Thanks.

Actually there's a small ray of hope right now. It seems that the person does much better after receiving a B-12 vitamin injection. Upon doing further research, B12 deficiency is often mis-diagnosed as alzheimer's or dementia. Finger's crossed! They're going to bring this to the attention of the person's doctors.

Thanks again for the info.
