It has been ordered that I have an enhanced sleep study by a new physician who specializes in neurally mediated sleep disorders. I wondered if anyone else has been tested by multiple types of sleep studies and their experience with such. My first one was ordered and conducted by a pulmonary specialist who also performed sleep studies. It was explained to me by this new doctor that the particular study I had previously did not measure the neural symptoms as the one he is ordering. Something about the number of leads used and the atmosphere in which the study is performed. Does anyone have any knowledge of this study and any info as what may or may not be shown by it. It may be some time before I am acxtually tested as the other one was done in February and it may not be possible to perform within such a short time frame due to insurnace provider guidelines. Gee just something else to worry about.
