Headaches and Scrolling Vision

There has been an unfortunate increase in these episodes of headaches and scrolling vision.  She is tearful and frustrated because of how much they have been interfering with her school life recently.  She was diagnosed with hypothyroidism a few months ago and we have had to make some adjustments after the addition of the synthroid.   We first had to increase the Lamictal by 25 mgs for some mania but this may have precipitated the headaches. So we go back to the doc as soon as possible so we can come up with a solution.  Maybe we need to get her into a neurologist.
