What Is Autism? Causes, Types of Autism and Symptoms



What Is Autism?

Autism  is a developmental disorder that impairs the ability to communicate and interact. It is a complex neurobehavioral condition that includes having impairments in social interaction, develop language and communication skills combined with rigid and repetitive behaviors. Because of the wide range of symptoms, this condition is called autism spectrum disorder (ASD) nowadays. Children with autism have trouble with communication. It makes it very hard for them to express themselves either through words or with gestures, facial expressions, and touch. A child with ASD is highly sensitive may be greatly troubled by sounds, touches, smells, or sights that might seem normal to others.

Children who are autistic may also have repetitive, stereotyped body movements like rocking, pacing, or hand flapping. They may have unusual responses to people’s, attachments to objects, resistance to change in routines, or aggressive or self-injurious behavior. Some children may also develop seizures. And in a few cases, those seizures may not appear until adolescence.

What are the causes?

There is no confirmed single cause for ASD, but it is generally accepted that causes include abnormalities that may be there brain structure or function. Brain scans show differences in the shape and also a structure of the brain in children having autism compared to that in neurotypical children.

In many families, there appears to be a pattern of autism or other related disabilities, thus supporting the theory that this disorder may have a genetic basis. While no single gene has been discovered as causing autism, researchers continue to search for irregular segments of genetic code that children having autism may have inherited. It even appears that some children are born with a susceptibility to having autism, but researchers have not yet identified any “trigger” that causes autism to develop.

Types of ASD

There are three different types of ASD:

  • Autistic Disorder

People with an autistic disorder usually tend to have significant delays in language, social and communication challenges, and also unusual behaviors and interests. Many people with autistic disorder, also might have the intellectual disability.

  • Asperger Syndrome

People with this syndrome usually have some of the milder symptoms of autistic disorder.  They might also have social challenges and unusual behaviors and interests. However, they typically tend to not have problems with language or intellectual disability.

  • Pervasive Developmental Disorder

People who meet some of the criteria for autistic disorder or Asperger syndrome, but not all of them, may be diagnosed with PDD-NOS. People with PDD-NOS usually have fewer and milder symptoms than those with autistic disorder.  The symptoms might result in only social and communication challenges.
