What is Autism Spectrum Disorder?

Autism Spectrum Disorder (ASD) is a pervasive developmental disorder characterised by impairments in social communication, as well as restricted or repetitive patterns of behaviour, interests and activities. There are also often significant difficulties in the processing of sensory information. These complex and unique behaviours can vary in their manifestation but are representative of the particular diagnostic criteria.

ASD is a lifelong condition. The cause of ASD is currently not known but there is evidence to suggest that genetics play an important role in the cause of ASD. The behaviours and difficulties associated with ASD may be evident very early in an individual’s development, however the stage at which functional impairment becomes obvious can vary. No two individuals with ASD are alike. The behaviours associated with ASD can vary within individuals as they grow and develop and respond to various situations and environments in their daily lives.

Does my child need an assessment?

The following signs could be indicators of ASD which may impact your child’s behaviour and development. No single indicator typically signals ASD, instead a child would present with a number of the following indicators.

Communication:

  • Lack of early gestures such as waving and pointing

  • Lack of response to own name / selective hearing (e.g. responding to environmental sounds but often ignoring speech)

  • Regression in speech and language (e.g. loss of previously used words)

  • Speech absent at 18 months and no use of phrases by 24 months

  • Unusual language patterns (e.g. repetitive speech or jargon)

  • Lack of reciprocal communication

Behaviour:

  • Unusual patterns of behaviours (e.g. flapping hands, spinning, toe walking)

  • Unusual interests

  • Unexplained tantrums

  • Significant difficulties coping with change

  • Ritualised patterns of behaviour

Social / Play:

  • Decreased eye contact

  • Lack of reciprocal smile

  • Lack of interest in others / sharing interest with others

  • Often seeming to be in their ‘own world’ or aloof

  • Preference to playing alone / limited social play

  • Unusual patterns of behaviour in play (e.g. lining objects, categorising)

  • Play is limited to certain toys

  • Lack of imaginary play

Sensory:

  • Over or under reaction to sounds (e.g. afraid of everyday sounds / not responding to own name)

  • Preoccupation with moving or spinning objects

  • Aversion of certain textures or exploring environment through touch

  • Over / under reaction to pain

  • Use of peripheral vision to look at objects / observing or playing with toys on floor / table level

  • Mouthing objects or clothing

What is an Autism Spectrum Disorder Assessment?

In South Australia, a formal ASD diagnosis requires assessment by two accredited clinicians, which can be a psychologist, speech pathologist, psychiatrist or a paediatrician. Assessments can be conducted by a team of two clinicians in one setting or by two individual clinicians across different settings.

Assessments involve interactions with and observations of the child, as well as gathering information from all relevant and available sources about the child’s strengths and difficulties in areas of social communication as well as any restricted and repetitive behaviours, interests or activities. The information is then carefully considered in light of the American Psychiatric Association’s Diagnostic and Statistical Manual – Fifth Edition (DSM-5).

The Assessment Process

A Team ASD Assessment is booked over two sessions. The assessment session typically takes approximately one hour. During this session one of the clinicians performs the parent/caregiver interview, and the other clinician observes the child during play. A feedback session is scheduled later in the day with the parent/caregiver, and usually takes approximately 30 minutes. During this session parents/caregivers will receive feedback about the assessment including a multidisciplinary report discussing the results and recommendations. An expanded comprehensive report may be provided upon request approximately 8-weeks following assessment.

A Single ASD assessment is booked over three sessions. The first assessment session takes up to one hour. During this session the clinician performs the parent/caregiver interview and gathers background information. The second assessment session also takes up to one hour. During this session the clinician observes the child during play. A feedback session is then scheduled with the parents/caregivers. During this session parents/caregivers receive feedback about the assessment and discuss the results and recommendations. A comprehensive report is then completed and issued to the family.

Why is seeking a diagnosis important?

Receiving a diagnosis of ASD provides a profile of an individual’s strengths and areas of development and helps individuals and their families better understand how they function and why they may experience certain difficulties or behaviours. A diagnosis can also allow access to supports and inform appropriate support services.

Has your child had a hearing assessment completed within the last 12 months?

A ‘pass’ in the newborn hearing screening undertaken at birth does not rule out current hearing or ear health issues. Best-practice standards recommend that a child's hearing is screened before any diagnostic assessments (such as evaluations for autism, ADHD, learning difficulties or disorders) or an evaluation of their speech and language skills. This is because an underlying or missed hearing disorder (which is not uncommon in pre- and school-aged children) can influence or potentially change the outcome of these comprehensive evaluations, including:

  • Speech Pathology assessment or intervention

  • Psychoeducational assessments

  • ASD assessments

If you would like to schedule a hearing screen before your child's diagnostic assessment, please speak to one of our friendly team members at Mile End 7123 6147 or Morphett Vale 7123 6163.
