Signs Of Social Difficulties

What Causes Autism? | Child Psychology
  • Appears disinterested or unaware of other people or whats going on around them.
  • Doesnt know how to connect with others, play, or make friends.
  • Prefers not to be touched, held, or cuddled.
  • Doesnt play pretend games, engage in group games, imitate others, or use toys in creative ways.
  • Has trouble understanding feelings or talking about them.
  • Doesnt seem to hear when others talk to them.
  • Doesnt share interests or achievements with others .

Basic social interaction can be difficult for children with autism spectrum disorder. Many kids on the autism spectrum seem to prefer to live in their own world, aloof and detached from others.

Rates Are On The Rise

An estimated 1 in 40 children in this country have autism to some degree, according to a recent study from Pediatrics based on 2016 data. That’s about 1.5 million children between the ages 3 to 17. Nationwide, autism strikes three to four times more boys than girls the rates are about the same for kids of all races.

Although there seems to be an autism epidemic, the Pediatrics study attributes the increasing prevalence to more inclusive reporting. The definition of autism has been expanded in the past decade to include a wider spectrum of problems with communication and social interaction. “Ten years ago, many children with mild autism were simply not diagnosed,” says Adrian Sandler, M.D., a developmental-behavioral pediatrician at Mission Children’s Hospital, in Asheville, North Carolina, and chair of the American Academy of Pediatrics’ committee on children with disabilities. Plus, there are more state and federal programs for autistic kids, giving doctors an incentive to diagnose and refer them. However, there may be additional, unknown reasons for the spike in autism rates, and researchers are investigating everything from environmental toxins to viruses to food allergies.

Diagnosis Of Autism: What We Do Know

Autistic children benefit from early diagnosis, preferably in the first two years of life. Early diagnosis allows behavioral therapy or other treatments to begin early when it seems to be most effective. If you are concerned about your child, talk to your doctor about a referral to see a specialist who can help determine if follow-up is needed. Signs of autism may include symptoms such as:

  • no babbling or pointing by age 1
  • no single words by 16 months or two-word phrases by age 2
  • no response to name
  • loss of language or social skills
  • poor eye contact

Maintaining A Nutritious Diet

Pregnant women can lower the risk for autism by eating a colorful, organic diet rich in green vegetables and fruits containing antioxidants. At least 80 grams of protein per day from lean sources like turkey, chicken, and nuts is recommended. Many health experts support reducing white foods, including bread and sugar. The U.S. Department of Health and Human Services suggest soon-to-be mothers take 400 to 800 mcg of folic acid. Increasing intake of Vitamin D has been linked to better neurological development in fetuses. Pregnant women should also drink eight glasses of filtered water, limit mercury levels from fish, and increase omega-3s. A modest weight gain of 25 to 35 pounds during pregnancy is optimal.

Autism Causes The Reality

The Vaccine

Nobody has really nailed down the exact cause of autism. Although there are some highly confident studies on causation, most everything you hear is simply speculation and statistics at this point. Some of these studies are well done and have convinced us of some connections. Hopefully, there will be more answers as more studies and trials are implemented going forward.

There has been much speculation about vaccines causing autism. To date, there has been no scientific evidence to back this assumption. There can be possible catalysts to expedite the symptoms, but even that is speculation.

With that in mind, heres what science speculates, so far, as possible causes. This list is in no specific order.

New Research On Autism And Our Environment

Sex hormones, medications, certain metals such as lead, pesticides, and chemicals used to make plastic hard or pliable have long been suspected of having a role in autism. They have not been proven to cause autism, but these are known to trigger or worsen other health problems, including some that affect the brain. Many studies have shown that chemical exposures during development in the womb can have much more serious health effects than the same exposures would in adults.

A large 2014 study investigated the connection between autism and genital malformations using health insurance claims from almost a third of the U.S. population. Like autism, genital malformations are increasing: cases of undescended testicle increased 200% between 1970 and 1993, and the percentage of boys born with a deformity of the penis known as hypospadia doubled. Many studies have shown that these malformations are more common among children whose mothers have high levels of chemicals that affect the hormones in their bodies, such as phthalates which are found in cleaning products, medicines, and personal care products like shampoos and creams The link between these chemicals and genital malformations has surfaced in other studies, particularly those involving women in professions that require working daily with these chemicals.

How Is Autism Spectrum Disorder Treated

There is no cure for autism, but treatment can make a big difference. The younger kids are when they start treatment, the better.

Doctors, therapists, and special education teachers can help kids learn to talk, play, and learn. Therapists also help kids learn about making friends, taking turns, and getting along.

Changing Lifestyle To Prevent Autism

A healthcare professional will not be able to tell whether your child will be autistic or not. So, is there nothing to prevent Autism? Well, its true that you couldnt stop autism but can try adopting healthy habits to reduce its chances to occur. You can adopt a healthy lifestyle to prevent autism and some of them are,

1) Eat healthily, live healthily

Schedule your diet with well-balanced meals with lots of protein, vitamins, and fiber during pregnancy. Have regular check-ups and exercise along with prescribed supplements. This will help you to keep track of your own body as well as the child body. Each and every healthy habit adopted by the mother during pregnancy will eventually result in the childs brain development.

2) Reduce exposure to Air pollution

Air pollution doubles the risk of Autism in the child within the trimester of pregnancy which is concluded by the Harvard school of public health. So, the less exposure to air pollution or staying at home in the polluted area will help to prevent Autism.

3) Regular intake of Folic acid

Every pregnant woman is recommended to consume 400 to 800 mcg of folic acid per day with the doctors prescription. The researchers believe that women consuming less folic acid can lead their child developing Autism symptoms when born.

4) Follow family planning

5) Avoid Alcohol During Pregnancy

6) Stress and anxiety involve the potential risk of Autism

Causes And Risk Factors

Can immunizations cause my child to have Autism?

We do not know all of the causes of ASD. However, we have learned that there are likely many causes for multiple types of ASD. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.

  • Most scientists agree that genes are one of the risk factors that can make a person more likely to develop ASD.4, 19
  • Children who have a sibling with ASD are at a higher risk of also having ASD. 5-10
  • Individuals with certain genetic or chromosomal conditions, such as fragile X syndrome or tuberous sclerosis, can have a greater chance of having ASD. 11-14, 20
  • When taken during pregnancy, the prescription drugs valproic acid and thalidomide have been linked with a higher risk of ASD.15-16
  • There is some evidence that the critical period for developing ASD occurs before, during, and immediately after birth. 17
  • Children born to older parents are at greater risk for having ASD. 18

ASD continues to be an important public health concern. Like the many families living with ASD, CDC wants to find out what causes the disorder. Understanding the factors that make a person more likely to develop ASD will help us learn more about the causes. We are currently working on one of the largest U.S. studies to date, called Study to Explore Early Development . SEED is looking at many possible risk factors for ASD, including genetic, environmental, pregnancy, and behavioral factors.

What Are The Risk Factors For Autism

Risk factors for autism include:

  • Low birth weight
  • Being exposed to a medication called valproate during the mothers pregnancy
  • Older parents

Boys are diagnosed with ASD more often than girls.

Studies have shown that there is no link between vaccines and autism. Learn more about vaccines and autism from theCDC.

Autism Screening And Diagnosis

It can be hard to get a definite diagnosis of autism. Your doctor will focus on behavior and development.

For children, diagnosis usually takes two steps.

  • A developmental screening will tell your doctor whether your child is on track with basic skills like learning, speaking, behavior, and moving. Experts suggest that children be screened for these developmental delays during their regular checkups at 9 months, 18 months, and 24 or 30 months of age. Children are routinely checked specifically for autism at their 18-month and 24-month checkups.
  • If your child shows signs of a problem on these screenings, theyâll need a more complete evaluation. This might include hearing and vision tests or genetic tests. Your doctor might want to bring in someone who specializes in autism disorders, like a developmental pediatrician or a child psychologist. Some psychologists can also give a test called the Autism Diagnostic Observation Schedule .

If you werenât diagnosed with autism as a child but notice yourself showing signs or symptoms, talk to your doctor.

What Is Autism Spectrum Disorder

Autism spectrum disorder refers to a group of complex neurodevelopment disorders characterized by repetitive and characteristic patterns of behavior and difficulties with social communication and interaction. The symptoms are present from early childhood and affect daily functioning.

The term spectrum refers to the wide range of symptoms, skills, and levels of disability in functioning that can occur in people with ASD. Some children and adults with ASD are fully able to perform all activities of daily living while others require substantial support to perform basic activities. The Diagnostic and Statistical Manual of Mental Disorders includes Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorders not otherwise specified as part of ASD rather than as separate disorders. A diagnosis of ASD includes an assessment of intellectual disability and language impairment.

ASD occurs in every racial and ethnic group, and across all socioeconomic levels. However, boys are significantly more likely to develop ASD than girls. The latest analysis from the Centers for Disease Control and Prevention estimates that 1 in 68 children has ASD.

Brain Development And Autism

Autism: Causes, Symptoms and Natural Support Strategies

The brain develops differently in autistic children compared with typically developing children.

In young children, the brain is developing all the time. Every time a child does something or responds to something, connections in the brain are reinforced and become stronger.

Over time, the connections that arent reinforced disappear theyre pruned away as theyre not needed. This pruning is how the brain makes room for important connections those needed for everyday actions and responses, like walking, talking or understanding emotions.

In autistic children, the brain tends to grow faster than average during early childhood, especially during the first three years of life. The brains of autistic babies appear to have more cells than they need, as well as poor connections between the cells.

Also, pruning doesnt seem to happen as much in autistic children. This means that information might be lost or sent through the wrong connections. The lack of pruning might also explain why the brain seems to be growing faster in autistic children than in typically developing children.

Its not yet clear what causes this difference in brain development.

What Is The Difference Between Autism And Autism Spectrum Disorder

The term autism was changed to autism spectrum disorder in 2013 by the American Psychiatric Association. ASD is now an umbrella term that covers the following conditions:

  • Autistic disorder.
  • Pervasive developmental disorder not otherwise specified .
  • Asperger syndrome.

People with ASD have trouble with social interactions and with interpreting and using non-verbal and verbal communication in social contexts. Individuals with ASD may also have the following difficulties:

  • Inflexible interests.
  • Insistence on sameness in environment or routine.
  • Repetitive motor and sensory behaviors, like flapping arms or rocking.
  • Increased or decreased reactions to sensory stimuli.

How well someone with ASD can function in day-to-day life depends on the severity of their symptoms. Given that autism varies widely in severity and everyday impairment, the symptoms of some people arent always easily recognized.

How Can I Find Out What Caused My Childs Autism

There is no known cause of autism spectrum disorder , so there is no way of determining the specific cause of your childs autism. In fact, the generally accepted view is that there is no one specific cause of ASD. Rather, theres a combination of factors that can increase a childs risk.

Genetics and environment are two factors considered to affect the likelihood of a child developing ASD. Genetics may play a strong role, with the risk of a child having a pervasive developmental disorder increasing by 2% 20% if an older sibling has an autism impairment.

Possible environmental causes often involve the childs developing conditions in the womb. For example, the U.S. National Institute of Environmental Health Sciences citesadvanced parental age at time of conception, and prenatal exposure to air pollution or certain pesticides, as two possible risk factors. However, research suggests that environmental factors play a marginal role in whether or not a child will develop autism. Experts instead point to genetics and continue to research exactly which genes mutate and lead to autism.

No matter the potential cause, parents and caregivers must focus on the childs future rather than their past. Available evidence shows that autism tends to develop at an early age, meaning that a child born without autism is unlikely to acquire it when they are older.

What Causes Autism Spectrum Disorder

There is no clear-cut cause of ASD. Some causes that are supported by research include genetic and some environmental factors. Specific genetic causes can only be identified in 10% to 20% of cases. These cases include specific genetic syndromes associated with ASD and rare changes in the genetic code.

Risk factors include older parental age, low birth weight, prematurity and maternal use of valproic acid or thalidomide during pregnancy, among others. This field of study is an active one for reasearch.

Early Treatment Is Crucial

What Causes Autism in Children

There is no known cure for autism, but intensive therapy helps a child learn a wide range of skills from making eye contact to hugging to having a conversation. And the sooner a child begins, the better. A panel of experts convened by the National Academy of Sciences in 2001 recommended that children should have 25 hours of therapy per week as soon as autism is suspected. Because children with autism have very different behaviors and abilities, the most effective approach takes into account a child’s unique challenges and encourages healthy development through play, rather than just trying to change specific symptoms. “Intervention can take many forms, from going to a regular preschool to a parent’s working with her child over the course of a normal day to direct therapies from well-trained teachers and professionals all depending on the child,” Dr. Lord says.

How Does Autism Affect Adults

Families who have autistic loved ones may worry about what life with ASD looks like for an adult.

Some autistic adults go on to live or work independently. Others may require continued aid or support throughout their lives. Each autistic person is different.

Introducing therapies and other remedies early in life can help lead to more independence and better quality of life.

Sometimes autistic people dont receive a diagnosis until much later in life. This is due, in part, to a previous lack of awareness among medical practitioners.

What Can Be Done To Prevent Autism

Although theres currently no cure, studies have found that certain actions can help pregnant women prevent autism. Autism spectrum disorder is a neurological disability that causes significant development delays, especially in social functioning. According to Autism Speaks, one in 45 children in the United States have been diagnosed with autism. New mothers should take preventative steps to increase their chances of delivering a healthy baby. Research in the New England Journal of Medicine found that disparities in brain development begin as early as the second trimester for autistic children. Starting at conception, the following tips can help expectant mothers prevent autism in their growing fetus.

What To Do If Youre Worried

If your child is developmentally delayed, or if youve observed other red flags for autism, schedule an appointment with your pediatrician right away. In fact, its a good idea to have your child screened by a doctor even if he or she is hitting the developmental milestones on schedule. The American Academy of Pediatrics recommends that all children receive routine developmental screenings, as well as specific screenings for autism at 9, 18, and 30 months of age.

Schedule an autism screening. A number of specialized screening tools have been developed to identify children at risk for autism. Most of these screening tools are quick and straightforward, consisting of yes-or-no questions or a checklist of symptoms. Your pediatrician should also get your feedback regarding your childs behavior.
