Abstract

 児童虐待は, 日本の少子化社会の中でも近年増加の一途をたどっている. 小児期に様々な虐待経験のある被虐待者脳MRI形態の検討により, 虐待や育児放棄による幼少期母子関係の破綻 (愛着形成の障害) が社会性の発達障害を引き起こすこと, さらにその障害が脳の構造機能の変容に起因することが示唆された. 「性的虐待」では, 最初に目に映った情報を処理する脳の視覚野で脳の容積が減ったり, 「暴言虐待」では, コミュニケーション能力に重要な役割を持つ聴覚野で大脳白質髄鞘化が異常をきたしたりすることが明らかになった. 被虐待児に認められる “社会性発達障害” という観点から, こころに負った傷は容易には癒やされないことが予想される. 被虐待児たちの精神発達を慎重に見守ることの重要性を強調したい. しかしながら, 被虐待児たちの脳変成も多様な治療で改善される可能性があると考えられる.

  In recent years, the topic of child abuse as an issue facing Japanese society has gained considerable attention with regard to the field of medicine and education and also in scenarios that relate to child care. The definition of child abuse includes abusing children verbally or psychologically, and is not limited to abusing children physically such as beating, sexual abuse, or neglect. Recent studies have revealed that emotional trauma during childhood development could be much more difficult to treat than physical abuse. Severe abuse during childhood can cause abnormal brain development and have a negative impact later in life. In this review, I will introduce the mechanisms of brain damage due to child abuse with consideration of how and when child abuse can have an impact on the victims' brains. The information presented is based on a collaborative study with the Psychiatry Department at Harvard University on the relationship between brain functions and the human mind.
