The Neurologist's Perspective on Autism: Key Insights and FAQs

🔍Autism is a collection of conditions with shared clinical features, rather than a singular biological entity.

🧬There are different etiologies of autism, including polygenic and syndromic or monogenic causes.

🔑Clinical skills, such as identifying regression, encephalopathy, abnormal electrical activity, dysmorphic features, and functional system involvement, can enhance the diagnosis of genetic or brain anatomic causes of autism.

🩺Brain imaging, such as MRI, can help identify anatomic changes or focal cortical dysplasias that may contribute to autism and impact treatment decisions.

🔬Whole exome sequencing is a powerful tool that can identify de novo mutations in genes associated with autism and developmental disabilities, improving diagnostic accuracy.

Is autism a singular biological entity?

—No, autism is a collection of conditions with shared clinical features.

How can clinical skills help identify genetic or brain anatomic causes of autism?

—Clinical skills, such as identifying regression, encephalopathy, abnormal electrical activity, dysmorphic features, and functional system involvement, can help identify children who are more likely to have a single gene or other biochemical causes of autism.

What role does brain imaging play in the diagnosis of autism?

—Brain imaging, such as MRI, can help identify anatomic changes or focal cortical dysplasias that may contribute to autism and impact treatment decisions.

What is whole exome sequencing?

—Whole exome sequencing is a genetic testing technique that sequences most of the protein-coding genes in an individual's genome, allowing for the identification of de novo mutations associated with autism and developmental disabilities.

How can whole exome sequencing improve the diagnosis of autism?

—Whole exome sequencing can identify de novo mutations in genes associated with autism and developmental disabilities, providing a more accurate diagnosis and guiding personalized treatment plans.
