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]

The diagnosis of PDD-NOS is provided when children demonstrate symptoms of Autism or Asperger and impairment is present, but those symptoms do not cross the threshold for a full syndrome diagnosis. [samgoldstein.com]

• Falling

  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]

• Behavior Disorder

  With respect to the PDD-NOS group, the ADHD group had significantly higher rates of co-morbid disruptive behavior disorders, learning disabilities, tic disorders, elimination disorders, and social anxiety disorder. [intechopen.com]

  Below, we’ll briefly explore some of them: Applied behavioral analysis (ABA). There are several different types of ABA. At its core, ABA is concerned with reinforcing positive behaviors while discouraging negative behaviors. [healthline.com]

  Among the disturbances that have been reported are schizophrenia, mania, depression, suicidal behavior, anxiety disorders, obsessive-compulsive disorder, substance use disorders, catatonia, paranoid ideation, Tourette's disorder, attention-deficit hyperactivity [ps.psychiatryonline.org]

• Confusion

  Not surprisingly, there is a considerable amount of confusion around the term PDD. The problem is that clinicians still sometimes use the term PDD, but they don’t always use it consistently. [appliedbehavioranalysisedu.org]

  Asperger’s Syndrome Asperger’s syndrome is a disorder that can often be confused with autism because of similarities in some behaviours. It has an estimated prevalence of 6 per 10,000 children (Fombonne, 2009). [mcgill.ca]

  Pervasive Developmental Disorder PDD-NOS should not be confused with the term "pervasive developmental disorder." [disabilitysecrets.com]

• Poor Coordination

  Children with Asperger's often also have difficulty concentrating and may have poor coordination. Childhood disintegrative disorder : Children with this rare condition begin their development normally in all areas, physical and mental. [medicinenet.com]

• Convulsions

  A number of neurological conditions, such as convulsions, are commonly found to accompany these disorders. [encyclopedia.com]

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]

As a result, treatments and interventions must be very individualized based on the information gathered from the thorough assessment. “A treatment method or an educational method that will work for one child may not work for another child. [occupationaltherapychildren.com.au]

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]
