Scientists increasingly believe that one of the driving forces in chronic pain — the number one health problem in both prevalence and burden — appears to be the memory of earlier pain. Research published today/this week in Current Biology suggests that there may be variations, based on sex, in the way that pain is remembered in both mice and humans.
The research team, led by colleagues from McGill and University of Toronto Mississauga, found that men (and male mice) remembered earlier painful experiences clearly. As a result, they were stressed and hypersensitive to later pain when returned to the location in which it had earlier been experienced. Women (and female mice) did not seem to be stressed by their earlier experiences of pain. The researchers believe that the robust translational nature of the results, from mice to men, will potentially aid scientists to move forward in their search for future…
