No results, bad results and falsified results!

A story about stimulants to adults “with ADHD” in a trial project in Norway

Since 1997 around 1300 adults “with ADHD” have been prescribed stimulants (mainly methylphenidate, Ritalin) in Norway. The “treatment” was part of a trial project that ended in the middle of 2003.

 

The main result from this project is that around 70 % of the treated persons dropped out – they discontinued the treatment of their own volition due to no or bad results!

 

This article is about falsified results – how to present bad results as good results!

 

It takes up how the research team headed by the leading Norwegian proponent for stimulant treatment, neurologist Nils Olav Aanonsen, has presented results in a misleading way, and based on these false results, has recommended continued use of stimulant treatment for adults.

 

The article also takes up how the Swedish National Board of Health and Welfare has used the false results, “the experiences” from Norway, to implement recommendations about increased prescription of stimulants to adults in Sweden.

--------

This year Aanonsen and his team gave out the final report from the trial project (1997-2003) [1]. The report was immediately “released” to Norwegian media and created headlines like Ritalin gives adults with ADHD a better life.

 

The report – with its falsified results – will be used in several countries as support for increased prescriptions of stimulants to adults “with ADHD”.

 

Therefore the truth about the falsifications needs to be revealed.

 

The truth about the bad results revealed in an “internal letter”

 

In 2001, when the project had been ongoing 4 out of 6 years, Nils Olav Aanonsen wrote a letter to the Swedish psychiatrist Lars-Olof Janols [2]. Aanonsen wrote about the project and the results obtained. The letter was a good example of the sincerity and outspokenness found only between colleagues; the content in the letter was not at all meant to reach the public.

 

Lars-Olof Janols was working with a manuscript about treatment with stimulants, for the Swedish National Board of Health and Welfare. His data were to be included in the book ADHD in children and adults, which the Board was about to publish. As many more adults in Norway than in Sweden had been prescribed stimulants, the experiences from the project were important to include in the book.

 

In the manuscript [3], sent to the National Board of Health and Welfare, Janols gave a pithy summary of the results described in Aanonsen’s letter. He wrote:

 

“Insufficient treatment effects, adverse effects, insufficient support actions ahead and inability among the persons to take part in the treatment and in the regular examinations are viewed as the cause for the dropout of 70 % [of the patients].”

 

Aanonsen wrote in the letter about the “dropout” of patients: “With our system of back reporting we know from experience that only around 30 % choose to take it [the ‘medication’] one year or more.”

 

The main result was that 70 % of the patients discontinued the treatment!

 

The majority of the patients received methylphenidate (Ritalin).  Let’s assume for a short while that ADHD is a real medical disorder and that Ritalin would be a medical treatment. Let’s look at the website of Novartis, the maker of Ritalin, where descriptions of ADHD and its treatment are to be found [4]. It is said: “ADHD is a medical disorder associated with the balance of chemicals (neurotransmitters) in the brain.” And about the medication: “Stimulant medications help the brain normalize the activity of certain chemicals that are affected by ADHD (these chemicals are known as neurotransmitters).” It is even said: “Stimulants are designed to restore the natural balance of the chemicals in the brain affected by ADHD.” [Emphasis added.]

 

But 70 % of the patients discontinued the treatment. They did not seem to get the “natural balance” in the brain that Novartis had promoted. On the contrary – they fell off due to no or bad results. As Aanonsen, who thought the activity worked well administratively, said in his letter: “The therapeutic successes are more varying.”

 

The patients who ended the treatment must have agreed to the conclusion given in the letter that “…the effect does not seem to be of so good help on general psychosocial ability as one could believe after the first months´ often remarkable response on the ability to concentrate.”

 

Aanonsen can’t be very pleased that the information in his letter about the insufficient therapeutic successes has leaked out. This especially, when he, this year, has released the official report about the project saying that treatment with stimulants “works” – that it enhances the life quality of the patients! (More about the report later.)

 

The reason for the dropout of 70 % of the patients was, as Janols wrote:

a)      Insufficient treatment effects

b)     Adverse effects

c)     Insufficient support actions

d)     Inability among the persons to take part in the treatment and in the regular examinations.

 

In summary: The project had so far proven to be a complete failure. The only possible conclusion should have been that treatment with stimulants has no role in “evidence-based medicine”; it does not even work as behaviour control.

How did the Swedish National Board of Health and Welfare handle the information?

 

The information from Janols, including the summary of the catastrophic results, was sent to the National Board of Health and Welfare and the person responsible for the editing of the book ADHD in children and adults, the paediatrician Björn Kadesjö.

 

The information was not used! In the book ADHD in children and adults important referrals were made to the experiences in Norway but none of the data above were taken up [5].

 

Primarily one did not take up the most obvious result – that 70 % of the patients ended the treatment because it did not work in the way Novartis and concerned psychiatrist say!

 

Professor Sten Levander, who was part of the expert group working with the ADHD book for the National Board of Health and Welfare wrote in his manuscript [6] that there is “no medical point in trying to discontinue the treatment each year with the risks associated…” but “at least every fifth year one should decide if one should reconsider the medication via a controlled discontinuing trial.“  The patients in Norway however found quite some medical points in ending the treatment with stimulants long before that point – it gave no or few results but quite some adverse effects.

 

Even if Björn Kadesjö took his information about treatment of adults “with ADHD” from Janols manuscript, he succeeded to completely omit all data about the bad results from Norway. Instead he referred to an intermediate report issued by Aanonsen, March 2000 [7], and said that the experiences from Norway of a group of 39 patients treated one year showed that the treatment gave “very good effect on at least 2 of 7 ADHD related symptoms”.

 

A closer look reveals that these 39 patients were not part of a controlled trial (as one could believe from the text). Instead they were just part of the patients in the project. They were the patients left after a year, of a group of 90 – where 51 persons dropped off before! For these 51 persons (57 %) no results were described.

 

 

The final report from Norway about the trial project

 

Aanonsen was very outspoken in the letter 2001 to his colleague Janols. The insufficient therapeutic successes, the many patients choosing to end the treatment and the threatening “demotivating” treatment situation were the things in focus.

 

When Aanonsen, in February this year, released the final report about the project, it sounded differently. Politicians and the public get a well-arranged story. But even if other things now came in focus and even if well selected statistics should prove that treatment with stimulants was a “working treatment”, it was impossible to hide the “internally” revealed truths.

 

A review of the report shows the following:

 

·        Aanonsen choose to neglect that a 70 % dropout of patients due to no or bad results is the principal experience from the trial project! Of the in total almost 1330 patients who had got stimulant treatment, 262 patients had got it during a period of 2 years and 1066 patients had got it a shorter time. About the group of 1066 patients very little is said in the report.

 

For 526 patients in the large group (1066 patients), who at the point of measurement 2003 could not have got stimulants during 2 years – they started “too late” – no results are noted.

 

Incredibly enough reports from 129 patients, who started the treatment earlier, are also missing. Aanonsen says (p. 26): “Due to lack of back reporting the treatment process for 129 patients was uncertain.” In the claimed administratively well functioning activity, with its “stiff routines for quality control”, no information was reported about 129 patients – 12 % of the remaining group. It was not known how long they had been treated and no results were known. Probably it is not too risky to say that the results in this group would not fit well in the final publication. The group of 129 persons could be compared with the group of 262 persons – the persons who got stimulants for 2 years. The difference was that the last group was described in 25 (!!) tables and graphs in the report, where also the subjective reports from the patients were given a lot of space, while the first group got no descriptions at all.

 

But for 411 patients who had discontinued the treatment, reports were turned in and results noted in the report – even if no graphs at all over subjective views on “target symptoms” are available.

 

About the reasons for discontinued treatment it is noted (p. 27):

 

·                That 43 % (n=175) of the patients ended the treatment due to adverse

effects.

·                That 36 % (n=146) ended the treatment due to “little or no effect”.

·                That for 16 % (n=65) of the patients the treatment was ended due to “lack

of compliance” – the patients did not take the “medication” as they should.

·                That for 13 % (n=52) of the cases the treating physician had to end the

treatment due to drug abuse.

(Graph made from the text in the report.)

 

There could be more then one reason noted for discontinuing the treatment, and the percentage exceeded 100. Under the heading “Other” 25 % was noted. The reasons could be everything from “without noted reason” to “suicide attempt, other acute psychiatric disease/psychosis, criminal behaviour, serving sentence”. No further details or numbers are noted about this in the report.

 

 

(Graph made from the text in the report.)

Of the 411 patients 175 had directly noted adverse effects as the reason for discontinuing the treatment. In Aanonsen’s text one can see that these patients had got the adverse effects illustrated in the above diagram. (The persons had noted more than one adverse effect; the sum is more than 100 %.)

 

43 % of the 411 patients discontinued the treatment due to adverse effects. Estimating that the 129 patients, not accounted for, have ended the treatment and that 70 % of the 526 patients not included at the point of registration 2003, have done the same or will do so, (70 % is the estimated figure earlier reported by Aanonsen), means that another 500 patients have ended the treatment (or will soon do so). It is reasonable to assume that the figure 43 % is representative also for this group, which would mean that close to 400 patients ended/will end the treatment due to the type of adverse effects illustrated above. Around 150 of these can be expected to suffer from depressive mood and anxiety as a direct effect of the stimulants.

 

In the report Aanonsen is not at all considering these adverse effects as a problem. He writes (p. 55):  “All in all the above experiences do not give reason for worry about considerable adverse effects or serious complications in the treatment of adults with hyperkinetic disorder/ADHD with stimulant medication.”

 

One can ask what is needed regarding adverse effects for “worry” to arise! Compared to the group of 262 persons taking stimulants for 2 years it is probably almost the double amount of persons, around 400, who has ended/will end the treatment due to adverse effects.  The “risk-benefit balance” for amphetamine is hardly favourable!

 

Over 92 % of the patients discontinuing the treatment did this for “negative reasons” (see above). But Aanonsen is in the report more interested in the 5,6 % (23 persons!) ending the treatment due to not “needing” the drug any more (1,9 % ended due to pregnancy). The fact that 23 patients discontinued the treatment for this reason, leads to the following incredible conclusion (p. 55):”…some patients who have chosen to end the treatment have stated as reason for this that they have achieved a good enough functioning.” “This can indicate that the starting of treatment with stimulant medication for hyperkinetic disorder/ADHD in adults, not necessarily means a life long treatment. A shorter or longer period with drug treatment can be assumed to help a person turn a negative situation, get on a better track and manage to benefit better from other treatment.”  That 380 persons ended the treatment for “negative reasons” did not lead to any general conclusion about the workability of the treatment, but the 23 patients who could do without the drug, lead to the above!

 

·        One of eight persons, 12,5 %, ended the treatment due to drug abuse. 52 persons out of the group of 411 were taken off the treatment due to abuse. It has been said that drug abuse is a form of “self medication” for persons “with ADHD”, who have been “denied” treatment with stimulants. When the correct treatment now is given; the treatment that according to Novartis restores “the natural balance” in the brain, the result is that 12,5 % of the patients in this group starts or continues to abuse drugs. Considering the insufficient follow-up procedures (see example about the 129 patients) the actual amount of persons abusing the prescribed “medication” and other drugs, is very likely much higher, as Aanonsen also says, p. 52: “here it can be a matter of underreporting”.

 

On page 19 in the report one can see that around 25 % of all persons who have been prescribed stimulants also have got the same “medication” earlier, based on an ADHD diagnosis or similar (MBD). This is also true for the persons who now have been prescribed stimulants for 2 years (p. 31). An interesting question is if the group of persons that earlier (as children) got stimulants, in a high or low degree corresponds with the group that have developed a later addiction. If a high degree of correspondence exists it would be a powerful contribution to the theory that early treatment with stimulants leads to later drug abuse. Aanonsen writes nothing about this but should absolutely get the chance to account for this relation.

 

·        It is very clear in the report that the treatment does not “work” at all for “difficult cases”, for criminals and for persons who quite recently have abused drugs. This must be a big problem for Aanonsen and other proponents of stimulant treatment. It is not possible – or at least should not be – to prescribe drugs classed as narcotics with a high potential of abuse to persons with “mild problems”. The very reason for prescribing narcotics is the really difficult problems: “other measures have not been enough”; as a last measure a trial with stimulant treatment is needed; a group of persons with very severe problems makes it necessary to…

 

It is certainly primarily these persons Aanonsen described in his internal letter to Janols 2001, when he in a complaining voice wrote that there was an “inability among the persons to take part in the treatment and the regular examinations” and “for some patients one can get the impression that they need a doctor full time to function in an acceptable way.”  It was also about the treatment of these persons that Aanonsen wrote that many physicians did find the treatment situation “demotivating” as “many of the patients (20-30%?)” were unusually “conflict oriented”, complained to representatives and reported the doctors to the police!

 

How should Aanonsen, in his position, describe the fact that the treatment of these persons with stimulants is a complete failure – without saying so? He uses some well-proven measures, the foremost being to blame the patients. He says (p. 54) about the persons who were socially maladjusted: “Often there has been unrealistic expectancies that stimulant medication will lead to big changes in behaviour, something which in practice not often has been the case.”

 

Also the persons who not too long ago had been abusing drugs and alcohol (p. 52) “had unrealistic expectancies that stimulant medication should contribute to a lowered urge for drugs or remedy a difficult situation.”

 

The persons had “unrealistic expectancies” – maybe they had read the “facts” about Ritalin published by Novartis or simply had read to many articles in medical journals or in newspapers that Ritalin gives adults with ADHD a better life!

 

Now at least they know that this was not true.

 

·        In the report the subjective evaluations for the large group that ended the treatment have been completely omitted, while the results for the group that got stimulants for 2 years have been exaggerated in all possible ways. One must assume that also the patients who discontinued the treatment made a subjective evaluation of the effects from this, after 6 weeks, 6 months and 1 year (if still there). We know from Aanonsen’s internal letter that these evaluations must have been very negative.  How do Aanonsen and colleagues handle this situation to not “disturb” the presentation? They simply omit these evaluations, they do not describe them at all! Instead they choose to describe at length the group that did not drop out with well-chosen diagrams.

 

In the report there is a diagram (p. 42) that shows that the life situation has become better for those succeeding to take stimulants for 2 years, “more positive after starting treatment with stimulant medication”. In an extremely one-sided article in the Norwegian newspaper Aftenposten (Ritalin gives adults with ADHD a better life, 15th of March 2004), Aanonsen says: “Quite some persons experienced a marked increase in life quality.” Looking in the report (p. 42) there is a graph moving in a positive direction, from 3 to 2. If one reads the text to see what these figures stand for it is hard to understand that statements about “a marked increase in life quality” is a fitting description. The figure 3 stands for “moderate maladjustment” and the figure 2 for “mild maladjustment”. The starting point was “moderate maladjustment” and the end result after 2 years, one step better, “mild maladjustment”. The impression is that huge efforts have been made to present some form of social betterment. Behind this presentation lies the true picture about the treatment in general; as Aanonsen said in his internal letter: “…the effect does not seem to be of so good help on general psychosocial ability…” The treatment did not in other words better the life situation in general – and absolutely not for those with big problems.

 

·        In the end of the report (p. 54) there is a passage with the very important conclusion: “However many of the patients got treatment measures in addition to the purely medical. Better life quality therefore can have more explanations in this group and can not offhand be attributed to the stimulant medication.” The slightly rising graphs presented for this group could have been caused by other measures then the “medication”. With this in mind it is fascinating to read the descriptions about the good effect of the stimulants, on the group treated for 2 years, in the newspaper article – it was the drug that caused the betterment. In media it is obviously possible to “offhand” attribute the better life quality to the treatment with Ritalin.

 

·        It is also said (p. 29) that the report neither is planned to be nor designed as a scientific investigation and that all “evaluations of effects, numbers, or conclusions below do not claim to have scientific universality exceeding this material.”

 

The two points above could have been a fitting, humble framing of the report if the head of the project himself took them seriously. But these limitations, these fitting explanations, were not thought to be true in practice. In the “press release” in media (Aftenposten), the trial project was transformed into a “unique Norwegian study” and the heading Ritalin gives adults with ADHD a better life, did fit well with Aanonsen’s statements. It was no longer any problem to “offhand” attribute all betterment to the treatment with Ritalin, and the “conclusions” suddenly got “scientific universality”.

 

·        “If the treatment of children was decided from the children’s own motivation, the compliance could turn out to be of the same magnitude.” This is a fantastic quote from the intermediate report about the project, March 2000. Aanonsen is under the heading About dropouts from the treatment speculating (p. 36) about how it would be if also children treated with stimulants could discontinue the treatment. For adults, as also noted in that report, it could be expected that around 70 % discontinued the treatment themselves. Aanonsen wrote: “If the treatment of children was decided from the children’s own motivation, the compliance could turn out to be of the same magnitude.”

 

But children cannot, as the adults, end the treatment of their own volition. If they could, it would probably lead to that 70 % decided to quit, to no longer accept the fact that they must take amphetamine as a “medicine”.

 

 

What conclusions can be drawn from the experiences with stimulant treatment in Norway?

 

The conclusions and recommendations from the experiences in Norway must be:

 

·        In treating adults with stimulants one can expect that around 70 % of the patients will discontinue the treatment;

 

·        The persons ending the treatment will in 9 out of 10 cases do this due to inadequate therapeutic success, most of them due to adverse effects, inadequate treatment effects and inability to take part in the treatment;

 

·        The persons who quite recently have abused alcohol or drugs, or committed criminal acts, will due to the inadequate treatment effects discontinue the treatment; they will not function better. They will, generally speaking, violate the treatment alliance and return to drug abuse;

 

·        The promises that treatment with stimulants will lead to a “restored natural balance” of chemicals in the brain, made by Novartis, leading psychiatrists and by “patient associations” (as CHADD), have turned out to be false. If the “symptoms” had been caused by a “biochemical imbalance” and if stimulants had corrected this imbalance, the “symptoms” would have disappeared. That has not happened. Thus there is no scientific basis for statements that this treatment is a “workable medical treatment”.

 

·        There is not any longer any reason to assume that the prescription of stimulants to adults would work as a form of positive behaviour control. The expectancies that narcotics should help persons to function better in society have not been fulfilled.

 

·        There is very good reason to believe that also most of the children will choose to discontinue treatment with stimulants – if they were allowed to choose.  In accordance with the UN Convention on the Rights of the Child, children must from here on be allowed to exercise this right to choose.

 

·        The Swedish National Board of Health and Welfare wrote in 1996 [8]: “The National Board of Health and Welfare is in very strong doubt about widening the indications for treatment with stimulants, even with the strict rules suggested. The reason for our position is as follows: Many of the around 8000 drug addicts in the country will set great hopes on ´legal´ prescription. During the 90-ties the National Board of Health and Welfare has only for 4-5 patients supported prescription of stimulants on license, in statements to the Medical Products Agency. Every matter is requiring lots of resources, often followed by appeal and sometimes even threatening calls from the persons whose applications have been disapproved. It will be possible even for amphetamine addicts to claim that they have a diagnosis requiring treatment and to demand analysis to get license prescription. The boundaries will be hard to tell. Sweden will be considered a more drug liberal country. Increased legal prescription of stimulants will obstruct the fight against narcotics.” The experiences from Norway have shown this to be true.

 

 

In summary: Stimulant treatment has been proven destructive both for the individual and the society. It must be banned right away.
