A study of psychological well-being in people with multiple sclerosis and their primary caregivers.

Background: Multiple sclerosis (MS) is the most common disabling disease of the central nervous system. In these patients, fatigue is the most common symptom that causes disorder in the work, social activities and daily functions of the patients. Given the assumption that MS reduces the patients' psychological well-being, this study aimed at assessing the psychological well-being of both the patients and their primary caregivers.
