I posted a very similar message just a couple of weeks ago and I see some familiar names on the list of responders. I want to thank them again for their input and reassurances.
I finished my radiation treatments in October. A couple of months ago I suddenly had a severe increase in head pain, pressure and seizure activity but the MRI showed no evidence of tumor growth and only minor changes in edema. My decadron dose was increased to 12 mg a day but it did not relieve my symptoms. I reached the point where I was having auras dozens of times of day and could no longer do any day to day tasks (clean house, cook, etc.) without fearing a seizure. Clonazepam was added as a supplement to Dilantin to control my seizures, which finally let me regain some minimum normalcy in my life.
I met with my neuro-oncologist on Monday and he is confident that this is a reaction to radiation necrosis. He said radiation side effects are expected for the 1st year after treatment, and he has seen necrosis develop as much as 7 years after treatment. Although my edema apparently doesn't warrant a shunt, he said that the necrotic tissue can be an irritant and sometimes it will have to be surgically removed to improve symptoms. But of course, doctors want to keep surgery as a last resort. So, I now am taking 3 anti-seizure medications: dilantin, clonazepam, and topamax in addition to decadron. I'm also going to slowly try to decrease the decadron dose (your body adjusts to the higher dose so it is a long and difficult process to get off of it).
Anyway, I don't know if any of this information is helpful for your mother's situation. I mainly wrote to let you know that she is not alone with the seemingly sudden setback. I've only been on the new meds for a few days and I'm doing well. I'm back to doing things around the house, running errands with my husband (obviously I still can't drive), and even ate at a crowded restaurant, which is something that I haven't done since I was diagnosed last July. Hang in there. I'm trying to learn not to assume the worst every time I have an apparent set back. It is a roller coaster.
Best wishes to you and your mother,
Sharon
