Her problem started last summer. She still does normal household activities well, and her memory isn't much worse than a normal 64 year old. The problem is she see's extra dogs that magically appear & disappear. And her deceased Mom & Dad visit all the time. That's it. We went to her Gp she did a CT scan & a couple of blood tests. She referred us to a Neauroglist. He talked to her for just 10 minutes and ordered a battery of test including an MRI saying the ct scan was useless. Why can't doctors try meds instead of wasting time & money on useless tests?
