Pain is one of the most disabling clinical symptoms in patients with multiple sclerosis (MS). Several studies have already assessed the prevalence of pain in MS patients, reporting variable results, probably due to methodological differences. The aim of this single-centre cross-sectional study was to define the prevalence and characteristics of chronic pain in a population of MS patients using validated tools, and to analyse these data in relation to demographic and clinical features, including disease duration and disability (EDSS and its single functional system scores). ⋯ Patients with chronic pain and, in particular, patients with neuropathic pain had significantly higher EDSS scores than those without pain. Only 24% of patients with chronic pain and 33% of patients with neuropathic pain were on a specific long-lasting treatment for pain. The present study supports the routine assessment of neuropathic pain in MS patients, especially in those with a sensory functional system involvement, in order to avoid underdiagnosing and undertreating a potentially disabling condition.

The comorbidity of headache and epilepsy is often seen in neurological practice. The objective of this study was to assess the prevalence, types of, and risk factors for headache in juvenile myoclonic epilepsy (JME). We assessed a total of 200 patients and 100 healthy controls in our study. ⋯ However, migraine frequency was higher in JME patients than healthy controls. Some migraine and TTH characteristics were different in between groups. We suggest that our results support both genetic relationship and shared underlying hypothetical pathopysiological mechanisms between JME and headache, especially migraine.
