This intrigued me, so I looked it up.

I am a rapid cycling bipolar, which they say is a person having four or more mood episodes in a year.

From what I looked up, it looks like Ultradian cycling is having more than four in a year, and describes that they can occur in week intervals or even all in one day.

Here is a site I saw:

About the liver enzymes-it appears that anti seizure medications can cause liver enzyme elevation-not sure on this, maybe some one else can add to this, but it looks like they check it early on, to see if it affects you to be on the safe side. If you have an insert on side effects of the depakote, I would check that to see posible side effects, maybe it would explain it???

I know when I took lithium, I had to have interval blood tests to check for kidney function.
