> Was this obvious idea of scanning the brain for brain fog never tried before? > The team led by scientists at the Smurfit Institute of Genetics in Trinity’s School of Genetics and Microbiology and neurologists in the School of Medicine have also uncovered a novel form of MRI scan A typical clinical MRI machine has a resolution of about 2mm. Small lesions are invisible to it. They are expensive to run and, more importantly, a scan takes a long time, so you usually only do some sort of specialized detail measurements, not a detailed "full picture" of everything. MRI machines typically run non-stop to be economically viable (just the helium coolant costs something like 200k$ per year), consequently your research likely competes with other teams', I presume. The contrasting agents able to cross the blood-brain-barrier are not substances without concern. They tend to accumulate in the brain, I guess people may be extra cautious with a hypothesis of hyperimmunity, or leaky blood vessels. I am pretty sure a standard MRI scan of the brain did not show the described clinical evidence before. Also: > Undertaking this complicated clinical research study at a time of national crisis and when our hospital system was under severe pressure is a testament to the skill and resource of our medical trainees and staff.
