Will I forget what happened? What ART changes about a memory

No. Accelerated Resolution Therapy (ART) does not erase memories, and you do not forget what happened. The protocol is designed to replace the distressing images linked to a memory, “but not narrative memory,” in the words of the researchers who studied it (Kip et al. 2012). You still know the facts. What can change is how much the memory hurts to bring up, and which pictures come with it.

The worry usually comes from how ART is sometimes marketed. Phrases like “erases trauma” turn up online. They are not what the research describes, and they are not what I tell people.

What stays the same

• The story. You can still say what happened, in order, if you choose to. The developer’s own site puts it this way: “The memory story remains while the images from the trauma are erased or replaced.”
• Your knowledge of the original scene. In one study, a scene was counted as treated when only the replacement image could be brought up, “although knowledge of the original scene remained in memory” (Kip et al. 2014).
• The meaning it has in your life. ART does not tell you how to feel about what happened, and it does not ask you to decide it was not important.

What can change

• The physical charge. The eye-movement sets are aimed at reducing the anxiety and body sensations, such as a racing heart, tight chest or nausea, that come with deliberately recalling the memory.
• The images. Through Voluntary Image Replacement, the distressing pictures are replaced by ones you choose. When the memory comes up, the new images are the ones your mind tends to go to.
• How distressing it feels to recall. Sessions start with a distress rating on a 10-point scale, which gives a baseline to compare against.

The VA’s National Center for PTSD describes ART as a therapy that “helps patients to reconsolidate traumatic event memories as less emotionally intense memories” (VA PTSD decision aid). That is a fair plain-language summary of the aim. The same VA page lists ART under “not enough evidence,” meaning there is not yet enough research to know how well it works for PTSD.

People often put it as the difference between remembering something and reliving it. That describes the goal, not a guaranteed result. Outcomes vary from person to person, and some people find the change partial rather than complete.

Why “erase” keeps coming up

Part of the confusion is wording. The developer’s website says the images “are erased or replaced.” Read quickly, that sounds like memory deletion. Read alongside the research papers, it is about the images losing their hold, not about the event disappearing from your mind.

Another reason is that the protocol aims for a point where the original picture is harder to call up than the new one. That is the point of the replacement step. It is not the same as not knowing what happened, and the published protocol explicitly keeps the narrative memory intact.

What about unpleasant effects?

ART can stir things up for a while. In the 2013 randomized trial, a few participants reported feeling mildly depressed after a session (which resolved before the next one), disturbed sleep, increased anxiety, or more frequent nightmares. The trial authors described treatment-related adverse events as “rare and not serious” (Kip et al. 2013; summarized in Storey et al. 2024).

If something feels off after a session, tell your clinician. The VA/DoD guideline, writing about trauma-focused therapies, notes that symptoms can increase during trauma processing, and that these increases are “typically transitory and not severe.” It should be talked about, not pushed through alone. The page on your first session covers what to do that evening.

If you are involved in a legal case

If you are, or might become, a witness or party in a legal case connected to what happened, raise it before you start any trauma therapy, with your attorney as well as your clinician. None of the published ART studies reviewed for this library examined memory accuracy or testimony, so there is no ART-specific research to point to either way.

That is not a reason to avoid treatment. It is a reason to make the decision with the people who understand your case, rather than finding out afterward that it mattered.

If you would like to talk about whether ART makes sense for a particular memory, get started.
