my wife is a brain tumor survivor with no surgery, just radiation and chemo. in 1998. she is now struggling with memory loss tremors, walking vision etc. she is now age 65. her doctor has her on25mg toprol, 40mg simvastatin, 25mg levothyroxin,and 2.5mg ambeim. her neurologist has her on depakote er 500mg once per day and 10mg namenta twice per day. seems to me that the side effects of most of the doctor's meds. could possibly causing her problems or contributing to them, i would like to try taking her off all but the depakote and namenda and see if she has improvement. what do you think? thanks, chuck
