Flooded brains: Swamped by ion pumps? or by venous insufficiencies?, by Dr. F. Schelling March 2016

"...Conclusion
Hladky and Barrand’s treatise makes plain: The interactions between cerebral venous and ISF respectively CSF dynamics have not been considered as carefully and studied as thoroughly as the subject deserves.
Taking a closer look at what happens, in unexplainable cerebral affections, along both the extra- and intracranial cerebral venous passages may hold staggering surprises. Not only in patients with communicating hydrocephalus."
