A new research shows that worrying is good for the brain and is vital for human survival, the Daily Telegraph reported.

A study of 42 people found the worst sufferers of a common anxiety disorder to have a higher IQ than those whose symptoms were less severe.

The findings were published in the journal Frontiers in Evolutionary Neuroscience.

Psychiatrist Professor Jeremy Coplan of SUNY Downstate Medical Centre, said: "In essence, worries may make people take no chances and such people in turn then may have higher survival rates." （点击《每日电讯报》查看原文）

忧虑并非坏事

       据英国《每日电讯报》报道，最新研究显示，忧虑不仅有益大脑功能，并且关乎人类生存。

       科学家对42名患上常见焦虑症的病人进行研究后发现，症状最严重的病人比状况稍好的病人智商要高。

       这项研究已发表在《进化神经系统前沿》杂志上。

       纽约州立大学州南部医学中心的精神病学教授杰瑞米·科普兰称：“归根结底，忧虑使人谨慎行事，因此，他们的生存几率更高。”
