Hey mamab, welcome to CWE.
It's great that you are being proactive in finding for answers about your daughter's health. How frustrating that her doctors aren't on the same page. If you can, seek out additional medical doctors to take a look at her case. Has she seen an epileptologist (epilepsy specialist)? They tend to do a better job when ruling epilepsy in or out as a diagnosis.
Has your daughter had an EEG? A negative EEG won't rule epilepsy out, but a positive one could confirm such a diagnosis and suggest treatment.
She was on Cyclobenzapine, Gabapentin, Nortriptyline, and Botox for headaches prior.
By prior, do you mean before the initial seizures? Or do you mean she was put on the meds afterwards by the physical and/or psych doctors? I ask because some medications can cause seizures and [i[stopping[/i] some medications too quickly can also cause seizures.
The botox for headaches suggests that she has migraines, is that right? Migraines are considered a close cousin of epilepsy, and some of the symptoms can be similar. Does anyone one else in your family suffer from migraines or seizures? That could be another indication of a possible epilepsy diagnosis.
Was there a precipitating event for the loss of feeling in her legs? Did it happen immediately after a seizure? Has she had MRI or CT scans to make sure there is no neurological cause for the paralysis? Has had an electromyography test (sensors are used to measure electrical activity in the muscles) to determine where the paralysis is occurring -- in other words is it a joint issue, a spinal issue, or a brain issue? Does she have some control over the muscles -- can she use the bathroom, etc.?
These are all factors the doctors should be taking into consideration when making a diagnosis and finding a treatment.
