• Asperger’s Disorder Qualitative impairment in social interaction. Restricted repetitive and stereotyped patterns
of behavior, interests, and activities. Significant impairment in social, occupational
or other important areas of functioning. No cognitive impairment. The qualitative impairment in communication
is not met as there is no significant general delay in language.

What is PDD or Autism Spectrum Disorder?
What is PDD or Autism Spectrum Disorder?
• Autism Society of America (2000)• Autism is a complex developmental
disability that typically appears during the first three years of life. The result of a neurological disorder that affects the functioning of the brain.
• Autism is four times more prevalent in boys than girls and knows no racial, ethnic, or social boundaries. Family income, lifestyle and educational levels do not affect the chance of autism’s occurrence.
Definition cont…Definition cont…
• Autism interferes with normal development of the brain in the areas of social interaction and communication skills. Children and adults typically have difficulties in verbal and non-verbal communication, social interactions and leisure or play activities.
• The disorder makes it hard for them to communicate with others and relate to the outside world. They may exhibit repeated body movements, unusual responses to people or attachments to objects, and they may resist changes in routines.
PrevalencePrevalence
• Over one half million people in the U.S. today have some form of autism. Its prevalence rate now places it as the third most common developmental disability more common than Down syndrome.
• ASD occurs in 1 of every 200 – 250 births. Some estimates are now 1 of every 166 births.

More questions about the trends…More questions about the trends…
• Are we over identifying ? No, there is evidence we are still under identifying in early years..
• Are other states finding the same rates ? Only one state is higher (Oregon) than Minnesota
• Will the ASD Child Count continue to increase? Analysis of MDE Child Count and NIH data predicts continued increase.
• What forecasts or estimates can be made ? 1/500 to 1/166 births (NIH, 2004 and CDC, 2006) Increase of secondary-age students 2x by 2010

Number of Individuals
Local PrevalenceLocal Prevalence
• There has been a 400% increase in students identified with Autism in the last four years. The students range from “high functioning” to
more classical Autism. Anecdotal evidence suggests recent increases
in “high functioning” students.
Theories of CausationTheories of Causation
• Genetic Four times more males than females. Does tend to occur more frequently in families.
• Immunizations Research indicates no connection between
immunizations and Autism. Studies that implied a connection were methodologically flawed.
• Environment Likely that there is an environmental trigger or
influence.
Specific Characteristics of ASD
Specific Characteristics of ASD
Skills of Individuals with ASD Vary from Individual to
Individual
Skills of Individuals with ASD Vary from Individual to
Individual• Some individuals have average intelligence but a
delay in social skills.
• Some individuals may be significantly delayed in all areas with no verbal skills.
• Some individuals may be verbal but exhibit delays in communication as well as having difficulties with social interaction and a wide range of interests.
• The range of areas of concerns within each of these disorders varies from mild to severe depending on the individual. No two individuals are alike with their range of abilities!
ASD is a Neurological Disorder
ASD is a Neurological Disorder
• It is a disorder of the brain• Involves a number of brain functions.• Research has shown that the brains of individuals with
ASD are formed differently from other individuals.• Brain dysfunction involves abnormalities in
interpreting facial expressions, organizing sequences, planning (executive function), compulsivity and problems in language (Travis Thompson, Making Sense of Autism 2007)
ASD is a lifelong disorder but not progressive; it does not get worse over time.
Brain Structure FindingsBrain Structure Findings
• Face Processing & Gaze Fixation in Autism• Deficits in attention, learning & discrimination of human faces,• Disproportionate attention to the mouth versus eyes• More attention to specific details rather than facial configuration• Social brain function in autism (Simon Baron-Cohen et al 1999)• Assigning mental states to eyes-only facial stimuli usually activates
amygdala, cingulate and frontal brain regions• NOT among individuals with high functioning ASDs
Brain Structure FindingsBrain Structure Findings
• Amygdala is involved in Gaze Fixation & Understanding Facial Emotions
• Amygdala damage impairs recognition of emotional facial expressions
• People who have amygdala tumors don’t look others in the eye when talking to them
• Brain Imaging: Amygdala is typically activated by emotional facial expressions, especially eyes
Brain Structure FindingsBrain Structure Findings
• Abnormalities in Brain Areas Related to Obsessive Compulsive Disorder
• Prefrontal cortex does not process information properly, which is required for problem-solving, flexibility and planning
• Dysfunction in brain areas that cause symptoms of Obsessive Compulsive Disorder (OCD) lead to rigidity and intolerance for changes in routines.
Consequences of Brain Dysfunction in ASDs
Consequences of Brain Dysfunction in ASDs
• Unable to understand facial expressions, especially emotions
• Unable to grasp gestures, their meaning and often very difficult to imitate gestures
• Unable to anticipate social consequences of their actions
Speech/Language DysfunctionSpeech/Language Dysfunction
• The two primary speech areas in the brain do not work well in coordination, i.e. Broca’s and Wernicke’s
• As a result, very slow processing of speech sounds compared with other sounds
• Even in youngsters with large vocabularies, they may have difficult processing speech of other people
Behavior is Not IntentionalBehavior is Not Intentional
• People with ASDs and related disabilities don’t wake up in the morning thinking of ways to drive their parents & teachers to the brink.
• They are doing the best they can to create control over a world that seems disorderly, chaotic and impossible to understand
Early Behavioral InterventionEarly Behavioral Intervention
• Dysfunctional brain areas in children with ASD contain more tightly packed immature brain cells but very few synapses.
• Fewer synapses may lead to excessive neural cell pruning
• Early intervention promotes brain development (synaptic connections)
• Early intervention prevents loss of brain function that will occur otherwise
• Research has consistently demonstrated that intensive behavioral intervention is superior to other approaches: ABA, DTT, PECS, and PRT have a relatively strong evidence (National Research Council, 2001; Rogers, 1998).
Impairments in Social Interaction
Impairments in Social Interaction
• Limited use joint attention and limited use of facial expressions directed towards others.
• Does not show or bring things to others to indicate an interest in activities.
• Demonstrates difficulty in relating to people, objects, and events.
• Demonstrates a gross impairment in the ability to make friends.
• Significant vulnerability and safety issues due to social naiveté.
• May appear to prefer isolated or solitary activities.
• Misinterprets others’ behaviors and social cues.• Is unresponsive.

Communication• Does not use a finger to point or request.• Uses others’ hand or body as a tool.• Shows lack of spontaneous interaction or lack of varied
imaginative play.• Has absence or delay of spoken language.• Has limited understanding of non-verbal communication skills
such as gestures, facial expression or tone of voice.• Demonstrates odd production of speech, including intonation,
volume, rhythm or rate.• Demonstrates repetitive or idiosyncratic language or inability
to initiate or maintain a conversation when speech is present.• Has limited imitation of action or sounds.• Repeats or echoes words or phrases.• Does not seem to understand word meaning.• Has limited eye contact.

Educational Criteria vs. Medical Diagnosis
Educational Criteria vs. Medical Diagnosis
Educational Criteria
• Meet specific behavioral indicators on a checklist. AND
• Demonstrate educational need.
• Evaluation includes parent information and information from other environments and individuals.
Medical/Clinical Criteria
• Meet specific behavioral indicators on a checklist. DSM-IV
• Often based upon parent report and brief interaction with child.
Educational Criteria vs. Medical Diagnosis
Educational Criteria vs. Medical Diagnosis
• Having a medical diagnosis of Autism does not automatically qualify a student for special education service.
• Educational evaluation must document evidence of a disability AND educational need.
Educational Needs of Learners with Autism Spectrum DisordersEducational Needs of Learners
with Autism Spectrum Disorders
• Students with ASD must learn: The ability to attend to elements of the
environment The ability to imitate others The ability to comprehend and use language The ability to play appropriately with toys The ability to interact socially with peers The ability to learn self-regulation skills The ability to organize and plan activities
ASD Learner needs include…ASD Learner needs include…
• A highly supportive teaching environment with opportunities to generalize skills to typical settings
• Structured and predictable environments
• A functional approach to problem behaviors
• Transition planning as the students advances in their education
Social Skills vs. CurriculumSocial Skills vs. Curriculum
• Social skills are just as, and often more, important than math, reading or other academic skills.
• Our job is to provide students with the skills to get along in society.
• It takes months and years of consistent programming for children with ASD to learn these skills.
Classroom StrategiesClassroom Strategies
• Be direct, don’t use figurative language.Simple concrete directions

SummarySummary
• Students with Autism are complex and their behavior is often confusing.
• However…… Behavior is lawful Positive alternative behaviors can be taught There are no magical strategies Students with Autism learn in much the same
manner as other children.
