I truly know how it feels to be told your loved one has a glioblastoma. My father was a very fit man for someone mid 80s, then out of the blue, he felt nausea, odd weird headache and latterly, feeling his balance was not quite right. He had a few blood tests but nothing came up, then had a few more a few weeks later, still nothing. Only when he had an MRI, did the consultant see something that 'may' be a mass. He had a lumbar puncture, showed nothing. He was already an in patient but they then referred him to a specialist neurological hospital, where they did a CT with dye. Then came the harrowing news. There was no offer of radio or chemotherapy as he was already too weak and immobile and had already lost motor skills and all use of 1 whole side of his body. He wanted his last weeks at home. He had 5. From diagnosis to death was 9 weeks. It's been so quick and shocking with a rapid decline. In his last week, I believe he also couldn't see. He had lost his speech already, it took too much effort, but he could mouth words. He slept aloft but had some lucid times too, right near to the end. He wasn't in pain which one has to be grateful for, and even in an unresponsive state, which he slipped into in his last 18 hours or so, when he heard me talk to him, he squeezed my hand. You must keep talking to your loved one, because they really do hear, right up till they pass and I believe it is a comfort for them. Personally, I think it was a good thing not to have been offered any treatment, because at it's best, 50% of patients may get 12-15 months, of which a lot of that time, they will be dealing with sickness and side effects of the treatment. It may be worthwhile if you are mobile and can get on with living inbetween treatments. Who knows. Everyone will do what's right for them. I understand the pain and shock the relatives go through on hearing their loved one has this deadly disease, and I just wish more funding was available to find a cure. I have written this as so many people have written that they don't know what to expect from this illness. Everybody is different, of course, but I thought I would share this. My thoughts are with everyone battling this awful illness and to their loved ones.
