【摘要】:目的:探討6~18歲高功能孤獨癥患者的灰質(zhì)體積異常腦區(qū)以及異常腦區(qū)發(fā)育特點。方法:納入19例6~18歲符合美國精神障礙診斷與統(tǒng)計手冊第4版孤獨癥診斷標準且總智商≥70的高功能孤獨癥患者,以及年齡、總智商、性別組間匹配的16例正常對照,以磁共振成像檢查收集被試的腦影像學資料,采用基于體素的形態(tài)學測量方法計算兩組被試大腦各區(qū)域的灰質(zhì)體積,在統(tǒng)計學參數(shù)圖(SPM)軟件SPM8中進行雙樣本t檢驗得出差異腦區(qū),對結(jié)果進行錯誤率(FDR)多重比較校正(P0.05)。采用偏相關(guān)分析兩組被試差異腦區(qū)灰質(zhì)體積與年齡的相關(guān)性。結(jié)果:高功能孤獨癥組的右側(cè)額下回眶額部灰質(zhì)體積小于正常對照組(FDR校正,P0.05)。正常對照組右側(cè)額下回眶額部灰質(zhì)體積與年齡呈負相關(guān)(r=-0.592,P0.05),高功能孤獨癥患者右側(cè)額下回眶額部灰質(zhì)體積與年齡呈負相關(guān)(r=-0.696,P0.01)。結(jié)論:與正常人相比,6~18歲高功能孤獨癥患者右側(cè)額下回眶額部發(fā)育異常,此腦區(qū)可能參與孤獨癥的病理機制。
