A clinician may often depend upon patient history and exam to diagnose, for example: discharge of excessive amount of clear fluid from the nose upon bending over, the increase in headache following a Valsalva maneuver or the reduction of headache when the patient takes a prone position are positive indicators.
Aqueductal stenosis is a narrowing of the aqueduct of Sylvius which blocks the flow of cerebrospinal fluid (CSF) in the ventricular system.Blockage of the aqueduct can lead to hydrocephalus, specifically as a common cause of congenital and/or obstructive hydrocephalus.
Treatment based on the idea of CCSVI is considered experimental. [6] Balloon dilatation of stenosed jugular vein in a MS patient. Stenosis prevents the balloon from inflating (in the middle) while pressure is low. Further trials are required to determine if the benefits, if any, of the procedure outweigh its risks. [22]

Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
There are a few different ways to relieve sinus pressure. One of the most common methods is to take an over-the-counter decongestant. Decongestants help to reduce the inflammation in the sinuses ...
At the proximal end, the shunt valve can become blocked due to the buildup of excess protein in the CSF. The extra protein will collect at the point of drainage and slowly clog the valve. The shunt can also become blocked at the distal end if the shunt is pulled out of the abdominal cavity (in the case of VP shunts), or from similar protein ...
Another treatment for obstructive hydrocephalus is an endoscopic third ventriculostomy (ETV). This surgery creates an opening in the floor of the third ventricle so that CSF flows directly to the basal cisterns. This treatment can shortcut any obstruction like aqueductal stenosis. This may or may not be appropriate based on individual anatomy.
