Long-term bullying causes a part of the brain to atrophy



The experience of being bullied as a child has been memorable for decades. Undark, a scientific media, explains “the effect of bullying on the brain ”.

How Bullying May Shape Adolescent Brains

Bullying is now seen as a global problem. In January 2018, the United Nations Educational, Scientific and Cultural Organization (UNESCO) Statistical Institute announced that nearly a third of the world's teenagers had experienced bullying.

Trauma caused by bullying, etc. affects the victims, such as decreased academic performance, increased unemployment, depression, anxiety, stress disorder, drug abuse, self-harm, and suicide Cause The impact is known to last for many years, and the scope of the impact covers a wide area such as health, finance, education level, and BMI.

Most neuroscience research on bullying has been done in the last decade and is an emerging research area. The paper published in December 2018 was published as part of an EU-based research project called ` ` IMAGEN '' at Kings College London, UK. '.

In the study, 682 young people from France, Germany, Ireland, and the UK were subject to a

longitudinal examination of brain diagnosis by MRI and a survey of stress and abuse by questionnaire. Subjects responded to questionnaires about bullying in daily life at the age of 14, 16, and 19, and MRI scans were taken at the age of 14 and 19.

As a result of the survey, the research team identified nine places that are considered to be related to bullying. In addition, subjects who experienced bullying over time found that the volume of the left brain side of the putamen and caudate nucleus associated with movement and learning was significantly reduced. According to Erin Burke Quinlan, the lead author of the study, this atrophy is `` it is still unknown whether it is temporary or permanent '', the research team will continue to examine the subject's brain It's a schedule.

Quinlan's study does not conclude which biological mechanism has altered brain volume. Professor Tracy Vaillancourt, who is studying child mental health and abuse prevention at the University of Ottawa, Canada, says brain atrophy may be caused by the stress hormone “cortisol”.

According to professor Vaillancourt, young people who have been abused or bullied are known to experience low levels of normal cortisol as a result of chronic stress-induced cortisol. This phenomenon is seen not only by bullied youth, but also by returning soldiers, victims of sexual assault, and those who were imprisoned in concentration camps.

Professor Vaillancourt said, “Neurobiological research on abuse is 15 years later than research on the psychology of abuse because the abused child says that he was sad”. Insist. ' Professor Vaillancourt says that one of the reasons for the increase in neurobiological research on abuse was 'providing Congress with scanned images of brains that were actually atrophied by abuse' “The neurobiological research on bullying will move forward,” says that this research provided physical evidence that bullying causes atrophy of the brain.
