Systemic Issues in Autistic Individuals: Management Strategies
Autistic individuals require coordinated multidisciplinary medical assessment and management of systemic comorbidities, with approximately 50% having intellectual disability, high rates of gastrointestinal and sensory problems, and frequent psychiatric comorbidities including anxiety, depression, and ADHD that must be actively identified and treated rather than overshadowed by the autism diagnosis. 1
Medical Assessment and Systemic Evaluation
All children with ASD require a comprehensive medical assessment including:
- Physical examination with specific attention to dysmorphic features 1
- Hearing screen to rule out auditory impairment 1
- Wood's lamp examination for tuberous sclerosis 1
- Genetic testing: chromosomal microarray (24% diagnostic yield), G-banded karyotype (2.5% yield), and fragile X testing (0.57% yield) 1
- Gastrointestinal symptom assessment, as GI problems are very common in this population 2
- Sensory problem evaluation 2
Cognitive and Intellectual Functioning
Intellectual disability occurs in approximately 85% of individuals with autistic disorder:
- 50% exhibit severe or profound intellectual disability 1
- 35% exhibit mild to moderate intellectual disability 1
- Only 20% have IQs in the normal range 1
Cognitive assessment must include:
- Formal IQ testing to establish intellectual disability as a separate diagnosis 1
- Adaptive functioning measures 3
- Assessment tools like VB-MAPP or ABLL-R to guide treatment targets 3
Psychiatric Comorbidities
Avoid diagnostic overshadowing—the tendency to miss comorbid conditions when autism is the prominent diagnosis. 1, 3
Common psychiatric comorbidities requiring active screening and treatment:
Mood and Anxiety Disorders
- Affective symptoms are frequently observed including lability, inappropriate affective responses, anxiety, and depression 1
- Overt clinical depression occurs particularly in adolescents with higher-functioning ASD (formerly Asperger's disorder) 1, 3
- Cognitive behavioral therapy has demonstrated efficacy for anxiety and anger management in high-functioning youth with ASD 1
Attention-Deficit/Hyperactivity Disorder
- Attentional difficulties are frequent, reflecting cognitive, language, and social problems 1, 3
- DSM-5 removed the historical prohibition on diagnosing ADHD in those with ASD 1
- Methylphenidate showed 49% response rate in a large randomized controlled trial for children with ASD and elevated hyperactivity scores 1
Behavioral Difficulties
- Range includes hyperactivity, obsessive-compulsive phenomena, self-injury, aggression, stereotypies, and tics 1
- Impairments in emotion regulation lead to under- and over-reactivity 1
- Bullying involvement (victimization and perpetration) occurs more frequently in general educational settings 1
Communication and Language Impairments
Communication deficits are core systemic features requiring specialized intervention:
- For nonverbal individuals, implement alternative communication modalities including Picture Exchange Communication System, sign language, activity schedules, and voice output communication aids 3
- Speech/language therapy is essential for those with significant language challenges 3
- High-functioning individuals with fluent speech often have severely impaired pragmatic language skills requiring explicit teaching 1, 3
Sensory and Motor Difficulties
Occupational and physical therapy evaluations are needed to address:
- Sensory processing abnormalities that are very common 2
- Motor difficulties that may impact functional abilities 3
- Note: Sensory-oriented interventions like auditory integration lack evidence of efficacy 1
Treatment Framework
Behavioral Interventions (First-Line)
Applied Behavioral Analysis (ABA) techniques are the primary approach for behavioral problems: 3
- Perform functional analysis of target behaviors to identify reinforcement patterns 3
- Early Intensive Behavioral Intervention based on ABA principles shows effectiveness for young children 3
- Use visual schedules, planners, timers, and assistive technology for organizational weaknesses 3
- Teach behavior chains using forward or backward chaining with reinforcement 3
Educational Approaches
Structured educational programs with explicit teaching are consensus recommendations: 1, 3
- Programs require planned, intensive, individualized intervention with experienced interdisciplinary teams and family involvement 1, 3
- Two models with demonstrated efficacy: Early Start Denver Model and TEACCH program 1, 3
- Educational plans must reflect accurate assessment of strengths and vulnerabilities with explicit goals and monitoring 1, 3
Pharmacotherapy
Reserve pharmacotherapy for specific target symptoms or comorbid conditions when behavioral approaches are insufficient: 3
- Target specific symptoms such as hyperactivity, aggression, or mood symptoms rather than core autism features 3
- Methylphenidate for ADHD symptoms in appropriate candidates 1
Multidisciplinary Coordination
Coordinate care across multiple disciplines throughout the lifespan: 1, 4
- Early: developmental assessment, diagnosis, genetic counseling 4
- Childhood: speech/language therapy, special education, parent training, neurologic assessment 4
- Adolescence/adulthood: behavior therapy, pharmacotherapy, occupational therapy, sexuality issues, transition training, housing options, guardianship 4
- Advocacy is relevant throughout the life span 4
System-Level Considerations
Address barriers to accessing comprehensive care:
- Multiyear waitlists for diagnostic services exist in many systems 5
- Insurance coverage gaps limit access to interventions 5
- Racism and systemic inequities persist in autism care across the United States 5
- System reorganization using access improvement principles can dramatically reduce delays (94% reduction in waitlists demonstrated) 6
