What's wrong with my mom?

My mom goes through these episodes. She rocks back and forth, she may try to hold a specific position (this time she had her thumb over her middle finger on both hands and were moving them back and forth). She alternates between fear in her eyes and a blankness. Sometimes telling her it’ll be alright helps her calm a bit, or just cry. She sobs, too. If she starts talking it doesn’t make sense – I was trying to talk soothing words to her, and she stumbled over her words and repeated herself, but did said she’d call me back in 25 – 30 minutes. She tried to say the same thing a few times during the episode. She also would repeat us, saying it was okay. Then sometimes she’d say, “Seriously?” “Really?” “Oh my God!” She repeated no a few times too. She doesn’t fully comprehend things and can’t seem to hold on to thoughts. She’s sweating quite a bit too. I’m not very familiar with her episodes so I can’t give a good list of symptoms. I’ve seen another where she fell but caught herself and was on her hands and knees on the floor. She was shaking and her elbows would give out and then hold her back up over and over. She either couldn’t hear us or couldn’t respond.

Apparently she’s gone to the doctor and the doctor said they were panic attacks. It seems she doesn’t seem to remember them very well though. She has issues with her blood sugar dropping and I don’t know if that could be some of it.

I first got on WebMD, but I have no idea how to look up these symptoms. Thoughts?
