are there any longitudinal studies about constant exposure of videogames (or flashy dopamine screens in general) in early developmental years being the cause of ADD? It seems so obvious i'm surprised i haven't found a lot of literature around it.

here are 2 of my findings that seem legit to a certain extent:

>Impact of video games on plasticity of the hippocampus

>Association of Digital Media Use With Subsequent Symptoms
of Attention-Deficit/Hyperactivity Disorder Among Adolescents

i think the last one got it right, but the timespan of the study was too short to see any remarkable evidence.

contrary evidence also welcome
