We Have A Lady We Take Care Of And She

We have a lady we take care of and she is 72 years old. In November last year she had a stroke and seizure unsure which came on first. Within 5days she made almost a complete recovery. This January she had another while we were in another state. She was intubated for 3 days so that they could do an mri. She is developmentally delayed so she can not express symptoms very well. She was put on dylantin at first and then parietal was introduce. They lower dylantin as they increased the lamictal. She seems to go through these faces of confusion, and seems to be having problem with her site especially her perifial vision on her left side. Can this be caused by the seizure or possibly the medication. This has been going on since the seizure in January.
