I’ve been describing ADHD for some time as “growing up American.” Could we not postulate it as a learned addiction to distraction? That it is a symptom of dopamine dystegulation caused by what amounts to dysfunctional culture, as characterized by endless and pointless novelty?
Remember: addiction to novelty causes decreased capacity for abstract reasoning, decreased social connnection, and muted impulse control. This is, in my understanding, orthodox neuroscience as it exists at present.
