Autism spectrum disorders (ASDs) affect an estimated 1% of children in the United States. The etiology is probably multifactorial, including genetic components and exposure to infections, toxins, and other environmental factors, particularly unfavorable perinatal and neonatal conditions. There has been an increase in the frequency of diagnosis of ASDs over the last 20 years with a parallel increase in the use of obstetric diagnostic ultrasound, with prenatal ultrasound exposure mentioned as the… 
Association of Prenatal Ultrasonography and Autism Spectrum Disorder
This study found significantly greater mean depth of ultrasonographic penetration in the ASD group compared with the developmental delay group in the first trimester andCompared with the typical development group, the ASD group had shorter duration of ultrasound exposure during the first and second trimesters but no difference in the number of scans.
Is Excessive Prenatal Ultrasonography a Risk Factor for Autism? A Literature Review
Excessive PUS usage and ASD development is focused on and enhanced biophysical adverse effects may link the analogous increase in prenatal ultrasonography and autism, and prenatal ultrasound may emerge as a risk factor for autism.
Continuous electronic fetal monitoring during prolonged labor may be a risk factor for having a child diagnosed with autism spectrum disorder.
Two developments in today's childbirth experience that, in combination, may provide the key: a significant increase in the mean duration of labor and the adoption of continuous electronic fetal monitoring utilizing Doppler ultrasound as the standard of care even in low-risk pregnancies are identified.
Epidemiologic Features of Autism Spectrum Disorders
The number of potential environmental, genetic, developmental, and biological risk factors for autism points to a multifactorial etiology.
Integrative Pediatrics and Child Care Autism and its Obstetrical Causes
There are numerous speculations about the cause of ASD. Some theories include vaccinations, toxic nutrients, maternal obesity, prenatal fever, use of oxytocin, among others [1]. The report from the

Mice Exposed to Diagnostic Ultrasound In Utero Are Less Social and More Active in Social Situations Relative to Controls
Fetal exposure to diagnostic ultrasound applied in utero can alter typical social behaviors in young mice that may be relevant for autism, and meaningful differences between the exposure of diagnostic ultrasound to mice versus humans require further exploration.

Ultrasound was used for the first time in pregnancy in the 1960 s and then found broader clinical application in the 70 s and particularly in the 80 s, thereby revolutionizing obstetrics and
Ultrasound in the First Trimester and Earlier: How to Keep It Safe
To guarantee safety, education of the end-users is vital on precautions to limit the possible hazards of exposure of the follicles/ova and the fetus at early stages of gestation, and DUS should be used only when medically indicated.
Benefits and risks of ultrasound in pregnancy.
Diagnostic ultrasound is a form of energy and, as such, demonstrates effects in biological tissues it traverses (bioeffects), and the physical mechanisms responsible for these effects are thermal or non-thermal (mechanical).


Perinatal factors and the development of autism: a population study.
The increased prevalence of obstetric complications among autism cases is most likely due to the underlying genetic factors or an interaction of these factors with the environment.
Antenatal Ultrasound and Risk of Autism Spectrum Disorders
It is indicated that antenatal U/S is unlikely to increase the risk of ASD, although studies examining ASD subgroups remain to be conducted.
The epidemiology of autism spectrum disorders.
Future epidemiologic research should focus on expanding population-based descriptive data on ASDs, exploring candidate risk factors in large well-designed studies incorporating both genetic and environmental exposure data and addressing possible etiologic heterogeneity in studies that can stratify case groups and consider alternate endophenotypes.
Autism spectrum disorders in extremely preterm children.
These symptoms and disorders were associated with neurocognitive outcomes, suggesting that ASD may result from abnormal brain development in this population of extremely preterm children in middle childhood.
Maternal Metabolic Conditions and Risk for Autism and Other Neurodevelopmental Disorders
Maternal MCs may be broadly associated with neurodevelopmental problems in children, and with obesity rising steadily, these results appear to raise serious public health concerns.
Fetal exposure to teratogens: Evidence of genes involved in autism
Current understanding of the relationship between in utero exposure to these drugs and autism in humans and in autism-like animal model phenotypes is summarized.
Prenatal, Perinatal, and Neonatal Factors Associated With Autism Spectrum Disorders
The association between breech presentation and autism spectrum disorders in this study suggests a shared etiology rather than causal relationship and additional investigation focused on both genetic and environmental factors that link these autism spectrum disorder risk factors individually or collectively is needed.
Autism spectrum disorders and epigenetics.
Data reviewed in this article highlight a variety of situations in which epigenetic dysregulation is associated with the development of ASD, thereby supporting a role for epigenetics in the multifactorial etiologies of ASD.
Prenatal, Perinatal, and Neonatal Factors in Autism, Pervasive Developmental Disorder-Not Otherwise Specified, and the General Population
The results of this study support previous findings suggesting a consistent association of unfavorable events in pregnancy, delivery, and the neonatal phase and the pervasive developmental disorders.

Progress on the elucidation of the causes of autism will be crucially dependent on the combination of epidemiology with more basic science laboratory studies.
