Not long after the IOM report was published, NIH issued its own written assessment, concluding that research has neglected many of the biological factors behind ME/CFS and urging more basic science aimed at teasing out the mechanisms of the disease. Collins also announced a "strengthening" of the agency's ME/CFS effort. He moved oversight of the research out of the agency's small Office of Research on Women's Health and into the $1.7 billion National Institute of Neurological Disorders and Stroke (NINDS), and launched an intramural study that began enrolling people late last month. Forty patients who have developed the disease within the last 5 years, after an infection, will be run through a battery of exams at the Clinical Center, the NIH's research hospital. The assessments, from exercise stress tests to brain magnetic resonance imaging tests, will probe the biological and clinical characteristics of the disease—for which there is not even a broadly agreed-upon definition. For comparison, the study will also include healthy controls and people who have recovered from Lyme disease, which can cause similar symptoms.
