康復干預可出現(xiàn)中樞性吞咽功能障礙時神經(jīng)功能中樞代償性重組現(xiàn)象

1、康復干預可出現(xiàn)中樞性吞咽功能障礙時神經(jīng)功能中樞代償性重組現(xiàn)象目前，對于大腦吞咽功能中樞損傷后的可塑性機制仍然不是很清楚。來自中國河北聯(lián)合大學的元小冬教授所在研究團隊，應用血氧水平依賴腦功能性成像技術(shù)觀察了腦梗死導致的中樞性吞咽功能障礙患者在給予吞咽活動刺激任務(wù)時，激活腦相關(guān)皮質(zhì)中樞區(qū)域的功能影像學特征，發(fā)現(xiàn)中樞性吞咽障礙患者前扣帶回等吞咽活動啟動中樞的激活明顯減弱，而且急性腦病變同側(cè)吞咽活動相關(guān)中樞的激活強度也明顯降低，但急性腦病變對側(cè)吞咽相關(guān)中樞的激活強度無明顯變化，同時出現(xiàn)后扣帶回、前額葉、視、聽皮質(zhì)及小腦等中樞區(qū)域激活明顯增強的現(xiàn)象，說明中樞性吞咽功能障礙患者出現(xiàn)了神經(jīng)功能中樞代償性重組

2、現(xiàn)象。這提示在進行康復治療時，可以給予患者以往喜歡的食物通過視覺和聽覺等神經(jīng)傳導途徑對其吞咽活動相關(guān)進行刺激，從而促進皮質(zhì)中樞功能的代償性重組，從而提高康復治療效果。相關(guān)文獻發(fā)表于中國神經(jīng)再生研究（英文版）雜志2015年3月第3期。右側(cè)腦梗死導致的中樞性吞咽功能障礙患者在給予吞咽活動刺激任務(wù)時其右側(cè)BA4區(qū)被激活，但是激活體積小于正常志愿者Article: " Compensatory recombination phenomena of neurological functions in central dysphagia patients," by Xiao-dong

They found that when recu

7、rrent cerebral infarction patients with central dysphagia swallowed, the degree of activation in the anterior cingulate cortex was decreased, but the activation intensity on the unaffected side was not obviously changed. Additionally, more areas were activated, including posterior cingulate cortex,

8、visual association cortex, primary auditory cortex, parahippocampal cortex, somatosensory association cortex and the left cerebellum. These findings suggest that patients with recurrent cerebral infarction with central dysphagia show compensatory recombination phenomena of neurological functions. Th

9、us, in rehabilitative treatment, using patients favorite food to stimulate the swallowing function through visual, auditory, and other nerve conduction pathways can promote the compensatory recombination of the central cortex functions. When performing swallowing, the right BA4 region was activated,
