My wife, Doris (73,3) has been taking oxygen because of a worsening pulmonary shunt. The consequences for her Parkinson's has been remarkable. Her insomnia which has plagued her terribly, has been sharply reduced. Her Restless legs have almost disappeared. Her dyskinesia has been greatly diminished. She has been maintaining her sinemet regimen. Has anyone else been taking oxygen for other conditions and have they found that it affects their parkison symptom? In a couple of weeks she will undertake a procedure to minimize the effects of the pulmonary shift. The consequence should be a substantial increase in the natural volume of oxygenated blood in her system. Hopefully the symptomatic relief that she has received with the oxygen supplement will persist. I am not suggesting that anyone should experiment with oxygen therapy, but I am searching for more information. Jules
