How to remember what you said in therapy

Why forgetting is normal

Memory for a therapy session is poor for most people, and studies have started to measure how poor. In a randomized trial of 30 adults with bipolar disorder and insomnia (Lee and Harvey, 2015), patients freely recalled what they could from the previous session each week while therapists logged the points they had made. Patients recalled between 19.6% and 36.9% of those points. This was cognitive behavioural therapy for insomnia, with a small sample, and it is a different kind of session from a psychodynamic hour. It shows the order of magnitude, not a law.

The same study found that the number of points recalled was linked to better outcomes. A second study, of 48 adults with depression (Dong and colleagues, 2017), found that recalling more of the treatment's content was linked to better adherence and, for the overall amount, to staying free of relapse. Both results are associations. Remembering may help, or people who are improving may remember more. They do not show that a better memory causes recovery, and they do not say you have failed if you forget.

A session is dense, partly emotional and often about things you would rather not hold in mind. Forgetting is what that kind of material tends to invite. The task is to make the useful part easy to recover, not to remember everything.

Four ways to keep it

Recording is the most studied. A 2009 survey at a CBT clinic where sessions are routinely recorded (72 patients at the start, 31 at the end, 15 therapists) found that most patients listened between sessions, often discussed the recordings with their therapist, and planned to keep them. Patients and therapists rated recording as acceptable and useful. Therapists were more worried than patients that listening could distress people. The study measured attitudes, not outcomes, and it was one clinic, so it is not evidence that recording improves therapy.

What is worth keeping

You do not need a transcript. Keep:

• The sentence that surprised you, in the words you remember.
• A phrase your therapist used that you did not follow.
• Any task or question left open.
• What you felt in the body when a topic came up: heat, a tight chest, a wish to leave.
• What you did not say.

Leave out the retelling of events you already know. If they mattered, they will come back.

A five-minute method

1. Before you leave the building, or the call, write one line: the most striking thing said, by either of you. Do it while you still feel it.
2. Later that day, add two more lines: what you disagreed with, and what you did not say.
3. Before the next session, read those lines once and pick one to open with.

That is all. The point is to turn a dense hour into three sentences you can find again, not to build an archive.

If you remember nothing

Some sessions leave only a mood. That is information too: a heavy or flat or restless feeling after a session says something about what was touched. Write the mood and the time of day. At the next session, say plainly, "I left last time and could not remember what we said." Therapists hear this often, and it is a usable start. You can also ask at the end of a session for a one-sentence summary of what the two of you agreed was important. Some therapists do this unprompted; others will if asked.

What the memory studies leave open

The two memory studies above used CBT, in specific conditions, with small samples. Neither tested psychodynamic sessions, where much of the work is in the feeling and the connections between topics rather than in points to remember. Neither tested whether note-taking or voice memos improve outcomes. In the searches behind this article no study was found that did. So these methods are reasonable habits, not proven treatments. If a method makes you more anxious about getting it right, drop it.

Privacy

Notes about your mental health are health information. Under the EU's General Data Protection Regulation, data concerning health is a special category of personal data (Article 9), and explicit consent is one of the grounds on which it may be processed. That rule governs companies and clinics, not your private notebook. It does show how sensitive the material is.

Some practical choices follow:

• A paper notebook has no sync, no cloud and no search. It can be lost.
• A notes app is searchable and convenient. Check whether it backs up to a cloud account and who can open that account.
• A voice memo may contain your therapist's voice. Ask before recording anything they say.
• Name notes plainly, with no full names, so a glance at the screen reveals little.
• Delete what you no longer need.

Bringing an AI reading to your psychologist

Some tools, TwentyThird among them, write a reading from what you have told them. That can work as a conversation starter: a few paragraphs you put on the table with the question, "this says I avoid conflict with authority; does that fit?" It is a hypothesis built from your words, by software. It does not know you, and it can be wrong. The person who sees you can tell you what fits and what does not.

Where TwentyThird fits

TwentyThird keeps your conversations with Oneli in written form and notes what recurs. Some members may use that as a memory aid between sessions. It is an AI, not a therapist, and does not replace the notes you keep yourself. Psychologist supervision is in early access today. Read more in how Oneli works and safety.

What this does not replace

Your own notes do not replace the conversation with your therapist, and no app or recording can tell you what a session meant. If you are in danger, contact local emergency services now. In the EU, call 112.
