Our sleep apnea and nocturnal epilepsy related?

Yes and no. Patients who have epilepsy and seizure activity and have obstructive apnea can see an increase in seizure activity if the apnea is untreated.
Yes. But consult with your sleep specialist regarding your case.
No. Nocturnal epilepsy is a seizure disorder in which seizures occur only while sleeping. Sleep apnea is not a seizure disorder.

I just had a sleep study that revealed bad sleep apnea. Also it said that I had epileptic seizures in my brain. What does that mean?

Complicated question. Sleep apnea means that you stop breathing for periods of time while you sleep. Epileptic seizures mean that your brain activity goes through jolts that can cause movements in your body, loss of consciousness and behavioral changes. The most important thing is to ask your physician to carefully explain this to you without medical language. It's important that you get good treatment for both.
Must seek treatment. Often epilepsy and obstructive sleep apnea (osa) go hand in hand. Sleep problems are a double-edged sword; epilepsy disturbs sleep and sleep deprivation aggravates epilepsy. People who experience involuntary movement while they sleep tend to wake up tired and without energy in the morning. Deprivation of sleep over prolonged periods of time can cause cardiac arrhythmia, or irregular beating.
Not uncommon. Not uncommon situation. Asleep seizures can cause sleep problems. Make sure your sleep doc explains the problems and recommends the next step.

While my friends sleeps he foams at the mouth and freezes. Could this be nocturnal epilepsy?

Does not sound norma. That is certainly a possiblity and there are other "parasomnias" that can cause this behavior. This is easily clarified with a sleep study which a primary care doctor can arrange. During a sleep study brain waves and patterns are measured and epileptic behavior would likely be detected. It would also be noteworthy to keep a log before any appointment as to how he feels after sleeping like that.
Need neuro eval. Recording his sleep with eeg would be the answer. If one of these events can be caught on the eeg, it would answer whether they are seizures. They could be sleep related events of an non-epileptic nature. Have him get a thorough medical evaluation and recommend a referral for neurological evaluation.
Nocturnal Epilepsy. Yes. Have him see a neurologist. If they check an EEG they may not notice a problem esp if he is awaken during the testing. In my practice when I am concerned that my patient has seizures in sleep I strongly consider an overnight EEG - can be in hospital or at home. Unfortunately, at home overnight EEGs (AEEG) are not available everywhere.
