What is Autism spectrum disorder( ASD)?
Autism spectrum disorder (ASD), or autism, is a broad term used to describe a group of neurodevelopmental conditions.
These conditions are characterized by differences in communication and social interaction. People with ASD often demonstrate restricted and repetitive interests or patterns of behavior.
ASD is found in people around the world, regardless of race and ethnicity, culture, or economic background.
There are indications that instances of autism are on the rise. Some attribute this increase to environmental factors. However, experts debate whether there’s an actual increase in cases or just more frequent diagnoses.
Types of Autism
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is published by the American Psychiatric Association (APA). Clinicians use it to diagnose a variety of psychiatric disorders.
The most recent fifth edition of the DSM was released in 2013. The DSM-5 currently recognizes five different ASD subtypes, or specifiers. They are:
- with or without accompanying intellectual impairment
- with or without accompanying language impairment
- associated with a known medical or genetic condition or environmental factor
- associated with another neurodevelopmental, mental, or behavioral disorder
- with catatonia
Someone can receive a diagnosis of one or more specifiers.
Before the DSM-5, autistic people may have received a diagnosis of:
- autistic disorder
- Asperger’s syndrome
- pervasive development disorder-not otherwise specified (PDD-NOS)
- childhood disintegrative disorder
Symptoms of Autism

Symptoms of ASD typically become clearly evident during early childhood, between ages 12 and 24 months. However, symptoms may also appear earlier or later.
Early symptoms may include a marked delay in language or social development.
The DSM-5 divides symptoms of ASD into two categories:
- problems with communication and social interaction
- restricted or repetitive patterns of behavior or activities
To be diagnosed with autism, a person must experience symptoms in both of these categories.
Treating ASD
For some autistic people, supportive therapies and other considerations can help them feel better or alleviate certain symptoms.
Many approaches involve therapies such as:
- behavioral therapy
- play therapy
- occupational therapy
- physical therapy
- speech therapy
Massages, weighted clothing and blankets, and meditation techniques may also help some autistic people manage symptoms. However, results will vary. Some people may respond well to certain approaches, while others may not.
