖掃描技術和行為學表現(xiàn),研究了60例患者在針刺前后的腦功能狀態(tài)變化情況,并與健康對照組進行比較。結果表明,針刺神庭、百會能顯著提高腦區(qū)間相干性、增加腦部灰質(zhì)體積,改善患者認知功能狀態(tài)。其中,神庭主要影響前額葉-顳葉區(qū)域,百會主要影響顳葉-頂葉區(qū)域。此外,與其他針刺點相比,神庭、百會對腦小血管病認知功能障礙的中樞機制影響最為顯著,可能與其改善血液循環(huán)、抗炎抗氧化等作用有關。
