It is a nonspecific finding and is associated with multiple neurological syndromes, including agenesis of the corpus callosum, Chiari malformation, lissencephaly, and microcephaly. Although the exact cause of colpocephaly is not known yet, it is commonly believed to occur as a result of neuronal migration disorders during early brain development, intrauterine disturbances, perinatal injuries, and other central nervous system disorders. Individuals with colpocephaly have various degrees of motor disabilities, visual defects, spasticity, and moderate to severe intellectual disability. No specific treatment for colpocephaly exists, but patients may undergo certain treatments to improve their motor function or intellectual disability. == History == These brain abnormalities were first described by Benda in 1940 as 'vesiculocephaly'. In 1946, Yakovlev and Wadsworth coined the term colpocephaly from the Greek work ''kolpos'' (hollow) and ''kephalos'' (head). It was suggested that the enlargement of ventricles occurred as a result of white matter development arrest during early fetal life.〔 They stated that “in the apparent dilatation of the occipital horns...it represented a failure of development of the cerebral wall with persistence of the embryonal vesicular character of the brain." Yakovlev meant for this term to apply to the end result of disturbances during the development of the brain. He suggested the term 'hydrocephalus ex vauco' to be used for enlargement of the occipital horns of the lateral ventricles as a result of damage to the brain after it is normally formed. However, today the term colpocephaly is used to describe both the situations.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Colpocephaly」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
