Speech deteriorated

Hi, I'm wondering if anyone can give me any words of advice. My grandma had a stroke a week and a half ago, it was a small stroke and small bleed on the brain. Her speech seems to have deteriorated the last few days. Muddled words or seem to be babble. I can't work our what she's saying. Is this normal, I just don't know what to expect. She's so independent and it's heartbreaking to see her like this.
