I have browsed through this forum and, to my relief, seen that many other people are going through the same thing as me and my family.
These questions have all been asked before, but it would give me such relief to hear from other people - because this experience has been hell.
I am in college, early-20's, and my father was diagnosed with GBM on August 13th, 2012. His speech became slurred about three weeks before diagnosis, and that was the impetus for the first MRI. His situation was particularly complicated because he had two tumors - one inoperable tumor at the base of his brain, and another in the upper left side of his head. He underwent debulking surgery, typical temodar/radiation therapy, and we have been giving him a THC tincture as I read it can be beneficial for GBM patients.
Despite all our efforts (My mother and sister are very involved as well) his MRI two months later showed progression, and quickly after his symptoms began to become markedly worse.
Now he can barely speak because his words are so mumbled and slurred, he is basically paralyzed on the right side of his body, so he is confined to a walker - even though he clearly needs a wheelchair at this point because he can barely manage to walk across the kitchen.
Worst of all are the cognitive declines. His speech has been a serious issue since the beginning, but now it is clear he isn't fully "there." He demands unusual things at all hours of the night (eg. "I..W...aannt...appuull pie!! at 2am in the morning), gets angry and yells obscenities more than a dozen times each hour, and shows absolutely no appreciation for the unbelievable effort my family has put in him. Even worse, he ran three family businesses solely by himself, and we all now have to learn quickly how to take over the companies, learn state and federal business taxes, acquire real estate licenses, learn everything about the companies. That, in itself, is a 100 hour a week job for all of us, on top of the fact that my dad requires 24-hour care. He is also awake every night because he has to pee every 45min, and now has to wear a depends diaper because he has accidents every night.
We just started Avastin, which we are very optimistic about, but it appears he may be allergic to it.
I just want to know if a GBM patient can ever recover their cognitive abilities once they are gone. I have accepted that he will die, and am prepared for it, but the worst part is dealing with this shell of a man who is no longer my father.
All I want is one hour, or even one minute of lucidity so I can say goodbye to him properly.
