My grandma recently came out of a brain surgery.

She may be suffering from the anesthesia. As we age, its hardervfor the body to get rid of it. If she is back in the hospital thats a good thing. She could have problems with a Medication she was given.

Brain tumors can cause Migraines , falling down and also vomiting . I had One removed and Had to have My face opened and couldn't Move My head for a Month . Actually It Hurt for a year and I still had Moments of falling Down . I felt quite sick for 8 months and then slowly got Better . Hopefully she will recover But give it time - it is scary when a doctor says " You Only have 6 months to live . " So Give her sometime to heal .

Your grandmother is only 58 I see from your profile. That's so very young in this day and age. I am so sorry to hear this.
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.

A craniotomy to remove a benign brain tumor is a serious surgery that has a very long recovery period associated with it. A meningioma brain tumor removal has a very high survival rate while a glioblastoma does not. The complications with brain surgery can be quite extensive. Set your expectations for grandmas recovery accordingly. See what the prognosis is with her doctors.

Best of luck to you and to grandma.

It sounds like she has deliriums and/or hallucinations. I experienced this with my elderly family members after their surgery. It is scary and the staff will tell you it is common among elderly with surgery. If it is delirium there is really nothing that can be prescribed to eliminate. Rule out infections and have them determine if it is a reaction to narcotic pain medication.

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.

Brain surgery is scary, period, and it will take some time for her medical team to evaluate the success of her surgery and for your grandmother to recover. I'm an information junkie so if I were you I'd find out the name of her tumour and do a lot of reading.

Ask her neurologist/surgeon/doctor.

Delerium, ask her medical team about it.
