This study tested whether a telephone-based brain function test could accurately detect thinking problems in people with ME/CFS. Researchers compared two versions of the same test—one on a computer and one done by telephone—in 30 people with ME/CFS and 30 healthy people. Both versions showed that people with ME/CFS were significantly slower at thinking tasks involving attention, memory, and focus, confirming that cognitive problems are real and measurable in this illness.
