Pervasive Developmental Disorder- Not Otherwise Specified (PDD-NOS)

To best understand Pervasive Developmental Disorder- Not Otherwise Specified, it is important to first understand what it is not. Often times, PDD-NOS is incorrectly defined as PDD, which is not a diagnosis in itself. PDD refers to the broader spectrum of disorders, which Autism, for example, falls under (Autism Program, 2009).

Thus, PDD-NOS refers to any disorder within the Autistic Spectrum which does not fit the description of one of the other disorders covered within the spectrum.

In addition, it should also be noted that PDD-NOS is also defined as the following:
1. Atypical Personality Develoment
2. Atypical Pervasive Developmental Disorder
3. Atypical Autism
These different forms of PDD-NOS are included in the DSM-IV to include instances of impaired social relationships/communication or abnormal interests/behavioral patterns that do not fit into the specific diagnoses of Autism or PDD.

General Statistics of Autistic Spectrum Disorders

The following graph charts the percentages of specific disorders within the Autistic Spectrum. These results were taken from a study performed by the Interactive Autism Network (IAN), studying young men and women, living with their families, with disorders that fall within the Autistic Spectrum.

Professional Approach to Individuals with Asperger's Syndrome

"The treatments of an adult and a child presenting Asperger's Syndrome illustrate the bridging from their nonhuman world to the world of feelings and people"

(Topel & Lachmann, 2008, p. 602).

The treatment of an individual with Asperger's Syndrome often takes after the idea that Asperger's Syndrome is likely a result of neurological deficiencies (Topel & Lachmann, 2008). Essentially, researchers believe that the onset of Asperger's Syndrome begins as a result of a failure or disturbance in the neural network of the brain. These neural issues are what results in the various different social difficulties that individuals with Asperger's Syndrome experience.

Thus, in order to best treat the individual, counselors and doctors often aim for behavior-focused therapy. Any deficits in the area of social-cognitive functioning can be addressed through the application of cognitive-behavioral therapy (CBT). This version of therapy will help address both issues of cognitive functioning as well as behavioral issues (Topel & Lachmann, 2008).

When treating or counseling an individual with Asperger's Syndrome, it is important to note that they may suffer from a range of other symptoms in addition to the primary symptoms of the disorder. These other symptoms may include the following:

1. Attention Deficit Hyperactivity Disorder

2. General Anxiety Disorder and/or Depression

3. Obsessive-Compulsive Disorder

4. Non-Verbal Learning Disorder

5. Social Anxiety Disorder

Asperger's Syndrome: Symptoms and Diagnosis

Image from: http://cherished79.files.wordpress.com/2007/06/aspergerssyndrome.jpg

Asperger's Syndrome is similar in some senses to Autism, but is often referred to as high-IQ Autism. Essentially, this means that while individuals with Asperger's Syndrome suffer from impairment in social interactions, their overall ability of cognitive and communicative functioning is not as severely impaired (Miller & Ozonoff, 2000).

Symptoms of Asperger's Syndrome:

1. Difficulty with social skills/cues (reading others' body languages and maintaining conversations)

2. May seem to lack empathy

3. Flat tone of speech, regardless of the context of conversation. In addition, there is often a difficulty understanding differences in the pitch or tone of others when speaking.

4. Heightened sensitivity to either sound, taste, touch, sight, or smell.

5. Preoccupation with only a few specific interests in which the individual is highly knowledgable of.

6. May have a very formal method of speaking (for instance, the child may use the word 'summon' in place of the word 'call')

7. Unusual facial expressions and/or body postures.

Above listed information taken from: (Miller & Ozonoff, 2000)

In order for a child to be diagnosed with Asperger's Syndrome, he or she must display two or more of the above symptoms and show difficulties with social situations. Additionally, in comparison to Autism, a child with Asperger's Syndrome will usually tend to have more normal cognitive and communicative development (Miller & Ozonoff, 2000).

Professional and Ethical Approach to Autism

Though symptoms of Autism can range anywhere from moderate to severe, it is important to keep in mind that it is not a fatal disorder. Individuals suffering from Autism can still lead fairly normal lives.

As professionals, we are called to work with both the individual with the disorder as well as his or her family. When working with an individual who suffers from Autism, it is important to note to reinforce social behavior training in addition to any exercises to increase cognitive functioning. A social worker should work closely with any teachers, counselors, and/or speech therapists to ensure that the individual suffering from Autism receives the best care possible.
Most importantly though, it is essential to reinforce ideals of hope and perseverence in the client.

The following, is a video from a high school graduation where the speaker (class Saluditorian), is a young man suffering from Autism. If anything, this serves as an inspiration that even someone diagnosed with rather severe Autism can accomplish great things.

Autism: Diagnosis and Symptoms

Autism is defined as a cognitive developmental disorder that tends to emerge within the first three years of a child's life (PsychNet, 2003). This disorder is then defined by specific symptoms in the following categories:

1. Language

2. Social Skills

3. Behavior

Though research has been done regarding the onset of Autism, reserachers are still unaware of the exact causes of the disorder. The only evidence that research has shown, is that Autism is likely brought about through a combination of an individual's genetics (hereditary traits) and the environment surrounding that individual (Autism Fact Sheet, 2009).

In order for an individual to be diagnosed with Autism, an individual needs to fall into several different criterion, including the following:



I. Impaired Social Interaction

a. Non-verbal behaviors and communication

b. Lack of close friends/lack of interest in friendship

c. Limited interests or pleasures

d. Limited social/emotional responses (inappropriate responses to situations)



II. Impaired Communication

a. Slow or impaired vocal speech without any compensation

b. Limited ability to begin/sustain conversation with others

c. Repetitive, stereotyped, or non-sensical language

d. Absence of imaginative, imitative, or make-believe play



III. Repetitive or Restricted Activities and Behaviors

a. Obsessive preoccupation over abnormal interests (such as tapping or spinning an object)

b. Rigid schedule of routines and/or rituals that serve little purpose or function

c. Repetitive physical movements such as waving or flapping of hands

d. Persistent interest in the makeup or parts of certain objects

Introduction to the Autistic Spectrum

In order to best understand the Autistic Spectrum, it is important to understand which disorders are included within the autistic spectrum.
According to the Diagnostic and Statistical Manual (DSM) edition IV, the Autistic Spectrum currently includes the following disorders:
I. Autistic Disorder
II. Asperger Syndrome
III. Pervasive Developmental Disorder; Not Otherwise Specified (NOS)

Some Health Professionals will also include the following two disorders into this category as well:
I. Childhood Disintegrative Disorder
II. Rett Syndrome
