I am sorry to say it, but it is this page that has a serious development disorder.

When I look it over, I try to image what kind of user may want the information in these pages. Is it children, adolescents, doctors, people with ADHD, their families or just some "average" user? Who are we writing for?

I see obsolete facts and bad structure, e.g at the very start: Having an opening statement like "It affects about 3 to 5% of children" is close to 50% truth - ahem. This is not a childhood only disorder. Sure, that fact has a reference, but sorry, wrong context. I suspect the author at that point had no concept of adult ADHD. When someone had, a separate article was created - huh??. I guess it's merge time. Or maybe some of you, here, still believe that this is a childhood only disorder? What are we gonna do - throw references at each other?

Another example is the scattered classification information: A standard infobox with classfication, a classification section that contains generic ADHD info (except the rather surprising information that ADHD appear to be associated with antisocial disorder). This section manages within a few lines to call ADHD a 'developmental disorder', a 'behavior disorder', a 'disruptive behaviour disorder' and then the infamous association with psychopaths. All this without in any sense relating to the reader what the similarities or differences may be. Further classification information appear in various other sections below this. Now, really, is this just lack of structure or is it just really bad qualty?

Comments, anyone?

True, but for none of the neuropsychological disorders exists a single test that can either prove or disprove its presence: Anxiety, Depression, Stress, Schizofrenia or Psychopathy, the list could go on. The simple reason is that the brain is not well enough understood. The states of love or jealousy hasn't been proven either, yet no-one that has experienced either would deny its existence.

True. As with most medication very rare cases of severe side-effects are documented and so noted at package or inlet. Eating too much salt may cause horrendous side-effects too. Science does almost universally consider Ritalin a very safe medication. Maybe even more so than salt.

False. Diagnosing ADHD includes exactly the process of eliminating or confirming other disorders. It is usually even stated in the formal diagnostic criteria that no other diagnose that can better explain the symptoms may exist.

In the context of Scientology the argument becomes usable for every single psychological disorder and probably most diseases as well. "Looking further" means realising that the symptoms are caused by "body thetans" (restless souls that have invaded our bodies) and the only way to get rid of them is by applying Scientology "technology". This is in the realm of religion, not science.

Unknown. What if anything else had happened in Einsteins life? Anything may have altered the cause of his life and history as we know it. If Einstein would have had access to modern ADHD understanding, coping and combined treatment options the answer is clear though: We would leave the question to Einstein.
