Autism Awareness Month

Autism spectrum disorders (ASDs) are a group of developmental disabilities that can cause significant social, communication and behavioral challenges.

ASDs are “spectrum disorders” which means ASDs affect each person in different ways, and can range from very mild to severe. People with ASDs share some similar symptoms, such as problems with social interaction. But there are differences in when the symptoms start, how severe they are, and the exact nature of the symptoms.

Types of ASDs
There are three different types of ASDs:

Autistic Disorder (also called “classic” autism)
This is what most people think of when hearing the word “autism.” People with autistic disorder usually have significant language delays, social and communication challenges, and unusual behaviors and interests. Many people with autistic disorder also have intellectual disability.
Asperger Syndrome
People with Asperger syndrome usually have some milder symptoms of autistic disorder. They might have social challenges and unusual behaviors and interests. However, they typically do not have problems with language or intellectual disability.
Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS; also called “atypical autism”)
People who meet some of the criteria for autistic disorder or Asperger syndrome, but not all, may be diagnosed with PDD-NOS. People with PDD-NOS usually have fewer and milder symptoms than those with autistic disorder. The symptoms might cause only social and communication challenges.

Signs and Symptoms
ASDs begin before the age of 3 and last throughout a person’s life, although symptoms may improve over time. Some children with an ASD show hints of future problems within the first few months of life. In others, symptoms might not show up until 24 months or later. Some children with an ASD seem to develop normally until around 18 to 24 months of age and then they stop gaining new skills, or they lose the skills they once had.

A person with an ASD might:

Not respond to their name by 12 months
Not point at objects to show interest (point at an airplane flying over) by 14 months
Not play “pretend” games (pretend to “feed” a doll) by 18 months
Avoid eye contact and want to be alone
Have trouble understanding other people’s feelings or talking about their own feelings
Have delayed speech and language skills
Repeat words or phrases over and over (echolalia)
Give unrelated answers to questions
Get upset by minor changes
Have obsessive interests
Flap their hands, rock their body, or spin in circles
Have unusual reactions to the way things sound, smell, taste, look, or feel

Diagnosis
Diagnosing ASDs can be difficult since there is no medical test, like a blood test, to diagnose the disorders. Doctors look at the child’s behavior and development to make a diagnosis.

ASDs can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable. However, many children do not receive a final diagnosis until much older. This delay means that children with an ASD might not get the help they need.

Treatment
There is currently no cure for ASDs. However, research shows that early intervention treatment services can greatly improve a child’s development. Early intervention services help children from birth to 3 years old (36 months) learn important skills. Services can include therapy to help the child talk, walk, and interact with others. Therefore, it is important to talk to your child’s doctor as soon as possible if you think your child has an ASD or other developmental problem.

Even if your child has not been diagnosed with an ASD, he or she may be eligible for early intervention treatment services. The Individuals with Disabilities Education Act (IDEA) says that children under the age of 3 years (36 months) who are at risk of having developmental delays may be eligible for services. These services are provided through an early intervention system in your state. Through this system, you can ask for an evaluation.

In addition, treatment for particular symptoms, such as speech therapy for language delays, often does not need to wait for a formal ASD diagnosis.

Causes and Risk Factors
We do not know all of the causes of ASDs. However, we have learned that there are likely many causes for multiple types of ASDs. 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 an ASD.
Children who have a sibling or parent with an ASD are at a higher risk of also having an ASD.
ASDs tend to occur more often in people who have certain other medical conditions. About 10% of children with an ASD have an identifiable genetic disorder, such as Fragile X syndrome, tuberous sclerosis, Down syndrome and other chromosomal disorders.
Some harmful drugs taken during pregnancy have been linked with a higher risk of ASDs, for example, the prescription drugs thalidomide and valproic acid.
We know that the once common belief that poor parenting practices cause ASDs is not true.
There is some evidence that the critical period for developing ASDs occurs before birth. However, concerns about vaccines and infections have led researchers to consider risk factors before and after birth.

ASDs are an urgent public health concern. Just like the many families affected in some way by ASDs, CDC wants to find out what causes the disorder. Understanding the risk factors that make a person more likely to develop an 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). SEED is looking at many possible risk factors for ASDs, including genetic, environmental, pregnancy, and behavioral factors.

Who is Affected
ASDs occur in all racial, ethnic, and socioeconomic groups, but are almost five times more common among boys than among girls. CDC estimates that about 1 in 88 children has been identified with an autism spectrum disorder (ASD).

More people than ever before are being diagnosed with an ASD. It is unclear exactly how much of this increase is due to a broader definition of ASDs and better efforts in diagnosis. However, a true increase in the number of people with an ASD cannot be ruled out. We believe the increase in ASD diagnosis is likely due to a combination of these factors.

Within the past decade, CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network has been estimating the number of people with an ASD in the U.S. We have learned a lot about how many children in the U.S. have an ASD. It will be important to use the same methods to track how the number of people with an ASD is changing over time in order to learn more about the disorders.

If You’re Concerned
If you think your child might have an ASD or you think there could be a problem with the way your child plays, learns, speaks, or acts,contact your child’s doctor, and share your concerns.

If you or the doctor is still concerned, ask the doctor for a referral to a specialist who can do a more in-depth evaluation of your child. Specialists who can do a more in-depth evaluation and make a diagnosis include:

Developmental Pediatricians (doctors who have special training in child development and children with special needs)
Child Neurologists (doctors who work on the brain, spine, and nerves)
Child Psychologists or Psychiatrists (doctors who know about the human mind)

At the same time, call your state’s public early childhood system to request a free evaluation to find out if your child qualifies for intervention services. This is sometimes called a Child Find evaluation. You do not need to wait for a doctor’s referral or a medical diagnosis to make this call.

Where to call for a free evaluation from the state depends on your child’s age:

If your child is not yet 3 years old, contact your local early intervention system.You can find the right contact information for your state by calling the National Dissemination Center for Children with Disabilities (NICHCY) at 1-800-695-0285.Or visit the NICHCY website. Once you find your state on this webpage, look for the heading “Programs for Infants and Toddlers with Disabilities: Ages Birth through 3″.
If your child is 3 years old or older, contact your local public school system.Even if your child is not yet old enough for kindergarten or enrolled in a public school, call your local elementary school or board of education and ask to speak with someone who can help you have your child evaluated.If you’re not sure who to contact, call the National Dissemination Center for Children with Disabilities at 1.800.695.0285 or visit the NICHCY website. Once you find your state on this webpage, look for the heading “Programs for Children with Disabilities: Ages 3 through 5″.

Research shows that early intervention services can greatly improve a child’s development. In order to make sure your child reaches his or her full potential, it is very important to get help for an ASD as soon as possible.

Autism Awareness Month

The importance of recognizing Autism throughout the month of April is to help better educate and raise awareness to the public. Autism is a complex mental condition and developmental disability, characterized by difficulties in the way a person communicates and interacts with other people. Autism can be present from birth or form during early childhood, typically within the first three years. Autism is a lifelong developmental disability with no single known cause.

People with autism are also known as having Autism Spectrum Disorder (ASD) both terms are often used interchangeably. People with ASD have a set of symptoms unique to themselves; no two people are the same. ASD affects people in different ways, and can range from very mild to severe. Although some symptoms are similar, such as challenges with social interaction, there are differences in when the symptoms start, how severe they are, and the exact nature of the symptoms.

If you are looking for a way to get involved, donate for just want to learn more information about Autism you can visit the websites of some great organizations such as Autism Speaks, Autism Society and the National Autism Association.

World Autism Awareness Day: Light It Up Blue

Every April 2, Autism Speaks celebrates World Autism Awareness Day with a global autism awareness campaign called Light It Up Blue. It’s easy (and fun!) to be a part of it — you can do anything from wearing blue to lighting your whole office or school up blue.

Add your name to say you’ll be a part of it, and we’ll be in touch with resources and ideas to get your friends involved. Thanks for helping shine a light on autism.

What Is Autism?
Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. With the May 2013 publication of the DSM-5 diagnostic manual, all autism disorders were merged into one umbrella diagnosis of ASD. Previously, they were recognized as distinct subtypes, including autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome.

ASD can be associated with intellectual disability, difficulties in motor coordination and attention and physical health issues such as sleep and gastrointestinal disturbances. Some persons with ASD excel in visual skills, music, math and art.

Autism appears to have its roots in very early brain development. However, the most obvious signs of autism and symptoms of autism tend to emerge between 2 and 3 years of age. Autism Speaks continues to fund research on effective methods for earlier diagnosis, as early intervention with proven behavioral therapies can improve outcomes. Increasing autism awareness is a key aspect of this work and one in which our families and volunteers play an invaluable role.

What is autism?

Autism spectrum disorder (ASD) is a range of complex neurodevelopment disorders, characterized by social impairments, communication difficulties, and restricted, repetitive, and stereotyped patterns of behavior. Autistic disorder, sometimes called autism or classical ASD, is the most severe form of ASD, while other conditions along the spectrum include a milder form known as Asperger syndrome, and childhood disintegrative disorder and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Although ASD varies significantly in character and severity, it occurs in all ethnic and socioeconomic groups and affects every age group. Experts estimate that 1 out of 88 children age 8 will have an ASD (Centers for Disease Control and Prevention: Morbidity and Mortality Weekly Report, March 30, 2012). Males are four times more likely to have an ASD than females.

What are some common signs of autism?

The hallmark feature of ASD is impaired social interaction. As early as infancy, a baby with ASD may be unresponsive to people or focus intently on one item to the exclusion of others for long periods of time. A child with ASD may appear to develop normally and then withdraw and become indifferent to social engagement.

Children with an ASD may fail to respond to their names and often avoid eye contact with other people. They have difficulty interpreting what others are thinking or feeling because they can’t understand social cues, such as tone of voice or facial expressions, and don’t watch other people’s faces for clues about appropriate behavior. They may lack empathy.

Many children with an ASD engage in repetitive movements such as rocking and twirling, or in self-abusive behavior such as biting or head-banging. They also tend to start speaking later than other children and may refer to themselves by name instead of “I” or “me.” Children with an ASD don’t know how to play interactively with other children. Some speak in a sing-song voice about a narrow range of favorite topics, with little regard for the interests of the person to whom they are speaking.

How is autism diagnosed?

ASD varies widely in severity and symptoms and may go unrecognized, especially in mildly affected children or when it is masked by more debilitating handicaps. Very early indicators that require evaluation by an expert include:

no babbling or pointing by age 1
no single words by 16 months or two-word phrases by age 2
no response to nameA
loss of language or social skills
poor eye contact
excessive lining up of toys or objects
no smiling or social responsiveness.

Later indicators include:

impaired ability to make friends with peers
impaired ability to initiate or sustain a conversation with others
absence or impairment of imaginative and social play
stereotyped, repetitive, or unusual use of language
restricted patterns of interest that are abnormal in intensity or focus
preoccupation with certain objects or subjects
inflexible adherence to specific routines or rituals.

Health care providers will often use a questionnaire or other screening instrument to gather information about a child’s development and behavior. Some screening instruments rely solely on parent observations, while others rely on a combination of parent and doctor observations. If screening instruments indicate the possibility of an ASD, a more comprehensive evaluation is usually indicated.

A comprehensive evaluation requires a multidisciplinary team, including a psychologist, neurologist, psychiatrist, speech therapist, and other professionals who diagnose children with ASDs. The team members will conduct a thorough neurological assessment and in-depth cognitive and language testing. Because hearing problems can cause behaviors that could be mistaken for an ASD, children with delayed speech development should also have their hearing tested.

Children with some symptoms of an ASD but not enough to be diagnosed with classical autism are often diagnosed with PDD-NOS. Children with autistic behaviors but well-developed language skills are often diagnosed with Asperger syndrome. Much rarer are children who may be diagnosed with childhood disintegrative disorder, in which they develop normally and then suddenly deteriorate between the ages of 3 to 10 years and show marked autistic behaviors.

What causes autism

Scientists aren’t certain about what causes ASD, but it’s likely that both genetics and environment play a role. Researchers have identified a number of genes associated with the disorder. Studies of people with ASD have found irregularities in several regions of the brain. Other studies suggest that people with ASD have abnormal levels of serotonin or other neurotransmitters in the brain. These abnormalities suggest that ASD could result from the disruption of normal brain development early in fetal development caused by defects in genes that control brain growth and that regulate how brain cells communicate with each other, possibly due to the influence of environmental factors on gene function. While these findings are intriguing, they are preliminary and require further study. The theory that parental practices are responsible for ASD has long been disproved.

What role does inheritance play?

Twin and family studies strongly suggest that some people have a genetic predisposition to autism. Identical twin studies show that if one twin is affected, there is up to a 90 percent chance the other twin will be affected. There are a number of studies in progress to determine the specific genetic factors associated with the development of ASD. In families with one child with ASD, the risk of having a second child with the disorder is approximately 5 percent, or one in 20. This is greater than the risk for the general population. Researchers are looking for clues about which genes contribute to this increased susceptibility. In some cases, parents and other relatives of a child with ASD show mild impairments in social and communicative skills or engage in repetitive behaviors. Evidence also suggests that some emotional disorders, such as bipolar disorder, occur more frequently than average in the families of people with ASD.

Do symptoms of autism change over time?

For many children, symptoms improve with treatment and with age. Children whose language skills regress early in life—before the age of 3—appear to have a higher than normal risk of developing epilepsy or seizure-like brain activity. During adolescence, some children with an ASD may become depressed or experience behavioral problems, and their treatment may need some modification as they transition to adulthood. People with an ASD usually continue to need services and supports as they get older, but many are able to work successfully and live independently or within a supportive environment.

How is autism treated?

There is no cure for ASDs. Therapies and behavioral interventions are designed to remedy specific symptoms and can bring about substantial improvement. The ideal treatment plan coordinates therapies and interventions that meet the specific needs of individual children. Most health care professionals agree that the earlier the intervention, the better.

Educational/behavioral interventions: Therapists use highly structured and intensive skill-oriented training sessions to help children develop social and language skills, such as Applied Behavioral Analysis. Family counseling for the parents and siblings of children with an ASD often helps families cope with the particular challenges of living with a child with an ASD.
Medications: Doctors may prescribe medications for treatment of specific autism-related symptoms, such as anxiety, depression, or obsessive-compulsive disorder. Antipsychotic medications are used to treat severe behavioral problems. Seizures can be treated with one or more anticonvulsant drugs. Medication used to treat people with attention deficit disorder can be used effectively to help decrease impulsivity and hyperactivity.
Other therapies: There are a number of controversial therapies or interventions available, but few, if any, are supported by scientific studies. Parents should use caution before adopting any unproven treatments. Although dietary interventions have been helpful in some children, parents should be careful that their child’s nutritional status is carefully followed.
