From Dr Flanagan.
The role of the autonomic nervous system is a complex topic. Suffice it to say that the autonomic nervous system is known to fail in cases of high intracranial pressure such as traumatic brain injuries and strokes. It can also fail from arterial hypertension (high blood pressure). Some researchers suspect that hypertension and autonomic failture play a role in NPH. I further suspect that NPH may cause autonomic dysfunction which I am currently discussing on my website regarding the third ventricle. I also suspect the venous blood and CSF drainage problems can cause brain edema and NPH.
