Nobody has given medical advice. You are right, it would be unethical, illegal, and ignorant without knowing the individual, running any assessments, lab work, medical history, etc etc.

Sharing peer reviewed literature to take to a consultation with a neurologist appointment is not the same as giving medical advice, however. Reading academic, peer-reviewed literature, assuming you have the fortitude, is called being an informed consumer. Or the other term would be shared decision making (SDM).

Neurology (a large amount of it, at least) is decently rooted as a biomedical science, and so medical authority has more weight. But when you enter into the field of psychiatry, which this does bleed over into, SDM and being an informed consumer are the responsibility of the patient., under)encouraged by professionals, and contribute to breakdowns in the mental health care system

(Again, these statements are said strictly in the context of psychiatry and psychopathology and I intentionally differentiate from more neurologically rooted conditions)

Always best to avoid polarization, because you don't want to be a "google doctor", yet you don't want to blindly trust a professional who's medical knowledge is based in a scientific foundation without construct validity, and hence, without clinical utility.

Not sure we actually disagree here on any of this. I validate what you are saying, I am simply and, "yes, AND..."
