Severly deficient autobiographical memory, I can only retain factual information, no lived through experiences. Though what facts get saved and what i can recall at any given moment is completely randomized and out of my control by the ADHD side.
So there's basically no functional or reliable memory to speak of.
I am almost the embodiment of "living in the moment" because for me there actually doesn't exist anything else, as soon thinking part of my brain shuts down or is inhibited by some drug.
It has taken me years to implement additional layer of thinking to take past and the future into consideration as something real.
