What we know about DS





Prevalence 1/700 live births in USA
Most children have delayed development
Wide range of abilities from mild to severe
For most, level ability can not be predicted
at birth
Early intervention makes a difference
Talk and Total Communication
Speech and Language
Development



Spoken language delayed for most children with
DS – first words 24-48 months
Communication skills are poor
Vocabulary is delayed


Grammar


Understanding ahead of expression
Typically use only key words
Speech


Poor intelligibility, means difficult to understand
If child can not be understood, reluctant to speak

Life Expectancies
 In
1929 life expectancy was 9 years
 In 1983 life expectancy was age 25 years
 In 1997 life expectancy has risen to age
49 years
 Current estimates indicates life
expectancy is now 55 years
 Due
to improvements in medical care and
advances in surgery.
Talk and Total Communication
Life Expectancies
 Alzheimer
disease: A problem after age
20 years
 Occurrence
of senile plaques and
neurofibrillary tangles in DS match brain
lesions of Alzheimer disease
Talk and Total Communication
Aging
 Decline
in cognition
 No decline in language skills up to
middle age
 50+ years may see decline in skills of
speech, pragmatics, and receptive
vocabulary (especially for those with
dementia

Down syndrome
Perspective on Dual Diagnosis
Talk and Total Communication
Autistic Spectrum Disorder
in Down Syndrome
Prevalence of DS & ASD ~5%
Impairments in: Reciprocal social and language
function. No symbolic or imitative play
Restricted interests: Repetitive or ritualistic
behaviors.
DSM-IV / ICD-9 criteria
Autistic Disorder (onset <3 yr.)
Pervasive Developmental Disorder-NOS
Childhood Disintegrative Disorder (late-onset)
Talk and Total Communication
Autistic Spectrum Disorder in
Down syndrome
 Meeting
DSM-IV criteria exhibit a
spectrum of social-skill impairments
 Concordant with low cognitive level
social delay & adaptive impairment
 Discordant with cognitive level
social withdrawal – apathy
social indifference – aloofness
social avoidance - anxiety
Talk and Total Communication
DS-ASD
Early Onset
Poor development, gradual onset of atypical
behaviors (gaze, stereotypy)
**Infantile spasms more frequent in this group
Characteristic EEG pattern
Severe neuro-motor impairments, feedingswallowing problems
Talk and Total Communication
DS-ASD
Late Onset
Typical early development followed by subacute
behavioral deterioration and regression (speech,
cognitive, social skills)
Motor skills unchanged
Seizures or EEG abnormality not typically
observed
Autoimmune? Leukemia ChemoTx ? None of the
above ?
Talk and Total Communication
Appears Like Autism..but Isn’t
Stereotypic movements - unusual
sensory responding and inattention
Obsessive compulsive disorder –
perseveration & rituals
Language, Play, and Social relatedness
are relatively preserved

 Replacement skills
 Consequence strategies
Talk and Total Communication
Setting events
 Changes
in events that may influence
behaviors
 Allergies,
sleep disorder, illnesses
 Intervention:
record setting and behavior;
e.g., notebook at home to let school know
child did not have a restful sleep
 Sharing with other caregivers setting event
 Adjust demands on child, like at school, and
increase highly preferred activities.
Talk and Total Communication
Communication in
Infants and Toddlers
Early Language Development
 Early
intervention is key for children with
DS
 Parental education
 Input
should match child’s comprehension
 Sensory
stimulation
 Monitor hearing
 Social skills development- i.e. peekaboo,
turn-taking toys
 Consider total communication
 Daily routines to teach concepts
Talk and Total Communication
Useful tools/techniques





Visual cues
 Because of possible hearing loss, supplement
verbal communication with visual cues, i.e.
gestures
Pacing boards
 Multi-word stages – 1 dot per word
 Increase MLU – 1 dot per morpheme or syntactic
element
Carrier phrases: to promote multi-word phrases
Expansion of single word utterances to multi-word
utterances
Mirrors to promote self-awareness
Talk and Total Communication
Vocabulary/Semantics
 Expand
vocabulary
 Use whole language activities – i.e.
daily activities
 Increase length of
utterances/phrases
 Use play-based activities -
Talk and Total Communication
Selecting First Words
 Functional
words, child interest, child directed
 Follow normal development, child skill level
 Items should be reinforcing
 Food: cookies, juice, chips
 Toys: bouncing ball, action, sounds
 Motor: tickle, bouncing on
trampoline, wiggle
 Sensory: music, hot/cold, down
 Social: bye, finished, please
Talk and Total Communication
Intervention
 Scaffolding
and Generalization
 Milieu language teaching – naturalistic
 Modeling
 Prompting
 Speech and Language recasts- child’s
utterance is expanded into a
grammatically form
Talk and Total Communication
Recasting speech and language
 Speech
 Adult
utterances that add only sound information
to the child’s oral output
For example, child says, “This is a -at.”
 Adult says, “Yes cat.”
 No new grammar information is added.

 Grammar
 Adult
utterances that add grammar or semantic
information to the child’s oral output
For example, child says, “She seep.”
 Adult says, “Yes, she sleeps.” (adding speech and correct
verb ending.
 New grammar information is added

Talk and Total Communication
Use of verbal routines
 Verbal
routines are useful when child
acquires common utterance in discourse
situations
For
instance, child says, “I want ___,” “I
see ___,” or even “No more ___,” and
“Where ___?”
Talk and Total Communication
Spontaneous speech activities




Action pictures
 Child describes actions – adult expands
 Frequent repeat same pictures
Thematic activities
 Literacy kits
Rehearsal and modeling
 Play situation to teach social interaction – little
people
 Pretend going to park to play on swings
Story starters


iPad story starter aps
Cloze procedure/choices

Model choice during requesting – child makes choice
between two toys, food, pictures

The Role of Signing in Early
Communication
Signing is Like a Picture
Iconic
Shapes are visually
like the concept
 car
 eat
 ball
 cat
 on
 girl
Abstract or less of a
relationship
 play
 more
 please
 no, yes
Talk and Total Communication
Intervention
 AAC
sign language
 Some
children do not acquire first word
until 6 years old
 Sign can be used as supplement, as verbal
communication skills are still minimal
 a Sign can be a primary means of
communication when necessary
 Sign can be an additional support to
decrease frustration because receptive
skills better than expressive
Talk and Total Communication
Children with Down syndrome
 Overall
slower developing motor areas
 Typically hypotonia, flaccid motor
skills
 Data suggest myelination along motor
strip is delayed in development
 This could account for the delays in
expressive words.
Talk and Total Communication
Children w/ DS: Comprehension
 Comprehension
in auditory cortex develops
earlier than production in motor cortex
 Comprehension may occur in both left and
right hemispheres
 Child has early understanding of language,
similar to typical child
 Child may have a need to communicate,
similar to typical child, but no means
 Signing is a means for early communication
Talk and Total Communication
Hypotonia
 Complicates
expressive language, nearly
all children with Down syndrome have
hypotonia
 Demonstrated in poor strengthening of
large and fine motor skills
 Walking, writing, drawing are affected
 Tongue, lip, jaw movements also affected
 Speech is subsequently impaired
Talk and Total Communication
Oral Motor Problems
 40%
or more of children with Down syndrome
have moderate-to-severe oral motor problems
 Oral motor problems impede speech production
and speech intelligibility
 Sign can be used to augment poor speech
intelligibility during social communication
exchanges
Talk and Total Communication
We introduce signs:
 At
the same time we introduce words usually around 6 - 8 months
 Use of signs comes before speech
production
 Sign while communicating to child

e.g. “Dog - dog” I see dog” “See dog!”
Talk and Total Communication
We introduce signs:
 Introduce
Iconic signs first
 Stimulation (comprehension) first
 Later on, we shape the sign by taking
child’s hand while stimulating
 Remember to use SPEECH
 Stimulate, shape hands, wait for child
to produce it
 Reinforce all attempts
Talk and Total Communication
Does signs prevent talking later on?
 All
data show sign does not delay speech
 Our own empirical data show signs drop
off when a child is ready to talk.
 Wisconsin research suggests children who
are early signers have better speech and
language skills later on.
 Even if child has severe oral motor
problems, signing can help in speech
intelligibility

 DS w/out and TD Artic produced
similar errors (substitutions &
distortions)
Improving Intelligibility
 Keep
in mind: pitch, rate, oral-motor abilities,
working memory
 Apraxia
 Articulation test to obtain profile of errors
 Use of “typical” intervention
 Focus on syllable structure
 Phonological Awareness: books
 Phonological Processes
Talk and Total Communication
Suggestions for Stimulating Language
 Follow
the child’ lead. Talk about what s/he is
doing using single words or short phrases.
 Speak slightly slower and a little louder
 Sit face-to-face while playing and talking
 Hold objects and toys near your mouth
 Talk about what you are doing while doing it
 Think out-loud. Let child hear your thoughts
 Be aware of “over talking.” Leave some silence
 Look for opportunities to emphasize new
vocabulary and stimulate language throughout
the day
Talk and Total Communication
Suggestions for Stimulating Language
 Use
open-ended questions (e.g., “what do
you want to play?”) or choice questions (e.g.,
“Do you want blocks or cars?).
 Have fun with language!
 Introduce new words, short poems, finger
play, and songs
 Make book reading and stories a daily
routine
 Respond to vocalizations in a meaningful
way
Talk and Total Communication
Treatment Strategies:

Reading in preschool children
 Buckley
(1985) reported on Sarah who read at age
3 years.
 Buckley (1995) reports on Digby who read at 25
months of age, long before he spoke his first
word. Emma and Daniel read at 28 months, Zoe
at 3 years 5 months, and Jamie at 3 years.
 Buckley also reported that Daniel used his
reading to improve his expressive language
skills.
Talk and Total Communication
What is Known
 Home
environment has a dramatic
influence on literacy.
 Expectations by parents is important et
al., 1991).
 Through reading, children w/ DS learn
concepts that improve oral and written
language (Buckley, 1995; Layton, 2000).
 Children w/ DS can learn to read early
(Buckley, 1995; Layton, 2000; Lorenz et
al., 1985).

In China, because of the one child per family policy,
women usually choose to have their child between 25
and 27 years of age. Pregnant women of advanced
maternal age are rare.
Therefore, the birth prevalence of Down syndrome in
China is very low, less than 1/1000 live births.
*Estimated number of individuals with Down
Syndrome is 1,623,559

Meetings with other families at a special school had been
arranged two days of our trip. When I informed them that I
had a prenatal diagnoses of DS and a heart defect with
Caroline, you could see the shock on everyone of their
faces. China does not offer anything as far as services, public
school, etc. like we experience here. They do not take their
kids out in public. Only one of the families that we talked to
actually had a diagnosis at birth, the rest found out months
and up to 2 years later, after realizing themselves there were
developmental delays. Once diagnosed, most did not tell
their extended family that they had a child with
DS. Unfortunately, the evolution of China is decades behind
our way of thinking that every child deserves every
opportunity.
