@sonya_nc, I can imagine that this is worrisome and it can be confusing to know what questions to ask medical professionals to be proactive and get the care your mom may need. @musicflowers4u may have some experience to add.
Here's an excerpt from the article:
"You may have more than one TIA, and the recurrent signs and symptoms may be similar or different depending on which area of the brain is involved. Since TIAs most often occur hours or days before a stroke, seeking medical attention emergently following a possible TIA is essential. Seek immediate medical attention if you suspect you've had a transient ischemic attack. Prompt evaluation and identification of potentially treatable conditions may help you prevent a stroke."
