Hanssen DJC, et al. - Researchers performed a comparison of chronic pain characteristics of older patients with Medically Unexplained Symptoms (MUS), to those of patients with Medically Explained Symptoms (MES), and to those of patients with Major Depressive Disorder (MDD). With respect to the chronic pain characteristics, older MUS-patients did not differ from MDD-patients. However, when compared to older MES-patients, older MUS-patients had more intense and disabling pain, and more pain locations.
