One could therefore propose that a reason for this greater frequency is because neuroepithelial disruption could occur more slowly during the onset stage in some types of hydrocephalus; thus the anomalous presence of AQP4 in the CSF would be longer and the parenchymal-CSF barrier disruption (transparenchymal pathway) during this time would allow more brain AQP4 to be in contact with lymphocytes in encephalic regions where this does not normally occur and where brain AQP4 is unrecognized and consequently autoantibodies (AQP4-Ab) might be generated which would then attack the AQP4 surrounding the optic nerve, in the ciliary body and on the ventricular surface of the sylvian aqueduct, and thereby trigger NMO and noncommunicating hydrocephalus.
Because the lesions tend to obstruct the foramen of Monro, patients present with signs and symptoms of noncommunicating hydrocephalus. Symptoms may develop rapidly or progress slowly and may include severe pounding headaches; visual changes such as blurring, visual field deficits, or double vision; and nausea, vomiting, or both.
