My mom passed in march but fought giloblastoma for a year she had swelling and that would mess with her cognitive skills so they would do a round of steroids and she would get better then few weeks we notice her speech wasn’t too good and she wasn’t able to walk as good so they would do another round and that went on for 8 months at the end she had to stay on them cause she had swelling which is the reason they said she wasn’t talking well she had stopped talking completely at the end . My prayers and my heart go out to anyone who has a loved one that they. Are caring for with giloblastoma god be with you all
