# # # **Autism: Definition and Characteristics**
**Autism**, officially known as **Autism Spectrum Disorder (ASD)**, is a **neurodevelopmental condition** that affects how a person perceives the world and interacts with others. It is called a **"spectrum"** because it varies widely in type and severity from person to person.
---*Definition**
Autism Spectrum Disorder is characterized by:
1. **Persistent differences in social communication and interaction** across various contexts.
2. **Restricted and repetitive patterns of behavior, interests, or activities**.
These signs typically appear in early childhood, although they may not be diagnosed until later in life—especially in individuals who mask their traits well or in females (who are often underdiagnosed).

# # # 🧠 **Additional Notes**
* Autism is **not an illness or disease**—it’s a different way of experiencing the world.
* Intelligence and language ability vary widely. Some autistic people have **intellectual disabilities**, others are **gifted**, and many are somewhere in between.
* **Co-occurring conditions** are common, including **ADHD, anxiety, sensory processing disorder, and epilepsy**.
--Prevalence**
* Estimated to affect about **1 in 36 children** in the U.S. (CDC, 2023)
* More commonly diagnosed in boys, but this is changing as awareness grows
