Is There any FDA Approved Treatment for Autism?

According to FDA (as on 4/17/2019), Products or treatments claiming to cure autism are deceptive and misleading, because there is no cure for autism. The same is true of many products claiming to “treat” autism or autism-related symptoms. Some may carry significant health risks.

The Food and Drug Administration (FDA) plays an important role in warning companies against making improper claims about their products’ intended use as a treatment or cure for autism or autism-related symptoms.

About Autism

According to the Centers for Disease Control and Prevention (CDC), about 1 in 68 children has been identified with an autism spectrum disorder (ASD). Autism spans all racial, ethnic and socioeconomic groups, and is about 4 times more common among boys (1 in 42) than among girls (1 in 189).

The National Institutes of Health (NIH) describe children with autism as having difficulties with social interaction, displaying problems with verbal and nonverbal communication, exhibiting repetitive behaviors and having narrow, obsessive interests. These behaviors can range in impact from mild to disabling. Some children with ASD are very high functioning, while others may have significant delays in cognition and development.

Because there can be overlap in symptoms between ASD and other disorders, such as attention deficit hyperactivity disorder (ADHD), it’s important that the treatment focus on a person’s specific needs. Existing behavioral interventions are designed to address specific symptoms, particularly communication issues, and can bring about improvement. Early intervention is key.

There are FDA-approved drugs that can help some people manage related symptoms of ASD. For example, the FDA has approved the use of antipsychotics such as risperidone (for patients ages 5 to 16) and aripripazole (for patients ages 6 to 17) to treat irritability associated with autistic disorder. Before using any behavioral intervention or drug therapy that claims to treat or cure autism, you should check with your health care professional.

FDA Cracks Down on False Claims

The Food and Drug Administration has warned and/or taken action against a number of companies that have made improper claims about their products’ intended use as a treatment or cure for autism or autism-related symptoms. Some of these so-called therapies carry significant health risks.

For example,

  • “Chelation Therapies.” These products claim to cleanse the body of toxic chemicals and heavy metals by binding to them and “removing” them from circulation. They come in a number of forms, including sprays, suppositories, capsules, liquid drops and clay baths. FDA-approved chelating agents are approved for specific uses that do not include the treatment or cure of autism, such as the treatment of lead poisoning and iron overload, and are available by prescription only. FDA-approved prescription chelation therapy products should only be used under professional supervision. Chelating important minerals needed by the body can lead to serious and life-threatening outcomes.
  • Hyperbaric Oxygen Therapy. This involves breathing oxygen in a pressurized chamber and has been cleared by FDA only for certain medical uses, such as treating decompression sickness suffered by divers.
  • Detoxifying Clay Baths. Added to bath water, these products claim to draw out chemical toxins, pollutants and heavy metals from the body. They are improperly advertised as offering “dramatic improvement” for autism symptoms.
  • Various products, including raw camel milk, MMS (chlorine dioxide) and essential oils. These products have been marketed as a treatment for autism or autism-related symptoms, but have not been proven safe and effective for these advertised uses.

FDA some quick tips to help you identify false or misleading claims.

  • Be suspicious of products that claim to treat a wide range of diseases.
  • Personal testimonials are no substitute for scientific evidence.
  • Few diseases or conditions can be treated quickly, so be suspicious of any therapy claimed as a “quick fix.”
  • So-called “miracle cures,” which claim scientific breakthroughs or contain secret ingredients, are likely a hoax.

If you have a question about treatment, talk to a health care provider who specializes in caring for people with ASD.

Is There any Connection Between Vaccines and Autism?

Many people have had concerns that Autism (ASD) might be linked to the vaccines children receive, but studies have shown that there is no link between receiving vaccines and developing ASD. A recent study in 2019 has revealed that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, or is not associated with clustering of autism cases after vaccination.

In 2011, an Institute of Medicine (IOM) reportExternal on eight vaccines given to children and adults found that with rare exceptions, these vaccines are very safe.

ExternCDC study in 2013 added to the research showing that vaccines do not cause ASD. The study looked at the number of antigens (substances in vaccines that cause the body’s immune system to produce disease-fighting antibodies) from vaccines during the first two years of life. The results showed that the total amount of antigen from vaccines received was the same between children with ASD and those that did not have ASD.

One vaccine ingredient that has been studied specifically is thimerosal, a mercury-based preservative used to prevent contamination of multidose vials of vaccines. Research shows that thimerosal does not cause ASD. In fact, a 2004 scientific reviewExternal by the IOM concluded that “the evidence favors rejection of a causal relationship between thimerosal–containing vaccines and autism.” Since 2003, there have been nine CDC-funded or conducted studies Cdc-pdf[PDF – 357 KB] that have found no link between thimerosal-containing vaccines and ASD, as well as no link between the measles, mumps, and rubella (MMR) vaccine and ASD in children.

Between 1999 and 2001, thimerosal was removed or reduced to trace amounts in all childhood vaccines except for some flu vaccines. This was done as part of a broader national effort to reduce all types of mercury exposure in children before studies were conducted that determined that thimerosal was not harmful. It was done as a precaution. Currently, the only childhood vaccines that contain thimerosal are flu vaccines packaged in multidose vials. Thimerosal-free alternatives are also available for flu vaccine. For more information, see the Timeline for Thimerosal in Vaccines.

Besides thimerosal, some people have had concerns about other vaccine ingredients in relation to ASD as well. However, no links have been found between any vaccine ingredients and ASD.

What is Autism?

Autism Spectrum Disorder (ASD) or simply Autism 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.

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 59 [Ref 1] children has ASD.

Do symptoms of autism change over time?

People often ask if symptoms of autism change over time. For many children, symptoms improve with age and behavioral treatment. During adolescence, some children with Autism Spectrum Disease (ASD) may become depressed or experience behavioral problems, and their treatment may need some modification as they transition to adulthood. People with ASD usually continue to need services and supports as they get older, but depending on severity of the disorder, people with ASD may be able to work successfully and live independently or within a supportive environment.

What is the Autism Prevalence in the US?

The federal government’s Centers for Disease Control and Prevention (CDC) estimates that about 1 in 59 children has been identified with Autism Spectrum Disorder (ASD) (or 16.8 per 1,000 8-year-olds) in the United States. These autism prevalence estimates from the Autism and Developmental Disabilities Monitoring (ADDM) Network are based on data collected from health and special education records of children living in 11 communities across the United States during 2014. These 11 communities comprised 8% of the United States population of 8-year-olds in 2014. Information was collected on children who were 8 years old because previous work has shown that, by this age, most children with ASD have been identified for services. The Autism and Developmental Disabilities Monitoring (ADDM) Network is the only collaborative network to track the number and characteristics of children with autism spectrum disorder (ASD) in multiple communities in the United States.

Current ADDM Network Sites - Autism Prevalence

Source: CDC

In 2007, CDC’s ADDM Network first reported that about 1 in 150 children had ASD (based on 2002 data from 14 communities). Then, in 2009, the ADDM Network reported that 1 in 110 children had ASD (based on 2006 data from 11 communities). And, in 2012, the ADDM Network reported that 1 in 88 children had ASD (based on 2008 data from 14 communities). In 2014, the ADDM Network reported that about 1 in 68 children had ASD (based on 2010 data from 11 communities). The estimated autism prevalence stayed about the same between 2010 and 2012, as reported in 2016.

Autism Prevalence in Arizona

  • About 1 in 71 children has been identified with Autism Spectrum Disorder (ASD) (or 14.0 per 1,000 8-year-olds) in Arizona in 2014.
  • Fewer than half of the children identified with ASD received a comprehensive developmental evaluation by 3 years of age despite concerns about developmental delays. This lag between first concern and first developmental evaluation leads to delays in diagnosis and connection to the services and support the children need.
  • Although ASD can be diagnosed as early as 2 years of age, in Arizona, the median age of diagnosis by a community provider is 4 years and 8 months of age.
  • Differences between the percentage of boys and girls identified with ASD continue. It may be that boys are at greater risk for ASD, and/or it may be that girls are under-identified due to other factors.
  • Hispanic children are less likely to be identified with ASD compared to non-Hispanic children in Arizona. This may reflect cultural differences, socioeconomic differences, and/or differences in access to diagnostic and therapeutic services.
  • More children with average intelligence levels are being identified with ASD. This may reflect increased awareness of the signs of autism, differentiated from other developmental disabilities.

Autism Prevalence in Arkansas

  • About 1 in 77 children has been identified with Autism Spectrum Disorder (ASD) in Arkansas in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • Differences between the percentage of boys and girls identified with ASD continue. It may be that boys are at greater risk for ASD and/or it may be that girls are under-identified due to others factors, such as how providers diagnose and document ASD symptoms among boys versus girls.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were diagnosed with ASD by a community provider by 4 years, 11 months of age.
  • Efforts may be directed toward evaluating and diagnosing all children with ASD as early as possible so that they can be connected to the services they need.

Autism Prevalence in Colorado

  • About 1 in 72 children has been identified with Autism Spectrum Disorder (ASD) in Colorado in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • Hispanic children were less likely to be identified with ASD than white or black children. Research does not show that being Hispanic makes a child less likely to develop ASD. This difference in identification may reflect cultural and/or socioeconomic differences, such as delayed or lack of access to services, as compared to other groups in Colorado.
  • Despite the developmental concerns noted in many of the children’s records by 3 years of age, less than half of children identified with ASD received a comprehensive developmental evaluation by this same age. The lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • Although ASD can be diagnosed as early as 2 years of age, about half of children were not diagnosed with ASD by a community provider until after age 4 years and 3 months. Of the children identified with ASD in Colorado through the CO-ADDM Project, only 58 percent had either eligibility for autism special education services or a clinical autism diagnosis documented in their records.

Autism Prevalence in Georgia

  • About 1 in 59 children has been identified with Autism Spectrum Disorder (ASD) in Georgia in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • The proportion of black and white children identified with ASD was about the same. However, Hispanic children were less likely to be identified with ASD than black or white children. This may reflect cultural and/or socioeconomic differences, such as language barriers and delayed or lack of access to services, as compared to white and black children in Georgia.
  • Though developmental concerns were noted in many children’s records by 3 years of age, less than half of children identified with ASD received a comprehensive developmental evaluation by this same age. The lag between first concern and first developmental evaluation may affect when children are diagnosed and connected to the services they need.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were not diagnosed with ASD by a community provider until after 4 years, 5 months of age.
  • Efforts may be directed toward evaluating and diagnosing all children with ASD as early as possible so that they can be connected to the services they need.

Autism Prevalence in Maryland

  • About 1 in 50 children has been identified with Autism Spectrum Disorder (ASD) in Maryland in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • The percentage of children with ASD is high in this area of Maryland.
  • Differences between the percentage of boys and girls identified with ASD continue. It may be that boys are at greater risk for ASD and/or it may be that girls are under-identified due to others factors, such as how providers diagnose and document ASD symptoms among boys versus girls.
  • Despite the developmental concerns noted in many (92 percent) of the children’s records by 3 years of age, only slightly more than half (56 percent) of children identified with ASD received a comprehensive developmental evaluation by this same age. The lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were diagnosed with ASD by a community provider by 4 years, 4 months of age.
  • Efforts may be directed toward evaluating and diagnosing all children with ASD as early as possible so that they can be connected to the services they need.

Autism Prevalence in Minnesota

  • About 1 in 42 children has been identified with Autism Spectrum Disorder (ASD) in Minnesota in 2014.
  • This is the first time MN has been a part of the ADDM network, and we are building our geographic area. The findings in this report reflect a small number of children concentrated in a large metropolitan area. The higher prevalence estimate is not unanticipated for a large metropolitan area.
  • In MN there were differences between percentage of boys and girls identified, with more boys than girls. This is consistent with previous estimates.
  • We found varying prevalence rates across racial and ethnic groups in Minnesota. The small number of children in some of these groups makes it difficult to determine whether the rates of children with autism truly are different across groups. As the geographic area for MN-ADDM grows, we will be better able to judge whether there are true differences in prevalence estimates. If differences are found, it will be important to focus on general health disparities that may influence these differences.
  • In Minnesota, we identify autism much later than when first concerns are reported. The lag between first concern and diagnosis is concerning due to what we know about the importance of early intervention.

Autism Prevalence in Missouri

  • About 1 in 71 children has been identified with Autism Spectrum Disorder (ASD) in Missouri in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • Differences between the percentage of boys and girls identified with ASD continue. It may be that boys are at greater risk for ASD and/or it may be that girls are under-identified due to others factors, such as how providers diagnose and document ASD symptoms among boys versus girls.
  • Despite the developmental concerns noted in many of the children’s records by 3 years of age, less than half of children identified with ASD received a comprehensive developmental evaluation by this same age. The lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • Efforts may be directed toward evaluating and diagnosing all children with ASD as early as possible so that they can be connected to the services they need.

Autism Prevalence in New Jersey

  • About 1 in 34 children has been identified with Autism Spectrum Disorder (ASD) in New Jersey in 2014.
  • The percentage of children with ASD increased in New Jersey, from about 2.5 percent in 2012 to about 3 percent, in 2014. Rising numbers of children with ASD need services and support, now, and will require significant resources as they grow into adolescence and adulthood.
  • Boys continue to have a higher ASD prevalence than girls. In 2014, almost 4 percent of boys in the area were identified with ASD, compared to about 1 percent of girls.
  • ASD prevalence in New Jersey did not vary by race or ethnicity in 2014, unlike in 2012, suggesting that progress has been made in identifying all children with ASD.
  • In spite of the fact that developmental concerns are noted in many of children’s records by 3 years of age, fewer than half of children with ASD received a comprehensive developmental evaluation by this same age. This lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were not diagnosed with ASD by a community provider until after 4 years of age.
  • Future efforts may emphasize the importance of screening young children with standard tools and connecting families to needed services before 3 years of age.
  • The percentage of children with ASD continues to be higher in New Jersey compared to other areas in the United States where CDC tracks ASD. It is not known exactly why this is so, but geographic differences in evaluation and diagnostic practices for children with developmental concerns may play a role.

Autism Prevalence in North Carolina

  • About 1 in 57 children has been identified with Autism Spectrum Disorder (ASD) in North Carolina in 2014.
  • Many children are living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • Hispanic children were less likely to be identified with ASD than white or black children. This may reflect cultural and/or socioeconomic differences, such as delayed or lack of access to services, as compared to other groups in North Carolina.
  • Among the areas where CDC tracks ASD across the United States, the area in central North Carolina had the highest percentage of children identified with ASD who had received a comprehensive developmental evaluation by 3 years of age. This is good news, but there is still more to be done to ensure that all children are evaluated as soon as concerns about their development are identified.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were not diagnosed with ASD by a community provider until after 3 years, 4 months of age.
  • Efforts may be directed toward evaluating and diagnosing all children with ASD as early as possible so that they can be connected to the services they need.

Autism Prevalence in Tennessee

  • About 1 in 64 children has been identified with Autism Spectrum Disorder (ASD) in Tennessee in 2014.
  • There are many children living with ASD who need services and support, now and as they grow into adolescence and adulthood.
  • This is the first time data from ADDM are available for TN. The percentage of children with ASD in TN (1.6 percent) was very similar to current estimates across the United States (1.7 percent).
  • Despite the developmental concerns noted in many of the children’s records by 3 years of age, only about one-third (34 percent) of children with ASD received a comprehensive evaluation by this same age. This gap between early concerns and first developmental evaluation may affect when children are diagnosed and the intervention services they need.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were not diagnosed with ASD by a community provider until after 4 years, 8 months of age.

Autism Prevalence in Wisconsin

  • About 1 in 71 children has been identified with Autism Spectrum Disorder (ASD) in Wisconsin in 2014.
  • The percentage of children with ASD increased in southeastern Wisconsin from about 1.1 percent in 2012 to about 1.4 percent in 2014.
  • Hispanic and black children were less likely to be identified with ASD than white children. This may reflect cultural and/or socioeconomic differences, such as delayed or lack of access to services, as compared to white children in Wisconsin.
  • Despite the developmental concerns noted in many of the children’s records by 3 years of age, less than half of children identified with ASD received a comprehensive developmental evaluation by this same age. The lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • Efforts may be directed toward early developmental screening of all children so those who have ASD can be identified early and connected to the services they need.
