Objectives
1.
Conceptualize the clinical
importance of autistic symptoms
on a spectrum.
2. Understand the discrete parts of
the autistic spectrum.
3. Pinpoint the differences of
treatment along the spectrum.
4. Appreciate the flaws in the
concept of a spectrum.
History of DSM and Autism
• 1968: DSM II used the label autism to describe
childhood schizophrenia.
• 1980: DSM III included Autism as Infantile
Autism.
• 1994: DSM IV introduced PDD with 5
subtypes.
•
Types
of
PDD
DSM IV labels basically historical labels.
• Usefulness and connection of labels were
questioned.
• Coincided with a new clinical awareness of
ASD.
• Triggered the “Asperger’s awakening.”

Rhett’s Syndrome
• 1966 Andreas Rhett published reports of girls with
similar symptoms.
• 1983 Bengt Hagberg introduced Rhett’s to Annals
of Neurology.
• 1999 Ruthie Amir discovered MECP2 X- linked
dominant disorder.
• Methyl Cytosine Binding Protein dysregulation.
Rhett’s Syndrome
• Cerebroatrophic Hyperammoneia starts at 6
to 18 months of age.
• Hand wringing, washing/clapping
movements, head growth stops.
• Prone to apnea/hyperventilation.
• Limited awareness, seizures and motor loss.
Childhood Disintegrative Disorder
(CDD)
• 1908 Theodor Heller described dementia
infantilis marked by psychosis.
• After 2 years normal development abrupt
onset of ASD in severe form and loss of motor
skills.
• Rare cause of ASD.

Kanner’s Autism
• 1943 paper Autistic Disturbances of Affective
Contact describing 11 children.
• 1930 to 1959 directed Johns Hopkins Child
Psychiatry.
• 1960’s to 1970’s oversaw and edited Journal of
Autism.
Classic Autism
• Noticeable social problems at 1 year of age.
• Plateau or regression at 10 to 30 months.
• Core symptoms: social skills, communication,
restricted interests.
• Subsequent intellectual, sensory and motor
disabilities.
• Variety of behavioral problems.
PDD NOS
• Atypical Autism doesn’t meet all three categories.
• Clear causative factor (genetic, sensory, medical).
• Later age of onset.
• Milder (IQ, motor, sensory) than Classic Autism.
•
Aspergers Syndrome
• 1944 Autistic Psychopaths in Childhood
described four “little professors” with mild
ASD symptoms.
• 1981 Lorna Wing added AS to ASD.
• 1991 Uta Frith translated original paper
adding much to concept.

Asperger Explosion
• ASD without Intellectual disabilities.
• Replaced A Cluster personality disorders.
• Represents social impairments.
• High Function Autism (HFA) intelligent and odd.
• Easiest to assess, study and treat.
Epidemic of Autism
• Study found a 230% increase in cases of
Autism in CA over the past 10 years.
• School systems are providing comprehensive
behavioral services for Autism in early
childhood.

Broader Autistic Phenotype
• Broader Autistic Phenotype is marked by
personality qualities seen in families.
• Revolves around Asperser's Syndrome.
• Aloof, rigid, anxious, social isolated, restricted
nonverbal skills.
• Deficits in Executive Functions.

Treatment Spectrum
• Rarest ASD is genetic/metabolic/medical,
most severe (least responsive to treatment).
• Mildest ASD is most common and least
medical (most responsive to treatment).
• In the middle is most typical/classic.
Behavioral Treatments
• Behavioral treatments are always the first step
prior to any medication.
• The three pillars: communication, transitional
programs, sensory integration.
• Behavioral research has focused mainly on
Intensive Behavioral Modification ABA and
communication programs.
Communication
• Programming addresses one of the core
deficits of Autism.
• Most training focuses in on picture or
symbolic language.
• Training is intensive, time consuming and
repetitive.
• Some research completed: TEACCH, PECS,
Lovaas.
Social Skills Training
• Social skills training utilizes variety of techniques
breaking down complex social behaviors.
• Communication training benefits day to day
functioning.
• Includes social cues, transition rituals, transition
objects, and picture cards.
Sensory Integration
• Uses a wide variety of stimulation—vestibular,
skin, deep touch, massage—to enrich and
calm.
• May involve cerebellar pathways and
ACH/serotonin stimulation to the brain.
• Requires training, equipment and usually daily
stimulation.
• Little research.
Benefits of Early Interventions
• Jacobson, et. al, 1998, showed a substantial
savings with Early Behavioral Interventions
(EBI).
• Treatment costs are $30,000 to $40,000 and
require 3 years of training.
• 30% of patients achieve independent living.
ASD in Remission
• Children getting early intensive treatments
can lose many symptoms of ASD.
• Move into average range in many areas.
• Stereotypy, odd movements and social
problems continue.
• More mild more likely.
ASD in DSM 5
• Little change to original Autism criteria.
• Three levels of severity based on social,
communication, and rituals/repetitions.
• Added language on supports needed.
• All historical labels lost.
Social Communication Disorder
• Impairment of pragmatics, social uses of verbal
and nonverbal communication and social
relationships.
• Functional limitations in effective
communication, social participation, academic
achievement, or occupational performance,
alone or in any combination.
SCD
• Rule out Autism Spectrum Disorder (ASD).
• Symptoms must be present in early
childhood (but may not become fully
manifest until social demands exceed
limited capacities).
ASD Spectrum
• Consistent with clinical practice.
• Level of severity of symptoms, medical, behavioral
problems and IQ loss.
• DSM V criteria based on Kanner’s Autism.
• Devoid of genetic/medical causes, qualifiers for IQ,
Behavioral or psychiatric symptoms.
• No remission concept.
