【脑部扫描让你提前知道以后会不会得抑郁症】

【脑部扫描让你提前知道以后会不会得抑郁症】麻省理工学院专家扫描了两组孩子的大脑,一组是家族有抑郁病史的,一组是家庭里没有抑郁症的,发现他们的脑部有明显不同。科学家说可以用此种方法来提前确定抑郁症高发者,从儿童做起,在抑郁症状出现前进行控制从而减少抑郁症患者。

Brain scans could detect depression BEFORE symptoms appear: 'Striking differences' identified in circuits controlling feelings and thinking

  • Scientists scanned two groups of children - one with high risk of depression due to family history and the other with a lower risk of disorder
  • Found 'striking' differences in activity in key areas of the brain, they say
  • Areas are those linked to depression, controlling feelings and thinking
  • Hopes scans could identify those at risk of depression before it hits 

A brain scan could one day be used to diagnose depression, experts have said.

Using the latest advances in brain imaging a team of scientists at Massachusetts Institute of Technology's McGovern Institute were able to identify a group of children at high risk of the debilitating and often deadly disorder.

According to the World Health Organization, an estimated 350 million people of all ages suffer from depression.

It is a serious mental health disorder that affects every aspect of a person's life and in severe cases it can lead to suicide.

Researchers studied two groups of children, one at high risk of depression due to family history and a control group of children at low risk.

Children from both groups were scanned to map the network pathways in their brains.

The question was if the researchers could find differences in brain activity that would be an indicator for a greater risk of depression.

'The answer is there are very great differences,' Professor John Gabrieli, a professor of brain and cognitive sciences at MIT, said.

'We saw differences that were striking in a number of circuits including those that change in depression, including those involved in feelings, other parts that are involved in thinking.

'The additional thing besides seeing these differences were that the differences were so strong child by child that we were very close to perfect with being able to categorize from a brain scan itself whether a child was at risk or not.'

He said the goal going forward is to follow these children to see who among the high risk group goes on to develop depression, tracking changes in their brain function along the way .

'Obviously the children that go on to depression the more we can identify them well the more we are hopeful that we can get preventive treatments going. Not waiting for them to be suffering but helping them beforehand,' said Professor Gabrieli

'So we want to learn both to identify early children who are at true risk, help them before they struggle and learn from those that are resilient what is different about them because that might be a hint about how to help the children that are not resilient,' he added.

The researchers say a better understanding of how depression affects the brain will ultimately lead to better treatment options for those that are most at risk.
