confusion, incontinence, steroid myopathy

[nvsavin]

Can someone please offer any input into my mother's condition. Trying to make a long story short: liver mets in 2002--cleared by Herceptin. Body remains NED. In Jan. 2005, brain mets. 6 lesions treated with WBR and then gamma knife. Was doing beautifully until Jan. 2006 when one lesion appeared to be growing. Neurosurgeon believed it to be necrosis. Continued to grow until finally, one month ago, it started to shrink, just as the neurosurgeon expected--that was the nature of necrosis. He stated my mom was "finally over the hump." But then, right after that MRI in early august, she barely could walk, she suffers from periodic incontinence and is very confused. She was admitted to the hospital. They repeated the brain MRI which was fine and did a bone scan which was clean. About 3 months earlier she started decadron again. The oncologist suspected the decadron was too much for her causing her steroid myopathy which is why she can't walk. But what about the incontinence and the sudden extreme confusion? Has this happened to anyone? Any input? Thanks to all.
