孤独症生命早期脑过度生长现象及启示

Brain Overgrowth in Austin During the Early Life and Its Implication

孤独症神经结构研究中近来一个重要的发现是，孤独症生命早期存在脑过程生长的现象。进一歩的探查表明，孤独症个体脑的过程生长主要由脑白质的过度生长造成，并且脑的过度生长又主要体现于那些较晚成熟的高级脑区。这一研究成果有助于孤孤症儿童的早期发现和诊断，也提示孤独症并不是由单一的局部神经缺陷造成，其存在着广泛分布式的神经发展障碍。

In the study of brain structure of autism， an important conclusion has recently been drawn that the brain of autism overgrows in their early life compared with normal individual. Further， it has been revealed that the brain overgrowth is primarily due to the abnormality in white matter. Moreover， it has been found that the overgrowth is more obvious in the later developmenting cerebral areas mediating higher─order functions. As a result， the finding can be applied to the early identification of autism. In addition， it also can be duduced that autism is not attributed to localized neurological abnormalities. Actually， there may be a distributed neurological disorder in autism.
