Key Facts about Early Diagnosis of Autism Spectrum Disorder (ASD)

By November 9, 2020NESCA Notes 2020

By Renée Marchant, Psy.D.
Pediatric Neuropsychologist

Early diagnosis is a catalyst for propelling children on positive trajectories. If a family and child identify and focus on areas of growth earlier rather than later, there is more time and more possibility of change and improvement. This tenant is particularly critical for diagnosing ASD in toddlerhood and early childhood.

Here are critical facts about the diagnosis of ASD in early childhood and the positive impact of early diagnosis on youngsters as they age into adulthood.

  1. Most children with ASD are not diagnosed until approximately 4 years-old, yet ASD can be reliably identified by the age of 2. There is also expanding research on early identification of infants who may be at risk for ASD. Early detection is possible.
  2. Genes play an important role in ASD. A child’s odds of having an ASD diagnosis increases if he/she has a sibling or parent with ASD, attention deficit hyperactivity disorder (ADHD), intellectual disability, schizophreniadepression, bipolar disorder or anxiety. Family medical history is an important factor for families considering a diagnostic evaluation.
  3. Co-occurring disorders (such as anxiety and depression) are more likely in individuals with ASD than the general population. Identifying emotion regulation issues in early childhood is thus essential.
  4. Neuroplasticity matters. Because ASD is a neurodevelopmental disorder, early treatment improves neuroplastic brain functioning and subsequent behavior. As a child develops, his/her brain becomes less plastic.
  5. Interventions geared at a child’s “first relationships” with their caregivers may exert a strong positive effect on the developmental trajectories of toddlers at high-risk of ASD and also have a positive impact on a child’s social skills with peers as they age.
  6. Research indicates that parent-child interactions in early childhood predict long-term gains in language skills into adulthood for individuals with diagnoses of ASD. Acquiring communicative, pragmatic and useful language by kindergarten has also been identified as a strong predictor of adaptive or functional “real life” skills, which are needed to navigate the environment in adolescence and adulthood.
  7. Social skills instruction in a child’s early years increases competency with peers in school. This social competency is associated with greater adaptive independence in children with ASD.
  8. Working with a “diagnostic navigator” early in your child’s life improves outcomes. Research clearly indicates that social support is vital to relieve stress associated with caregiving for a child with ASD and that a positive parent–professional relationship is helpful in alleviating family stress.

If you suspect your child has or is at higher risk for ASD and you are looking for a “diagnostic navigator” for your child, consider an evaluation with NESCA.  While early diagnosis of ASD can make a positive impact on a child’s trajectory, obtaining the accurate diagnosis and recommendations for interventions at any age is critical.

About the Author:

Dr. Renée Marchant provides neuropsychological and psychological (projective) assessments for youth who present with a variety of complex, inter-related needs, with a particular emphasis on identifying co-occurring neurodevelopmental and psychiatric challenges. She specializes in the evaluation of developmental disabilities including autism spectrum disorder and social-emotional difficulties stemming from mood, anxiety, attachment and trauma-related diagnoses. She often assesses children who have “unique learning styles” that can underlie deficits in problem-solving, emotion regulation, social skills and self-esteem.

Dr. Marchant’s assessments prioritize the “whole picture,” particularly how systemic factors, such as culture, family life, school climate and broader systems impact diagnoses and treatment needs. She frequently observes children at school and participates in IEP meetings.

Dr. Marchant brings a wealth of clinical experience to her evaluations. In addition to her expertise in assessment, she has extensive experience providing evidence-based therapy to children in individual (TF-CBT, insight-oriented), group (DBT) and family (solution-focused, structural) modalities. Her school, home and treatment recommendations integrate practice-informed interventions that are tailored to the child’s unique needs.

Dr. Marchant received her B.A. from Boston College with a major in Clinical Psychology and her Psy.D. from William James College in Massachusetts. She completed her internship at the University of Utah’s Neuropsychiatric Institute and her postdoctoral fellowship at Cambridge Health Alliance, a Harvard Medical School teaching hospital, where she deepened her expertise in providing therapy and conducting assessments for children with neurodevelopmental disorders as well as youth who present with high-risk behaviors (e.g. psychosis, self-injury, aggression, suicidal ideation).

Dr. Marchant provides workshops and consultations to parents, school personnel and treatment professionals on ways to cultivate resilience and self-efficacy in the face of adversity, trauma, interpersonal violence and bullying. She is an expert on the interpretation of the Rorschach Inkblot Test and provides teaching and supervision on the usefulness of projective/performance-based measures in assessment. Dr. Marchant is also a member of the American Family Therapy Academy (AFTA) and continues to conduct research on the effectiveness of family therapy for high-risk, hospitalized patients.
