so she has been seeing things, and saying "get out of my head!" to nothing, and said earlier "something's trying to get in my head." She's back in the hospital. I'm scared. she got some of a "benighn" tumor removed. I don't know what's going on. Answer in comments if you do plz.
That the tumor is benign is good news, but even with a benign tumor areas pressured by growth of abnormal cells will affect the brain.
The good news is that you have a diagnosis and a treatment (the surgery) has been done. I encourage you to speak with whomever is next of kin here and has been given the details of the surgery, and the prognosis (what the surgeon believes was the case with this tumor, what areas of the brain the tumor may have affected, what recovery of that area of the brain is expected).
As Lea told you, this may be a very long road. There will be rehabilitation. There will be deficits. And added to this there may be some delirium caused by just the hospitalization. As a nurse I can assure you that almost no patient can remember a single day of his/her time in intensive care units. They have a kind of (blessed) amnesia about it all.
Take this a day at a time. Know that what you are seeing now isn't really the grandmother you know, but someone whose brain has been changed by a growth that occurred, someone who may not fully ever be "back to normal". The good news is that there's lots of plasticity and lots of accommodation in our old brains; they can adapt and adjust over time.
So again. A day at a time, and I wish her a good recovery, and you patience and love to see it through. Best of luck to you.
Best of luck to you and to grandma.
My uncle recently experienced deliriums and hallucinations. They were very intense and concerning. It took months of intermittent deliriums and three hospital stays to get an infection under control.
Good luck! It is scary but in many cases it does resolve itself.
