could you elaborate? Do you think they really didn't have the condition described? If they did then while more evidence would be helpful in establishing likelihood, it would not make a difference in establishing possibility.
These cases are extremely interesting, and any high-impact journal would immediately accept a quantitative MRI report or the simplest fMRI study on such a patient (if it were from a reputable source).
This would make the cover of Nature or Science mags, and would capture the attention of the entire neuroscience community. Yet as interesting as they are, none of these existing case studies conform to the standards of modern neuroscience reporting.
