In normal development, the head will maintain a vertical position. A child with an autistic spectrum disorder will often fail to keep his head vertical, instead holding the head in line with the rest of the body.

The following information applies generally to adults who discover that previous misdiagnoses or no diagnosis with a "lifelong feeling of being different" has led them to the point of their seeking the proper label. For all adults, the diagnostic process, conducted by a competent, knowledgeable and sensitive professional or professional team, is a life-changing experience. Whether one discovers autism, non-verbal learning disability, attention deficit disorder (inattentive or combined type), or any combination of other developmental or mental health conditions that finally seem to fit, the following description of the process seems to make sense for most individuals.

The research included 91 children seen by developmental pediatrician James Coplan, M.D., between 1997 and 2002. The children had autistic spectrum disorders (ASD), which include classic autism, pervasive developmental disorder and Asperger's syndrome. Dr. Coplan looked at the relationship between the severity of the disorder, IQ measurement, and time. One of the main findings of the study is ASD children in the normal range of intelligence show significant improvement in their autistic symptoms over time. This means doctors can let parents know their child will improve, giving them hope for the future.

The rise in autism cases is not evidence of an epidemic but reflects better diagnosis of autism by schools, according to a study released last week. The number of children classified by US special education programs as mentally retarded or learning disabled has declined in tandem with the rise in autism cases between 1994 and 2003, the study's author said, suggesting a switch of diagnoses.

Autism in children can be detected as early as age 14 months, a new study shows. Autism is rarely diagnosed before a child is 3 years old. Cutting that time in half means less precious time lost in getting autistic children the treatment they urgently need -- when it's likely to do the most good. The new finding comes from researchers including Rebecca Landa, PhD, director of the center for autism and related disorders at Kennedy Krieger Institute in Baltimore. Landa tested motor, language, and visual skills in the younger siblings of autistic children. Such children are 100 times more likely to be autistic than other children.

Most adults who are diagnosed with AS, no matter what process they have to work through in understanding and self-acceptance, find the diagnosis a meaningful revelation in their lives. Substantial enough in scope, is this diagnosis, that it can mean the difference between a life of self-recrimination, self-loathing, self-hatred, isolation, alienation, or an increased understanding of self that enables those diagnosed with AS to make much more sense out of their lives and experiences.

The signs of autism may be evident in early infancy in at least some children, although such symptoms are probably too subtle to definitively diagnose the disease until later in life.
Using a structured approach to screening for behavioral problems is being recommended in this Webcast because a number of research studies have shown that usual care misses a substantial portion of behavioral problems.

Unless specifically trained in the area of DD's, physicians and psychologists may have little experience with ASD's. it's important to look for someone who shows respect for the parents and regards parents as experts on their children.

No single gene, environmental factor, combination of genes and/or environment, or other risk factors, can consistently cause autism. I doubt that we will find such a gene or agent but we will most certainly continue to identify new causes, potential treatments, comorbidities, categories, and labels cleaved from the idiopathic autism realm. There's a lot to sort out before we can say that one thing is caused by another so our only option for now is to ignore symptoms that may or may not be associated with being autistic, or continue to discuss these things as potential comorbid conditions. Humans will always sort, catalog, and label all we encounter. We need to exercise great caution when we approach categorizing humans by comorbidities.
This study compares DSM-IV symptoms in children (ages 6 to 12 years) with pervasive developmental disorder (PDD), clinic controls, and community-based samples. Parents/teachers completed the Child Symptom Inventory–4 for four samples: PDD (N= 284/284) and non-PDD psychiatric clinic referrals (N= 189/181) and pupils in regular (N= 385/404) and special (N= 61/60) education classes. The PDD group received higher symptom severity ratings than the regular education group, but was similar to the non-PDD clinic sample. Screening prevalence rates were highest for ADHD, ODD, and generalized anxiety disorder. PDD subtypes exhibited differentially higher rates of psychiatric symptoms. The magnitude of rater and gender differences in symptom severity ratings was modest. Clinic-referred children with PDD exhibit a pattern of psychiatric symptoms highly similar to nonPDD clinic referrals. Although much additional research is needed on comorbidity, these symptoms have important treatment implications.

The work of Michael Rutter, MD, FRS, F Med Sci, Professor of Psychiatry, Institute of Psychiatry in London and of Dante Cicchetti, MD, McKnight Presidential Chair and Professor, Institute of Childhood Development and Department of Psychiatry, University of Minnesota, Minneapolis pioneered the fusion of epidemiology and developmental psychopathology, an area of study into which more recent investigators have folded new techniques using genetics and biomarkers. Included in the long list of conclusions presented: "Comorbidity can be expected in almost every child seen in a mental health setting." "Onset before adulthood may be a characteristic of the majority of adult psychiatric disorders."

A brief observation in a single setting cannot present a true picture of an individual's abilities and behaviors. Parental (and other caregivers') input and developmental history are very important components of making an accurate diagnosis.
In this paper, we give an overview of the diagnostic categories of autism and other pervasive developmental disorders (PDDs) and discuss the changes in the DSM classification system over the past 20 years. We describe each subtype of PDD, along with comorbid psychiatric conditions, assessment guidelines, and tools for diagnosis. The epidemiology of autism has generated much discussion and research; we report the most recent data, as well as recent findings about controversial issues purporting to cause the increased prevalence rate observed in the past decade. Finally, we discuss the prognosis for individuals with autism, indicating the challenges faced by patients, families, and professionals aiming to optimize their outcome.

Overall, I would like to encourage physicians to not eliminate autism as a possibility when talking to parents of particular children -- especially when you haven't seen that child in a positive social relationship. In other words, be very careful not to tell parents that this isn't autism. Those are words that parents will hang on to for many years. Again, it's harder to rule out autism in very young children than it is to identify it. So, when in doubt, it is really important for the physician to get help and refer the child on to a specialist.

Diagnostic criteria for autism and background characteristics used by 937 Indian psychiatrists, psychologists and pediatricians were examined. Participants were asked to rate 18 behaviors as necessary for a diagnosis of autism, helpful but not necessary, or not helpful in a diagnosis of autism, and were asked to provide other information about their experiences with autism. Professionals' experience with diagnosing cases did not vary by profession and, in general, the three professions agreed about the characteristics most necessary for a diagnosis. However, within-group differences were found on the agreement over the usefulness of individual characteristics and amount of experience diagnosing cases as autistic. Comparisons with DSM-III and DSM-IV criteria suggest that Indian professionals may adhere to these systems. Conclusions about diagnosis in a cultural context and areas for future research are suggested.

he more widespread availability of early intervention and growing evidence of its efficacy for children with autism spectrum disorders (ASDs) have led to a recent emphasis on screening and early diagnosis. ASDs, which include autism, Asperger's disorder, and pervasive developmental disorder-not otherwise specified (PDD-NOS), currently have no biological marker. They are defined by behavior, including the absence of normal social engagement and communication, and the presence of unusual repetitive behaviors. Screening and diagnosis require accurate behavioral reports or observations. In this article, we will discuss screening and diagnosis, with reference to current research on identification of children with ASD at age 2 years or younger, through population (level 1) and focused (level 2) screening, and then with standard diagnostic methods.

Forty-one children with pervasive developmental disorders (PDDs) receiving eclectic services were assessed twice during their preschool years. Measures were compared over time for the whole group and for diagnostic subgroups: Childhood autism (CA group) and Other PDDs group. The mean intelligence quotient/developmental quotient (IQ/DQ) of the whole group was stable (P = 0.209) and scores on the Childhood Autism Rating Scale (CARS) decreased (P = 0.001). At time 2, the CA group was more impaired than the other PDDs group: autistic symptoms were more severe (P = 0.01), adaptive behavior scores were lower (P = 0.014), and a trend for lower IQ/DQs (P = 0.06). Children in this study seemed to fare better than reported in previous follow-up studies on children with autism.

I try to be really careful about not completely disregarding complementary or alternative sorts of treatments, but I do draw a line around such treatments that I feel may be harmful to the patient. So in patients who are involved in IV chelation, strange behavioral interventions, or taking different sorts of medications that don't have good clinical research backing them up and may have harmful side effects, I do challenge the parents to be careful. And there are a lot of unscrupulous doctors who don't have training in developmental disabilities and who are willing to takes parents' money to perform all sorts of treatments that don't necessarily create any good and may cause significant harm for the kids.
Whilst the numbers of patients with autism on their lists are increasing, provision of effective assessment and referral is not guaranteed. GPs require more guidance and training in identifying signs that a patient may have autism.

ASDs can normally be diagnosed at around the age of two years. In many instances professional workers may spot the tell-tale signs of autism via the normal childhood health checks and this will eventually result in them being formally diagnosed.
National Autistic Society
While the more overt symptoms of autism are typically more obvious in early childhood, the symptoms of AS may only become apparent with the increasing functional and social demands of adolescence. In the adolescent with AS, the stress of unrecognized disability, limited achievement, and a sense of failure are often revealed by increasing contrast with siblings and peers. Family and peers may become exasperated by the person's self-centered insensitivity, obsessiveness, and rigid inflexibility, further distorting personal relationships. All these factors can add secondary disability and result in dependency that is disproportionate to the person's intellectual ability.
Mary Muscari, Medscape
Twenty children who presented with severe interactional and communication difficulties at age 2 underwent a comprehensive assessment for autism, and were reassessed at age 4-5. In common with other recent studies, diagnosis of autistic spectrum disorders at age 2 was found to be reliable and stable. The communication and social skills of the children showed little change overall by the second assessment. However, children whose scores deteriorated in the social domain tended to have presented initially with more significant behaviour problems. Few repetitive behaviours were observed at age 2, whereas these were more apparent by age 4-5. The finding that early diagnosis of autism is reliable and stable has led to the development of an early diagnostic service in Southampton, which is described. The importance of early diagnosis is that it opens the door to early intervention programmes, which in turn prevent many problems from occurring in later life.

To facilitate examination of school psychologist ASD identification roles and responsibilities, this paper begins with an overview of ASD and provides a general discussion of diagnostic and special education eligibility classifications. Next, it specifically identifies potential school psychologist ASD identification roles, responsibilities, and limitations. Finally, the paper provides a detailed discussion of the identified roles and responsibilities. From prior papers by Filipek et al.+ these roles and responsibilities are identified as follows: a) case finding, b) screening and referral, c) diagnostic assessment, and e) psycho-educational assessment.

Early identification of developmental disorders is critical to the well-being of children and their families. It is an integral function of the primary care medical home and an appropriate responsibility of all pediatric health care professionals. This statement provides an algorithm as a strategy to support health care professionals in developing a pattern and practice for addressing developmental concerns in children from birth through 3 years of age. The authors recommend that developmental surveillance be incorporated at every well-child preventive care visit. Any concerns raised during surveillance should be promptly addressed with standardized developmental screening tests. In addition, screening tests should be administered regularly at the 9-, 18-, and 30-month visits. (Because the 30-month visit is not yet a part of the preventive care system and is often not reimbursable by third-party payers at this time, developmental screening can be performed at 24 months of age. In addition, because the frequency of regular pediatric visits decreases after 24 months of age, a pediatrician who expects that his or her patients will have difficulty attending a 30-month visit should conduct screening during the 24-month visit.) The early identification of developmental problems should lead to further developmental and medical evaluation, diagnosis, and treatment, including early developmental intervention. Children diagnosed with developmental disorders should be identified as children with special health care needs, and chronic-condition management should be initiated. Identification of a developmental disorder and its underlying etiology may also drive a range of treatment planning, from medical treatment of the child to family planning for his or her parents.

Assessment and testing procedures are often seen negatively by parents and poorly perceived by the autistic person being tested. It is quite right to observe that that assessments are being too often administered in a cold "Pass-Fail" procedure that is very often cause of negative feelings from the part of the person being assessed. I believe the roots of the problem are two fold: 1) Poor test/assessment procedure design; 2) Poor skills of the test administrator

Too few pediatricians screen children for autism and autism spectrum disorders (ASD), and a lack of familiarity with screening tools seems to be a major factor, a U.S. study finds. The study of 255 Maryland and Delaware pediatricians found that 209 (82 percent) said they regularly screen their patients for general developmental delays, but only 20 (8 percent) of them said they regularly screen for ASD.
Whilst most individuals with pervasive developmental disorders can be managed effectively by local services, for the most complex or subtle cases there is an ongoing need for specialist assessment and treatment services.

The way that a doctor presents a diagnosis can strongly influence parents' response to it. Although autistic individuals face significant challenges throughout their lives, it is irresponsible for a doctor to automatically predict that an autistic toddler "will probably never speak." Such a scenario derives from outdated definitions of autism that relegated the label to severely impaired children. In fact, 90% of children on the autistic spectrum develop speech by the age of nine. As diagnostic criteria have broadened and understanding of autism has evolved, so too must clinicians support parents in formulating a realistically positive vision of their children's future.

The high specificity and positive predictive value of the CHAT means that it could be used as a screening instrument within a broader surveillance programme to identify cases before they had come to attention by other means.

The "whirling" response or test has been described as highly specific for childhood schizophrenia. The test is performed as follows: The child stands with his arms extended, parallel to each other, and with his eyes closed. In order that he may be distracted, he is asked to count. The head is now passively rotated to one side as far as possible without discomfort. Reaction is noted and the head is rotated to the other side. The positive resonse, or whirling, consists of the child's turning his entire body as long as the examiner turns his head. The negative response consists of a slight rotation of the trunk but the entire body does not turn. Although the validity and relability of the whirling test have never been demonstrated, the test is presented in the literature not only as a diagnostic aid but as a characteristic sign of schizophrenia. Furthermore, the test has been offered as important evidence for the "maturational lag" concept of childhood schizophrenia.
