A study from Stanford University in the USA suggests that very stressful events affect the brains of boys and girls in different ways. Researchers say that girls suffer more after traumatic events and are more likely to develop post-traumatic stress disorder (PTSD). They also say that because of this, girls and boys should be treated differently by doctors during the recovery process from PTSD. Lead researcher Dr Megan Klabunde said: "It is important that people who work with traumatised youth consider the sex differences. Our findings suggest it is possible that boys and girls could exhibit different trauma symptoms and that they might benefit from different approaches to treatment."

來自美國斯坦福大學(xué)一項研究表明，非常有壓力的事件對男孩和女孩的大腦有著不同的影響。研究人員表示，創(chuàng)傷性事件過后，女孩遭受更多痛苦，更有可能患上創(chuàng)傷后應(yīng)激障礙(PTSD)。他們還說，鑒于這個原因，在PTSD的恢復(fù)過程中，醫(yī)生應(yīng)該對男孩和女孩采取不同的治療方法。首席研究人員Megan Klabunde表示：“對經(jīng)歷創(chuàng)傷的青少年進行治療的醫(yī)生應(yīng)該考慮性別差異，這一點非常重要。我們的發(fā)現(xiàn)表明，男孩和女孩表現(xiàn)出不同的創(chuàng)傷征兆，他們或許能夠從不同的治療方法中獲益。”

The research focused on a part of the brain that deals with emotions and empathy, called the insula. The smaller the insula, the more likely it is that someone will suffer from PTSD. Researchers discovered that the insula was particularly small in girls who had gone through a traumatic event. It was larger than usual in boys who had experienced a distressing, shocking or frightening event. Post-traumatic stress disorder is a mental disorder that can develop after traumatic events, such as sexual assault, warfare, traffic collisions, or threats on a person's life. Symptoms may include disturbing or suicidal thoughts, nightmares related to the events, and alterations to how a person thinks and feels.

這項研究集中關(guān)注了大腦處理情感和移情的部位，腦島。腦島越小，患上PTSD的可能性越大。研究人員發(fā)現(xiàn)，曾經(jīng)經(jīng)歷創(chuàng)傷事件的女孩的腦島特別小。而經(jīng)歷過痛苦，震驚或恐嚇性事件的男孩的腦島則比平常更大。創(chuàng)傷后應(yīng)激障礙是遭遇創(chuàng)傷事件后患上的一種精神疾病，比如性侵，戰(zhàn)爭，交通事故或者生命安全受到威脅。癥狀包括思維混亂，有自殺傾向，與這些事件有關(guān)的噩夢，想法和感覺發(fā)生改變。
