Interesting topic - a very clinical/medical perspective on a neurological condition. This seems like a very complicated topic but you organized it well with your breakdown of categories. Great use of video and figures too. It would have been nice if you linked to other neurowikis or external pages about the treatment of Gliomas (I'd definitely like to read further on that).
This is the discussion related to the wiki page Clinical Presentation and Molecular Diagnosis of Glioma.
