Fukushima students having their brain atrophied

 

About 20% of the 42 students in Tohoku university, who had MRI before 311 turned out to have their left orbitofrontal cortex become atrophied from MRI test to follow after 311.
They also suffer from PTSD.

Those 42 students consist of 33 male, 9 female and the average age is 21.7.

Prof Kawashima from Institute of Development, Aging and Cancer, Tohoku University compared the MRI result taken in June ~ July of 2011 to the one taken before 311.

The left orbitofrontal cortex is to remove memories to provoke fear or anxiety. Researcher Sekiguchi from the same group as Kawashima comments, the atrophied left orbitofrontal cortex could not process fear properly.
Also, the students who had smaller part of the brain except for left orbitofrontal cortex suffer from PTSD more severely.

 
東日本大震災:PTSD症状訴える学生 脳の一部分が萎縮

東日本大震災で心的外傷後ストレス障害(PTSD)のような症状を訴える学生の脳の一部分が、震災前と比べて萎縮していたことを、東北大加齢医学研究所の川島隆太教授らのグループが、脳の画像診断の比較で突き止めた。また、脳の別部分の体積が震災前に小さかった学生ほど、症状を訴えやすいことも判明した。川島教授によると、画像診断でPTSDの診断ができる可能性を示したのは初めて。

震災前、磁気共鳴画像化装置(MRI)で脳の画像を撮影していた東北大生42人(男性33人、女性9人、平均21.7歳)について、11年6〜7月に再撮影した。

ボランティアや震災情報に接することの多い仙台での生活で不眠やフラッシュバックなどPTSD様の症状があった約2割の学生に、恐怖や不安などを伴う記憶を消去する機能がある左眼窩前頭皮質が震災前より減少している傾向が確認された。同グループの関口敦研究員は「体積が小さくなったことで恐怖を処理しきれなくなっている可能性が高い」としている。

研究結果は米精神医学誌電子版に掲載された。【竹田直人】

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
