I don’t have episodic memory. AMA
I mean that quite literally, although there’s some nuance.
Three years ago, I suffered a severe traumatic brain injury. I was unconscious for a long time and went through extensive rehabilitation. One lasting effect is that my episodic memory is severely impaired and fragmented.
Semantic memory is knowing facts: someone’s name, that an event happened, or that something is part of your life.
Episodic memory is remembering a personal experience as something you lived through: mentally returning to a specific moment, remembering where you were, what you saw, who was there, or how you felt. It includes the sense of: “I was there. This happened to me.”
I can still learn facts about my life, but I often can’t remember actually being there. I may know what happened through other people, photos, messages, documents, or places I’ve visited.
I don’t replay my past as a series of scenes. I reconstruct it. Sometimes I have brief fragments — an image, sensation, or emotion — but usually not a complete experience I can mentally return to.
My neurologist explained that this is a consequence of my brain injury.
It creates a strange relationship with my own life: I know many things happened, but knowing something happened and remembering it are very different experiences.
In a way, I have a biography I can’t fully remember living.
Are you curious about anything?
