The term “spectrum” in autism spectrum disorder refers to the wide range of symptoms and severity.
Every child with autism is different. All will have challenges with communication and social skills, but not in the same way. Autism is a spectrum disorder because it can cause mild problems, severe problems, or
something in between.

Autism is a lifelong neuro-developmental condition, it means a developmental disability significantly
affecting verbal and nonverbal communication and social interaction, generally evident before age 2, which adversely affects a child’s educational performance.

Other characteristics often associated with autism are engagement in repetitive activities and stereotyped movements, resistance to environmental change or change in daily routines, and unusual responses to sensory experiences; (as defined by IDEA criterion, 2004)

Causes of Autism

Autism spectrum disorder has no single known cause. Given the complexity of the disorder and the fact that symptoms and severity vary, there are probably many causes.

Speech and language evaluation

A speech-language evaluation is the measurement of a person’s communication skills. It is done
to gain more understanding of a person’s communication skills and needs.
Comprehensive Speech and Language evaluation, which includes a combination of
standardized and informal assessments, which assess for following:

  • Expressive language (how a person uses language to communicate)
  • Receptive language (how a person understands language)
  • Social Engagement and Interaction (how a person plays, interacts and/or communicates with others)
  • Play behaviour
  • Phonemic Awareness (the ability to recognize and manipulate the spoken parts of words)
  • Hearing Screening (depending on their age and medical history)

Diagnostic tools for Autism

these problems have autism. Knowing which one your child has will help with the

functioning and quality of life. ASD affects each person differently, meaning that people
with ASD have unique strengths and challenges and different treatment
needs. Treatment plans usually involve multiple professionals and treatment
programmes are individualized.
