Did they do a tilt table study with his cardiac consult? My son has neurocardiogenic syncope, and it can cause anoxic seizures, or seizure like movements, most people just faint and then they began to recover. He has to drink 4 quarts of water a day and is on special meds too. The tilt table test produce the same vasodialation that is happening when a person faints....check it out....
Depakote is used to help seizures not make them worse.
Some seizures start out one way and then they change and get worse.And they needed to change the medicine he is on or add to the depakote.
I am so sorry you son is going threw this and your family also.
can you tell us anything else about your son,like has he been on any other medicines in the past? Dose he have other things going on with him along with the seizures.
I know this is scary and wish that know one else would ever have to go threw this.My son has seizures and has been on depakote since 2006 and we have tried 6 other medicines to try and stop the seizures.They think my son has lennox gastro syndrome.
god bless you and your family.
