Reaction to pain is not always apparent among patients with Down's syndrome, but new research published in 2 December
A study by Martine Hennequin and colleagues from Université d'Auvergne Clermont-Ferrand Franc, and McGill University, Montreal, Canada measured the latency of pain detection in 75 control individuals and 26 patients with Down's syndrome. They found that patients with Down's syndrome had a significant longer time delay in pain detection to cold stimuli than controls (29 seconds compared to 21 seconds). These patients also had difficulty in localising a cold stimulus on the hand, face and in the mouth when compared to controls.
In the view of these results, researchers are now planning to study the reaction of pain in individuals with more severe and profound cognitive impairment.
