Health: New Light on Brain

Scientists said they have identified a section of the brain which, when damaged by stress hormones, can cause the onset of dementia.

High levels of stress hormone were found to shrink the anterior cingulate cortex at the centre of the brain.

Researchers at the University of Edinburgh say brain scans showing a shrunken cingulate indicates you could develop Alzheimer's in the future. It is the first time the link has been found in human brains.

The study's author, Dr Alasdair MacLullich said he was "very excited" by the GBP 130,000 study's findings.

According to the scientists, this could be a marker, an indicator that your brain might go wrong in the future.
