To be cautious, one should not take high confidence as any absolute guarantee of anything. - Elizabeth Loftus

I collaborated on a brain imaging study in 2010, and the overwhelming conclusion we reached is that the neural patterns were very similar for true and false memories. We are a long way away from being able to look at somebody's brain activity and reliably classify an authentic memory versus one that arose through some other process.

Even if it's going to be a harmful memory, they don't want to let it go. (This is) why sometimes I get such resistance to the work I do. Because it's telling people that your mind might be full of much more fiction than you realize. And people don't like that.

It is possible not to think about something for a long time, even something unpleasant that happened to you. But what's been claimed in these repressed-memory cases is something, by definition, that's too extreme to be explained by ordinary forgetting and remembering. They're saying that in order to go on in life, you had to wall off this memory, because it would be too painful to live with. Then finally you go into therapy and crack through the repression barrier and out comes this pristine memory. But there really is no credible scientific support for that notion.
