Autism

What Is Autism?There is no one type of autism, but many.

Autism, or autism spectrum disorder (ASD), refers to a broad range of conditions characterized by challenges withsocial skills, repetitive behaviors, speech and nonverbal communication. According to the Centers for Disease Control, autism affects an estimated 1 in 59 children in the United States today.

We know that there is not one autism but many subtypes, most influenced by a combination of genetic and environmental factors. Because autism is a spectrum disorder, each person with autism has a distinct set of strengths and challenges. The ways in which people with autism learn, think and problem-solve can range from highly skilled to severely challenged. Some people with ASD may require significant support in their daily lives, while others may need less support and, in some cases, live entirely independently.

Several factors may influence the development of autism, and it is often accompanied by sensory sensitivities and medical issues such as gastrointestinal (GI) disorders, seizures or sleep disorders, as well as mental health challenges such as anxiety, depression and attention issues.

Indicators of autism usually appear by age 2 or 3. Some associated development delays can appear even earlier, and often, it can be diagnosed as early as 18 months. Research shows that early intervention leads to positive outcomes later in life for people with autism.

* In 2013, the American Psychiatric Association merged four distinct autism diagnoses into one umbrella diagnosis of autism spectrum disorder (ASD). They included autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome.

One of the most important things you can do as a parent or caregiver is to learn the early signs of autism and become familiar with the typical developmental milestones that your child should be reaching.

What are the signs of autism?

The timing and severity of autism’s early signs vary widely. Some infants show hints in their first months. In others, symptoms become obvious as late as age 2 or 3.

Not all children with autism show all the signs. Many children who don’t have autism show a few. That’s why professional evaluation is crucial.

The following “red flags” may indicate your child is at risk for an autism spectrum disorder. If your child exhibits any of the following, please don’t delay in asking your pediatrician or family doctor for an evaluation:

By 6 months

  • Few or no big smiles or other warm, joyful and engaging expressions.
  • Limited or no eye contact.

By 9 months

  • Little or no back-and-forth sharing of sounds, smiles or other facial expressions

By 12 months

  • Little or no babbling
  • Little or no back-and-forth gestures such as pointing, showing, reaching or waving
  • Little or no response to name.

By 16 months

  • Very few or no words.

By 24 months

  • Very few or no meaningful, two-word phrases (not including imitating or repeating)

At any age

  • Loss of previously acquired speech, babbling or social skills
  • Avoidance of eye contact
  • Persistent preference for solitude
  • Difficulty understanding other people’s feelings
  • Delayed language development
  • Persistent repetition of words or phrases (echolalia)
  • Resistance to minor changes in routine or surroundings
  • Restricted interests
  • Repetitive behaviors (flapping, rocking, spinning, etc.)
  • Unusual and intense reactions to sounds, smells, tastes, textures, lights and/or colors
