Background Autism spectrum disorders ASD are a group of biologically based chronic neurodevelopmental disorders characterized by impairments in two major domains: deficits in social communication and social interaction and restricted repetitive patterns of behavior, interests and activities. The exact cause is unknown, but is believed to have many factors, including a strong genetic component. Signs and symptoms of ASD generally appear prior to three years of age and include difficulties with language, deficient social skills and restricted or repetitive body movements and behaviors.
Autism and other autism spectrum disorders ASD may be suspected by the following symptoms: any loss of any language or social skills at any age; no 2-word spontaneous not just echolalic phrases by 24 months; no babbling by 12 months; no gesturing e. Autism has been estimated to affect approximately 1 in 1, children in the United States, and other pervasive developmental disorders have been estimated to affect approximately 2 in 1, children in the United States. Based on recent prevalence estimates of 10 to 20 cases per 10, individuals, between 60, and , children under the age of 15 years meet diagnostic criteria for autism. There is no cure for ASD. However, there is a consensus that treatment must be individualized depending upon the specific strengths, weaknesses and needs of the child and family.
Early diagnosis and early intensive treatment have the potential to affect outcome, particularly with respect to behavior, functional skills and communication. There is increasing evidence that intervention is more effective when initiated as early as possible. Diagnosis and treatment of ASD may involve a variety of tools. Developmental screening, usually performed during a routine well child exam, identifies atypical unusual behaviors such as social, interactive and communicative behaviors that are delayed, abnormal or absent. Once identified, a comprehensive multidisciplinary assessment is recommended in order to make an accurate and appropriate diagnosis.
According to the American Academy of Neurology AAN 's practice parameter, Screening and Diagnosis of Autism Filipek et al, , autism is characterized by severe deficiencies in reciprocal social interaction, verbal and non-verbal communication, and restricted interests. It usually commences before the age of 3 years and lasts over the whole lifetime. Early signs that distinguish autism from other atypical patterns of development include poor use of eye gaze, lack of gestures to direct other people's attention especially to show things of interest , decreased social responsiveness, and lack of age-appropriate play with toys especially imaginative use of toys. A typical symptom of autism is absence of speech development, observed from infancy, taking the form of complete mutism at later stages. It has been emphasized that most pathological symptoms of autism result from altered perception of external stimuli, which arouse fear and anxiety. Currently, there are no biological markers for autism and there is no proven cure for this disorder.
Because there are no biological markers for autism, screening must focus on behavior. These symptoms are stable in children from toddler age through preschool age. Retrospective analysis of home videotapes also has identified behaviors that distinguish infants with autism from other developmental disabilities as early as 8 months of age. There are relatively few appropriately sensitive and specific autism screening tools for infants and toddlers, and this continues to be the current focus of many research centers. The Checklist for Autism in Toddlers CHAT for month-old infants, and the Autism Screening Questionnaire for children 4 years of age and older, have been validated on large populations of children. Performance on tasks that rely on rote, mechanical, or perceptual processes are typically spared; deficient performance exists on tasks requiring higher-order conceptual processes, reasoning, interpretation, integration, or abstraction. Dissociations between simple and complex processing are reported in the areas of language, memory, executive function, motor function, reading, mathematics, and perspective-taking.
However, there is no reported evidence that confirms or excludes a diagnosis of autism based on these cognitive patterns alone. The AAN practice parameter did not recommend that neuropsychological testing be used for the diagnosis of autism, but insteadshould be performed as needed, in addition to a cognitive assessment, to assess social skills and relationships, educational functioning, problematic behaviors, learning style, motivation and reinforcement, sensory functioning, and self-regulation. Psychological testing is recommended in the AACAP practice parameter to assess for cognitive and intellectual functioning, in order to determine eligibility and plan for educational and other services. These features, in conjunction with the increased number of male patients male:female ratio , suggest a genetic predisposition.
On the other hand, parallel evidence of immune abnormalities in autistic patients argues for an implication of the immune system in pathogenesis. Additionally, some neurological disorders such as tuberous sclerosis, neurofibromatosis, fragile X syndrome, Rett syndrome and phenylketonuria may also be associated with autistic features. In these cases, autism is defined as "secondary". The AAN's practice parameter Screening and Diagnosis of Autism Filipek et al, recommended genetic testing in children with autism, specifically high resolution chromosome analysis karyotype and DNA analysis for fragile X syndrome in the presence of mental retardation or if mental retardation can not be excluded , if there is a family history of fragile X or undiagnosed mental retardation, or if dysmorphic features are present.
However, there is little likelihood of positive karyotype or fragile X testing in high-functioning autism. Published studies have reported superior diagnostic yields of newer genetic tests e. However, these findings are not sufficient for drawing a conclusion that use of the tests will lead to improved health outcomes The AAN also recommended lead screening if the child exhibits developmental delay and pica. Autistic regression with epileptiform abnormalities on EEG has been compared by analogy with Landau-Kleffner syndrome and electrical status epilepticus in sleep, but there are important differences between these conditions, and the treatment implications are unclear AAP, Whether subclinical seizures have adverse effects on language, cognition, and behavior is debated, and there is no evidence-based recommendation for the treatment of children with ASDs and epileptiform abnormalities on EEG, with or without regression.
The report states, however, that because of the increased prevalence of seizures in this population, a high index of clinical suspicion should be maintained, and EEG should be considered when there are clinical spells that might represent seizures. Localized structural and functional brain correlates of PDD have yet to be established. Structural neuroimaging studies performed in autistic patients have reported abnormalities such as increased total brain volume and cerebellar abnormalities. However, none of these abnormalities fully account for the full range of autistic symptoms. Functional neuroimaging has demonstrated temporal lobe abnormalities and abnormal interaction between frontal and parietal brain areas. However, the value of functional neuroimaging such as positron emission tomography PET , single photon emission computed tomography SPECT and functional magnetic resonance imaging fMRI in diagnosing autism has not been established.
Functional neuroimaging techniques are at the early stage of identifying abnormalities at the neurotransmitter and systems levels. Further studies with well-defined patient populations and appropriate activation paradigms will better elucidate the pathophysiology of this disorder. Additionally, the AAN stated that there is insufficient evidence to recommend EEG studies in all individuals with autism.
Sleep-deprived EEG study may be performed if the patient has clinical seizures or suspicion of subclinical seizures; or a history of regression clinically significant loss of social and communicative function at any age, but especially in toddlers and pre-schoolers. Moreover, the AAN considered event-related potentials and magnetoencephalography to be research tools, which have no evidence of routine clinical utility Filipek et al, Philip and colleagues stated that recent years have seen a rapid increase in the investigation of ASD through the use of fMRI. A disturbance to the function of social brain regions is among the most well replicated finding. Differences in social brain activation may relate to a lack of preference for social stimuli as opposed to a primary dysfunction of these regions.
Increasing evidence points towards a lack of effective integration of distributed functional brain regions and disruptions in the subtle modulation of brain function in relation to changing task demands in ASD. The authors stated that limitations of the literature to date include the use of small sample sizes and the restriction of investigation to primarily high-functioning males with autism. The AAN Filipek et al, also found inadequate supporting evidence of the following procedures in the management of autism: allergy testing especially food allergy for gluten, casein, candida, and other molds , erythrocyte glutathione peroxidase studies, intestinal permeability studies, stool analysis, and tests for celiac antibodies, immunologic or neurochemical abnormalities, micronutrients such as vitamin levels, mitochondrial disorders including lactate and pyruvate, thyroid function, and urinary peptides.
Hair Analysis is a test in which a sample of an individual's hair, typically from the back of the neck, is sent to a laboratory for measurement of its mineral content. The AAN Filipek et al, found inadequate supporting evidence for hair analysis for treatment of autism. Autistic patients may suffer from gastrointestinal disturbances such as abdominal pains, diarrhea, and the so-called leaky-gut syndrome. Secretin, a hormone produced by the pancreas to stimulate the production of gastric juices, has been used to aid digestion before intestinal biopsy or endoscopy. Secretin is a hormone made in the duodenum which causes the stomach to make pepsin, the liver to make bile and the pancreas to make a digestive juice.
Early case studies suggested that secretin improved gastrointestinal symptoms as well as behavior, eye contact, alertness, and expressive language in autistic children. However, such claims are not borne out by recent well-designed studies. A randomized, double blind, placebo-controlled, cross-over study Corbett et al, investigated the effect of a single intravenous dose of porcine secretin on autistic children. The authors found that significant differences were not observed on the majority of the dependent variables. Statistically significant differences were observed on measures of positive affect and activity level following secretin infusion.
In general, autistic children did not demonstrate the improvements described in the initial retrospective report. This is in agreement with the findings of Owley and colleagues who reported that there was no evidence for efficacy of secretin in a multi-center, randomized, placebo-controlled, double-blind trial. In a single-blinded, prospective, open-label study, Lightdale and associates reported that intravenous secretin had no effects in a 5-week period on the language and behavior of 20 children with autism and gastrointestinal symptoms. The National Academy of Sciences NAS has stated that there is no known cure for autism, and that "[e]ducation, both directly of children, and of parents and teachers, is currently the primary form of treatment for autistic spectrum disorders. Brasic has stated that, while parents may choose to utilize a variety of experimental treatments including medication, they should concurrently utilize intensive individual special education by an educator familiar with instructing children with autistic disorder and related conditions.
The NAS report concluded that "there is little evidence concerning the effectiveness of discipline-specific therapies, and there are no adequate comparisons of different comprehensive treatments. However, there is substantial research supporting the effectiveness of many specific therapeutic techniques and of comprehensive programs in contrast to less intense, nonspecific interventions. This approach includes a functional assessment of the particular behavior to determine its function for a child e. AAC may involve supporting existing speech or developing independent use of a non-speech symbol system, such as sign language, visual symbols pictures and words displayed on communication boards, and voice output devices with synthesized and digitized speech. AT is any commercial, hand-made, or customized device or service used to support or enhance the functional capabilities of individuals with disabilities.
AT includes computer-assisted instruction, mobility devices, high and low technology adaptations and AAC. The objectives of treatment are to improve the child's early social communication and social interaction skills, leading to the potential development of play and flexibility of behavior. The NAS concluded that, although there is substantial research supporting the effectiveness of comprehensive programs in contrast to less intense, non-specific interventions, "there is little evidence concerning the effectiveness of discipline-specific therapies, and there are no adequate comparisons of different comprehensive treatments. It entails the employment of intensive teaching techniques designed to reinforce appropriate social behaviors in children with autism and related disorders. Every task trial consists of a directive to the patient, a response from the patient, and a reaction from the therapist. The patient learns to respond in a manner that generates reinforcement reaction from the therapist.
Lovaas therapy is usually practiced 30 to 40 hours a week. Lovaas therapy was based on a study by Lovaas published in ; however, the study had several problems which include choice of outcome measure, criteria for subject selection and the intellectual level of the subjects, and method for assigning subjects to control groups. These methodological problems made it difficult to ascertain the effects of early behavioral intervention on autistic children. Recent reviews suggested that there is no available treatment that meets criteria for well-established or probably efficacious treatment; and that more research is needed to refine current behavioral treatment approaches.
Delprato compared discrete trial training Lovaas Therapy and normalized behavioral language intervention for young children with autism. The author reported that in studies with language criterion responses, normalized language training was more effective than discrete trial training. Furthermore, in studies that assessed parental affect, normalized treatment yielded more positive affect than discrete trial training. Boyd and Corley reported the outcome survey of early intensive behavioral intervention EIBI programs for young children with autism in a community setting.
Based on both individual case reviews and parent questionnaires, they found that these programs failed to support any instances of "recovery", but yielded a high degree of parental satisfaction. Moreover, a follow-up inquiry into the type of services each child was receiving in his or her post-EIBI setting documented continued dependence on extensive educational and related developmental services, suggesting that the promise of future treatment sparing did not materialize.
The authors concluded that there is a need for further research designed to document the effectiveness of services provided to young children with autism. These programs range from strict operant discrimination learning such as Lovaas therapy to broader applied behavior analysis such as the Rutgers Program to more developmentally oriented programs such as the Denver Program and the Treatment and Education of Autistic and Communication Handicapped Children TEACCH Program. Furthermore, these treatment programs vary in their intensity from 40 hours per week for Lovaas Therapy and the Rutgers Program to a range of 15 hours per week for the LEAP Program. Two of the critical findings of this assessment are as follows: studies on Lovaas therapy were methodologically flawed.
