The current accepted medical terminology for Autism is Autism Spectrum Disorder (ASD). The use of “Spectrum” accurately describes the wide range of
symptoms, levels of impairment or disabilities and their varying degree of
severity. As some children can be only mildly impaired
by their symptoms, others can suffer from severe disability.
In March 2012, the Centers for Disease
Control and Prevention issued their ADDM autism prevalence report. The
report concluded that the ASD
affects 1 in every 88 children born in the United States, with a slightly
higher rate for males, almost 1 in 54.
With occurrence rates that high, almost
everyone knows someone impacted by ASD.
Therefore, it is important we all educate ourselves about this common and
complex issue.
What
are the symptoms of ASD?
As mentioned before
symptomology and severity can vary widely from one child to the next. Generally accepted indicators can include:
- Lack of or delay in spoken language
- Repetitive
use of language and/or motor mannerisms (e.g., hand-flapping, twirling
objects)
- Little or
no eye contact
- Lack of
interest in peer relationships
- Lack of
spontaneous or make-believe play
- Persistent
fixation on parts of objects
Parents, family members or others
in close connection with the child should bring any concerns about the
potential for ASD in the child to the attention of their health care provider
immediately. Early intervention can
reduce or prevent the more severe disabilities associated with ASD and may also
improve your child's IQ, language, and everyday functional skills, also called
adaptive behavior.
How is ASD
diagnosed?
Whether it is the result of an
evaluation specifically initiated by a parent or a routine developmental
screening during well-child checkups with a health care provider, children who
show some developmental problems are referred for additional evaluation.
Initial Screening
A well-child
checkup should include a developmental screening test, with specific ASD
screening at 18 and 24 months as recommended by the American Academy of
Pediatrics. A parent’s
own experiences and concerns about the child's development are a very important
part in the screening process. Notes
about the child's development, even family videos, photos, and baby albums help
to document behavioral timelines and developmental milestones are all useful to
the health care provider in the evaluation of the child. The initial screening instruments used by the
doctor for toddlers or preschoolers may consist of:
- Checklist of Autism in Toddlers (CHAT)
- Modified Checklist for Autism in Toddlers
(M-CHAT)
- Screening Tool for Autism in Two-Year-Olds
(STAT)
- Social Communication Questionnaire (SCQ)
- Communication and Symbolic Behavior Scales
(CSBS).
To screen
for mild ASD or Asperger syndrome in older children, the doctor may rely on
different screening instruments, such as:
- Autism Spectrum Screening Questionnaire (ASSQ)
- Australian Scale for Asperger's Syndrome (ASAS)
- Childhood Asperger Syndrome Test (CAST).
Comprehensive Diagnostic
Evaluation
The next
step in diagnosing ASD involves a thorough evaluation to rule out other causes
or conditions that could be responsible for the symptoms. This stage utilizes a team of health care professionals
that encompasses a wide range of specialties: psychology, neurology,
psychiatry, speech therapy. The
evaluation at a minimum should include the assessment of cognitive and language
levels, and age-appropriate skills needed to complete daily activities
independently. Due to complexity in
nature of ASD and the possibility of other accompanying illnesses more
comprehensive testing may be appropriate:
hearing testing, screening for lead poisoning, brain imaging, genetic
testing, and in-depth memory, problem-solving, and language testing.
Some helpful resources on ASD
screening include the Center for Disease Control and Prevention's General
Developmental Screening tools and ASD Specific Screening tools on their website.
How is ASD treated?
Once a child is diagnosed as
having ASD, discussions begin on
treatment options. As varied and
individual as each child, so are the options.
Nonmedical interventions include behavioral and
educational approaches as well as focuses on sensory response and communication.
- Applied Behavior Analysis (ABA) is a treatment plan that
includes verbal behavior and pivotal response training interventions centered
around shaping and reinforcing new behaviors, such as learning to speak and
play, and reducing undesirable ones.
- Developmental,
Individual Difference, Relationship-based (DIR)/Floortime Model aims to build healthy
and meaningful relationships and abilities by following the natural
emotions and interests of the child.
- TEACCH (Treatment and Education of Autistic and related
Communication handicapped Children) emphasizes
adapting the child’s physical environment and using visual cues.
- Interpersonal Synchrony targets social development and imitation
skills, and focuses on teaching children how to establish and maintain
engagement with others.
Medical
interventions, in children ages 5 to 16 who have ASD, with medications such as antipsychotics,
antidepressants, and stimulants
have been known to help reduce symptoms such as irritability
which can often translate into aggression, self-harming acts, or temper
tantrums.
Biomedical treatments include modifications in diet such as the gluten-free/casein-free
diet, addressing food sensitivities, addition of vitamins and minerals
supplements, immune system regulations and others.
