Attention Deficit Hyperactivity
Disorder, Fetal Alcohol Effects and Use of Stimulant Drugs in Native Children By David Walker, Ph.D.
Attention-Deficit Hyperactivity Disorder (ADHD, 314.0) is a
psychiatric diagnosis described in the Diagnostic and Statistical Manual for Mental
Disorders (DSM) published by the American Psychiatric Association (1994). This publication
contains behavioral descriptors and diagnostic labels for numerous so-called "mental
illnesses" relevant to the medical model of psychiatry. The descriptors and labels
themselves have been compiled across multiple versions of this publication. Each version
has involved achieving a consensus of many professionals with huge conceptual,
theoretical, and technical differences of opinion working within the field of behavioral
health.
Despite the dominance of psychobiological philosophies in
psychiatry and psychology, there is often great debate as to the validity of the concepts
and categories in the DSM, particularly regarding their scientific basis. Indeed, Harold
Pincus, Vice Chairperson of the Task Force on the DSM-IV, recently
criticized the "evidence-based" approach to the DSM-IV which he oversaw (personal
communication). Dr. Pincus has also noted elsewhere that "there has never been any
criterion that psychiatric diagnoses require a demonstrated biological etiology . . . in
fact, virtually no mental disorder, except those that are substance induced or due to a
general medical condition, has one." Numerous other professionals in behavioral
health have complained about the "low level of intellectual effort" in DSM
construction where "diagnoses were developed by majority vote on the level we would
use to choose a restaurant" (Paula Caplan, Ph.D., Brown University, notes on DSM
Task Force observations, see also her book They Say Youre Crazy, 1995).
ADHD continues to be discussed in relation to alleged neurological
mechanisms using biased, poorly-conceived, poorly-controlled, and poorly-designed
"pseudoscientific" research. Findings from this "research" are
restated to patients as though they are "fact" or "conclusive
evidence" by providers who either lack the expertise or the time for critical
evaluation of their claims. These providers then unwittingly or negligently characterize
social, behavioral, political, and existential problems of living among their patients as
the result of chemical imbalances and biological deficiencies.
ADHD is not, however, recognized as a neurological syndrome by
neurology, a specialty in medical science that, one would hope, would be the gatekeeper
for the legitimacy of such claims. To date, there is absolutely no established, credible
evidence for a biological or neurological basis for ADHD, despite claims to the contrary
based on the aforementioned and numerous pseudoscientific studies funded generally by
psychopharmacological manufacturers and other interested parties.
There is no greater demonstration of this type of unethical
activity nor its potential culturally-oppressive and deleterious effects than in the
diagnosis and medicating of Native children. Despite the lack of credible evidence for the
validity of ADHD and its putative biological underpinnings, providers, families, and even
children across Indian Country continue to subscribe to the legitimacy of the ADHD
diagnosis and the usefulness of treating it using stimulants.
Cultural Biases in the ADHD Phenomenon
William Casey, MD, Chair of the Division of Pediatrics at
Childrens Hospital in Philadelphia (1998) noted that despite general agreement as to
the existence of a small group of "hyperkinetic" children (about 1%),
"abnormal behaviors" related to ADHD diagnosis such as activity,
inattentiveness, and impulsiveness are indistinguishable from normal temperament
variations. He rightly points out that questionnaires used in diagnosis such as the
Connors Rating Scale are poorly-constructed, highly-subjective, and impressionistic.
From the standpoint of psychological and behavioral test construction, the Connors and
similar ADHD rating scales have poor psychometric validity and reliability. That they are
widely used and accepted anyway is not surprising because they add credibility to the
pseudoscience of ADHD. However, as Dr. Casey indicates from the point of view of a
pediatrician, ADHD "fails to achieve the evolutionary perspective that the behaviors
valued as trouble in the modern classroom may have had survival value" at
one time.
This is an essential point in considering the exploitation and
biases of the ADHD diagnosis (and many other psychiatric diagnoses for that matter) in
situations that involve the intersection of two or more cultures. Among the Yakama people
in Central Washington, for example, high value is placed upon traditional forms of
"apprenticeship" learning, which have been practiced successfully in teaching
young people for thousands of years. Sitting at the feet of an elder and learning through
story-telling or following the actions of a mentor through modeling, imitation, and
hands-on explanation are common, continuously-practiced approaches to learning. These are
not a "resurgence" of "lost culture"; they have been practiced
continually here for more than 12,000 years. One can witness these forms of apprenticeship
learning in craft production, fishing, hunting, spiritual practices, and a myriad of other
types of behavior being learned among everyday by Yakama children and adults.
People of the Yakama Nation have had an ambivalent relationship
with formal Western-style education over the recent past. While many support and celebrate
educational achievement, caretakers also frequently desire to sustain strong cultural
identity in their children. Historically, boarding schools and public schools used a
variety of extreme formats, curriculums, and methods aimed to suppress or destroy that
cultural identity. Thus, some families have grown rightfully suspicious of both the means
and agenda within their childrens formal education.
Without even considering its suspect validity in Western social
science, the ADHD diagnosis is clearly inappropriate for Native children living within
such an intercultural dynamic. Yakama Nation children accustomed to apprentice and
action-oriented learning in their families will be culturally-predisposed to have trouble
accommodating quickly to the demands of public school classrooms which expect them to sit
still, to manage time with obsessive precision, and to learn effectively via instructional
approaches that rely heavily on verbal instruction and written task performance. This is
not to suggest that Yakama children are unable to make such accommodations, only that
culturally-insensitive instructional methods sabotage and undermine their adaptation.
Instead of receiving culturally-attuned instruction and adjustments to curriculum that
enhance their intercultural adaptation, the current system misidentifies them as
disruptive and "disordered", frequently using ADHD or conduct disorder
diagnoses, and they are frequently placed on psychiatric medications.
With this turn of events, public education and health care systems
serving Indian people have failed these Native children, provided a rationale for
"pathologizing" their culturally-preferred learning styles, attached the ADHD
label, and subjected them to chemical exposure to substances that truly do create
neurological damageamphetamines. The process through which this occurs is fueled by
well-intentioned but poorly-informed educators and providers complicit in a phenomenon
indistinguishable from other historical forms of institutional oppression.
Hazards of Stimulant Therapy in ADHD
The Drug Enforcement Agency indicated in 1995 that the U.S. was
manufacturing and consuming 5 times more methylphenidate or MPH than the rest of the world
combined. This corresponded to a near six-fold increase in manufacturing since 1990.
Proponents of ADHD claim that these increases represent a breakthrough in detection and
diagnosis of the putative disorder and point to the many testimonials of
"improved" function in allegedly affected children. However, the DEA notes that
because MPH has the same sedating effect on so-called "normal" children and
adults, "behavioral or attention improvements with MPH treatment are not diagnostic
criteria for ADHD." In other words, simply because a child becomes more compliant,
easier to manage, and more amenable to the demands of a classroom with stimulant therapy
in no way suggests the legitimacy of a ADHD diagnosis.
Ritalin (MPH) is a stimulant drug like its frequently prescribed
amphetamine cousins, Dexedrine and Adderall. These drugs are frequently viewed as
"safe" for children, despite their class as Schedule II controlled substances
having the highest potential for addiction and abuse. For example, a popular ADHD study
supporting the use of these drugs and their safety was mounted by the National Institute
of Mental Health. Yet this study exemplifies the pseudoscience of ADHD: there are no
placebo-controlled double-blind designs, the resulting observations of blind observers as
to the equivalence of behavioral treatments and drugs is not even mentioned in the study
conclusions, 32% of subjects were already on stimulant therapy at the start of the study
in a highly-selective process that pulled only 579 subjects from a pool of over 4500,
children did not rate themselves as improved with stimulants, and 80% of subjects were
boys. Clearly, this does not represent a random, representative study with careful
procedures and interpretations of the findings. However, health care providers point to
studies of similar quality alongside a clinical mythology when they suggest that the rate
of stimulant-induced psychoses and other side effects among children is low (about 1% is
often contended).
In truth, there is no scientific basis for such claims and the few
studies capable of obtaining funding for such a question suggest the contrary. For
example, in a carefully-constructed, double-blind study of 98 children placed on MPH
therapy for ADHD, 9% or nearly 1 of 10 children developed psychotic symptoms of
hallucinations and paranoia (Cherland, E & Fitzpatrick, R, 1999, Psychotic side
effects of psychostimulants: A 5-year review, Canadian Journal of Psychiatry, 44,
811-813). Peter Breggin, MD, Director of the International Center for the Study of
Psychiatry and Psychology in Bethesda, MD, and a prominent critic of stimulant therapy in
children, contends that children suffering from such side effects are being misdiagnosed
as having "depression" or "bipolar disorder" that has been
"unmasked" by the medication. Instead, these and other cognitive, emotional and
behavioral problems are occurring directly as a result of stimulant therapy.
Stimulant therapy contains genuine hazards. Methyphenidate,
amphetamine, and cocaine evoke cross-addiction tendencies because they each affect similar
neurotransmitter systems. NIH researcher Nadine Lambert recently presented data suggesting
migration of child prescription stimulant users to cocaine abuse (NIH Consensus
Conference: Diagnosis and Treatment of ADHD, November 16-18, 1998, Bethesda, MD). In
humans and animals, other research suggests that these drugs can drastically and
permanently change brain chemistry, produce brain cell death, retard growth hormone
secretion, and endanger cardiovascular function (Breggen, 1999). Harmful effects also
include hypertension, mental confusion, anorexia, abnormal liver function, endocrine
imbalances, blurred vision, headache, dizziness, insomnia, depression, and irritability.
Ritalin, Dexedrine, Adderall, and similar drugs all have the
effect of sedating spontaneous behavior in humans and animals. These same effects are
frequently mistaken as desirable outcomes in the treatment of ADHD. For example, both
humans and animals taking stimulant drugs have been observed to engage in compulsive
persistence at meaningless tasks, and show mental rigidity and overly narrow focus when
presented with problems demanding creativity. They also become compliant in structured
environments, somber, subdued, apathetic, drowsy, bland, emotionally flat, and generally
lacking initiative and inquisitiveness. Finally, they show increased withdrawal and, in
children, diminished overall play (Breggin, 1999).
PTSD, Denial of Trauma, and the "Attractiveness" of
ADHD
Trauma to a human being is simultaneously a physical, emotional,
cognitive, and spiritual experience. Trauma, according to the DSM definition, consists of
events experienced by, witnessed by, or confronting a person that involve actual or
threatened death, serious injury, or the physical integrity of self or others. In this
definition, trauma also includes intense fear, helplessness, or horror. From a
physiological standpoint, such trauma drives the nervous system through secretion of
epinephrine and norepinephrine, coriticosoids, oxytocin, vasopressin, and endogenous
opioids. On an emotional basis, children and adults experience dissociation or a feeling
of unreality or disconnection in response to the event(s), overwhelming fear and anxiety,
guilt, and/or emotional constriction or withdrawal. Cognitively, traumatized people lose
the ability to concentrate and attend, report memory disturbances, and engage in
"hindsight bias" or faulty conclusion-building ("it was my fault,"
"I could have done something," etc.). From a spiritual standpoint, experienced
trauma represents a powerful existential dilemma in surmounting obstacles of suffering on
behalf of meaning and growth.
Post Traumatic Stress Disorder (PTSD, 309.81) is a DSM descriptor
for the repeated re-evocation of all of these physiological, emotional, cognitive, and
spiritual responses in individuals who have experienced trauma. At Yakama Nation, many of
these traumas come in the form of physical and sexual abuse and domestic violence.
However, there are other sources of trauma as well such as bystander violence, motor
vehicle accident, workplace accidents, and natural disasters as well as the special case
of cultural oppression described below. Because violence in families (physical and sexual)
tends to be repeated across generations (that is, when left unacknowledged and unhealed),
PTSD within families is often called "intergenerational" or
"multigenerational."
Additionally, PTSD can emerge from war and oppression as a facet
of what has sometimes been called "refugee syndrome." This form of PTSD occurs
as a result of torture and deprivation strategies on the part of the aggressor. At Yakama
Nation, for example, U.S. soldiers at Fort Simcoe forced Native women to perform sexual
favors for them while their husbands and partners were compelled to observe and held at
gunpoint (see Click Relanders book, Drummers & Dreamers, 1953). As well,
when men and women engaged in domestic violence in the early days of Yakama Reservation,
they were sentenced to severe public floggings at a whipping post. Numerous stories of
physical and sexual abuse can be obtained from Yakama elders in relation to their boarding
school experiences in a variety of settings, including Fort Simcoe. Among cultures
experiencing such events through ethnocide or forced assimilation, numerous researchers
have noted patterns of "internalized oppression" (also called "Stockholm
syndrome"), which involves inflicting violence on others by identifying with the
initial aggressor (see Duran & Durans book, Native American Post-Colonial
Psychology, 1995; also see Yellow Horse Brave Heart, M. & DeBruyn, L., 1998, The
American Indian Holocaust: Healing Historical Unresolved Grief in American Indian and
Alaska Native Mental Health Journal, 8:2, 60-82). Also seen are the emergence of
survival strategies in the form of over-compliance, emotional suppression and cognitive
withdrawal from the oppressing culture (compare "dissociation" in individuals
with PTSD).
Individuals and communities alike develop strategies to survive
trauma that often include means for denying its effects. Denial under such circumstances
becomes part of community organizational and institutional systems as groups of affected
individuals come to work together. However, such denial cannot be maintained forever
without constricting the growth of both individuals and communities, contributing to
chronic depression, hopelessness, violence and cycles of abuse, suicide, and substance
abuse.
At Yakama Nation, one sees clear indications of Native clients
with intergenerational PTSD that have linkages to local cultural and political historical
trauma from boarding schools to fishing rights. There are also clear examples of multiple
severe traumas occurring within the life-span of individual patients from families
affected by these events. This is sometimes referred to as "lateral trauma"
within a given community. In PTSD terminology, "cumulative trauma" increases the
number of stimuli representing possible sources of traumatic re-experiencing rises as each
PTSD-related event occurs. Thus, multiple cases of physical or sexual abuse or witnessed
violence in the environment and in the home exacerbate the cumulative post-traumatic
stress of a specific survivor.
For children, PTSD is even more devastating than for adults. PTSD
interferes tremendously with attention, concentration, and cognitive and emotional growth.
Cumulative PTSD in childhood equates with a pattern of social, emotional, and cognitive
withdrawal, conduct problems, and chronic anxiety which contributes to school failure,
hopelessness, substance abuse and suicide in early adulthood (see Walters & Simoni,
1999, Trauma, Substance Use, and HIV Risk in Urban American Indian Women in Cultural
Diversity and Ethnic Minority Psychology, 5:3, 236-238; Chester & Rasmussen, 1998,
Intimate Violence In a Southwestern American Indian Community, Robin in Cultural
Diversity and Ethnic Minority Psychology, 4:4, 335-344 ; Gutierres & Todd, 1997,
Impact of Childhood Abuse on Treatment Outcomes of Substance Users in Professional
Psychology: Research & Practice, 28:4, 348-354). Since the diagnosis of PTSD has
considerably greater relevance to the Yakama Nation community experience and greater
clinical validity both interculturally and within the behavioral health community, this
state of affairs reveals an ethical crisis.
Fetal Alcohol Syndrome and Fetal Alcohol Effects as Additional
Contributants
A sizeable but unspecified number of children at Yakama suffer
from the effects of prenatal and neonatal alcohol exposure. There are innumerable
developmental and behavioral difficulties manifested by such children including difficulty
structuring work time, learning impairments, low attention span, impulsive activity, and
unresponsiveness to verbal limit-setting among others (National Organization on FAS, 2000,
www.nofas.org). Thankfully, there are also numerous educational and behavioral strategies
that can help these children to adapt successfully to the classroom. Use of stimulant
drugs with FAS and FAE children is controversial. Clearly, the sedative and restraining
effects of these drugs is the means of action through which they become desirable for use
with these children. Thus, the fact that they may promote greater manageability of FAS and
FAE children does not mean that they have any sort of therapeutic effect at all on
learning or other developmental skills for the child per se. They only afford more options
for the caretaker.
Indeed, given the overall hazards of stimulant therapy mentioned
above and a general consensus in the field of neurorehabilitation that drugs that can
cloud consciousness have stronger experiential effects and are even more undesirable in
helping patients coping with brain injury to learn, this class of drugs appears
contraindicated as a therapeutic agent. The National Institute of Health has continually
reemphasized the need for stronger research on FAS/FAE treatment in Indian Country and,
thus far, solid research on treatments and their efficacy has not been forthcoming. In
general, however, special training of educators in unique behavioral learning approaches
has received the strongest support to date as an intervention strategy with these
children.
Misdiagnosis of children with prenatal and neonatal alcohol
exposure as ADHD followed by secondary exposure to the potential neurological damage of
stimulant therapy is another example of an ethical crisis. In such circumstances, the
potential these special children might possess is significantly undermined on behalf of
the behavioral management agenda of caretakers responsible for serving their needs.
