BACKGROUND Autism spectrum disorder is a diagnosis that is increasingly applied; however, previous studies have conflicting findings whether rates of diagnosis rates continue to grow in the UK. This study tested whether the proportion of people receiving a new autism diagnosis has been increasing over a twenty-year period, both overall and by subgroups. METHOD Population-based study utilizing the Clinical Practice Research Datalink (CPRD) primary care database, which contains patients… 

Evidence of increasing recorded diagnosis of autism spectrum disorders in Wales, UK: An e-cohort study

An anonymised e-cohort comprised of healthcare record data is used to produce all-age estimates of prevalence and incidence of recorded autism for the years 2001–2016, finding the overall prevalence rate of autism in healthcare records was 0.51%.

Childhood diagnoses in individuals identified as autistics in adulthood

Most childhood diagnoses were overrepresented in those with an adult autism diagnosis, and attention-deficit hyperactivity disorder, affective disorders, anxiety, and stress disorders were the most prevalent childhood conditions in this group.

Race and Sex Bias in the Autism Diagnostic Observation Schedule (ADOS-2) and Disparities in Autism Diagnoses

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition that affects an estimated 1 in 44 children in the US, with a male-to-female ratio of approximately 4:1. 1 The prevalence

Autism Diagnostic Assessments With Children, Adolescents, and Adults Prior to and During the COVID-19 Pandemic: A Cross-Sectional Survey of Professionals

The pandemic has potentially compounded existing bottlenecks to the autism diagnostic pathway and there is a general openness to using this method (potentially in a hybrid telehealth—in person model), provided rigor and standardization are enhanced.

Precision Autism: Genomic Stratification of Disorders Making Up the Broad Spectrum May Demystify Its “Epidemic Rates”

Viewing Autism through this physiological (Precision) lens, rather than viewing it exclusively from a psychological behavioral construct, may make it a more manageable condition and dispel the Autism epidemic myth.

Symptoms of Autism Spectrum Disorders Measured by the Qualitative Checklist for Autism in Toddlers in a Large Sample of Polish Toddlers

Assessment of some early symptoms of autism spectrum disorders measured by a screening tool developed for an early detection of ASD found that mean Q-CHAT scores were significantly higher in boys than in girls and in toddlers with a developmental delay.

Future Prospects for Epigenetics in Autism Spectrum Disorder.

A review examines recent studies of the ASD epigenome, detailing common gene pathways found to be differentially methylated in people with ASD, and considers how these discoveries may inform the understanding of ASD etiology.

Factor associated with the occurrence of epilepsy in autism: a systematic review.

Intellectual disability/cognitive impairment was the most commonly reported risk factor associated with occurrence of epilepsy in autistic individuals and the evidence supporting other, potentially relevant factors was weak and inconsistent and requires further evaluation.

Debate: Child and adolescent mental health professionals have a responsibility to diagnose Personality Disorder.

In the United Kingdom, mental health professionals have been historically reluctant to diagnose Personality Disorder in young people over many decades, and there is little evidence that much has

Measuring subjective quality of life in autistic adults with the PROMIS global-10: Psychometric study and development of an autism-specific scoring method.

The findings suggest that the new Patient-Reported Outcomes Measurement Information System Global-10 quality of life score is a reliable and valid measure ofquality of life in autistic adults, although additional studies are necessary to further explore its measurement properties in other subsets of the autistic population, such as individuals with intellectual disabilities.

Autism phenotype versus registered diagnosis in Swedish children: prevalence trends over 10 years in general population samples

The prevalence of the autism symptom phenotype has remained stable in children in Sweden while the official prevalence for registered, clinically diagnosed, autism spectrum disorder has increased substantially, suggesting that administrative changes, affecting the registered prevalence, rather than secular factors affecting the pathogenesis, are important for the increase in reported prevalence.

Autism prevalence trends over time in Denmark: changes in prevalence and age at diagnosis.

Shifts in age at diagnosis inflated the observed prevalence of autism in young children in the more recent cohorts compared with the oldest cohort, supporting the argument that the apparent increase in autism in recent years is at least in part attributable to decreases in the age at diagnosed over time.

Rate of first recorded diagnosis of autism and other pervasive developmental disorders in United Kingdom general practice, 1988 to 2001

Better ascertainment of diagnosis is likely to have contributed to the observed temporal increase in rates of diagnosis of PDD, but there was marked geographical variation in rates with standardised incidence ratios varying from 66 for Wales to 141 for the South East of England.

Prevalence and incidence rates of autism in the UK: time trend from 2004–2010 in children aged 8 years

Following a fivefold increase in the annual incidence rates of autism during the 1990s in the UK, the incidence and prevalence rates in 8-year-old children reached a plateau in the early 2000s and remained steady through 2010.

The Rise in Autism and the Role of Age at Diagnosis

Autism incidence in California shows no sign yet of plateauing, and younger ages at diagnosis, differential migration, changes in diagnostic criteria, and inclusion of milder cases do not fully explain the observed increases.

Validation of autism spectrum disorder diagnoses recorded in the Clinical Practice Research Datalink, 1990–2014

The results of this study suggest that ASD diagnoses recorded in the CPRD are reliable and can be used with confidence to study ASD.

Cohort effects explain the increase in autism diagnosis among children born from 1992 to 2003 in California.

Autism incidence in California exhibits a robust and linear positive cohort effect that is stronger among high-functioning children with an autism diagnosis, indicating that the primary drivers of the increases in autism diagnoses must be factors that have increased linearly year-to-year.

Secular changes in the symptom level of clinically diagnosed autism

The findings add support for the notion that the observed increase in autism diagnoses is, at least partly, the by-product of changes in clinical practice, and flag up the need for working in agreement with best practice guidelines.

Trends in the Prevalence of Developmental Disabilities in US Children, 1997–2008

Autism, attention deficit hyperactivity disorder, and other developmental delays increased, whereas hearing loss showed a significant decline, and trends were found in all of the sociodemographic subgroups, except for autism in non-Hispanic black children.

Early detection of—and intervention to treat—ASD is crucial because it is likely to lead to an improved outcome, and early diagnosis will lead to earlier behavior-based intervention, which is associated with improvements in core areas, such as social functioning and communication.
