Rayleigh has nystagmus. It's an eye condition, not necessarily a brain condition. Simply put, nystagmus is when the eyes shake. In Rayleigh's case, her eyes only shake occasionally and not constantly. They shake side to side when she looks far to her left or right and I've also seen them rotate back and forth slightly when focusing. Her neuro said that based on what we know about Rayleigh and that she hasn't always had nystagmus that her condition was probably brought on by her seizure control medicines. Nystagmus as a result of seizure control medicine is most commonly attributed to Phenobarbital but can be a side effect of many seizure control medicines including Clobazam which Bug has been on for over a year now.
If Bug's nystagmus is a result of medication she will have the condition for as long as she is on the medication but on that same note, if it is the medicine causing the nystagmus then it will go away if/when she is off that medicine. We are making an appointment with Bug's neuro-opthomologist to find out more about nystagmus.
While we were talking with the neuro about this, Bug did her head drop. The neuro asked if this was the same type of head drop we had shown him on video back in October and we said yes. He then told us that it looked like a seizure and she did the head drop 2 more times in that 2 minute period. The neuro asked questions like when she does them (mostly when she's sleepy but also randomly rarely), how she reacts after a drop (like nothing happened, but sometimes a big head drop takes her a few seconds to recover and "come to") and then I told the neuro about this new thing that Rayleigh as been doing this week. When she's awake she will start smacking her lips, arms will go out slightly and then come back in and eyes blink.
He then confirmed (not 100% without EEG but pretty much) that we are describing myoclonic-astatic seizures.
The "head drops" are a drop seizure.
When she has the myoclonic-astatic seizure followed by a small head drop in the way that Bug does it is similar to last year when she would have a partial seizure that was followed by myoclonic jerks.
So what we thought was 12 weeks of seizure freedom was really just 12 weeks of partial onset seizure freedom.
There are 2 types of medicine that Rayleigh has not tried before that are used to control myoclonic-astatic seizures: Lamictal and Depakote. It could cause more seizures if we start one of these new medicines along with her existing medicines while on the diet. Plus, these both seem to have nasty side effects that are increased in children under 2 years old. But we know what's next to take if we have to get there.
The current plan is this: We have already increased her dose of Trileptal back up to 1/2 pill morning and 1 full pill at night along with the 1 pill of Clobazam 3 times a day. We can go up higher on the Trileptal if we need to. We will also be upping the ratio on her diet which has shown a lot of success in many cases.
The neuro says that there are several explanations for why Bug's seizures went from ONLY happening during sleep to completing changing form and happening awake. The most likely reason being that her brain is maturing as she grows older. The least likely reason being the diet.
The only good thing to take away from knowing that these have been seizures is that they do not physically hurt her or affect her mood. I do still believe that they are hindering her development though :(
The neuro is ordering an EEG with an immediate visit with him right after it's done to discuss results so I'll repost after that. It should be within the next 2 weeks. Until then, we will love our Bug just the same and enjoy Christmas with her!
