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]

Those with IQs in the low-normal range may remain severely socially impaired, and present as if they have intellectual disabilities. [mja.com.au]

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]

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]

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]

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 [mentalhelp.net]

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]

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]

Etiology Researchers continue to identify multiple etiologies for the underlying pathophysiology of pervasive developmental disorder (PDD/ASD). Different levels of dysfunction in CNS systems are most likely involved. [emedicine.medscape.com]

This chapter provides an up-to-date review of the methodological features and substantive results of published epidemiological surveys of the prevalence of pervasive developmental disorders (PDD). [oxfordmedicine.com]

Since the epidemiological data on autism published by Lotter [ 2 ], a number of studies have been reported, but the prevalence rates vary considerably from one study to another. [academic.oup.com]

Prevention of ASD Preventive measures to reduce the incidence or severity of any type of ASD are not known at this time. [stanfordchildrens.org]

Response prevention is physically preventing the learner from responding to the distracters such as physically blocking responses to the distracters until the learner responds independently to the target. [courses.lumenlearning.com]

Can Pervasive Development Disorders Be Prevented? Until more is known about the causes of pervasive development disorders, it is not possible to prevent them. [medicinenet.com]

[…] 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 delay that would prevent [brainbalancecenters.com]

Prevention Pervasive developmental disorders are caused by a complex interaction of genetics, neurological factors, and environmental factors. [healthofchildren.com]
