Delayed recall has just kicked in and I can understand what you are saying clearly.
The thought that I have is that the important parts of the brain functionally seem very close to the largest areas or room for fluid expansion.
**Are the Thalamus and Hypothalamus adjacent to the CSF fluid reservoirs/ventricles and at risk of crushing from CCSVI back jets and reflux, therefore compression of the CSF within the Skull?**
**Would it would link the observations of Franz Schelling and also BNAC's recent 2 study findings where the damage (atrophy of the Thalamus and Hypothalamus) is found most commonly in CCSVI and 'MS', and most likely to be symptomatic?**
** Would the back jets from the Spinal Cord (the Oppenheimer upper cervical MS lesions) also be projecting/squirting to the same area with in Brain, the ventricles, which 'captures' the fluid expansion because of location and size?"
Quotes from your article Dr F that switched on the lights of thought;http://uprightdoctor.wordpress.com/
"Ventriculomegaly can be caused by anything that obstructs the pathways and normal flow of CSF, or it can be caused by inadequate absorption of CSF"
"Sometimes they are simply referred to as a syrinx. For now suffice it to say, they are abnormal cavities in the cord that are probably caused by pressure problems within the cord, similar to hydrocephalus which is due to pressure problems in the brain."
"The arachnoid granulations are one-way valves that connect the subarachnoid space to the superior sagittal sinus. The superior sagittal sinus is part of the venous drainage system of the brain located at the top of the skull."
"Likewise, ventriculomegaly seen in neurodegenerative diseases such as Alzheimer’s, Parkinson’s and multiple sclerosis is typically attributed to atrophy of periventricular structures that surround the ventricles. Ventriculomegaly seen in NPH, on the other hand, is typically attributed to enlargement of the ventricles without atrophy of the surrounding tissues and structures. The problem is, the ventricles don’t always return to normal size when excess CSF volume is surgically decreased with a shunt. This led researchers to suggest that, the sustained enlargement of the ventricles may be due to permanent damage to the surrounding periventricular structures as a result of the NPH."
"There are two primary theories regarding the origin of NPH. The first theory has to do with obstruction of CSF flow or blockage of resorption into the venous drainage system of the brain discussed above. The other theory is that NPH is due to atrophy of surrounding structures, such as the periventricular white matter that gets strained and tensioned to the point of breaking, causing the walls of the ventricles to weaken and enlarge. Enlargement of the ventricles also stretches, strains and compresses surrounding blood vessels that can decrease blood flow and cause ischemic tissue damage. In either case, the subsequent weakness in the walls of the ventricles and surrounding structures cause the ventricles to enlarge. NPH, in turn, increases tension, tangential and shear stresses in the brain, as well as compression loads caused by expansion and contraction of the brain with each beat of the heart that forces a relatively large volume of fluid into the mostly closed container of the cranial vault."
"Aside from internal problems in CSF pathways of the brain inside the cranial vault, researchers now suspect that one of the causes of hydrocephalus in children and adults is a dissociation of CSF flow between the cranial vault and spinal canal. Dissociation simply means that the normal flow between the two compartments is disrupted, and as a result they react independantly. Among other things, this can cause potentially destructive abnormal increases in CSF pressure waves in the brain and cord. Dissociation of CSF flow between the two compartments may similarly play a role in hydromyelia and other conditions of the cord."
"Upright posture requires proper CSF flow between the cranial and spinal compartments in order to maintain the correct volume, pressure, protection and bouyancy of the brain. Excess CSF volume in the ventricles, cisterns and subarachnoid spaces can cause destructive tension (stretch) and compression loads in the brain. An insufficient volume reduces bouyancy, which causes the brain to sink and make contact with the base of the skull. The connection between the cranial compartment and spinal compartment is in the upper cervical spine. Malformations, injuries and misalignments of the upper cervical spine can cause a dissociation of CSF flow between the cranial and spinal compartment. Further below in the lower spine, spondylosis (degeneration), scoliosis (abnormal curvature) and stenosis (narrowing) alter the design of the spinal canal and thus affect blood and CSF flow. The changes in the design of the spinal canal can, likewise, result in a dissociation of CSF flow between the cranial vault and spinal canal. Thus far, the studies on dissociation of CSF flow between the cranial vault and spinal canal have all been done using supine MRI. Future research will need to be done using upright MRI. Upright MRI will most likely reveal much more about the destructive consequences of dissociation of CSF flow between the cranial vault and spinal canal."
"The areas hardest hit by faulty fluid mechanics in the cranial vault are: 1) the periventricular structures that surround the ventricles, 2) the bottom surfaces of the brain, brainstem and cerebellum located above the base of the skull that are surrounded and supported by the cisterns, and 3) the cortex of the brain closest to the inner surface of the skull. The particular areas that are affected are determined by the cause and the consequences of the faulty CSF flow."
