Kawatani, Junko, Mizuno, Kei, Shiraishi, Seishi et al.·Brain & development·2011
This study looked at thinking and attention problems in children with ME/CFS using a specialized test that measures how quickly and accurately the brain can process information. Children with ME/CFS performed worse on attention tasks compared to healthy children, especially when they had to switch between different tasks. After 6 months of combined treatment with therapy and medication, children showed improvements in both their thinking ability and fatigue levels.
