Sponsor's own description
In this study patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) will receive bright light therapy through portable lamps for 2 weeks. They will either start with this treatment and then go through a wash-out period of two weeks followed by a wait period of two weeks or they will start with the wait period, followed by a wash-out period, followed by the treatment phase. Patients are asked to fill out questionnaires (rating their level of fatigue) and they go through a standardized computer test assessing their attention levels, both at multiple times throughout the study. The aim of this study is to find out if treatment with bright light will improve subjective fatigue levels and objective attention levels inME/CFS patients.
