Hello. My partner was diagnosed with a glioblastoma multiforma stage 4 on New years eve. He is 56, and the prognosis isn't good. He has had chemo and radiotherapy and some immunotherapy. He has felt so ill, and has lost alot of weight. He has now finished treatment and is starting to feel better, but seems very different - sometimes agitated, sometimes aggressive, very not himself. Has anyone else had an experience like this?
