Executive disorders diagnosed by psychiatry are just caused by agency of individual being over-ruled by an external agency, using monopoly on violence. The diagnoses are just a religious myth, to legitmize the subordination of humans who have not given consent. So just a myth, like "witches", witches only exist in the mind of a believer, so do "hysteric" people or "autistic" people only exist in minds of statists. It's local myths in local cults, and will be outdated in the networked, digital society that is being developed on top of the internet.
