Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects communication and behavior. It is called a "spectrum" disorder because people with ASD can have a range of symptoms and varying levels of impairment. Symptoms of ASD typically appear in early childhood, often before the age of three.

Symptoms of ASD can range from mild to severe and can affect individuals in different ways. Some people with ASD may have only mild challenges, while others may have more severe impairments that require more intensive support. Some common symptoms of ASD include:

Difficulties with social interactions and communication: People with ASD may have trouble interpreting social cues and may have difficulty initiating or maintaining conversations. They may also have difficulty understanding other people's emotions and may not respond to social cues like smiling or making eye contact.
Repetitive behaviors or routines: People with ASD may engage in repetitive behaviors or routines, such as repeating certain phrases or engaging in the same activities over and over again. They may also become upset if their routines are disrupted.
Struggles with sensory processing: Some people with ASD may be sensitive to certain sensory stimuli, such as loud noises or bright lights. They may also have difficulty interpreting sensory information, such as pain or temperature.
Limited interests or unusual preoccupations: People with ASD may have limited interests or may be preoccupied with a particular topic or activity. They may also be more interested in objects than in people.
It is important to note that not everyone with ASD will have all of these symptoms, and the severity of symptoms can vary greatly from person to person. If you have concerns about your child's development, it is important to talk to your pediatrician. They can evaluate your child and refer you to appropriate specialists if necessary. Early intervention is key to improving outcomes for individuals with ASD.
