Preventing chronic pain with stress management
Date:2/24/2013

This release is available in French.

For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition. This is particularly important for people with a smaller-than-average hippocampus, as these individuals seem to be particularly vulnerable to stress. These are the findings of a study by Dr. Pierre Rainville, PhD in Neuropsychology, Researcher at the Research Centre of the Institut universitaire de griatrie de Montral (IUGM) and Professor in the Faculty of Dentistry at Universit de Montral, along with tienne Vachon-Presseau, a PhD student in Neuropsychology. The study appeared in Brain, a journal published by Oxford University Press.

"Cortisol, a hormone produced by the adrenal glands, is sometimes called the 'stress hormone' as it is activated in reaction to stress. Our study shows that a small hippocampal volume is associated with higher cortisol levels, which lead to increased vulnerability to pain and could increase the risk of developing pain chronicity," explained tienne Vachon-Presseau.

As Dr. Pierre Rainville described, "Our research sheds more light on the neurobiological mechanisms of this important relationship between stress and pain. Whether the result of an accident, illness or surgery, pain is often associated with high levels of stress Our findings are useful in that they open up avenues for people who suffer from pain to find treatments that may decrease its impact and perhaps even prevent chronicity. To complement their medical treatment, pain sufferers can also work on their stress management and fear of pain by getting help from a psychologist and trying relaxation or meditation techniques."
