seizures
"I was prescribed this medicine back in the late 80's for seizure control. I recently stopped using this in 2010. 
It controlled my seizures well, but I did not realize the side effects of it.  
Side effects were irritability, anger, increased depression and behavior.
Because I literally grew UP with this medicine, I can now see these issues after changing the medicine. My brain was built to use it during puberty/young adult.

This does control seizures, and actually suppressed anxiety by slowing down all brain functions. 

Be aware that epilepsy is cor-morbid with depression quite often and this medicine may enhance/increase depression symptoms."
