How Do Doctors Diagnose Autism In Children And Adults

The Different Levels/Types of Autism Spectrum Disorder | High Functioning vs Low

The essential features of autism are the significantly impaired or abnormal development of communication and social interaction and the abnormally restricted repertoire of behaviors, activities, and interests. This disturbance in normal development must manifest itself by the time the child is a toddler, prior to age 3. While many parents report normal development in the first year of the child, there is actually limited opportunity to observe this, as the child is often not brought to the attention of a practitioner who has specific experience in diagnosing autism until several years later in many cases. If there is a period of normal development, it cannot extend past age 3. As the early onset of the disorder is a key component in its diagnosis, it is important that practitioners screen for the possible presence of autism in all children from infancy on. As identifying autism as early as possible allows more timely and, therefore, more effective treatment, professionals tend to screen infants and toddlers using a variety of questionnaires, tests, and checklists. Examples of such screening tools include the Checklist for Autism in Toddlers, the Modified Checklist for Autism in Toddlers , the Pervasive Developmental Disorders Screening Test, Second Edition, and the Screening Tool for Autism in Two-Year-Olds.

Autism Symptoms And Screening

It is commonplace to have a family member or close friend with a child diagnosed with one of the autism spectrum disorders . These are a set of neurodevelopmental disabilities affecting young children and adults, which are currently not considered “curable.” The goals of management include minimizing the symptoms and maximizing both independent function and quality of life. These are not uncommon disorders. Their prevalence has been estimated as approximately 6.5 per 1000 children, or 1 in every 150 children. Many believe that there is an “Autism Epidemic.” However, as with many diseases and disorders, there are many reasons for this high prevalence.

Fortunately, significant media coverage and increased research have resulted in a better educated public and more vigilant healthcare practitioners. It is clear that early diagnosis and intervention are associated with better outcomes.

The current Diagnosis and Statistical Manual of Mental Disorders, fifth edition identifies two features that are associated with autism:

  • impairment in social interaction and communication, and
  • repetitive unusual behavior patterns .

Can Autism Go Away With Age

There is no known cure for autism. But recent research might make parents wonder if it ever goes away either through therapy or through a child simply growing older. Around 13 percent of these children lost the diagnosis later meaning they no longer had signs and symptoms that fit on the autism spectrum.

Thimerosal And The Asd Hypothesis

Thimerosal is a mercury-containing compound that has been used as an additive to vaccines to prevent bacterial contamination. In 1997, the United States Food and Drug Administration called for assessment of the risk of all mercury-containing foods and drugs. This action stimulated the United States Public Health Service and the American Academy of Pediatrics to issue a joint statement in 1999 calling for the removal of thimerosal from the vaccines. This action was undertaken as a precautionary measure. There was no evidence that mercury was harmful at the doses being administered in the vaccines. The evidence from these studies does not support and favors rejection of a causal relationship between thimerosal-containing vaccines and autism., Further evidence contradicting this hypothesis is that rates of autism have continued to increase despite the removal of thimerosal from vaccines in 1999.,

5 Types of Autism Spectrum Disorders

What are the different types of autism? No really, what are the different types of autism? This isnt a rhetorical question because after spending this week searching for a definitive answer as to what the different types of autism are, I have come away with the suspicious feeling that, if were honest, no one knows for sure.

Nevertheless, depending on your location in the world and what diagnosis criteria you are using, knowing the different types of autism is a must for finding the correct support. This is why, today, I have done my best to pull together a full list of the different types of autism, as well as where and why a condition finds itself on this ever-changing spectrum.

What Is The Prognosis For Children And Adults With Autism

Persons with autism seem to have a higher mortality rate at younger ages compared to average individuals. This is particularly true for mortality that is related to seizures or infection. It is, therefore, important for the autistic population to receive good medical care from health care professionals who have knowledge and experience in addressing their unique medical needs.

Due to a number of potential factors, autistic persons tend to be vulnerable to nutritional problems. Specifically, factors like variations in appetite, refusal of many foods, food allergies, and side effects to some medications can disproportionately impact the food intake, and therefore, the nutritional status of this population. Individuals with autism have been found to be vulnerable to respiratory problems as well, which results in this population having more doctors’ visits than people who do not have autism. As people with autism also are vulnerable to emotional struggles like anxiety, depression, and attention problems, the help of mental health professionals should be sought when appropriate.

Childhood Disintegrative Disorder/hellers Syndrome/regressive Autism

Okay, so Im not going to sugar coat it, those who have found a place on the spectrum due to this last PDD: Childhood Disintegrative Disorder have often been given a raw deal. This is because, those who have CDD, will usually experienece an unimaginable level of distress between the ages of 0-3 when, seemingly out of nowhere, the condition kicks in, causing a quick regression of social and motor skills to the point where sensory processing are often worse than the average autists.

Social Communication / Interaction Behaviors May Include:

  • Making little or inconsistent eye contact
  • Tending not to look at or listen to people
  • Rarely sharing enjoyment of objects or activities by pointing or showing things to others
  • Failing to, or being slow to, respond to someone calling their name or to other verbal attempts to gain attention
  • Having difficulties with the back and forth of conversation
  • Often talking at length about a favorite subject without noticing that others are not interested or without giving others a chance to respond
  • Having facial expressions, movements, and gestures that do not match what is being said
  • Having an unusual tone of voice that may sound sing-song or flat and robot-like
  • Having trouble understanding another persons point of view or being unable to predict or understand other peoples actions

Level 1 Asd: Requiring Support

Ask Dr. Doreen: How Many Types of Autism are There?

Level 1 ASD is the least severe. This could be viewed as mild autism.

People who qualify as having Level 1 ASD may struggle in social situations and have some concerns with restrictive or repetitive behaviors but they only require minimal support to help them function in their day to day activities.

People with Level 1 ASD are likely able to communicate verbally. They may be able to have some relationships. However, they may struggle maintaining a conversation and making and keeping friends may not come easily or naturally to them.

People with Level 1 ASD may prefer to stick to established routines and feel uncomfortable with changes or unexpected events. They may want to do certain things in their own way.

What Are The Different Types Of Autism

Autism Spectrum Disorder is a developmental disorder that affects communication and behavior in one out of every fifty nine individuals. More specifically, it affects an individuals social communication and interaction skills, and their behaviors. Many individuals who present with Autism show repetitive patterns of behavior, restricted areas of interest, insistence on sameness, and hyper or hypo-sensitivity to environmental stimuli. Describing Autism cannot get much more specific though, because every case varies. For this reason, individual cases are diagnosed on a spectrum of symptoms and severity. By default all of our minds work differently, and those diagnosed with ASD have an excess of neurons around the part of the brain that digests emotions. Since each case of ASD could have a differently altered brain, each person with ASD has different programmed emotional responses to external stimuli.

Just like an individuals symptoms, an Autistic persons progression and treatment depends on a lot of variables. Cases range from non-verbal children blooming late into high-functioning members of the workforce to adults who grow up requiring care from professionals or family members after parents can no longer continue to. The individualized nature of Autism Spectrum Disorder maintains a wide range of cases and requires individualized attention from professionals and family.

Restricted Or Repetitive Behaviors Or Interests

People with ASD have behaviors or interests that can seem unusual. These behaviors or interests set ASD apart from conditions defined by only problems with social communication and interaction.

Examples of restricted or repetitive interests and behaviors related to ASD can include:

  • Lines up toys or other objects and gets upset when order is changed
  • Repeats words or phrases over and over
  • Plays with toys the same way every time
  • Is focused on parts of objects
  • Gets upset by minor changes
  • Has obsessive interests
  • Flaps hands, rocks body, or spins self in circles
  • Has unusual reactions to the way things sound, smell, taste, look, or feel

The Five Types Of Aspergers

It still pisses me off that the DSM5 got rid of Aspergers. Not only is Aspergers its own thing but theres differentlevels of it. There areso many genes that go into autism that it might even be split into several different disorders someday. Heres a totallyunscientific set of types based on aspies Ive known:


These aspies are run by their ids. Theyre the most high-energy and the most likely to blurt out rude shit.Most prone to repetitive behaviors. Also more likely to showtheir feelings than other types. Prone to addictions from Internet browsing to heroin. They usually have more social awareness than theyre given credit for. They can evenbe charismatic for short periods of time, which makes sense because theyre generally the most social. But theyre the hardest aspies to spend extended periods of time with. They used to let their inner monologue run wild when they were younger, driving people away. They may or may not have learned better. Most have developed some pride in their inadvertent tell it like it is attitude, whichis appreciated by certain people. Misdiagnoses include ADHD, bipolar disorder, & borderline.

Is Rett Syndrome Autism

Do I Have Autism? Life On The (SPECTRUM)

Rett syndrome or Rett disorder has also been called autism-dementia-ataxia-loss of purposeful hand use syndrome.

But its not included on the autism spectrum. Its a brain disorder caused by genetic mutations.

Classic Rett syndrome usually affects girls who display typical development for the first few months. Then, symptoms start to appear, involving issues with:

  • language and communication

If you think your child might have symptoms of autism, speak with their pediatrician or a primary care physician. They can refer you to the appropriate specialist, such as a:

You can also request an evaluation from your states public early childhood assistance center. Its free, and you dont need a doctors referral or diagnosis. Your local public school district can also provide assistance.

Theres no one medical test to diagnose autism spectrum disorder. A doctor can make the diagnosis with a comprehensive behavior evaluation and developmental screening.

Some people on the spectrum need minimal support services. Others require a lot. Either way, early intervention is associated with long-term positive effects.

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.

Level : Requiring Very Substantial Support

The communication issues a person with Level 3 ASD may face include:

  • severe issues in both verbal and nonverbal social communication, which severely impair functioning
  • very limited initiation of social interactions
  • minimal response to social interaction from others
  • using few words of intelligible speech
  • unusual methods of meeting social needs and responding to only very direct approaches

The repetitive behavioral issues a person with Level 3 ASD may face include:

  • inflexible behavior

The levels of ASD correspond to the severity of the autism symptoms described above and the degree of support required.

In addition, it is important to keep in mind that the amount of support an autistic person needs can vary according to different ages or situations.

What Parents Should Know About An Asd Diagnosis

While doctors will generally now diagnose someone with ASD and a level, doctors might still refer back to pre-2013 diagnoses in an informal way, especially if they are trying to help a family better understand the kind of support their child might need, according to Frazier.

For instance, when Huftons older son was diagnosed, her childs psychologist told her that he was considered low-functioning because he required so much assistance to make it through the day. But when her younger son was diagnosed two years later, she had come to focus less on labels and more on her sons unique traits.

Given her experience, Hufton encourages parents to consider their child as an individual. My childrens future is not based on where they fall on the spectrum, she says. My childrens future is based on what we help them achieve. What their interests are and what their strengths are. The extra labels have nothing to do with that. As a parent, I advocate for them to get accommodations and services that will help them based on what I observe about them individually.

When it comes to fixating on a specific label, Shore couldnt agree more. Its up to educators, therapists, parents and others in allied fields to avoid thinking of autism as a series of deficits, disorders and disabilities, Shore says. The potential of people on the autism spectrum is the same as everyone else: unlimited.

Why The Old Definitions Of Autism Were Flawed

The 3 Autism Therapy-types (Part 1)

The old autism subtypes did recognize that autism is very much a spectrum disorder, meaning different people experience different symptoms. But, there was a lot of grey area in determining what symptoms were most important for putting any one individual into one category versus the other. Veenstra-Vanderweele adds: The shift to a single diagnosis of autism spectrum disorder reflects the reality that we dont know how to split up the disorder into groups of people.

The definitions of those four subtypes of autism help elucidate why the distinctions were not always clear and where there was overlap between the criteria for the different subtypes:

Autistic Disorder This had been the broadest subtype of autism. Some considered it to characterize the classic case of autism. Symptoms could include any combination of language challenges, repeating specific behaviors, learning disabilities, or problems with speech and nonverbal communication. One individual with this diagnosis might have also had very unique strengths and differences from others.

Some of these people really have very specific interests that some might label as obsessive, Veenstra-Vanderweele says. Others categorized in this way might be unable to leave behind a topic in conversation, he adds.

Pervasive Developmental Disorder Not Otherwise Specified

This refers to a series of disorders that include delays in development, including social development, communication, and the ability to use their imagination. Parents might notice a problem when their toddler is not walking, talking or developing well.

Symptoms: Children with this type of autism will have delays in stages of development, especially communication and social development. They might be confused about the world around them and have trouble understanding how it works.

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.
