Presentation
PRESENTATION Autism and the pervasive developmental disorders Autism and related pervasive developmental disorders (PDDs), sometimes called the Autism Spectrum Disorders, refer to a family of early onset and lifelong disruptions of socialization variably [scielo.br]
Furthermore, clinical presentation of PDD-NOS may resemble presenting symptoms in high functioning autism, Asperger’s disorder, reactive attachment disorder, and psychotic disorders, and the differential diagnosis may be highly complicated. [intechopen.com]
Health professionals readily refer non-verbal children to rule out hearing impairment, but it is possible that verbal children presenting with milder degrees of autism were overlooked or not referred. [sajch.org.za]

Falling
Previous analysis of data from 505 preschool children with disordered communication, falling into the a priori categories of Pervasive Developmental Disorder (PDD), Developmental Language Disorder, and Nonautistic Low IQ, showed that PDD is statistically [tandfonline.com]
Treatment for autism spectrum disorders The emphasis falls on early and intense educational interventions. Most treatment is behavior-based and highly structured. [discoverymood.com]
But the term PDD-NOS has become obsolete too as it now falls under autism spectrum disorder. Not surprisingly, there is a considerable amount of confusion around the term PDD. [appliedbehavioranalysisedu.org]
A child who receives a diagnosis of PDD-NOS usually falls into one of the following categories(2): The child is high functioning, like a person with Asperger syndrome (now considered a part of ASD), but is experiencing mild learning issues and/or language [brainbalancecenters.com]
Pervasive Developmental Disorder experience significant impairments in general intellect and overall development, the media has been most interested in the small group of perhaps fifteen to twenty percent of children with Pervasive Developmental Disorders falling [samgoldstein.com]

Weakness
People with Autism are known for their weaknesses in abstract thinking, social cognition, and communication. [courses.lumenlearning.com]
A good knowledge of the child’s strengths, weaknesses, interaction preferences and early signs of distress. Social stories to help teach the child how to act in given situations. Use of visual cues to describe the routine. [childdevelopment.com.au]
Diagnostic agreement for PDD-NOS is generally considered to be weak (Tanguay, 2004). [intechopen.com]
They perform cognitive assessments, provide feedback to the person and family about cognitive strengths and weaknesses, and help guide future learning, career and lifestyle choices. [mja.com.au]
The child’s strengths and weaknesses must be profiled to assist in designing appropriate intervention. [bcmj.org]

Up to 30% of individuals with PDDs have epilepsy, 29 although this may be more common in those with lower functioning PDDs. [mja.com.au]

Individuals with autism commonly have one or more additional—called “co-morbid”—problems including epilepsy, anxiety, and gastrointestinal distress, and food allergies. [brainfacts.org]
In contrast, epilepsy associated with intellectual disability predicts poorer outcomes. Adaptive skills are usually below expected for intellectual ability which then impacts education and independence as adults. Young RL, Rodi ML. [emedicine.medscape.com]

Behavior Disorder
At least one co-morbid psychiatric disorder was present in 80.9% of the children; 61.7% had a co-morbid disruptive behavior disorder, and 55.3% fulfilled criteria of an anxiety disorder. [intechopen.com]

Echolalia
Repeat words or phrases over and over (echolalia). Give unrelated answers to questions. Get upset by minor changes. Have obsessive interests. Flap their hands, rock their body, or spin in circles. [brainbalancecenters.com]

Echolalia – the repeating of all or part of what is said to them by someone else – is another common speech pattern among individuals with Autistic Disorder. [opwdd.ny.gov]
As babies, a child with PDD-NOS may not babble or when they do learn words, they exhibit “echolalia” repeating words or phrases over and over again. [childdevelopment.com.au]

Agitation
The patients frequently exhibited anxiety, agitation, aggression, and disruptive behavior. [ps.psychiatryonline.org]
Some psychiatric medications may be helpful in controlling particular behavior difficulties, such as agitation, mood instability, and self-injury. Music, massage, and hydrotherapy may exert a calming effect on behavior. [encyclopedia.com]

Treatment
Child and adolescent mental health professionals help families identify and participate in treatment and educational programs based on an individual child's treatment and educational needs. [stanfordchildrens.org]
While there are many reports of these treatments benefiting a few individuals, there have been no rigorous studies proving the efficacy of any of these treatments. [healthcentral.com]
Community and home-based treatments are generally preferred over institution-based treatments as prolonged institutionalization makes it harder for children with PPD to best develop the social and other skills necessary for optimal functioning in non-institutional [gulfbend.org]
What treatments are there for autism? There is no single best treatment for all children with ASD. The most important point is to start treatment as early and intensively as possible! [med.umich.edu]
Prognosis
Prognosis Early intervention including appropriate and specialized educational programs and support services plays a critical role in improving the outcome of individuals with PDD. [ninds.nih.gov]
Prognosis In general, the prognosis in each of these conditions is tied to the severity of the illness. The prognosis for Asperger’s syndrome is more hopeful than the others in this cluster. [encyclopedia.com]
Parents may receive post-assessment follow-up to discuss the findings, go over any problems, and get answers to questions about diagnosis, prognosis and treatment. [douglas.qc.ca]
The one common denominator for all of the young children is that early intervention does work, and it seems to improve the prognosis.” – Temple Grandin [occupationaltherapychildren.com.au]
Prognosis Pervasive developmental disorders are not life-threatening and do not affect normal life expectancy. Prognosis depends on the severity and type of disorder and the effectiveness of early interventions. [healthofchildren.com]
Etiology
The findings suggest that high- and low-functioning individuals with PDD should be conceptualized as essentially distinct and should be studied separately for etiology, pathophysiology, course, and treatment. [tandfonline.com]
