A routine prenatal ultrasound can identify early signs of autism, study finds. Summary: A routine prenatal ultrasound in the second trimester can identify early signs of Autism Spectrum Disorder (ASD), a new study has found.
In the United States, prenatal genetic testing (PGT) for Autism Spectrum Disorders (ASD) is currently available via clinical genetic services. Such testing may inform parents about their unborn child's risk for ASD, prepare parents for the birth of an affected infant, and allow them to arrange for early interventions.
They also noted that autism was most associated with anomalies in the urinary system, heart, head, and brain. They further found that those with autism tended to have a narrower head and a relatively wider ocular distance compared to typically developing fetuses.
Epidemiological studies have shown that hormone abnormalities in pregnant women are a significant potential risk factor for autism in offspring and that sex hormones may be part of the cause of autism.
Risk Factors
Having a sibling with ASD. Having certain genetic or chromosomal conditions, such as fragile X syndrome or tuberous sclerosis. Experiencing complications at birth. Being born to older parents.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Research findings mention taking supplements such as folate (folic acid), omega-3s, and vitamin D3, correcting vitamin deficiencies, boosting your immune system, and prolonging breastfeeding as possible ways to reduce the risk of autism (though, of course, they can't eliminate the risk altogether).
While autism is typically not diagnosed before the age of 2 (and often much later), it can sometimes be detected earlier. A 2022 study found that a routine second-trimester ultrasound could detect early signs of autism during pregnancy,19 including anomalies in the heart, head, and kidneys.
A routine prenatal ultrasound in the second trimester can identify early signs of Autism Spectrum Disorder (ASD), a new study by Ben-Gurion University of the Negev and Soroka Medical Center has found.
One study found that the chance of having ASD for children born to parents who are in their thirties is up to 10 percent higher than parents who are 25 to 29 years old. The same researchers found that the chance of developing ASD is 50 percent higher when the parents are in their 40s or 50s.
Inheritance. ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.
High levels of stress during pregnancy may also be connected to autism in children. This connection appears to have the most impact when the parent experiences stress between weeks 25 and 28 of pregnancy.
So, are Down syndrome and autism the same thing or the same disorder? No. They are distinct disorders with different causes that may show some similar symptoms, but also differences.
Health care providers can check for Down syndrome during pregnancy or after a child is born. There are two types of tests for Down syndrome during pregnancy: A prenatal screening test. This test can show an increased likelihood that a fetus has Down syndrome, but it cannot determine Down syndrome is definitely present.
Advanced parental age at time of conception. Prenatal exposure to air pollution or certain pesticides. Maternal obesity, diabetes, or immune system disorders. Extreme prematurity or very low birth weight.
Unbalanced dietary patterns before conception may be related to long-term maternal metabolic conditions such as metabolic syndrome, obesity and diabetes. Those conditions have also been identified as environmental risk factors for ASD as well as other neurodevelopmental disorders.

Autism genetics expert Ivan Iossifov breaks down recent research that sheds light on how unaffected parents can pass autism onto their child. Parents with no history of autism in their families have a child who is diagnosed with the disorder. It's a common and upsetting story.
The Autism Phenome Project and Girls with Autism, Imaging of Neurodevelopment studies rely on MRI scans of the same children – both with and without autism - over many years in order to track brain development. Scanning the brain of a young child is less challenging; it's done while they're asleep.
Neuropsychological assessment provides a profound analysis of cognitive functioning in people with autism spectrum disorder (ASD). Individuals on the autistic spectrum often show a high level of anxiety and are frequently affected by comorbidities that influence their quality of life.
