Hi, I'm A 46 Y/o Female With Afib. I've Had

Hi,
I'm a 46 y/o female with Afib. I've had a suspected TIA about a year ago. Medications and cardioversion have not helped and my doctor has recommended ablation. The trouble I'm having is that ever since the TIA, I've had daily bouts of articulation and slurred speech issues. I also have a lot of trouble with my eyes and they seem to 'float' so I get dizzy. I've had an MRI to rule out MS and stroke and an eye exam, but no one can determine what is causing these symptoms.
