The paper https://doi.org/10.24019/jtavr.29 addresses only the point of how a one-sided valvular incompetence of the internal jugular veins endangers the brain. It must not be forgotten, though: the blood contained in the jugulars is driven in direction of the brain as often as these veins are impacted upon - but can't empty themselves, quickly enough, in the normal way.

The hemodynamics of the human brain won't ever be understood ... if the intracranial venous anatomy is not contemplated in its natural context with the extracranial venous and perivenous anatomy and especially its functional changes; the position-dependent strictures and at times tempestuous impacts which the cerebral venous passages located outside the skull are exposed to. Rather than in replacing Newtonian principles with statistical ones, we might make progress in coming to terms with the individually given intricacies of venous hemodynamics. Admittedly a tedious task, showing a humbling underdevelopment of venous computational hemodynamics.

This study is important in relationship to how lymph from the brain is deposited back into the blood stream, as this occurs at the junction where the jugular valve is located. Lymph, CSF and blood all go thru this area, and if there is reflux or slowed flow, the brain is negatively affected.
