@Birdofparadise8 umm... I mean I don't know the science of it, but it's to do with deficits in working memory, one of the facets of our executive functions - which are moderately to severely impaired for ADHDers.
In other words, I struggle to hold information in my mind, which makes it much harder to remember things, and much harder to convert things to long-term memory. For example, I might be midway through a task, go into another room for some reason, and forget that I was working on said task. Or I will lose track of items, even if I was just holding it a minute ago. If someone tells me a piece on info like an address or a date for an event, if I don't write it down immediately I will forget within like 20 seconds.
