Reasons for the Increase in ADHD Diagnosis
The question remains to be answered: why are ADHD diagnoses
and Ritalin prescriptions increasing so rapidly? A few possibilities include:
- Dr. Sally Latel, a psychiatrist and AEI fellow, claims
that "Today, children suffering from ADHD are simply less likely to
slip through the cracks." (Fumento, 2003)
- There is now a fairly rigorous testing process in place
(described in the Diagnosis section of this website) which, if used by
a properly trained physician, should be able to differentiate between ADHD
and non-ADHD children.
- Girls who display the Inattentive type ADHD are being
diagnosed at a growing rate, probably because in many cases these symptoms
went unnoticed in the past because they were not as pronounced as hyperactive
symptoms, which are more prevalent in boys (Biederman, et al., 2003)
A recent study found that individual states are prescribing
stimulants at varying rates, with more prescriptions being given in upper-class
communities (Medical Letter on the CDC & FDA, 2003). Also, the United
States consumes 90% of the world's supply of Ritalin, a rate that is five
times that of the remainder of the world combined. (http://www.pbs.org/wgbh/pages/frontline/shows/medicating/backlash/un.html)
Pro-medication advocates interpret these statistics to
mean that many children who would benefit from drug treatment, including
those from poorer communities and countries with less-developed systems
of medicine, are not getting the pharmaceutical treatment they need to help
them control the symptoms of ADHD. Indeed, Ritalin effectively alleviates
the symptoms of ADHD in 75 to 90 percent of ADHD cases according to several
reports, (http://www.chadd.org, Fumento,
2003) which suggests that it is effective when needed, although medication
coupled with cognitive-behavioral therapy is considered to be the most effective
form of treatment.
However, evidence does not suggest that the increase in
ADHD diagnoses is due entirely to improved diagnostic criteria and more
appropriate diagnoses:
- The actual evaluations carried out by psychiatrists and
physicians are, in many cases, widely divergent from those suggested by
the American Academy of Pediatrics.
- One percent of doctors are responsible for a majority
of methylphenidate prescriptions. (http://www.pbs.org/wgbh/pages/frontline/shows/medicating/backlash/un.html)
- According to Dr. Peter Williamson, many physicians diagnose
ADHD after brief interviews of under 30 minutes in duration with the children,
who then receive prescriptions for Ritalin or another medication.
It seems that, in many cases, the physician's attitude
is "Let's try a drug therapy and see if it works; there's no sense
withholding medication from someone who might benefit from it." This
indiscriminate attitude is problematic for a number of reasons:
- The vast majority of people who use Ritalin respond positively
in terms of ability to focus and concentrate, regardless of whether or
not they demonstrate symptoms of ADHD. Thus, doctors may find that patients
do indeed respond positively to Ritalin treatment though they may have
been functioning in a healthy manner without the drug.
- According to Dr. Peter Williamson, the best form of treatment
of ADHD, in general, is drug treatment to alleviate immediate symptoms
coupled with cognitive and behavioral therapy to develop coping strategies.
Emphasizing only the drug treatment serves to alleviate symptoms but may
not be the best form of long-term treatment for those who suffer from ADHD.
- Indiscriminate prescriptions of Ritalin and other stimulants
becomes an even greater concern when the issue of growing prescription
stimulant abuse is taken into account, a problem with a myriad of associated
issues. In 1996, the DEA stated in reference to Ritalin: "These drugs
have been over-promoted, over-marketed and over-sold, resulting in profits
of some $450 million annually. This constitutes a potential health threat
to many children and has also created a new source of drug abuse and illicit
traffic" (http://www.add-adhd.org/ritalin.html).
The DEA concluded that in many cases Ritalin prescriptions
are a "quick-fix bogus medical practice." After reviewing the
wealth of literature on the rise in Ritalin prescription, these fears seem
well-founded.
