I would look into two things...the first being the side effects of Depakote. You should ask your doctor about lowering the dose to see if the symptoms change.
Secondly, I would pursue neurological tests if your doctor thought the symptoms you had were consistent with anatomical pathways, and a possible neurological lesion. If not, I would recommend that you have a neurological examination to free yourself from doubt, but don't have additional tests unless there is a strong indication to do so.
Thankyou again.
