First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
Temporal lobe epilepsy can cause memory problems, personality changes, feelings of depersonalization, language problems and/or hallucinations/psychosis in addition to more typical seizures. These problems are due to temporal lobe dysfunction often related to the underlying cause of the epilepsy. First I would recommend that you get an extended EEG, such as a 2 hour sleep deprived or a 24-72 hour EEG to assess your inter-ictal activity (Spikes, etc) and evaluate you for possible seizures. I would also recommend that you switch to an extended release Tegretol(XL or CR) or Carbatrol, and split your dose to twice per day. This will keep a more constant level of drug and decrease your chance for another seizure. If this does not stop the seizures, you may need to switch to another drug such as trileptal, lamictal, keppra, topamax etc. If you fail 2-3 drugs then you may be a candidate for epilepsy surgery (Which requires a workup including MRI, Epilepsy monitoring unit stay, PET scan, neuro-psych eval, and often invasive monitoring).
The symptoms you describe are NOT consistent with CJD. Patients with CJD develop rapid onset and progressive (over 6months~2years) dementia, myoclonic jerks, and aphasia. Testing for CJD includes lumbar puncture for 14-3-3 protein, MRI Brain, EEG and possible biopsy (tonsil or muscle for vCJD, brain for other CJD).
I hope this has been helpful.
sorry, just to correct myself. i was put on tegretol for my temporal lobe epilepsy 5 years ago when it began. and i take 1200mg of tegretol a day, 600mg twice a day in the morning and at night.
