Ritalin: Child Abuse On Prescription?
Family doctors are these
days frequently under pressure (usually from teachers and social workers who
know nothing about drug therapy and probably understand nothing about the way
the international drug industry operates) to prescribe the drug called Ritalin
for children who are accused of behaving badly behaved, reported as not doing
well at school and `diagnosed' as suffering from something called Attention
Deficit Hyperactivity Disorder (known as ADHD).
For several decades
now Ritalin, and other amphetamine type drugs, have been prescribed for children
diagnosed as suffering from various types of brain dysfunction and hyperactivity.
(Other psychostimulants which have, at one time or another, been regarded as
competitors to Ritalin have included Dexedrine).
In my view the first
problem is that Attention Deficit Hyperactivity Disorder (and other variations
on the hyperactivity theme) is a rather vague diagnosis which is often leapt
upon by teachers, social workers and parents to excuse and explain any unacceptable
or uncontrollable behaviour.
Parents of children
whose behaviour is in any way regarded as different or unusual are often encouraged
to believe that their child is suffering from a disease for two simple reasons.
First, it is more socially acceptable to give a child a pseudoscientific label
than to have to admit that he or she may simply be badly behaved.
Second, when a child
has been given a label it is possible to offer a treatment. Commonly it will
be one, such as a drug, which offers someone a profit.
ADHD, which is also known as Attention Deficit Disorder (or ADD), hyperkinetic
child syndrome, minimal brain damage, minimal brain dysfunction in children,
minimal cerebral dysfunction and psycho-organic syndrome in children, is a remarkably
non specific disorder. The symptoms which characterise the disorder may include:
a chronic history of a short attention span, distractibility, emotional lability,
impulsivity, moderate to severe hyperactivity, minor neurological signs and
abnormal EEG. Learning may or may not be impaired.
Read that rather nonsensical
list of symptoms carefully and you'll find that just about any child alive could
probably be described as suffering from ADHD.
What child isn't impulsive
occasionally? What child doesn't cry and laugh (that's what emotional lability
means)? What child cannot be distracted?
One big worry I have
is that Ritalin could be recommended for any child who seemed bored and restless
or who exhibited unusual signs of intelligence or skill. Read the biographies
of geniuses and you may wonder what we are doing to our current generation of
most talented individuals.
`Is Ritalin a drug in search of a disease?' wrote one author, and it isn't difficult to see why.
First Used In The 1960s
Ritalin has been recommended as
a treatment for functional behaviour problems since the 1960s. When CIBA first
suggested this in 1961 they were turned down by the FDA but in 1963 approval
was given for this use of the drug.
By 1966 the `experts' had come up
with a definition of the sort of child for whom Ritalin could useful be prescribed.
Children suffering from Minimal Brain Dysfunction (MBD), the first syndrome
for which Ritalin was recommended, were defined as `children of near average,
average or above average general intelligence with certain learning or behavioural
disabilities ranging from mild to severe, which are associated with deviations
of function of the central nervous system. These deviations may manifest themselves
by various combinations of impairment in perception, conceptualization, language,
memory and control of attention, impulse or motor function'.
Other symptoms which children might
exhibit and which could be ascribed to MBD included: being sweet and even tempered,
being cooperative and friendly, being gullible and easily led, being a light
sleeper, being a heavy sleeper and so on and on.
Given that sort of list to work with it is difficult to think of a child who
wouldn't benefit from Ritalin - though the official estimate seemed to be that
only around 1 in 20 children were real MBD sufferers.
A Convenient Diagnosis
The bottom line is that it has become
easy for social workers and teachers to define any children who misbehaves or
doesn't learn `properly' as suffering from MBD or ADHD. Its a convenient diagnosis
which excuses parents, teachers and social workers from responsibility or any
sense of guilt. How can the parents or the teacher be accused of failing when
the child is ill?
The head of the task force which
identified and labelled MBD allegedly subsequently joined the company making
Ritalin and produced their handbook for doctors on the condition. Commercially
Ritalin and MBD became a huge success. By 1975 around a million children in
the U.S. were diagnosed as suffering from MBD. Half of these were being given
drugs and half of those on drugs were on Ritalin.
For the sake of completeness I should
point out that Ritalin has not always been used exclusively in the treatment
of badly behaved children.
When Dr Andrew Malleson wrote his book `Need Your Doctor Be So Useless' in 1973 he reported that the CIBA Pharmaceutical Company had suggested `to doctors the use of their habit forming drug Ritalin for `environmental depression' caused by `NOISE: a new social problem'.
Does Ritalin Work?
The next question which has to be
asked is: `Does Ritalin work?'
Well, I'm afraid that I can't answer
that question. And I honestly don't think anyone else can either. Novartis,
the drug company which is now responsible for Ritalin in the UK, admits that
`data on...efficacy of long term use of Ritalin are not complete'.
With one in twenty children said to be suffering from MBD (or ADHD or ADD or
whatever else anyone wants to call it), with Ritalin having been on the market
and used for this condition for over three decades, and with some experts saying
that a million children a year are given Ritalin in the U.S. alone you might
find this a trifle disappointing.
Just how long does it take to find
out whether or not a drug works? Am I being horribly cynical in suggesting that
it might be against the drug company's interests to find out whether or not
Ritalin really works? After all, if long term studies found that Ritalin didn't
work a very profitable drug would, presumably, lose some of its appeal.
Some research has been done. One five year study of hyperactive children who
were given Ritalin at Montreal Children's Hospital found that the children did
not differ in the long term from hyperactive children who were not given the
drug. At least one investigator has reported that drugs like Ritalin may produce
a deterioration in learning new skills at school and parents have reported that
the symptoms of MBD have miraculously disappeared during school holidays.
The picture is confused by the fact
that there may be a short term improvement in behaviour among children given
Ritalin. But is this a real improvement? Or is the child simply drugged? Amphetamine
type drugs reduce the variety of behaviour exhibited by children. A child taking
Ritalin might have more focused behaviour. But although that might mean less
disruption in the classroom does it really help the child? And should we give
a child a powerful and potentially hazardous drug because they it keeps him
quiet?
There is evidence suggesting that children who are genuinely hyperactive may have been poisoned by food additives or by lead breathed in from air polluted by petrol fumes. If this is so then is giving another potentially toxic drug really the answer to this problem?
Potentially Toxic
The next problem is that I believe
that Ritalin can reasonably be described as potentially toxic. Ritalin has been
described as `very safe' but for the record here is a list of some of the possible
side effects which may be associated with Ritalin: nervousness, insomnia, decreased
appetite, headache, drowsiness, dizziness, dyskinesia, blurring of vision, convulsions,
muscle cramps, tics, Tourette's syndrome, toxic psychosis (some with visual
and tactile hallucinations), transient depressed mood, abdominal pain, nausea,
vomiting, dry mouth, tachycardia, palpitations, arrhythmias, changes in blood
pressure and heart rate, angina pectoris, rash, pruritus, urticaria, fever,
arthralgia, alopecia, thrombocytopenia purpura, exfoliative dermatitis, erythema
multiforme, leucopenia, anaemia and minor retardation of growth during prolonged
therapy in children.
Doctors who prescribe Ritalin, and
who have the time and the inclination to read the warnings issued with the drug,
will discover that Ritalin should not be given to patients suffering from marked
anxiety, agitation or tension since it may aggravate these symptoms.
Ritalin is contraindicated in patients
with tics, tics in siblings or a family history or diagnosis of Tourette's syndrome.
It is also contraindicated in patients with severe angina pectoris, cardiac
arrhythmias, glaucoma, thyrotoxicosis, or known sensitivity to methylphenidate
and it should be used cautiously in patients with hypertension (blood pressure
should be monitored at appropriate intervals).
Ritalin should not be used in children under six years of age, should not be
used as treatment for severe depression of either exogenous or endogenous origin
and may exacerbate symptoms of behavioural disturbance and thought disorder
if given to psychotic children.
The company selling it claims that
although available clinical evidence indicates that treatment with Ritalin during
childhood does not increase the likelihood of addiction chronic abuse of Ritalin
can lead to marked tolerance and psychic dependence with varying degrees of
abnormal behaviour.
Ritalin, it is warned, should be
employed with caution in emotionally unstable patients, such as those with a
history of drug dependence or alcoholism, because such patients may increase
the dosage on their own initiative.
Ritalin should also be used with
caution in patients with epilepsy since there may be an increase in seizure
frequency.
And height and weight should be carefully
monitored in children as prolonged therapy may result in growth retardation.
(A child might lose several inches in possible height - though if treatment
is stopped there is a generally a growth spurt). It is perhaps worth mentioning
here my view that if a drug is powerful enough to retard growth it does not
seem entirely unreasonable to suspect that the chances are high that it may
be having other powerful effects upon and within the body.
Doctors are also warned that careful
supervision is required during drug withdrawal, since depression as well as
renewed overactivity can be unmasked. Long term follow up may be needed for
some patients.
There have also been reports that
children have committed suicide after drug withdrawal. And one study has shown
that children who are treated with stimulants alone had higher arrest records
and were more likely to be institutionalised.
Long term use of Ritalin has been said to cause irritability and hyperactivity
(these are, you may remember, the problems for which the drug is often prescribed).
In a study published in Psychiatric Research and entitled Cortical Atrophy
in Young Adults With A History of Hyperactivity brain atrophy was reported
in more than half of 24 adults treated with psychostimulants (though I don't
think anyone can say for sure whether or not the psychostimulants caused the
brain atrophy the possible link should make prescribers, teachers and parents
who are fans of Ritalin stop and think for a moment).
In Johannesburg a study of 14 children
is said to have produced a response in only 2 children. One child showed some
deterioration and another showed marked deterioration.
The final insult is, surely, the
fact that the company selling Ritalin tells doctors that `Data on safety and
efficacy of long term use of Ritalin are not complete.' For this reason they
recommend that patients requiring long term therapy should be monitored carefully
with periodic complete and differential blood counts, and platelet counts.
I regard this as an insult because Ritalin is not a new drug.
I have not, at the time of writing
this, been able to find out exactly when it was first introduced but I have
been able to trace it back to 1961.
Now, maybe I'm being rather demanding but it does seem to me that when a drug has been on the market for well over a quarter of a century it isn't entirely unreasonable for the drug company involved to have completed studying the data on whether or not it works and is safe.
Cancer In Mice
When early safety tests were done
on mice researchers found that the drug caused an increased in hepatocellular
adenomas and, in male mice only, an increase in hepatoblastomas (described as
`a relatively rare rodent malignant tumour type').
`The significance of these results to humans is unknown' say Novartis, the company
selling Ritalin.
Here, once again, is yet more proof
of the total worthlessness of animal experiments and the ruthless and cynical
attitude shown by drug companies and those government departments which allegedly
exist to protect the public from unsafe drugs.
I have frequently argued that when drug companies perform pre clinical tests
on animals they do so knowing that if the tests show that a drug doesn't cause
any problems when given to animals they can use the results to help convince
the authorities that the drug is safe.
On the other hand when a drug does
cause a problem when given to animals the results can be ignored on the grounds
that `the significance of these results to humans is unknown'.
The question here is a very simple one: if the experiments on mice which showed that Ritalin causes cancer were of value why is the drug still available on prescription for children? And if the experiments can safely be ignored (on the grounds that animals are so different to human beings that the results are irrelevant) why the hell were the tests done in the first place?
Ignorance And Misplaced Trust
My own feeling is that the people
who told you that Ritalin is 'very safe' are either unable to read or too lazy
to do any research into the safety of a product which they are recommending
with such enthusiasm.
Years of experience mean that I am
not in the slightest bit surprised to find such crass stupidity exhibited by
social workers. I am, however, more surprised to find school teachers showing
such a potent mixture of ignorance and misplaced trust. Some observers claim
that Ritalin can be considered for a children when tests and clinical examinations
have shown the existence of a clear neurological disorder - with abnormal brain
wave patterns.
Psychiatrist, psychologist, health
visitor, teachers, GP and parents should, it is said, all be considered before
considering treatment.
Even the company selling Ritalin
says that `Ritalin treatment is not indicated in all children with this syndrome
and the decision to use the drug must be based on the physician's evaluation
of the child's history and the duration and severity of symptoms'.
However, despite this, when a team of researchers from the United Nationals
International Narcotics Control Board examined the records of nearly 400 paediatricians
who had prescribed Ritalin they found that half the children who had been diagnosed
as suffering from MBD (or ADD or whatever) had not been given psychological
or educational testing before being given the drug. The United Nations concluded
that frustrated parents, teachers and doctors were too quick to stick a label
of ADD onto children with behavioural problems (or, to be more accurate, to
children whose behaviour was annoying the parents, teachers and doctors).
Less Than Enthusiastic
I am less than enthusiastic about
this drug. In my view, the world would be a healthier place if all supplies
of this wretched drug were wrapped in concrete and buried in the rubble of the
headquarters of the company making the damned stuff.
You might have guessed by now that
I wouldn't prescribe Ritalin for anyone - for anything.
But other doctors clearly don't agree
with me. Some observers have described Ritalin as a drug that can unlock a child's
potential. And although estimates about the number of children taking Ritalin
vary in the U.S. alone it has been claimed that up to 12 % of all American boys
aged between 6 and 14 are being prescribed Ritalin to treat various behavioural
disorders. In 1990 the world wide production of the drug was less than three
tonnes. By 1994 production of the drug had virtually trebled. It is now not
unknown for schools to arrange for children to be treated with Ritalin without
obtaining parental permission.
It is worth remembering that although
doctors, parents and teachers have for over thirty years now been enthusiastically
recommending the use of Ritalin (and similar drugs) in the treatment of MBD
there are still a number of unanswered questions.
We still do not know whether the drug works and nor do we know whether it causes
any permanent long term damage. We do not know whether the listed potential
side effects do more damage than any possible good the drug might do. And, perhaps
most astonishing of all, despite the fact that millions of children have been
diagnosed as suffering from ADHD, ADD or MBD, and treated with powerful drugs,
we do not even know whether any of these conditions - or hyperactivity - really
exist.
Back in 1970 the Committee on Government
Operations of the U.S. House of Representatives studied the use of behaviour
modification drugs on children. At that time around 200,000 to 300,000 children
a year in the U.S. were being given these drugs and the point was then made
that hyperactivity is considered a disease because it makes it difficult for
schools to be run `like maximum security prisons, for the comfort and the convenience
of the teachers and administrators who work in them...'.
Since then the only thing that has changed is that the popularity of Ritalin
has continued to rise and rise
and rise inexorably.
Prescribing Ritalin is, in my view,
authorised child abuse on a massive, global scale.
But it is clear that the prescribing of powerful mind altering drugs for small
children is big business.
In the US the use of antidepressants
and stimulants among toddlers aged between two and four tripled between 1991
and 1995. The period between birth and four years of age is a time of great
change in the human body. Most importantly it is a time when the brain is maturing.
Heaven knows what effect these drugs have on those tiny developing brains.
Ritalin is now widely prescribed
for toddlers. So are many other antidepressants, stimulants and other powerful
drugs. Remember: typical symptoms of this alleged disease include `restlessness'
and `inattentiveness'.
I am delighted that my protests and
complaints about these absurd and obscene prescribing habits have drawn a number
of vicious complaints from doctors.
In my view every doctor who prescribes such drugs for children with alleged
ADHD should be defrocked, given a good thrashing with genetically engineered
stinging nettles and forced to emigrate to the USA.
