Why has the "syndrome"
approach failed?
The "syndrome" approach to diagnosis, treatment and research
applied to communication and learning disorders has
generally failed so far. Why has the syndrome approach failed? It is
because the currently defined syndromes (i.e. Autism,
ADD, etc…) are defined with respect to "Behaviors,"
which are almost always learned or derived. The exact same learned or derived behaviors
can be caused by completely different biological states
or original traits and their modifiers. In fact,
sometimes the very same learned behavior can be caused
by totally opposite original traits or biological states
(i.e. an "autistic" child may bang his head on the floor
to drown out overwhelming sensory input or may similarly
bang his head to create sensation to break through
extreme sensory insensitivity; or as another example,
very similar behaviors may be caused by serotonin
deficiency or serotonin excess).
The
BOLD Alternative
In
order to simplify this "individualistic 'functional'"
approach, I would like to present a newly derived
"conceptual framework" for addressing communication and
learning disorders. This "conceptual framework" can help
when evaluating a child, to identify and present the
origins and modifiers of his or her behaviors and how
and where intervention may be successful.
The "BOLD" approach consists of four (4) levels of
structure for investigating, evaluating, and treating
these and other developmental disorders. We recommend
that each child’s underlying biological structure be
identified (level 1), each trait or behavior be placed
at the appropriate level (2, 3, or 4), and all
significant and relevant modifiers charted. Once
properly structured, we believe this approach will
clearly identify those behaviors that are modifiable and
recognize potential ways to modify them. For our
purposes, we have labeled this the "BOLD"
Approach to Assessment and Treatment of children with
communication and learning disorders. The
four levels of the model include:
-
Level 1: B - Biological State
-
Level 2: O - Original Traits
-
Level 3: L - Learned Behaviors
-
Level 4: D - Derived Behaviors
BOLD - Level 1: Biological State
These are the genetic and fundamental biochemical and
structural components of the child’s body, brain, and
nervous system that are essentially unchangeable. Note
that certain aspects of the biological state may be
predictable and/or preventable at some earlier point in
development and as technology improves may indeed be
modifiable. However, at the current state of the art, we
must regard them as unmodifiable. The components of the
biological state are:
-
DNA (the basic genetic structure)
-
the brain and nervous system
-
sensory and motor organs
-
the immune system
-
all other biological systems
Level 1
Biological State Modifiers
The
biological state is constantly acted upon by
environmental factors. The end results of these
interactions are the "primary" or "original" traits of
the child’s functioning (Level 2 "traits"). Recently,
researchers have investigated how use of antibiotics
(Bolte, 1998), abnormal sleep patterns (Patzold,
Richdale & Tonge, 1998), diet (Carlsson, 1998), medical
illness (Volkmar, 1998) and epilepsy (Kobayashi &
Murata) have exacerbated the developmental functioning
of children with communication and learning disorders,
especially autism. These external factors are Biological
State Modifiers. Some modifiers include:
-
The Womb Environment: the mother's nutrition, stress,
antibiotics, drug use: street or prescribed, alcohol
or tobacco abuse, diseases (HIV, CMV, chicken pox
etc.), radiation exposure (pre or post
conception)
-
The Birthing Process: use of pitocin, hypoxia
-
Food & Drink: contaminants, food additives, fluoride in
water, vitamin deficiencies
-
The Environment: air, water or noise pollution,
vanishing ozone layer, other noxious stimuli
-
Medical Interventions: vaccinations, inappropriate
antibiotics for otitis media (ear infection) or
pharyngitis (sore throat)
-
Intentional modifying factors: brain surgery,
medications such as neurotransmitters, endocrine
agents, anti-seizure drugs, steroids
-
Plus other, not yet identified primary therapies that
directly manipulate the biological state and impact
on primary traits.
Note:
biochemical interventions should generally be targeted
at this level, so as to modify an identified or
theorized biological state dysfunction and so impact on
original traits, thereby resolving the "core" problem. A
drug given to a child primarily to "control" unwanted
behaviors (i.e. Ritalin in most cases) will inevitably
lead to other expressions of the primary problem,
causing other unwanted behaviors or compromising the
child’s ability to learn how to act appropriately
without the use of the medication.
BOLD -
Level 2: Original Traits
Original or primary traits are the functional, operating,
core determinants of the individual’s behavior. They are
the biologically based "individual differences" with
regards to each child’s motor, sensory, reasoning, and
affective patterns, etc. These Level 2 original or
primary traits may or may not be modifiable, depending
upon where the child is in the developmental biological
life cycle. The earlier one intervenes with the child,
the more likely that one can modify an original trait.
The earliest possible intervention is important to
increase the chance of modifying any trait.
Original traits, for the purposes of evaluating and
treating communication and learning disorders, can be
represented as strengths or weaknesses in i.e.:
-
Visual acuity
-
Visual/spatial processing
-
Auditory acuity
-
Auditory processing
-
Sensory modulation
-
Motor planning and sequencing
-
Kinesthetic processing
-
Affective processing
-
Cognitive functioning
-
Memory processing
-
etc, etc, etc…
Level 2
Original Trait Modifiers
These modifiers are sensory stimuli from the environment
and all individuals who interact with the child. The
level 2 modifiers include:
-
Parents, siblings, caregivers and peers
-
TV, radio, games etc.
-
All other tactile, auditory, visual, gustatory and
olfactory stimuli
-
Interactions with therapists
The
interactions of the child with all these personal,
interpersonal and sensory/communications factors can
result in Level 3 Learned or Secondary Behaviors. For
most children the Level 1 and 2 modifiers are sufficient
to produce constructive, socially appropriate behaviors
and allow the child to progress appropriately through
the developmental levels. However for children at risk
for a communications or learning disorder these
modifiers can result in more dysfunctional Level 3
Learned Behaviors.
BOLD –
Level 3: Learned or Secondary Behaviors
There are three (3) types of Learned or Secondary
Behaviors which are the direct result of the child’s
Original Traits and the basic interactions with his
caregivers and the environment. They are:
-
The child’s developmental level
-
"Normal" coping behaviors
-
"Abnormal" coping behaviors
It
must be true that, if we were to know the child’s
Biological States, Original Traits, all of their
modifiers, and the developmental level, then all
"abnormal" behaviors will be understood as normal and
predictable given the entire scenario. Unfortunately,
many syndrome diagnoses are made at this Level 3 or
Learned Behaviors level. This can be very misleading,
since many of these "abnormal" behaviors may be caused
by very different combinations of biological states and
original traits and level 1 and 2 modifiers, and require
VERY different intervention strategies to be successful.
Learned
or Secondary Behaviors (and some problems) include:
-
Speech: (pronunciation problems)
-
Language (poor sentence structure, vocabulary, receptive
language, expressive language)
-
Reading
-
Memory
-
Attention (restless, inconsistent, careless, insatiable,
distractable)
-
Impulsivity
-
Socialization: (unusual responses to sensory stimuli,
resistance to change and insistence on routines,
difficulties with typical social interactions,
social and emotional unrelatedness, stereotyped
behavior - routines, rituals and attachment to
objects, lack of eye contact).
-
Fine Motor Skills: (clumsiness, poor pencil grip, poor
letter formation): Impaired fine motor skill,
including dysphasia and apraxia, impaired motor
planning, hypotonia - low muscle tone, soft ears,
double jointed, upper body weakness
Developmental Level and Executive Developmental
Functions:
The
four executive developmental functions also can be seen
as Level 3 or Learned Behaviors. Executive functions are
any behaviors which serve to organize a series of events
over a long period of time, i.e:
-
Prolongation: Holding & evaluating events in working memory
-
Separation & regulation of affect:
Splitting facts from feelings
-
Internalization of language:
Reflection, self-control, will power
-
Reconstitution:
Break events into parts and reassemble into new
ideas
Diminished proficiency in executive functions may
contribute to a communication or learning disorder by
leading to:
-
Deficient self-regulation of behavior, mood, response
-
Impaired ability to organize/plan behavior over time
-
Inability to direct behavior toward the future
-
Diminished social effectiveness and adaptability
Theory
of the Mind Research Addresses Learned Behaviors
In
recent years, research has suggested theory of mind
(TOM) (i.e. the ability to understand the mental states
of the self and others) as an explanation for the
social, cognitive, and communicative impairments of
children with communication and learning disorders
(Baron-Cohen, 1996; Happe, 1995, 1997; Tager-Flusberg &
Sullivan, 1994). See Appendix 3 for a discussion of
"Theory of The Mind and Learned Behaviors."
Level 3
Learned Behavior Modifiers:
The
abnormal behaviors in Level 3 tend to evoke responses
from everyone the child interacts with: parents,
friends, but also society in the form of schools, public
places, legal system, the community at large, etc. Their
responses help modify these Level 3 Learned Behaviors.
In the case of abnormal behaviors inappropriate
intervention will further damage the child’s
functioning. Some inappropriate interventions are:
-
Sole use of drugs to control behavior
-
Isolating the child in a locked facility
-
Restricting the child to a special needs environment and
not including "typical" children
These inappropriate interventions can lead to
Inappropriate Level 4 Derived Behaviors, which can be
even more disruptive.
BOLD -
Level 4: Derived Behaviors
Includes all Complex and Derived Behaviors (which
typically can be more disruptive or dysfunctional than
Level 3 Learned Behaviors) of children in response to
the response they receive from people and institutions
in response to their original traits and learned
behaviors. At this level the behaviors may be so far
removed from the Original Traits and Biological State
that it is most difficult or impossible to assess a
child and implement proper intervention strategies.
Frequently and unfortunately, this is the level that
many syndromes are also evaluated at.
Abnormal behaviors which are observed at this level may
include:
-
Severe head banging, rocking, spinning
-
Constant self-stimulation
-
Physically attacking others by biting, kicking, head
butting, spitting
-
Yelling out inappropriately
-
Constant seeking out of attention by negative behaviors
-
Severe uncontrollable temper tantrums and anger flare
ups
-
Complete social withdrawal and social isolation
-
Lack of development of spoken language
-
Constantly in motion
Research seems to indicate that there is a way to
prevent Derived Behaviors from developing and that is by
placing children with these disorders in "inclusion
environments" in which they can gain the positive social
and communications role modeling of typical peers.
Mesibov (1984) suggests that many children with these
disorders may exhibit social deficits because they have
few friends and limited opportunities to socialize with
peers. Evidence from previous studies demonstrates that
children with these disorders are responsive to social
stimuli. Strain et al. (1979) and McHale (1983) both
found increases in social behavior when peers actively
engaged children with these disorders in social
interaction. Positive social behaviors included sharing
toys, hugging, handholding, verbalizations to maintain
interactions, increases in cooperative play, and
decreases in solitary behavior. These findings emphasize
the positive effects of social interaction through peer
engagement on the behavior of individuals with these
disorders.
Research specifically on inclusion with special
populations has been encouraging (Wang and Baker, 1986;
Strain & Kerr, 1981; Carlberg & Kavale, 1980). Studies
show gains in socialization with a total inclusion model
( Hoyson, Jamieson, & Strain, 1984). There are positive
benefits in both social and cognitive development (Hoyson,
Jamieson & Strain, 1984; Harris, Handleman, Kristoff,
Bass, & Gordon, 1990). There are also positive benefits
in the social interaction areas (Roeyers, 1996). |
