Hi cleareaching~
Changes in ambient pressure can induce the same symptoms found in MS. The term used to describe medical conditions resulting from changes in ambient pressure is "dysbarism".
Webster’s Dictionary gives the definition of dysbarism as, “A reaction to a sudden change in environmental pressure, such as rapid exposure to the lower atmospheric pressures of high altitudes. It is marked by symptoms similar to those of decompression sickness.”
Webster’s Dictionary continues: “Nitrogen narcosis—Nitrogen comprises 79% of the air breathed by aerobic organisms, but at surface pressures it has no sedating effect. At greater depths, however, nitrogen affects the brain in precisely the same way as nitrous oxide (also known as laughing gas).”
Nitrous oxide inactivates vitamin B12, which research shows is linked to many of the symptoms associated with MS. For instance, symptoms of vitamin B12 deficiency, including sensory neuropathy, myelopathy, and encephalopathy, can occur within days or weeks of exposure to nitrous oxide anesthesia in people with subclinical vitamin B12 deficiency.
In the study entitled, Neurologic degeneration associated with nitrous oxide anesthesia in patients with vitamin B12 deficiency," the researchers stated, "Patients with vitamin B12 deficiency are exceedingly sensitive to neurologic degneration following nitrous oxide anesthesia" (Flippo, 1999).
Research has found that patients with MS are unable to properly metabolize vitamin B12. Under the thread "Some Interesting Connections" I am discussing the reason for this.
