Memory retrieval, not storage, hinders mouse models of Alzheimer’s

I found this report on a research project very interesting:

All the usual caveats apply, of course  -  many years before this knowledge could lead to a treatment, probably doesn't apply to all dementia, etc. But I've always felt that S's most significant problem as the dementia progressed was retrieval of memories rather than storage. I felt many times that the memory was still in there somewhere and occasionally its retrieval could be 'triggered' by an event, what someone else said, a picture, music.....
