sleep study
by Sleepquest, Jul 11, 2006 12:00AM
Hello,
I have had two sleep studies one year apart in different sleep studies in different states.
First sleep study:
Stage 1 21.5%
stage 2 and delta normal
no Rem sleep
sleep onset delayed (278 mins)
sleep efficiency 26.3%
No apneia /hypopnea
Impression: Technically this is a very poor EEG due to restlessness and frequent arousals. While the patient did exhibit abnormal movements (my note: running like movements) it does not appear that there were paroxysmal abnormalities seen on the EEG. Patient was awake during these episodes. psyscological evaluation is recommended.
I was taking Klonopin 1mg before this study and stopped taking it three days before the study.
My second sleep study staged as:
Stage 1 42%
stage 2 11.9%
stage 3 0
stage 4 0
Rem 16.5%
sleep onset 122.5 mins
sleep effiency 42%
AHI index 88.71 per hour
Impression Moderate to severe sleep disordered breathing with desaturation to 89% (CPAP recommended) We would recommend further evaluation for the jerking activity seen during sleep. (appeared to related to Hyponea)
Three years ago I start having vioent shaking activity after waking up from sleep and then a little later sleep terrors. I am still having these episodes.
I am a 32 year old female who is fit and enjoys running, biking.
I am no longer taking klonopin
Why are my two sleep studies so different. Can you shed any light on my first sleep study.

Please keep in mind that I am unable to diagnose you since I am unalbe to examine you, this forum is for educational purposes only. The information you provided on your sleep studies both relate that your sleep was light (Stage I or II only) frequently interrupted and it was a long time before you reached sleep. You also had some jerking type movements that niether sleep study was able to characterize. Your first sleep study remarked that there was no EEG change with your motions (no seizure activity) and the second study did not comment on EEG at all. Your first study related no problems with breathing, while your second study related a desat to 89%, mild drop in oxygen content). It is very difficult to compare these 2 studies since they were collected with different data. There are several things that can cause thrashing movements at night including REM sleep behavior disorders (acting out your dreams), seizures, and restless leg syndrome. Different specialty doctors conduct sleep studies (Pulmonary, Psychiatrist, and Neurologist) to address your problem with thrashing at night I would suggest a consultation with a Neurolgist that specializes in Sleep disorders. As far as your need for CPAP it depends on your clinical presentation, daytime sleepiness, head and neck anatomy etc and based on the results of your second study suggests that you would benefit from CPAP. If it is confirmed that you require CPAP for obstructive sleep apnea, please keep in mind that untreated, disordered sleep can result in long term health effects including contributing to fibromyalgia and hypertension. I hope this was helpful.
Staging for second sleep study
Stage 1 11.9%
Stage 2 64.2%
Stage 3 0
Stage 4 0
Rem 16.5%
What are your views on this?
Thanks.
Bye sleep terror I mean I woke myself up screaming. This was diagnosed as a sleep terror, I beleive this is different than sleep paralysis, sorry I could not be of more help.
