Do Autistic Toddlers Laugh
Children with autism mainly produce one sort of laughter voiced laughter, which has a tonal, song-like quality. This type of laughter is associated with positive emotions in typical controls. In the new study, researchers recorded the laughter of 15 children with autism and 15 typical children aged 8 to 10 years.
Tests For Chromosomal Problems
You might be offered a screening test to check if your baby has a chromosomal problems such as Down syndrome, Edwards syndrome and Pataus syndrome.
You’ll be offered this if your baby is at increased risk. For example, because of your age or because you previously had a baby with one of these syndromes.
If the results show that there’s a high risk of your baby having one of these conditions, it can lead to you having to make very difficult decisions about whether you want to continue with the pregnancy.
You also may have to make a decision whether to have a diagnostic test which could have a risk of miscarriage.
What Is The Nt Measurement
- The nuchal translucency is a fluid filled space at the back of every babys neck
- A larger NT measurement is associated with an increased chance for chromosome disorders like Down syndrome and some other genetic and non-genetic issues like congenital heart defect
- An ultrasound to measure NT is performed between 11 and 14 weeks of pregnancy and should be done at a certifiedultrasound site. Your health care provider will tell you where an NT ultrasound can be obtained.
- An NT measurement of 3.5 mm or bigger is considered significant and would be a screen positive. A referral for genetic counselling will likely be offered.
Table 1 has an overview of the prenatal screening tests available in Ontario and how they compare to each other. Not all test options are available in all areas.
Enhanced First Trimester Screening is the most commonly offered prenatal screening test. Both screen for Down syndrome and trisomy 18. Results from eFTS are available earlier in pregnancy.
A woman who presents to her first prenatal visit at a later gestational age may be offered Multiple Marker Screening .

Common Feelings About Testing
Not everyone who has genetic testing or screening will have the same reaction. People within a family may have very different feelings.
- Some people may worry about what the test result may show, or how they will react to the test result.
- Others may feel relief that they were able to inform themselves. The results of genetic testing may help these people decide what to do next.
- People who are at risk of having a child with a genetic condition may feel anxious or overwhelmed at the thought of passing it onto the next generation.
- Others may be comfortable with the risks but want to learn about their options.
- People undergoing fertility treatments or prenatal testing may feel stress because of the risk of the procedures, the decisions that they may face, the future health of their baby, financial strain, and relationship pressures.
The Conditions For Which Prenatal Screening Is Used
Babies and children with Down syndrome are individuals who are just as unique and highly variable as anyone else. An individual with Down syndrome has an extra copy of chromosome 21 . This usually causes mild to moderate intellectual disability, which means that adults will typically function at the level of an 8-10 year old. An individual with Down syndrome is expected to learn to read and write and to be physically active, however major developmental milestones will be delayed. Individuals with Down syndrome have a greater possibility of health conditions than the average person, such as heart, stomach, bowel, thyroid, vision and hearing problems. Treatment is available for many of these conditions. There is no way to predict how serious or mild these differences will be. People with Down syndrome generally live into their fifties. In general, about one in 1000 babies born has Down syndrome. The chance of having a child with Down syndrome increases with the pregnant person/egg donors age . For more information on Down syndrome, visit the Canadian Down Syndrome Society website.

Asthma Drugs During Pregnancy
Women breathe for two during pregnancy. Each breath they take fuels their bodies with oxygen, but their babies also rely on those breaths for their health and development.
Asthma sparks lung inflammation, which makes breathing difficult. People with asthma may wheeze or gasp for air without medication management. Sometimes, the drugs women use to control asthma symptoms can pass through the umbilical cord to developing babies, and that comes with autism concerns.
In 2016, researchers from Drexel University determined that children born to women who took B2AR drugs for asthma during pregnancy were more likely to have autism than their peers.
- Data collection. Researchers looked at prescriptions filled, not the actual medication used.
- Observational issues. This study looked for connections without specifying a cause and effect.
- Levels of asthma severity. Women who fill these prescriptions may have more significant symptoms than those who dont. That could lead to lower fetal oxygen rates, which could also spark autism.
- Environmental factors. Researchers didnt include data about where the women lived or what other autism triggers were routine for them. A lot of information is then missing.

The Problems With Prenatal Testing For Autism
As prenatal testing improves, it presents a host of thorny issues including what to test, how to interpret the results and what to do about them.
When Maureen Bennies son, Marc, was 10 months old, he started missing developmental milestones. He had had feeding problems since birth and developed a sleep disorder and Bennie quickly grew concerned. I had friends who had children around the same time, she says. He really was a very, very different baby in all regards.
Bennie took Marc to see a doctor but did not come home with a clear diagnosis. And when she got pregnant again when Marc was 17 months old, it didnt cross her mind that the child she was carrying might face similar challenges. Marcs autism diagnosis was confirmed when he was almost 3. His baby sister, Julia, was diagnosed about a year later at 23 months. You just cant believe its happening the second time around. You think: what are the chances? says Bennie, who later founded the Autism Awareness Centre Inc, a company based in Canada.
Bennie wasnt aware then that autism frequently recurs in families: Baby siblings of autistic children are about 20 times more likely than the general population to be diagnosed with the condition. Bennies children were born in the 1990s, and it wasnt until the following decade that scientists learned about baby siblings high odds. Had Bennie known that Marc has autism before her second pregnancy, she says, she might have avoided getting pregnant again.
How Parents Can Spot The Warning Signs
As a parent, youre in the best position to spot the earliest warning signs of autism. You know your child better than anyone and observe behaviors and quirks that a pediatrician, in a quick fifteen-minute visit, might not have the chance to see.

Monitor your childs development. Autism involves a variety of developmental delays, so keeping a close eye on whenor ifyour child is hitting the key social, emotional, and cognitive milestones is an effective way to spot the problem early on. While developmental delays dont automatically point to autism, they may indicate a heightened risk.
Take action if youre concerned. Every child develops at a different pace, so you dont need to panic if your child is a little late to talk or walk. When it comes to healthy development, theres a wide range of typical. But if your child is not meeting the milestones for his or her age, or you suspect a problem, share your concerns with your childs doctor immediately. Dont wait.

Can Reducing Your Exposure To Air Pollution Help
“Perhaps the most convincing and consistent environmental association with autism risk to date is pregnancy exposure to air pollution,” says Dr. Fallin. Multiple studies have shown this connection: One by researchers at the Harvard School of Public Health found that the risk doubled for children born to women exposed to high levels of pollution, particularly in the third trimester. The higher the levels of exposure, the greater the risk.
However, that’s just part of the story.
“The challenge has become understanding what component of air pollution may be relevant, as this implicates hundreds of chemicals from multiple sources,” explains Dr. Fallin. In general, the American Lung Association recommends several ways to protect yourself from air pollution: for instance, fill your gas tank up after dark, exercise away from highly-trafficked areas and, when pollution levels are high, take your workout indoors. You can check out your daily air quality levels at www.airnow.gov.

First-trimester screening includes a test of the pregnant womans blood and an ultrasound exam. Both tests usually are done together between 10 weeks and 13 weeks of pregnancy:
The blood test measures the level of two substances.
The ultrasound exam, called a nuchal translucency screening, measures the thickness of a space at the back of the fetuss neck. An abnormal measurement means there is an increased risk that the fetus has Down syndrome or another type of aneuploidy. It also is linked to physical defects of the heart, abdominal wall, and skeleton.
Second-trimester screening includes the following tests:
The quad or quadruple blood test measures the levels of four different substances in your blood. The quad test screens for Down syndrome, Edwards syndrome , and NTDs. It is done between 15 weeks and 22 weeks of pregnancy.
An ultrasound exam done between 18 weeks and 22 weeks of pregnancy checks for major physical defects in the brain and spine, facial features, abdomen, heart, and limbs.
The results from first-and second-trimester tests can be combined in various ways. Combined test results are more accurate than a single test result. If you choose combined screening, keep in mind that final results often are not available until the second trimester.

What Are The Symptoms Of Autism
Autism usually develops before 3 years of age and affects each individual differently and to varying degrees. It ranges in severity from relatively mild social and communicative impairments to a severe disability requiring lifelong parental, school and societal support.
The hallmark symptom of autism is impaired social interaction. Children with autism may fail to respond to their name and often avoid eye contact with other people. They have difficulty interpreting what others are thinking or feeling because they donât understand social cues provided by tone of voice or facial expressions and they donât watch other peopleâs faces to pick up on these cues.
Many children with autism engage in repetitive movements such as rocking, spinning, twirling or jumping, or in self-abusive behavior such as hand biting or head-banging.
Of children being diagnosed now with an autism spectrum disorder, about half will have intellectual disabilities defined by nonverbal IQ testing, and 25 percent will also develop seizures. Though most children show signs of autism in the first year of life, about 30 percent will seem fine and then regress in both their language and social interactions at around 18 months of age.
About 30 percent of children with autism have physical signs of some alteration in early development such as physical features that differ from their parents , small head size or structural brain malformations.
Very Focused On Or Attached To Unusual Objects
Babies with autism can be very focused on or attached to objects that are unusual for their age, such as long strips of cloth, utensils, chains, rocks, sticks, flowing water, or gadgets they can take apart and put together.
If your child is very focused on or attached to unusual objects, this may be an early sign of autism.
