I am just one bit of anecdotal evidence, but this was the case for me as child. However, it is still the case for me as an adult too...
Video games and information about whatever is piquing my interest at the time have always been my addictions[1]. Video games have always been my escape, while subjects I am interested in just typically trigger hyperfocus.
Other than the "escape" video games provide, there is also a strong correlation between desired outcomes and effort. Much unlike real life where hard work is rarely rewarded and typically taken advantage of. I have always felt like I have had to put a lot of effort into things just to function "normally," and I do not have the make-up to excel in anything.
I know I have, and probably still do, waste a lot of time with video games and media (I should be working right now), but in some dark way it's one of the few areas in life where I feel like I can actually be halfway decent at something.
I've been a professional software engineer for almost 6 years, and I still feel like most junior devs and fresh grads could spin circles around me. I try to improve, I put in hardwork, but I have nothing to show for it.
I treat my condition(s), but at the end of the day I feel like I am just living the story of "Flowers for Algernon."
[1] I do not mean addictions as defined by medical terminology, but in a more commonly used manner.
