The project

The project

Welcome to

ADxS, the name of this project, is a term of art and stands for ADHD as the totality of all forms of presentation (subtypes) (ADHD-HI, ADHD-C, ADHD-I). Since March 13, 2023, we have been using the term ADHD for the entirety of the presentation forms of ADHD. The term AD(H)S that we used previously was first used by Heinemann and Hopf 1 aims to provide a systematic presentation of the medical and neurobiological relationships relevant to the understanding of ADHD.

To our knowledge, the complexes “ADHD and stress” and “ADHD and the immune system” were first presented in this depth by endeavors to always integrate new research approaches, whereby the advantage of topicality naturally goes hand in hand with greater uncertainty regarding the reliability of the results
Until fall 2020, there were still individual pages that did not meet the requirements for scientific presentation. We hope that will meet scientific standards throughout 2021.

A summary of the content of the entire project can be found at Summary from

The Table of contents Lists all pages (sitemap) and corresponds to the menu structure.

Naturally, not all presentations are equally interesting for all readers.
As a work in progress, the project also contains a great deal of detailed information that has not yet led to a conclusion. As is usual in scientific evaluation work, the conclusions only take shape some time after the details have been processed.

In view of the scope of the project and the complexity of the topic, it can be assumed that, despite all efforts, some misunderstandings and errors have slipped through the net
Constructive references to scientific evidence in order to correct any misconceptions and to improve and supplement the explanations and their accuracy are always welcome. has been supported by the non-profit association ADxS e. V. since 01.06.2021.

The concept of is a completely non-commercial project.

The declared aim is to deal with ADHD from a scientific point of view, while at the same time keeping all topics readable for people with ADHD who are interested in the subject. For this reason, technical terms are replaced by colloquial terms or explained using mouseover text. Introductory texts should also remain understandable for beginners.

Our own opinions and hypotheses are always identified as such.

As a rule, all facts are linked to directly verifiable sources. In the age of fake news, the verifiability of facts is of particular importance.

For many topics there are (usually indented) in-depth explanations, including (often as fold-out texts) scientific data, facts and explanations. Occasionally there are links to quite general sources that explain the background for people with ADHD or non-experts in a generally understandable way.

The aim is to enable people with ADHD and doctors, for example, to exchange information on certain aspects using a jointly accessible source.

The goals of

The aim is

  • An expansion of the scientific / technical advisory board
  • An opening for specialist contributions from other authors
  • An openness to the presentation of dissenting opinions by specialist authors, which are identified and justified as such
  • The inclusion of a large number of perception reports from people with ADHD. explicitly does not want to follow the concept that a contribution/chapter must come from a single author or a closed group of authors. We believe that it promotes discussion and knowledge discovery when contributions to the discussion, additions (even just a few sentences), or even longer texts within a contribution are added by other authors (with attribution). is looking forward to

  • Technical presentations and contributions to the discussion by scientists, doctors and therapists
  • Case studies from the perspective of people with ADHD
  • Notes, suggestions for improvement and additions
  • Other opinions with a professional justification

Publication status

It is intended to make the texts of this project citable at regular intervals through fixed print runs.

Since freely accessible publication on the Internet is not otherwise possible, this work will not be published by a specialist publisher. In order to remain citable, a printed edition will be published from time to time.

The 1st edition of this project as of April 2019 has been published in print by MuR under ISBN 978-939384-99-1: The AD(H)S Compendium - AD(H)S as a stress regulation disorder. In the automotive industry, there is the pre-series or zero series. From this point of view, this would be the correct term for the then status of in the form of the 1st edition (April 2019).
