Brain Wave Study Results
by Karen__0__0, Apr 23, 1998 12:00AM
What does it mean if a person has an"abnormally rapid EEG" during a Sleep Study? Is this caused by Sleep Apnea itself and would you find this in all persons' who are diagnosed with Sleep Disorders? I have the impression .that it can be worrisome. Why??? Does this imply some
stroke or pre-stroke concern? I am not on any medications. Should this
be followed up in some way; by whom? Thank You

Numerous parameters are judged within the EEG as part of a sleep study, and it
it is not clear which part of the EEG the comment refers to, is it the overall
rythym, background rythym etc ?
This is not part of the routine findings in sleep apnea and is not associated with
sleep disorders in general, there is no reason to suggest any association with
an increased risk of stroke.
The finding may simply be a normal variant without any pathological significance.
Since the EEG recording performed as part of a sleep study is usually quite
limited and records from only a limited area of the brain the best way to
study this further would be to have a full routine EEG specifically to
address this issue. The comment on the EEg is usually only a peripheral
issue in a sleep study,so a specific look at the EEG is probably the best course.
