Storming?

Hi there,
My sister had a brain aneurysm that burst October 22, 2018
She had a 20% chance of making it through the surgery. She made it. Now the long road to recovery and our new normal. We have had some great move forward but we’ve also had some setbacks. A couple months back she needed to have a brain shunt inserted as well as a baclofen pump for her spasticity. Most recently she has been experiencing Something called “Storming”.
This is the first I have heard of this term being used since her surgery. I was wondering if anybody else has heard this or was told about this during their aneurysm?
Anything would help.

I had never heard of it. Took me a bit but I found this https://www.ncbi.nlm.nih.gov/pubmed/14998101

Best to ask the person that provided the definition. I’m never afraid to ask a medical professional to “dumb it down” for me. I figure what good is it, if I don’t understand.
