(aquaporin-4, AQP4) 抗体が同定され，MS から NMOSD が分離独立した．現在，MS は髄鞘 (標的抗原未同定) を標的とするオリゴデンドロサイトパチー，NMOSD はアストロサイトに発現する水チャネル AQP4 を標的とするアストロサイトパチーと考えられている．本研究では，MS と NMOSD の認知機能障害と脳萎縮の縦断的解析を行った．対象は，MS 24 例，NMOSD 16 例，少なくとも 3 年以上の間隔をあけ評価可能な症例とした．認知機能評価は，Rao らの神経心理学的簡易反復検査法 (brief repeatable battery of neuropsychological test, BRBN) を実施した．神経放射線学的評価は，voxel based morphology (VBM) による脳体積の計測を実施した．NMOSD と比較してMS では，第一に認知機能障害は縦断的に悪化すること，第二に縦断的に大脳全体，特に帯状回と後頭葉 (中・下後頭回，舌状回，紡錘状回) が萎縮すること，第三に認知機能障害と大脳 (帯状回と後頭葉) の体積萎縮に相関関係があること，第四に MRI・DIR 法で見いだされる皮質脱髄病変を認めることを見出した．さらに，この期間では，皮質脱髄病変の新たな加算を認めなかった．異なるグリア細胞を標的とする自己免疫性グリア病であるMSとNMOSDは，脳萎縮と認知機能障害の進行様式が異なることが示唆された．", "subitem_description_type": "Abstract"}]}, "item_6_description_53":
