I thought I'd update:
We went to the Dr. For Patrick's issues today. The Dr. Suggested several tests, starting with the least expensive/less serious.
First: we test for B12/thiamin and one other thing to see of those levels are off. $120?
Second, getting an ultrasound on his carotid arteries. Probably around $150-200 if it's the same a Abyni's U/s we got for her kidney stones.
If neither of those show anything, then it's an MRI to check for evidence of a stroke or potential stroke/TIA. $500ish through them. (Or the possibility that he's already HAD a small stroke that we missed)
He is also changing him from his current anti depressant to a different type in case that's making things worse.
So... That's where we stand at there's moment. And we need to get baby aspirin for him to take to help with the possibility of stroke issues.
