  1. Values represent number or mean ± Standard Deviation, MMSE = Mini Mental State Evaluation, IL-6 = circulating Interleukin-6, VAS-F = Visual Analogue Scale for Fatigue, WHOQOL = WHO Quality of Life Questionnaire (F2.2 = "How easily do you get tired?", F2.4 = "How much are you bothered by fatigue?", both scored on a 1-to-5 scale going from 'not at all' to 'extremely').
