Hello my dad is 89 and was diagnosed 24th September 2019 with grade 4 glioblastoma  after having a siezure.  They cannot operate and have advised palliative care only.  He has been on anti siezure meds and steroids and doing well ie still walking  and totally self sufficient.  He had a huge siezure on 27th dec and was put on end of life palliative sedation , we were  told he had hours to days to live . However after 3 days he was still with us . The drs lowered the sedation slightly and moved him to a hospice.  He has slowly come round more over the last few days and to a stage where with a nurse helping  he was eating and drinking today . Which is great . However  time frame wise we have no idea.  He was originally given 3-6 months with no treatment.  The tumour is in the middle of his head and about 4 cm big .we dont know if he can still walk at all thr physios may see him next week to assess him. His shots term memory is also really bad since this siezure.  He is more asleep than awake but everytime he wakes up he is asking , where he is, is this a hospital,  what's wrong with him, is he dying etc.  We think when he wakes up after a nap he thinks its a new  day. Does anyone have experience  of  his and know how long he may have left etc
