One of the most profound, although seemingly minor, changes for my husband, now 18 months since his venoplasty for jugular and dural sinus stenosis--has been the return of dreaming. After his procedure, he would wake up in the morning and recount for me his vivid dream from the night before. It was so strange to us...he realized that for several years, he couldn't remember his dreams.
He was now sleeping soundly, no longer spasming or waking up gasping for air. And in this deep sleep, his dreams had returned.

When I went to the CCSVI international symposium in Bologna last year, Dr. Salvi got up and spoke about the changes in his patients after angioplasty. And one of the global differences his patients noted was deeper, more restful sleep, and the return of dreams. He had a wonderful illustration that came on the screen during his power-point-- a cartoon of a person deeply sleeping, smiling, with a colorful dream bubble over their head. I almost leapt out of my seat. "That's happened to Jeff!" I whisper/exclaimed to Dr. Dake, seated on my left. "He's dreaming again."
Now, I read time and time again from patients and their caregivers about the return of deep, restful sleep and dreaming. I realize that dreaming might not seem important in the grand scheme of recovery from MS....but I believe it is. I believe it is proof of a brain that is healing. A brain that does not have REM (rapid eye movement) sleep, does not dream. There is research that links dreams, REM sleep and oxygenation.
"REM sleep time is strongly reduced by hypoxic and increased by hyperoxic atmosphere, in accordance with the existence of an O2 diffusion limitation. Any pathological decrease in arterial PO2 and/or O2 delivery creates a specific risk in REM sleep."

During REM sleep, there is an increase in blood flow to the limbic system and the brain stem, with circulation to these structures decreasing during non-REM sleep. As brain activity increases during REM sleep, the cerebral requirements for glucose and oxygen both increase....
