Maybe you should stop commenting until you educate yourself. Have a talk to some of your providers. Read a few peer review journals. I am married to a neurologists who with his colleagues have spent over 20 years researching ADHD. There are clear differences between psych disorders and neurological. Neurological disorders like Parkinson’s disease, Huntington’s disease, epilepsy, multiple sclerosis, and Alzheimer’s disease can be clustered together because they all involve malfunction of or damage to the nervous system — the brain, spinal cord, and nerves. Nervous system infections are also treated by neurologists. The hallmarks of psychiatric disorders, on the other hand, are disturbed behavior and emotional state. Read the clinical paper The neurobiological basis of ADHD by Paolo Curatolo,et al. That should be a good place to start. As mentioned in the respected journal;
"Recently, neuroimaging has led to several important advances in the understanding of the neurobiology underlying the clinical picture of ADHD, and demonstrates a clear brain basis to the disorder in regions involved in attention, and executive and inhibitory control [1. Furthermore, transcranial magnetic stimulation (TMS) has provided evidence that intracortical inhibition, as indexed by the immature ipsilateral motor cortex, normalises with psychostimulant treatment. There is an exciting confluence between emerging studies in basic neurobiology and the genetic, neuroimaging, and neuropsychological analyses of ADHD. Knowledge of neurobiology can offer child neurologists, psychiatrists and other healthcare professionals a valuable framework for the interpretation of clinical findings of children meeting the criteria for diagnosis of ADHD. In this article we provide a brief overview of the salient neurological basis of the disorder."
Furthermore, in another well published study done at MIT, unlike other psych disorders, the brain in those with ADHD showed up differently in a MRI. Further suggesting that it is a true neurological disorder well beyond dopamine.
I am not saying you don't know what you are inexperienced, I am just saying your experience is shit. Try picking up a journal that wasn't fed to you by the company once in awhile.
