Some of the symptoms of the autistic condition Asperger Syndrome, such as a need for routine and resistance to change, could be linked to levels of the stress hormone cortisol, suggests new research led by the universities of Bristol and Bath.
Normally, people have a surge of this hormone shortly after waking, with levels gradually decreasing throughout the day. It is thought this surge makes the brain alert, preparing the body for the day and helping the person to be aware of changes happening around them.
However, a study by Dr David Jessop from the University of Bristol and Drs Mark Brosnan and Julie Turner-Cobb from the Department of Psychology at the University of Bath, has found that children with Asperger Syndrome (AS) do not experience this surge.
