My sibling was diagnosed with a grade 4 gloiblastoma, which is inoperable. She is getting progressively worse. The most upsettjng symptom is her aggression. It upsets everyone near her although we know it's the tumour. We miss her personality. How do we deal with this on a daily basis? Is there anything than can help? Some of the stuff she says when she's aggressive make us anxious in case we dont do everything we can for her. Any advice by experienced nurses would be appreciated.
