Symptoms of Autism

  • About Autism

    • Autism spectrum disorder (ASD) is a complex developmental disability.
    • Signs typically appear during early childhood, affect a person’s ability to communicate, and interact with others.
    • Autism is a “spectrum condition” and affects individuals differently and to varying degrees.
    • There is no known single cause of autism
    • Increased awareness and early diagnosis/intervention and access to appropriate services/supports leads to significantly improved outcomes.
    • Some of the behaviors associated with autism include delayed learning of language; difficulty making eye contact or holding a conversation; difficulty with executive functioning, which relates to reasoning and planning; narrow, intense interests; poor motor skills and sensory sensitivities.
    • Again, a person on the spectrum might follow many of these behaviors or just a few, or many others besides.
    • The diagnosis of autism spectrum disorder is applied based on analysis of all behaviors and their severity
    • Autism is treatable. Children do not “outgrow” autism, but studies show that early diagnosis and intervention lead to significantly improved outcomes.
    • In 2018 the Centers for Disease Control and Prevention issued their ADDM autism prevalence report. The report concluded that the prevalence of autism had risen to 1 in every 59 births in the United States based on statistics gathered in  2014.
  • Know the signs: Early identification can change lives

    The characteristic behaviors of autism spectrum disorder may be apparent in infancy (18 to 24 months), but they usually become clearer during early childhood (24 months to 6 years).

    As part of a well-baby or well-child visit, your child’s doctor should perform a “developmental screening,” asking specific questions about your baby’s progress. The National Institute of Child Health and Human Development (NICHD) lists five behaviors that warrant further evaluation:

    • Does not babble or coo by 12 months
    • Does not gesture (point, wave, grasp) by 12 months
    • Does not say single words by 16 months
    • Does not say two-word phrases on his or her own by 24 months
    • Has any loss of any language or social skill at any age

    Any of these five “red flags” does not mean your child has autism. But because the disorder’s symptoms vary so widely, a child showing these behaviors should be evaluated by a multidisciplinary team. This team might include a neurologist, psychologist, developmental pediatrician, speech/language therapist, learning consultant or other professionals who are knowledgeable about autism.

    For more information on developmental milestones, visit the CDC’s “Know the Signs. Act Early” site.

  • Each person with am autism spectrum disorder is different

    Each person with an Autism Spectrum Disorder (ASD) is unique and will have different abilities and disabilities.. Symptoms caused by ASDs might be very mild in one person and more involved in another Individual who is more challenged by  autism.

    • Some individuals challenged by autism, present with a  serious cognitive disability, sensory problems and symptoms of extremely repetitive and unusual behaviors including tantrums, self-injury, defensiveness and aggression. Without appropriate intervention, these symptoms may be very persistent and difficult to change. Living or working with a person significantly disabled  by autism can be very challenging, requiring tremendous patience and understanding of the condition.
    • Individuals with mild autism conditions, however, may seem more like they have personality differences making it challenging to form relationships.

    The primary symptoms of autism include problems with communication and social interaction as well as repetitive interests and activities.

  • Strengths exhibited by some ndividuals with autism

    • Non-verbal reasoning skills
    • Reading skills
    • Perceptual motor skills
    • Drawing skills
    • Computer interest and skills
    • Exceptional memory
    • Visual Spatial abilities
    • Music skills
  • Challenges faced by some individuals with autism

    The above exceptional skills may be combined with subtle or significant delays in other areas of development.  Individuals with the diagnosis may demonstrate some degree of the following:


  • Diagnostic Criteria – DSM-5

    In North America, medical professionals use the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (revised May 2013)  to evaluate autism spectrum disorder (ASD).  For a full copy of this manual, please visit the American Psychiatric Association website.

    In an effort to better understand the differences between the DSM-IV and DSM-5, please watch this wonderful presentation by Doreen Granpeesheh, Ph,D explaining the changes.

    For your convenience, here is the section from the DSM-5 on Autism Spectrum Disorders:


    A. Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history (examples are illustrative, not exhaustive, see text):

    1. Deficits in social-emotional reciprocity, ranging, for example, from abnormal social approach and failure of normal back-and-forth conversation; to reduced sharing of interests, emotions, or affect; to failure to initiate or respond to social interactions.
    2. Deficits in nonverbal communicative behaviors used for social interaction, ranging, for example, from poorly integrated verbal and nonverbal communication; to abnormalities in eye contact and body language or deficits in understanding and use of gestures; to a total lack of facial expressions and nonverbal communication.
    3. Deficits in developing, maintaining, and understanding relationships, ranging, for example, from difficulties adjusting behavior to suit various social contexts; to difficulties in sharing imaginative paly or in making friends; to absence of interest in peers.

    B. Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at At  least two of the following, currently or by history (examples are illustrative, not exhaustive; see text):

    1. Stereotyped or repetitive motor movements, use of objects, or speech (e.g., simple motor stereotypes, lining up toys or flipping objects, echolalia, idiosyncratic phrases).
    2. Insistence on sameness, inflexible adherence to routines, or ritualized patterns or verbal nonverbal behavior (e.g., extreme distress at small changes, difficulties with transitions, rigid thinking patterns, greeting rituals, need to take same route or eat food every day).
    3. Highly restricted, fixated interests that are abnormal in intensity or focus (e.g, strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interest).
    4. Hyper- or hyperactivity to sensory input or unusual interests in sensory aspects of the environment (e.g., apparent indifference to pain/temperature, adverse response to specific sounds or textures, excessive smelling or touching of objects, visual fascination with lights or movement).

    C. Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life).

    D. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.

    E. These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism spectrum disorder and intellectual disability, social communication should be below that expected for general developmental level.

    NOTE: Individuals with a well-established DSM-IV diagnosis of autistic disorder, Asperger’s disorder, or pervasive developmental disorder not otherwise specified should be given the diagnosis of autism spectrum disorder. Individuals who have marked deficits in social communication, but whose symptoms do not otherwise meet criteria for autism spectrum disorder, should be evaluated for social (pragmatic) communication disorder.

  • TABLE 2: Severity Levels for Autism Spectrum Disorders

    Severity is based on social communication impairments and restricted, repetitive patterns of behavior (see Table 2).

    Level 3: “Requiring very substantial support”                                                           

    •  Social Communication: Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning, very limited initiation of social interactions, and minimal response to social overtures from others. For example, a person with few words of intelligible speech who rarely initiates interaction and, when he or she does, makes unusual approaches to meet needs only and responds to only very direct social approaches.
    • Restricted, Repetitive Behaviors:  inflexibility of behavior, extreme difficulty coping with change, or other restricted/repetitive behaviors markedly interfere with functioning in all spheres. Great distress/difficulty changing focus or action.                                                                                                                                                                                                                                        

    Level 2: “Requiring substantial support”        

    • Social Communication:  Marked deficits in verbal and nonverbal social communication skills; social impairments apparent even with supports in place; limited initiation of social interactions; and reduced or  abnormal responses to social overtures from others. For example, a person who speaks simple sentences, whose interaction is limited  to narrow special interests, and how has markedly odd nonverbal communication.
    • Restricted, Repetitive Behaviors: Inflexibility of behavior, difficulty coping with change, or other restricted/repetitive behaviors appear frequently enough to be obvious to the casual observer and interfere with functioning in  a variety of contexts. Distress and/or difficulty changing focus or actions. 

    Level 1: “Requiring support”

    • Social Communication:  Without supports in place, deficits in social communication cause noticeable impairments. Difficulty initiating social interactions, and clear examples of atypical or unsuccessful response to social overtures of others. May appear to have decreased interest in social interactions. For example, a person who is able to speak in full sentences and engages in communication but whose to- and-fro conversation with others fails, and whose attempts to make friends are odd and typically unsuccessful.
    • Restricted, Repetitive Behaviors:  Inflexibility of behavior causes significant interference with functioning in one or more contexts. Difficulty switching between activities. Problems of organization and planning hamper independence.

Diagnosis of Autism

  • Evaluation based on observation

    When parents or support providers become concerned that their child is not following a typical developmental course, they turn to experts, including psychologists, educators and medical professionals, for a diagnosis.

    Some people with autism may appear to have an intellectual disability, sensory processing issues, or problems with hearing or vision. To complicate matters further, these conditions can co-occur with autism.  It is important to distinguish autism from other conditions, as an accurate and early autism diagnosis can provide the basis for an appropriate educational and treatment program.

    Other medical conditions or syndromes, such as sensory processing disorder, can present symptoms that are confusingly similar to autism’s. This is known as differential diagnosis.

    There are many differences between a medical diagnosis and an educational determination, or school evaluation, of a disability. A medical diagnosis is made by a physician based on an assessment of symptoms and diagnostic tests. A medical diagnosis of autism spectrum disorder, for instance, is most frequently made by a physician according to the Diagnostic and Statistical Manual (DSM-5, released 2013) of the American Psychological Association. This manual guides physicians in diagnosing autism spectrum disorder according to a specific number of symptoms.

  • A brief observation in a single setting cannot present a true picture of someone’s abilities and behaviors.

    The person’s developmental history and input from parents, caregivers and/or teachers are important components of an accurate diagnosis.

    An educational determination is made by a multidisciplinary evaluation team of various school professionals. The evaluation results are reviewed by a team of qualified professionals and the parents to determine whether a student qualifies for special education and related services under the Individuals with Disabilities Education Act (IDEA) (Hawkins, 2009).

Co-occuring Conditions

  • There are several medical conditions that have been shown to be significantly more prevalent in those with autism spectrum disorder ASD  than the general population.

    Autism is a whole body disorder diagnosed by what is observable, however these signs and symptoms are often the result of underlying co-occuring conditions.  Knowing what to look for is the first step in getting the most appropriate treatment.

  • Some common co-occuring conditions found in those with autism:

    • Autoimmune conditions
    • Seizure disorders
    • Esophagitis
    • Gastritis
    • Reflux
    • Asthma
    • Eczema
    • Allergies
    • Ear infections
    • Respiratory infections
    • Migraine headaches
    • Allergy disorder (including non IgE-mediated disorders or food intolerances)

    At times, it may be difficult for a health care practitioner to properly assess a patient with an ASD.  The parent or caregiver may not have known to watch for certain signs because they were told that ‘it was just the autism’.  There may be communication barriers or challenging behaviors preventing an obvious observation of a symptom, or perhaps the patient they themselves don’t know where the pain originates from.  It is then that it becomes even more important for the practitioner to be able to recognize some of the behaviors indicating an underlying comorbid condition.

  • Behaviours which may indicate other underlying conditions

    • Sudden changes in behavior
    • Agression
    • Covering ears with hands
    • Loss of acquired skills
    • Irritability or moodiness
    • Frequent night waking or difficulty falling asleep
    • Teeth grinding
    • Walking on toes
    • Tantrums or oppositional behaviour
    • Self-injurious behaviour (biting, hitting, slapping, head-banging, etc.)
    • Chewing on clothes or objects
    • Vocal expressions (moaning, whining, groaning, sighing)
    • Posturing or seeking pressure
    • Repetitive rocking or other movements
  • Common sources of pain and discomfort (chronic, progressive or static)

    • Headache
    • Earache
    • Sore throat
    • Constipation
    • Diarrhea
    • Muscle pain
    • Joint pain

Facts & Statistics

    • About 1 percent of the world population has autism spectrum disorder. (CDC, 2014)
    • Prevalence in the United States is estimated at 1 in 59 births. (CDC, 2014)
    • More than 3.5 million Americans live with an autism spectrum disorder. (Buescher et al., 2014)
    • Prevalence of autism in U.S. children increased by 119.4 percent from 2000 (1 in 150) to 2010 (1 in 68). (CDC, 2014) Autism is the fastest-growing developmental disability. (CDC, 2008)
    • Prevalence has increased by 6-15 percent each year from 2002 to 2010. (Based on biennial numbers from the CDC)
    • Autism services cost U.S. citizens $236-262 billion annually. (Buescher et al., 2014)
    • A majority of costs in the U.S. are in adult services – $175-196 billion, compared to $61-66 billion for children. (Buescher et al., 2014)
    • Cost of lifelong care can be reduced by 2/3 with early diagnosis and intervention. (Autism. 2007 Sep;11(5):453-63; The economic consequences of autistic spectrum disorder among children in a Swedish municipality. Järbrink K1.)
    • 1 percent of the adult population of the United Kingdom has autism spectrum disorder. (Brugha T.S. et al., 2011)
    • The U.S. cost of autism over the lifespan is about $2.4 million for a person with an intellectual disability, or $1.4 million for a person without intellectual disability. (Buescher et al., 2014)
    • 35 percent of young adults (ages 19-23) with autism have not had a job or received postgraduate education after leaving high school. (Shattuck et al., 2012)
    • It costs more than $8,600 extra per year to educate a student with autism. (Lavelle et al., 2014) (The average cost of educating a student is about $12,000 – NCES, 2014)
    • In June 2014, only 19.3 percent of people with disabilities in the U.S. were participating in the labor force – working or seeking work. Of those, 12.9 percent were unemployed, meaning only 16.8 percent of the population with disabilities was employed. (By contrast, 69.3 percent of people without disabilities were in the labor force, and 65 percent of the population without disabilities was employed.) (Bureau of Labor Statistics, 2014)

Screening Tools

  • As Early as 18 months

    Research has found that Autism Spectrum Disorders (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 they are much older. This delay means that children with an ASD might not get the help they need. The earlier an ASD is diagnosed, the sooner treatment can begin.

    Developmental Screening Tools

    Screening tools are designed to help identify children who might have developmental delays. Screening tools do not provide conclusive evidence of developmental delays and do not result in diagnoses. A positive screening result should be followed up with your child’s health care provider immediately if you think something is wrong.

    Types of Screening Tools

    There are many different developmental screening tools that may be admistered by professionals, community service providers and in some cases parents. These include:

    • Ages and Stages Questionnaires (ASQ)
    • Communication and Symbolic Behavior Scales (CSBS)
    • Parent’s Evaluation of Development Status (PEDS)
    • Modified Checklist for Autism in Toddlers (M-CHAT)
    • Screening Tool for Autism in Toddlers and Young Children (STAT)
    • Observation tools such as the Autism Diagnostic Observation Schedule (ADOS-G)
    • The Childhood Autism Rating Scale (CARS)
    • The Autism Diagnostic Interview – Revised (ADI-R)

    This list is not exhaustive, and other tests are available.

    Online Tools

    For your convenience, Autism Canada has four online screening tools available based on the age of the individual being screened.
