Diagnostic Overshadowing

Diagnostic overshadowing in Autism occurs when the symptoms and behaviors associated with autism obscure or overshadow the presence of other mental or physical health conditions. This can lead to misdiagnosis, underdiagnosis, or delayed diagnosis of other conditions, ultimately impacting the individual's overall care and treatment outcomes.

Key Points

  1. Misattribution of Symptoms: Symptoms that might indicate another disorder are often interpreted as part of the autism, leading to misattribution. For example, anxiety, depression, or gastrointestinal issues might be seen merely as behaviors or characteristics of autism.

  2. Challenges in Communication: Communication challenges and Alexithymia faced by many autistics can make it harder for healthcare providers to identify additional conditions.

  3. Biases and Assumptions: Healthcare providers may have implicit biases or assumptions about autism that lead them to overlook other conditions. They might assume that all behavioral issues or health complaints are related to autism without considering other potential causes.

  4. Lack of Specialized Training: Not all healthcare providers are trained to recognize the complex interplay of autism and co-occurring conditions. This lack of specialized training can result in diagnostic overshadowing.

  5. Impact on Quality of Care: Diagnostic overshadowing can result in inadequate treatment plans. If other conditions are not recognized, the autistic might not receive appropriate interventions or therapies that address their full range of health needs.

Examples 

  • Mental Health: An autistic person might also have depression, but their low mood and social withdrawal may be seen as just part of their autism or obstinate or noncompliance, delaying the correct diagnosis and treatment of depression.

  • Physical Health: An autistic experiencing pain or discomfort due to a medical condition like GI  issues might have their symptoms attributed to behavioral issues, leading to inadequate medical evaluation and treatment.

Addressing Diagnostic Overshadowing:

  1. Comprehensive Assessments: Conducting thorough and holistic assessments that consider both autism and potential co-occurring conditions.
  2. Training for Providers: Educating healthcare providers about the risks of diagnostic overshadowing and training them to recognize and differentiate symptoms.
  3. Effective Communication: Developing better communication strategies to help autistics express their symptoms and concerns.
  4. Awareness and Advocacy: Raising awareness among caregivers, educators, and clinicians about the importance of looking beyond autism to identify other health issues.
