In 1998 my husband underwent whole brain radiation for treatment of brain tumor with dx of stage iv melanoma (no primary was ever found). About 5 years ago he began to exhibit behavior changes which have gotten worse since then. He is delusional, on disability and is taking Zyprexa, Amantadine, Namenda, Cymbalta and excelon patch. Still, he seems to worsen. He now has symptoms of Parkinsons with balance issues. He is 55 years old - much to young to be this dibilitated. He was tremendously active, a college graduate who owned his own business. I just cannot accept that after beating all the odds and surviving we are now dealing with this. Do you have any suggestions?
