You know the name for it now.

There is no diagnosis to receive, exactly. Neither aphantasia nor SDAM is in the DSM or the ICD; neither has a UK clinical pathway; neither needs treating. What you have just had is a naming, which is quieter than a diagnosis and arguably more useful. Until the word existed, the experience did not either — not in any way you could describe to a partner, a GP, or yourself.

The first few days

Most people go through a version of the same arc: relief (“so there is a name for this”), recognition (“so that is why that thing I always found strange made sense the way it did”), and a surprising amount of grief. The grief is worth saying aloud. Realising that everyone else has been carrying their people around as pictures all their lives — while you have been carrying them as facts — lands in the body. Give it space.

Things that may start to make sense

• Why you write everything down and always have.
• Why meditation, guided visualisation, and “imagine a place you feel safe” exercises have always felt like being asked to do something in a foreign language.
• Why you do not miss people the way they seem to miss you.
• Why looking at an old photo feels new rather than familiar.
• Why your partner sometimes seems hurt by something you did not mean as coldness.

None of this is a character flaw. None of it needs correcting. The brain you have always had is the brain you have now; the only thing that has changed is your language for it.

What to do next, in roughly this order

1. Read the guide. The cornerstone guide is the backbone of this site — written to sit alongside you for a while, not to be rushed. It is cited throughout so you can follow anything that matters to you back to the research.
2. Take the questionnaires, if you have not already. The VVIQ for aphantasia, the SAM for SDAM. They do not diagnose; they tell you where on the spectrum you sit. Both are free and take ten minutes. See the resources page.
3. Talk to one person in your life — a partner, a friend, a sibling. Not to explain the whole thing; to say “I just learned there is a word for this and I am still working out what it means”. The telling matters.
4. Mark the forum for when it opens later in 2026. The newsletter below will tell you when; the forum page also has a sign-up for earlier seed invitations.
5. Subscribe to the newsletter if you want the research delivered in plain English once a month. That is it. No other emails.

What you do not need to do

• You do not need a GP referral. There is nothing clinical to refer.
• You do not need to “work on” mental imagery. Nothing has been shown to reliably produce it in someone who lacks it, and the apps and programmes that claim otherwise have no evidence behind them. See the guide, section 5.
• You do not need to tell everyone. It is not a diagnosis; you are under no obligation to disclose it. Many people find it useful to tell a partner and a couple of close friends and leave it there.
