One other problem I have had for some years now is that I can’t visualise. By this I mean I can’t see or picture things in my “mind’s eye”. Whenever I talk of this, the other person finds it hard to understand (or believe). If I say that it also affects my memory, things get more interesting. Because I have very poor episodic memory – memory of life events. This is most true for visual memory. I’ve been asked questions like “how do you get around your home?” As if somehow I may be blind! More reasonably, I’ve been asked how I remember where something is in my home. To be honest, I’m not sure – but I usually do! I think I compensate with a kind of physical memory – a memory of how to move around to find something.

One thing I dread is if someone in a car asks me for directions. Because I can’t visualise the route, I’m worried about missing out a turn or landmark. In fact, I’m sure I have. Again, I have to try to feel my way around the directions.

As with persistent migraine aura (PMA) and visual snow (VS), medical science seems to poorly understand all this. I’ve only found one study on the variation in visualisation. I’ve found nothing at all on what I call persistent episodic visual amnesia (PEVA). Now, I’m not suggesting PEVA relates to PMA or VS. I’ve no evidence for this (or against). But I do know one other person personally who says they have the same disability in visualisation and episodic memory. But I’ve only read one post on the Internet from a stranger who clearly has the same problem.
