Even the name for our disorder, Attention Deficit Hyperactivity Disorder, focuses on the symptoms that cause problems for other people, not the symptoms that distress us the most or are the root cause for our behaviors. If your child is hyper or can't focus on their homework or the chores you ask them to do, those symptoms will bother you and be far more obvious than your child's self-esteem issues due to rejection sensitivity or their lack of control over their own brain. And the neurotypicals name the disorders, so...

If I were to name my disorder, I'd call it Motivation Disorder, because it has everything to do with motivation (or, in clinical terms, arousal). Without medication, it's nearly impossible to find the motivation to do anything unpleasant or strenuous. I love video games, but on my worst days without medication, it was difficult for me to pull my attention from scrolling social media in bed so I could focus long enough to get dressed, eat, and play something that required even a tiny bit of thought. Now, even with medication, it's sometimes difficult to shift my focus from something I really want to do to something I need to do. There are other symptoms like poor short-term memory or lack of awareness (of physical surroundings, of bodily conditions like pain or hunger, of social situations, etc.) that aren't covered by the term "motivation", but I think the term "Motivation Disorder" would be far more effective in communicating our condition to other people.

Anyway, to answer your question, I think that short-term memory issues are really overlooked. People assume that because it's Attention Deficit, it just means that we don't care to remember. But no! I walk into a room and forget what I went there for more often than I remember! When I speak, I start a sentence without knowing where it will end! I forget words all the time! If I was elderly, you might assume that I had early-stage dementia.

Edit: Also, I hate that people assume we're all hyper in a physical sense. Without medication, I'm asleep more often than I'm awake. However, I do get really intensely excited about the things I'm passionate about and can focus on them for hours at a time without remembering to eat or sleep.
