Dela sleep

  : Few months ago, I have had a sleep study and the was that I had no delta sleep at all. I was told bu my neurologist that there was no cure for such a disease. Is it true?

I am not a sleep specialist, but since one of my colleagues has not answered this question by now, I'll take a crack at it.
When you have an EEG done, there are a variety of "brain waves" that are recorded. The appearance of these recordings changes in wakefulness and in various stages of sleep. In fact, each stage of sleep is identified by patterns on the EEG.
In the deeper stages of sleep (stages 3 and 4), there are some very slow waves (1-2 per second) which are referred to as "delta" waves. This is distinct from the "alpha" wave pattern (8-10 per second) in full wakefulness or "theta" wave pattern (5-6 per second) seen in drowsiness or the lighter stages of sleep.
REM sleep is characterized by the rapid eye movements - this is when you ddream.
I'm not sure what is meant by a lack of delta wave sleep. It could be that none was detected when you fell asleep. Does that mean you NEVER have delta wave sleep? I doubt it, but don't know. Were they trying to tell you that you had REM sleep "out of order" that is immediately upon falling asleep? Was the test too short? Was there interference from pharmacologic agents?
As you can see, there are too many unknowns. Lack of delta wave sleep is not a disease per se. It would be just part of a sleep disorder which could be more precisely defined. If you have not received enough information from your sleep specialist, then it may be appropriate to have a second opinion.
You are welcome to call 800 223 2273 and ask for neurology appointments at 4-5559. Tell them you want a second opinion with a sleep disorders specialist. I hope this helps. CCF MD mdf.
