Autism Spectrum Disorder (ASD): Symptoms, limitations and assessments

Published 2 weeks ago par Dr. Yaniv Benzimra , Psychologist

Autism Spectrum Disorder (ASD) can be assessed and diagnosed at any age, from early childhood through adulthood. Early diagnosis and intervention are often emphasized because they can lead to better outcomes and improved quality of life for individuals with ASD and their families.

Autism Spectrum Disorders in Children

For many children, signs of ASD may become apparent during the first two years of life as developmental milestones are missed or delayed. Some children may show early signs such as a lack of social responsiveness, limited eye contact, delayed speech or language development, and repetitive behaviors. In these cases, early screening and assessment for ASD are recommended.

The American Academy of Pediatrics (AAP) recommends that all children be screened for ASD at their 18-month and 24-month well-child visits, as well as at any other appointments where developmental concerns are raised. Early screening tools, such as the Modified Checklist for Autism in Toddlers (M-CHAT), are commonly used to identify children who may be at risk for ASD.

If ASD is suspected based on screening results or developmental concerns, a comprehensive diagnostic evaluation should be conducted ideally by a multidisciplinary team of professionals, including psychologists, pediatricians, speech-language pathologists, and occupational therapists. This evaluation typically involves assessing the child's developmental history, social communication skills, language development, cognitive abilities, sensory processing, and behavior patterns.

Autism Spectrum Disorders in Older Children, Adolescents, and Adults

It's important to note that ASD can also be diagnosed in older children, adolescents, and adults who may not have been identified earlier in life. In these cases, individuals may seek evaluation and diagnosis due to ongoing difficulties with social interaction, communication, sensory sensitivities, executive functioning, and adaptive skills. The age at which ASD is assessed and diagnosed can vary depending on individual circumstances and when concerns are first identified. However, early detection, diagnosis, and intervention can play a crucial role in promoting positive outcomes and providing support to individuals and families affected by ASD.

Diagnostic Evaluation of ASD

Here at Y2 Consulting Psychologists, an analysis of several thousand of our clients reveals that over 5% identify symptoms of ASD as the primary or secondary reason for which they are seeking a psychological assessment or support (counselling or psychotherapy).

As stated, assessment for ASD typically involves a comprehensive evaluation. Here are the key components of a neuropsychological assessment or psychological assessment for ASD:

  • Developmental History: Gathering information about the individual's developmental milestones, early behaviors, medical history, family history, and any concerns or observations from caregivers or teachers.
  • Behavioral Observation: Direct observation of the individual's behavior and interactions in various settings, such as at home, school, or during social activities.
  • Standardized Assessments: Administering standardized assessments and screening tools designed to evaluate social communication skills, language development, cognitive abilities, and adaptive functioning. Examples include the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R).
  • Communication Assessment: Evaluating the individual's language and communication skills, including receptive and expressive language abilities, pragmatics (social use of language), and nonverbal communication skills.
  • Social Skills Assessment: Assessing the individual's social skills and ability to initiate and maintain social interactions, understand social cues, and engage in reciprocal communication with peers and adults.
  • Sensory Profile: Assessing the individual's sensory processing patterns and sensitivities to various sensory stimuli, such as sound, touch, taste, smell, and visual input.
  • Cognitive Assessment: Evaluating cognitive abilities, including intellectual functioning, problem-solving skills, and executive functioning (e.g., attention, planning, organization).
  • Motor Skills Assessment: Assessing gross motor skills (e.g., coordination, balance, movement) and fine motor skills (e.g., hand-eye coordination, handwriting).
  • Behavioral Assessment: Identifying and evaluating any challenging behaviors or repetitive patterns of behavior that may be indicative of ASD, such as stereotyped movements, intense fixations on specific interests, or difficulties with transitions and changes in routine.
  • Parent and Caregiver Interviews: Conducting interviews with parents, caregivers, and other family members to gather information about the individual's behavior, development, and social interactions across different contexts.

Following the assessment process, the assessor (i.e. psychologist) will review the findings, determine whether the individual meets the diagnostic criteria for ASD according to established diagnostic criteria (e.g., DSM-5), and develop recommendations for intervention and support services tailored to the individual's needs. Early intervention and appropriate support services can play a crucial role in maximizing the individual's potential and improving their quality of life.

Possible impacts of ASD on work

ASD can affect an individual's ability to work in various ways, depending on the severity of symptoms, individual strengths, and the nature of the work environment.

Here are some ways in which ASD may impact employment:

  • Social Interaction and Communication Challenges: Many individuals with ASD experience difficulties with social interaction and communication, which can affect their ability to navigate workplace relationships, understand social cues, and communicate effectively with colleagues and supervisors.
  • Sensory Sensitivities: Individuals with ASD may have sensory sensitivities to certain stimuli, such as noise, lights, or textures, which can make it challenging to work in environments with sensory overload or discomfort.
  • Executive Functioning Challenges: Executive functioning difficulties, such as organization, time management, planning, and problem-solving, can impact an individual's ability to handle tasks, prioritize responsibilities, and meet deadlines effectively.
  • Rigid Thinking and Resistance to Change: Some individuals with ASD may have difficulty adapting to changes in routine or unexpected situations, preferring predictability and structure in their work environment.
  • Repetitive Behaviors and Special Interests: Repetitive behaviors or intense fixations on specific topics or interests may interfere with work tasks, distract from job responsibilities, or lead to difficulties with task switching and flexibility.
  • Difficulty with Nonverbal Communication: Challenges with nonverbal communication, such as body language, facial expressions, and tone of voice, may impact an individual's ability to interpret social cues, understand workplace dynamics, and engage in effective teamwork.
  • Job Interview and Job Retention Challenges: Individuals with ASD may encounter challenges during job interviews, such as difficulty with self-presentation, understanding unwritten social rules, and articulating their strengths and abilities. Additionally, maintaining employment may be challenging due to difficulties with workplace social dynamics, sensory sensitivities, or executive functioning challenges.
  • Strengths and Accommodations: Despite the challenges, many individuals with ASD possess unique strengths and talents that can contribute positively to the workplace, such as attention to detail, strong memory, and expertise in specialized areas. Providing accommodations and supports tailored to the individual's needs can help mitigate challenges and optimize job performance.


Overall, while ASD may present challenges in the workplace, with understanding, accommodations, and appropriate support, many individuals with ASD can succeed and thrive in various types of employment. Creating inclusive and supportive work environments that value diversity and accommodate different needs is essential for maximizing the potential of all employees, including those with ASD.
