Clinical Information

Autism Spectrum Disorder, or ASD for short, is a neurodevelopmental disorder. This disorder impacts a person’s sensory processing, behavior, and capability to communicate with others.

It’s a complex disorder with no designated medical tests, so specialists who diagnose it will conduct interviews and multiple assessments to get enough information about a person and cross-check it with The Diagnostic and Statistical Manual of Mental Disorders.

Based on research, Autism Spectrum Disorder develops early, and its symptoms tend to manifest between ages 1 to 3. Given this, it’s always best to check children for ASD as soon as possible so that their ASD symptoms can be managed early. That way, it becomes possible for the child to grow up without their ASD hindering their daily lives.

Synonyms Include:

Active infantile autism
Autism spectrum disorder, epilepsy, arthrogryposis syndrome
Autistic disorder of childhood onset
High-functioning autism
Residual infantile autism
Autism and facial port-wine stain syndrome
Autism epilepsy syndrome due to branched-chain ketoacid dehydrogenase kinase deficiency

Commonly asked questions

Healthcare professionals who specialize in assessing, diagnosing, and treating ASD will look at the following: if the person has trouble communicating with others and if they can understand non-verbal communication, if they have difficulty establishing relationships, if they have problem with language, if there is an intense obsession for their interests whether “normal” or “unusual,” if they react strangely or have an aversion to certain noises and other sensory stimuli if they don’t take change well, and if they have repetitive behaviors.

They should tell parents to monitor their children for the following:

If they don’t look at the parents when called by name
If they don’t make any joyful expressions by the age of 6 months
If they don’t smile, make sounds, or make faces by the period of 9 months
If they don’t babble by the time they are one year old
If they don’t know how to make gestures like waving by the time they are one year old
If they don’t say any words when they’re already 16 months old
If they can’t know phrases by the time they are two years old

This means that the person has a mild form of Autism Spectrum Disorder. High-functioning autistics can speak, read, write, and perform tasks without support.
