sleep study

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.

First of all, and I say this as not only a patient but as a hcp in the psych field as well as the hospital setting. Do NOT let anyone tell you that you have psychological issues if YOU know you don't Some Doctors lean toward the "psychogenic" rather than trying to find the truth. It becomes the ruin of their patients. Trust me, I have seen this done over and over again to many. Second of all. If your EEG showed the abnormalities, what is your neurologist suggesting be done about it. There are good neurologists, then there are mine. So the question remains with you... There are obvious concerns what is your Dr. recommending or is he like mine? Are there really any good neurologists out there?!?!?!?!

I had a sleep disorder for years, which was blamed first, on my weight (about 20lbs overweight at that time), then, on depression, which I did have, but was not the entire cause of my poor sleep.  I was given depression meds to help keep me awake, to help me sleep, nothing worked to cure the sleep problems.  I couldn't take the meds to help me sleep because I was more exhausted during the day.  Finally, I looked up symptoms on the internet for sleep disorders and "diagnosed" myself with narcolepsy.  I had cataplexy, felt paralysed upon going to sleep or waking up and had other symptoms.  Even after showing the doctor the article and explaining how I felt, I was only givena nighttime sleep study.  I was diagnosed with sleep apnea and CPAP did wonders for about a year. Finally, I was sent to a wonderful doctor, who did a full sleep study and found I had narcolepsy.  I don't think this is what you have, but my point is, doctors don't know everything.  I had gained so much weight do to being tired, my health problems became worst.  Now, I am being treated, have lost weight and am feeling wonderful.  Good luck to you.

Thank you for all of your advice. I have seen a Neurologist who suggested CPAP (during the cpap trial I had a sleep terror!), I hope cpap will help, only time will tell!
