One way in which blood-CSF barrier breaches might be readily (and noninvasively) revealed is by having Fonar Upright MRI scans done of sALS patients.
These findings indicate that both the ST1 and ST104 strains cause bacteremia and sepsis but that the ST1 strains are more likely to cross the blood-CSF barrier and subsequently result in meningitis.
Unfortunately, the author still focuses on the older models of blood-CSF barrier function ("serum leak"), while struggling with the models derived from current understanding of biophysics and protein dynamics.
We included only CSF samples showing no or only minor contamination with erythrocytes (<150/[micro]L), no intrathecal humoral or cellular immune response, and normal or only slightly disturbed blood-CSF barrier as measured by albumin quotient.
To a certain degree, CSF is shielded from nonneurologic protein sources by the blood-CSF barrier and has a relatively slow protein turnover.
