The pervasive developmental disorders (PDDs) are characterized by patterns of deviance and delay in social-communicative development in the first years of life, which are associated with restricted patterns of interest or behaviour. The prototypic PDD is childhood autism; other conditions included in the PDD class in ICD-10 include Rett's syndrome, childhood disintegrative disorder, Asperger's syndrome, and atypical autism. Except for one additional category in ICD-10 (hyperkinetic stereotyped movement disorder), the disorders included in ICD-10 and DSM-IV are essentially identical. In this chapter each of these conditions will be reviewed in terms of their clinical features, definition, epidemiology, course, and aetiology; final sections of the chapter address aspects of treatment and prevention for the group of disorders as a whole (Box 9.2.3.1).

Aims and methodThe Joint Committee on Higher Psychiatric Training lists the ability to carry out a thorough clinical assessment including physical and mental state examination, as one of the essential core skills in child and adolescent psychiatry. Experience of the assessment of comparatively rare disorders may depend upon the organisation of regional services, as well as good working relationships between teams willing to involve the trainee.ResultsThis paper describes a six-month attachment to the first multi-disciplinary Specialist Assessment Clinic for Pervasive Developmental Disorders to be created in Northern Ireland. Assessments are multi-dimensional and multi-professional. Attachment to this specialist clinic has become a valuable resource, with demand exceeding availability of places.Clinical implicationsThe pervasive developmental disorders are characterised by onset before 36 months, qualitative impairments in social interaction and communication (both verbal and non-verbal), and a pattern of repetitive or stereotyped activities or interests (DSM-IV). Diagnostic criteria for these disorders have broadened since the introduction of DSM-IV and ICD–10. For example, both have now agreed the validity of Asperger's syndrome, featuring difficulties in social interaction, restricted and repetitive areas of interest, without clinically significant impairment of intelligence or language development.

Pervasive developmental disorders are a series of illnesses characterized by delays in the development of some basic functions, such as the ability to communicate and socialize, but also through a small number of interests or activities, and according to ICD-10 (1996), in this category can include childhood autism, where deficiencies at these levels are identified, being identified until the age of three years or atypical autism - common in people with mental retardation or with responsive language disorders. A form of alternative therapy focused on these dimensions is horse-therapy therapy, a rapidly expanding approach in recent years, both with the aim of empirical substantiation and implementation of its different application centers to alleviate psychomotor deficiencies and emotional. This study aims to analyze the results obtained from horse-assisted therapy on psychomotor disorders in children with autistic spectrum disorders, epilepsy, ADHD or cerebral palsy. A group of 64 children aged between 2 and 14 years, biological age, participated in the study. 41 children were part of the study group, 23 constituting the control group. A controlled research model with pretest-posttest measurements was used. The effect of horse therapy on adaptive skills was evaluated. The ABAS II Adaptive Behavior Assessment System was used to measure these skills. The results indicate that hypothyroid therapy is effective in increasing the adaptability of children with psychomotor disorders.

Background: Pervasive Developmental Disorders (PDD) are group of developmental disorder with impairments in interaction, communication and behaviour. The study aims to explore the phenomenological aspects of subjects with PDD.Methods: Patients in Psychiatry outpatient department (OPD), presented with impairment in social- interaction, language, communication and mental retardation were assessed for features of PDD by applying Developmental Behaviour Check List (DBCL), ICD-10 Diagnostic Criteria for Research and Multi-Axial version of ICD-10. The subjects were assessed for severity of PDD on Childhood Autism Rating Scale (CARS).Results: Total number of screened positive cases were 20, in which males were over-represented (90%). Majority belonged to urban locality (65%) and nuclear family (75%). Cases of childhood autism were found in all age groups, while childhood disintegrative disorder, Rett’s disorder and atypical autism were found in younger subjects. No family history of PDD was found in 1st degree relatives of PDD subjects. Five subjects (25%) had birth and perinatal complication.Conclusions: The mean age at presentation of the children with PDD was 8.12 years. Eighty percent (80%) of the subjects had severe autism on CARS.  Hyperactivity, inattention and impulsivity were present in 90%, 80% and 45% of subjects respectively.

With the aim of analyzing which complementary tests are relevant in the diagnostic evaluation of individuals with pervasive developmental disorders, a protocol of clinical and laboratory evaluation was applied in 103 outpatients. The protocol included chromosomal analysis, screening for inborn errors of metabolism, cytogenetic and molecular study of the FRAXA, FRAXE, and FRAXF mutations, EEG, SPECT, and magnetic resonance imaging study. Eighty-four subjects concluded the complementary tests and were classified either as having autism, atypical autism or Asperger syndrome according to the DSM-IV criteria. Sixteen individuals, all bellonging to the two autistic groups, presented genetic or enviromental factors that may have lead to the behavioral disorders, showing the importance of diagnostic evaluation in this group of conditions. Neuroimaging and EEG findings were non-specific and occurred in similar proportion among the groups, being considered of relative low significance in the diagnostic evaluation of individuals with pervasive developmental disorders.

BackgroundDSM-IV and ICD-10 are atheoretical and largely descriptive. Although this achieves good reliability, the validity of diagnoses can be increased by an understanding of risk factors and other clinical features. In an effort to group mental disorders on this basis, five clusters have been proposed. We now consider the second cluster, namely neurodevelopmental disorders.MethodWe reviewed the literature in relation to 11 validating criteria proposed by a DSM-V Task Force Study Group.ResultsThis cluster reflects disorders of neurodevelopment rather than a ‘childhood’ disorders cluster. It comprises disorders subcategorized in DSM-IV and ICD-10 as Mental Retardation; Learning, Motor, and Communication Disorders; and Pervasive Developmental Disorders. Although these disorders seem to be heterogeneous, they share similarities on some risk and clinical factors. There is evidence of a neurodevelopmental genetic phenotype, the disorders have an early emerging and continuing course, and all have salient cognitive symptoms. Within-cluster co-morbidity also supports grouping these disorders together. Other childhood disorders currently listed in DSM-IV share similarities with the Externalizing and Emotional clusters. These include Conduct Disorder, Attention Deficit Hyperactivity Disorder and Separation Anxiety Disorder. The Tic, Eating/Feeding and Elimination disorders, and Selective Mutisms were allocated to the ‘Not Yet Assigned’ group.ConclusionNeurodevelopmental disorders meet some of the salient criteria proposed by the American Psychiatric Association (APA) to suggest a classification cluster.

For a long time, there was a strong belief of existing continuity between childhood-onset psychoses and adult psychoses. Important moment in understanding psychotic presentations during infancy and childhood is Kanner's description of early infantile autism. Later studies of Rutter and Kolvin, as well as new classification systems, have delineated pervasive developmental disorders from all other psychotic disorders in childhood. But clinical experience is showing that in spite of existence of the group of pervasive developmental disorders with subgroups within it and necessary diagnostic criteria there are children with pervasive symptoms, who are not fulfilling all necessary diagnostic criteria for pervasive developmental disorder. Therefore, in this paper we are discussing and pointing at psychotic spectrum presentations in children, which have not the right place in any existing classification system (ICD-10, DSM-IV).

Pervasive developmental disorders (PDD)is defined as a neurodevelopmental disorder,c haract erized by social withdrawal,communication deficits, and repetitivebehaviors. PDD include autistic disorder, Rett'ssyndrome, childhood disintegrative disorder, Asperger' ssyndrome, and pervasive developmental disorder nototherwise specified or atypical autism.1 Update ofepidemiological studies published between 1966 and2006 show reports of estimated prevalence for autismhas varied between 3 .31 and 86 children per 10,000, 2and predominantly occurs in males than females(male:female ratio = 4: 1) .3There is a hypothesis that behavioral problemsin children with pervasive developmental disorderare highly associated with the neurotransmitterimbalances. Therefore, psychotropic medications (eg.atypical antipsychotics, selective serotonin reuptakeinhibitors, and psychostimulants), which work ondopamine and serotonin receptors, are the FDAapprovedmedications for PDD.4 On the other hands,the use of novel, unconventional, and/or off- labeltreatments associated with the n eurotransmitterspathway for children with POD is increasing andmore common.

Background. Based on prevalence studies and the few incidence studies of pervasive developmental disorders (PDDs) the prevalence and incidence of these disorders have been claimed to be increasing.Method. The annual and age-specific prevalence and incidence rates of childhood autism, atypical autism, Asperger's disorder, and pervasive developmental disorder not otherwise specified (PDD-NOS) in Denmark during the period 1971–2000 in children younger than 10 years were estimated using data from the Danish Psychiatric Central Register.Results. A total of 2·4 million children younger than 10 years were followed and 2061 cases with the PDDs studied were identified. Generally, the prevalence and incidence rates of the PDDs studied were stable until the early 1990s after which an increase in the occurrence of all disorders was seen, until 2000. The annual incidence rate per 10000 children younger than 10 years was 2·0 for childhood autism, 0·7 for atypical autism, 1·4 for Asperger's disorder, and 3·0 for PDD-NOS in 2000. We calculated a ‘corrected’ prevalence of childhood autism at 11·8, atypical autism at 3·3, Asperger's disorder at 4·7, and PDD-NOS at 14·6 per 10000 children younger than 10 years on 1 January 1 2001.Conclusions. We found that the estimated prevalences of the PDDs studied were probably underestimated. Furthermore, the increasing prevalence and incidence rates during the 1990s may well be explained by changes in the registration procedures and more awareness of the disorders, although a true increase in the incidence cannot be ruled out.
