Anyone else have herceptin brain?

[Christine MH-UK]

I am on herceptin, but I started late because I couldn't get it until after ASCO last year. In fact, I started so late that I had largely recovered from chemo brain.

However, now I wonder if I am coming down with herceptin brain (is there such a thing?). I keep on forgetting things and my memory is getting worse. I am 40, so I don't think it's Alzheimer's. I was talking to a friend this evening about how I had a parsley plant for her that I was growing in a plastic milk bottle and I couldn't for the life of me remember the word milk bottle. It does seem to be getting worse as the treatment goes on. Having said that, I do routinely give one-hour presentations, so my memory isn't completely shot, but I can tell that my brain is somewhat fuzzy.

I have looked on the drug information and all I can find is 'abnormal thoughts,' which I think means psychosis, not having a memory like a seive. Anyone have any ideas?
