Examples of CPAP Data With Seizures ?

Hi Everyone

My wife and two kids may have a rare form of epilepsy. All three have been prescribed CPAPS.

My son had seizure activity under EEG at age 6 but his first observable seizure seems to have been a medication provoked one at age 16(about 6 weeks ago). The dose was so small, it must have turned a non-observable one into a full convulsive one.

After the Age 6 EEG he went on Valproic acid. Later a neurologist wrote that "Valproic acid does not control seizures in that part of the brain" when discontinuing another neurologist's prescription. Valproic Acid is a general purpose anti-seizure med.

However, He no longer has the data and does not know what part of the brain that was. We are waiting for another EEG.

My wife thinks she had a seizure last night while asleep. Scrolling through her data some things look a bit suspicious but not enough to share a screenshot with you.

Does anyone have a picture of what a seizure looks like with CPAP data? I know it is not EEG data but it still might help.

Thanks for reading-Pat

my best bet would be to use the search function to see if anything comes up from past posts. Do you know if your wife or kids had any seizures during their overnight titration study? The doctor might have a copy of that and you could use that as a baseline study in comparison to Oscar.

Thanks kbh209

My wife and son have had multiple sleep studies and they showed no seizure activity but they use far fewer probes than an EEG.

My son's EEG did show seizure activity but it was 10 years ago and the data seems to be lost. It sounds like the seizure activity was in a strange location.

I did search for some time before posting here. I found lots of EEG printouts but not what a seizure might look like with CPAP data.

Happy New Year!

Not an expert by any means, so take my anecdotal advice with a grain of salt.

Epilepsy runs in my family. It’s hard enough to catch seizures on an EEG, I doubt that the data from a CPAP would show anything meaningful.

For future sleep studies for your wife and son they should add full EEG monitoring, it can be done and should be done considering their history. There is also some type of ambulatory EEG they can send home to wear while you’re asleep, don’t remember all the details but some of my relatives have had the ambulatory nighttime monitoring and it caught seizure activity that previous EEGs didn’t find. Good luck!

Various respiratory disturbances are discussed in this study. What you might see are apneas and changes in respiratory rates. But, you are not going to be able to look at these events and say they are seizures. If you knew exactly when the seizure occurred, you could look at that point on a CPAP graph to see if the seizure caused respiratory disturbances.

The aim of this study was to observe any changes in cardiac and respiratory function that occur during seizures. Thirty-seven children (20 boys, 17 girls; median age, 7 years 6 months; range, 1 year 6 months to 15 years 6 months) were studied. We recorded electroencephalograms, respiratory rate, heart rate, electrocardiograms, blood pressure, oxygen saturation, heart rate variability (time-domain analysis), and cardiac vagal tone. A respiratory pause was defined as an interruption in respiration lasting more than 3 seconds but less than 15 seconds. Apnea was defined as absence of respiration for more than 15 seconds. Tachypnea was defined as a 10% increase in respiratory rate from the preictal baseline. Bradypnea was defined as a 10% decrease in respiratory rate from the preictal baseline. Significant hypoxia was defined as a saturation of less than 85%. A significant change in heart rate was taken as a 10% increase or decrease below the baseline rate. Data were obtained from 101 seizures: 40 focal seizures, 21 generalized seizures, and 40 absences. Focal seizures were frequently associated with significant respiratory abnormalities, tachypnea in 56%, apnea in 30%, frequent respiratory pauses in 70%, and significant hypoxemia in 40%. The changes seen in respiratory rate were statistically significant. Changes in cardiac parameters, an increase or decrease in heart rate, were observed in only 26% of focal seizures and 48% of generalized seizures. We conclude that seizure activity can disrupt normal physiologic regulation and control of respiratory and cardiac activity.

Wow, ChicagoGranny, you dug up a treasure chest in response to the OP's question with this one. Very informative. I know they will be very appreciative. I remember having a similar type question in regards to if my limb movements could be reflected in breathing changes in my cpap data, and was very appreciative of the informative discussion around a similar type article.
