Getting Evaluated For Autism Spectrum Disorder

Autism Spectrum Disorder – Symptoms, Diagnosis, and Treatment

Parent interview In the first phase of the diagnostic evaluation, you will give your doctor background information about your childs medical, developmental, and behavioral history. If you have been keeping a journal or taking notes on anything thats concerned you, share that information. The doctor will also want to know about your familys medical and mental health history.

Medical exam The medical evaluation includes a general physical, a neurological exam, lab tests, and genetic testing. Your child will undergo this full screening to determine the cause of their developmental problems and to identify any co-existing conditions.

Hearing test Since hearing problems can result in social and language delays, they need to be excluded before an Autism Spectrum Disorder can be diagnosed. Your child will undergo a formal audiological assessment where they are tested for any hearing impairments, as well as any other hearing issues or sound sensitivities that sometimes co-occur with autism.

Observation Developmental specialists will observe your child in a variety of settings to look for unusual behavior associated with the Autism Spectrum Disorder. They may watch your child playing or interacting with other people.

Lead screening Because lead poisoning can cause autistic-like symptoms, the National Center for Environmental Health recommends that all children with developmental delays be screened for lead poisoning.

Are Siblings At Greater Risk For Autism Spectrum Disorder

The truth is that genetics do play a role in autism. When one child is diagnosed with ASD, the next child to come along has about a 20% greater risk of developing autism than normal. When the first two children in a family have both been diagnosed with ASD, the third child has about a 32% greater risk of developing ASD.

What Role Do Genes 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, then the other will be affected between 36 to 95 percent of the time. 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 also increases. Many of the genes found to be associated with autism are involved in the function of the chemical connections between brain neurons . Researchers are looking for clues about which genes contribute to increased susceptibility. In some cases, parents and other relatives of a child with ASD show mild impairments in social communication skills or engage in repetitive behaviors. Evidence also suggests that emotional disorders such as bipolar disorder and schizophrenia occur more frequently than average in the families of people with ASD.

Haptics: Touching In Communication

is the study of touching as nonverbal communication, and haptic communication refers to how people and other animals communicate via touching.

Touches among humans that can be defined as communication include , holding hands, kissing , back slapping, , a pat on the shoulder, and brushing an arm. Touching of oneself may include licking, picking, holding, and scratching.:9 These behaviors are referred to as “adapters” or “tells” and may send messages that reveal the intentions or feelings of a communicator and a listener. The meaning conveyed from touch is highly dependent upon the culture, the context of the situation, the relationship between communicators, and the manner of touch.:10

Touch is an extremely important sense for humans as well as providing information about surfaces and textures it is a component of nonverbal communication in interpersonal relationships, and vital in conveying physical intimacy. It can be both sexual and platonic .

Touch is the earliest sense to develop in the fetus. Human babies have been observed to have enormous difficulty surviving if they do not possess a sense of touch, even if they retain sight and hearing. Babies who can perceive through touch, even without sight and hearing, tend to fare much better.

Observance Of Possible Co

Autism

Many studies mention the importance of paying attention to autism symptoms in children with cerebral palsy. Timely diagnosis of autism in a child with cerebral palsy may lead to early intervention which could positively influence the childs developmental trajectory and social functioning.

Cerebral palsy and autism are often diagnosed around the same age in young children. Unfortunately, the fact that these separate conditions share symptoms makes misdiagnosis a possibility. Some feel wide media coverage of autism may skew doctors diagnosis, while others feel more sinister reasons like liability in a medical malpractice claim could lead to a medical professional diagnosing autism rather than cerebral palsy.

In this article, I will examine the incidence and prevalence of cerebral palsy and autism co-occurring in children. I will also look at some of the issues complicating diagnosis and therapy, since standard testing for autism may not be appropriate for children with muscle control and motor function impairments.

What Is The National Autism Spectrum Disorder Surveillance System

NASS is a collaboration of federal, provincial and territorial governments, working to build a comprehensive picture of ASD in Canada. NASS will contribute evidence to help inform critical planning of programs, services and research that impact Canadians living with ASD, their families and caregivers.

Led and coordinated by PHAC, NASS tracks the occurrence and demographic characteristics of children and youth with ASD, including estimates of prevalence, incidence and key characteristics, patterns and trends both over time and across geographic regions. NASS collects, analyzes and reports ASD data from multiple sectors such as health, education and social services.

The key objectives of NASS are to:

  • Estimate how many children and youth in Canada have ASD and how many new cases are emerging over time
  • Describe the population of children and youth in Canada with ASD and compare patterns within Canada and internationally
  • Increase public awareness and understanding and,
  • Inform research, policy and program decision-making.

Limitations Of Asd Levels

Although the ASD levels are useful for indicating autism severity and support needs, the categories aren’t comprehensive. They can be subjective and lacking in nuance, and the DSM-5 offers little specificity regarding the types of support indicated or situations in which support is needed. For example, some autistic people need support at school but are fine at home, while others may do well at school but struggle in social situations.

What’s more, the level a person is assigned when they’re first diagnosed can shift as they develop and refine social skills and as the severity of issues such as anxiety or depression, common among people with autism, fluctuates.

The bottom line: Being assigned one of the three levels of autism can be useful for understanding how high- or low-functioning someone is likely to be and determining what types of services and supports would serve them best. It won’t, however, predict or account for nuances in their personality and behavior, which means the support and services they receive will need to be highly individualized.

Level : Requiring Support

Level 1 ASD is the mildest, or the most “high-functioning,” form of autism. Children with level 1 ASD have a hard time communicating appropriately with others. For example, they may not say the right thing at the right time or be able to read social cues and body language.

A person with ASD level 1 usually is able to speak in full sentences and communicate, but has trouble engaging in back-and-forth conversation with others. They may try to make friends, but not be very successful.

They may also be inflexible in certain ways and have trouble moving from one activity to another. Additionally, they may have problems with organization and planning that prevent them from being as independent as expected for their age.

Related Signs And Symptoms Of Autism Spectrum Disorder

While not part of autisms official diagnostic criteria, children with autism spectrum disorders often suffer from one or more of the following problems:

Sensory problems Many children with autism spectrum disorders either underreact or overreact to sensory stimuli. At times they may ignore people speaking to them, even to the point of appearing deaf. However, at other times they may be disturbed by even the softest sounds. Sudden noises such as a ringing telephone can be upsetting, and they may respond by covering their ears and making repetitive noises to drown out the offending sound. Children on the autism spectrum also tend to be highly sensitive to touch and to texture. They may cringe at a pat on the back or the feel of certain fabric against their skin.

Emotional difficulties Children with autism spectrum disorders may have difficulty regulating their emotions or expressing them appropriately. For instance, your child may start to yell, cry, or laugh hysterically for no apparent reason. When stressed, they may exhibit disruptive or even aggressive behavior . The National Dissemination Center for Children with Disabilities also notes that kids with ASD may be unfazed by real dangers like moving vehicles or heights, yet be terrified of harmless objects such as a stuffed animal.

How It All Fits Together

Diagnosing ASD can be very difficult, mainly because the condition starts to manifest itself early. The families of people living with the condition have to watch for early signs and symptoms in their children from as early as 18 months old.

They should also do a developmental screening test with a certified healthcare professional who will put their child through a series of questionnaires and checklists. An ASD diagnosis helps the families of autistic people understand their needs and how best they can support them.

For an adult who has lived for years with the condition, a diagnosis of ASD could finally answer any questions theyve had for most of their lives. Theyll understand why they find doing certain things harder than most people or find it challenging to communicate with people or be comfortable in social settings.

Paradoxical Reactions To Chemical Substances

Autism Spectrum Disorders and Biochemical Imbalances ...

An additional sign of a structural altered signal processing in the are the more frequently observed in patients with ADD. This are unexpected opposite reactions to what would usually be expected, or other deviating reactions. Substances which play hereby a role are neuroactive substances like local anesthesia , tranquilizers, caffeine, antihistamine, low-potency neuroleptic as well as central and peripheral pain killers. Due to that paradoxical reactions may at least partly have a genetical cause, it may be reasonable to ask in a critical situation, like a surgery, if such reactions occurred in the patient or relatives.

Symptoms Of Autism Spectrum Disorder In Adults

Common symptoms of autism in adults include:

  • Difficulty interpreting what others are thinking or feeling
  • Trouble interpreting facial expressions, body language, or social cues
  • Difficulty regulating emotion
  • Trouble keeping up a conversation
  • Inflection that does not reflect feelings
  • Difficulty maintaining the natural give-and-take of a conversation prone to monologues on a favorite subject
  • Tendency to engage in repetitive or routine behaviors
  • Only participates in a restricted range of activities
  • Strict consistency to daily routines outbursts when changes occur
  • Exhibiting strong, special interests

Autism spectrum disorder is typically a life-long condition, though early diagnosis and treatment can make a tremendous difference.

Restrictive Or Repetitive Activities

Children display preoccupations with unusual subjects and/or in an atypical way, resulting in an all-encompassing obsession with the minutiae of a subject.

It also includes a need for routine, with great upset if this is disrupted. There may be a need for certain rituals to be performed by themselves or others in a specific way as part of this routine .

There may be abnormal preoccupations with toys and other materials for example spinning wheels on cars for the vibration it makes, or licking metal objects.

There may be motor mannerisms with the classical hand-flapping or other such repetitive and compulsive movements, which can occur more when the child is excited or upset.

What Are Some Common Signs Of Asd

Even as infants, children with ASD may seem different, especially when compared to other children their own age. They may become overly focused on certain objects, rarely make eye contact, and fail to engage in typical babbling with their parents. In other cases, children may develop normally until the second or even third year of life, but then start to withdraw and become indifferent to social engagement.

The severity of ASD can vary greatly and is based on the degree to which social communication, insistence of sameness of activities and surroundings, and repetitive patterns of behavior affect the daily functioning of the individual.

Social impairment and communication difficultiesMany people with ASD find social interactions difficult. The mutual give-and-take nature of typical communication and interaction is often particularly challenging. Children with ASD may fail to respond to their names, avoid eye contact with other people, and only interact with others to achieve specific goals. Often children with ASD do not understand how to play or engage with other children and may prefer to be alone. People with ASD may find it difficult to understand other peoples feelings or talk about their own feelings.

Disadvantages Of Nonverbal Communication Across Cultures

Autistic Spectrum Disorder Later Diagnosis

People who have studied in mainly nonverbal communication may not be skilled as a verbal speaker, so much of what they are portraying is through gestures and facial expressions which can lead to major cultural barriers if they have conflict with diverse cultures already. “This can lead to intercultural conflict , misunderstandings and ambiguities in communication, despite language fluency.” Nonverbal communication makes the difference between bringing cultures together in understanding one another, appearing authentic. Or it can push people farther away due to misunderstandings in how different groups see certain nonverbal cues or gestures. From birth, children in various cultures are taught the gestures and cues their culture defines as universal which is not the case for others, but some movements are universal. Evidence suggests humans all smile when happy about something and frowning when something is upsetting or bad.

Cerebral Palsy And Autism Spectrum Disorder

By Yolande Loftus, BA, LLB

When autism is found alongside another disorder, diagnosis and treatment may be complicated. One example is cerebral palsy and autism spectrum disorder, where severity and symptoms tend to present differently in each individual.

Autism rates among children with cerebral palsy are elevated when compared to prevalence in the general population. Even doctors admit the dual diagnosis of cerebral palsy and autism spectrum disorder presents challenges, so its little wonder that parents have questions when symptoms of both conditions are present in their child.

How To Deal With Autism In Adults

Adults with ASD have certain traits which make life difficult for them. They are different.

Which makes it challenging for them to get through their daily life without struggles. But there are ways to work with adults with autism to ensure they receive the best treatment possible.

If you are working with an adult with autism, the first thing to do is to learn and educate yourself about ASD. This will eliminate conflicts in the work environment by minimizing misunderstandings.

Autism causes issues in the individuals communication. Adults with autism who are high-functioning can speak fluently with high level of vocabulary.

But those on the lower part of the spectrum may be non-verbal or may only use sounds to communicate. Make sure that you give these adults sufficient amount of time to communicate and dont force the communication.

Autistic adults may not be able to understand nuances or wordplays while communicating. Try to avoid sarcasm and keep your sentences short and concise.

Sensory overload is a huge problem for individuals with autism. They get overwhelmed with the stimuli in their environment. You may find the situation you are in comfortable, while they get extremely overwhelmed. They do not enjoy certain common physical gestures like hugging or pats on the back. Try to respect and understand their desire for personal space.
