Sadly, and I am not a health expert, not a physician, but it does sound to me like a TIA. About all you can do for now is to read up on TIAs, what if any treatment can be undertaken, including prophylaxis, which is almost always a DOAC (Direct-acting Oral Anti-coagulant), and what she (and you) can/should do in order to stem their onset in the future.
These signs are often an indication of systemic inflammation. The adhesion of plaque and thrombosis are both exacerbated by inflamed tissues, including portions of the vascular system. Your physician and perhaps a neurologist will know where to take this from here.
