thank you for sharing your problem with health care magic.
I advice you first of all your kid to effect a MRI
of the brain to see the condition and evolution of the diseases cisterna magna. If the evolution is negative (agavation of the diseases, comparing with previous MRI) I strongly suggest you to see a neurosurgurist.
What you must do now is to stop the seizures by using in urgency Rivotril
or Valproic Acid
in i.v perfusion and you can restart tegretol
and levipil. Tou should discuss angain with your doctor the doses.
I suggest that those medicins are use for a minimun of 5 years from the last seizure.
I also suggest that your kid effects each 6 months a MRI of the brain and a EEG to see the evolution of it's disease.
