Objective: The association between trigeminal neuralgia (TN) and multiple sclerosis (MS) is well established. In many cases series the frequency of TN is reported in patients with MS but information regarding the frequency of trigeminal pain as a symptom of disease onset is lacking. We present a multi centric analysis of SM-patients affected by TN where we investigated the onset of symptomatology and a current literature analysis.
Patients and Methods: We prospectively acquired clinical and radiological information of patients with MS and with TN that were visited at our clinics in two different departments. A pertinent literature review was carried out as well. We investigated the prevalence of TN in patients with MS and we noted whether facial pain was the symptom of MS onset.
