Parents often struggle to meet their newborn’s needs because they simply don’t know what they want when they are crying. Zoundream is not only translating cries, but planning to expand to be able to detect atypical developments in newborns. Veuer’s Johana Restrepo has more.

Autism is one of a group of serious developmental problems called autism spectrum disorder that appears in early childhood — usually before age 3. Though symptoms and severity vary, all autism spectrum disorders affect children’s ability to communicate and interact with others.

Children with autism generally have problems in three crucial areas of development: social interaction, language and behavior.

Catching autism spectrum disorder early can improve quality of life. By recognizing the early signs and symptoms, you can help children learn, grow and thrive.

Signs and symptoms

Some children show signs of autism spectrum disorder in early infancy, such as reduced eye contact, lack of response to their name or indifference to caregivers. Others develop normally for the first few months or years of life, but then they suddenly become withdrawn or aggressive, or they lose language skills they had already acquired. Signs usually are seen by age 2.

Communication and social skills

Children with autism spectrum disorder may have problems with communication skills and social interaction. Common signs include:

  • Fails to respond to their name or appears not to hear you at times.
  • Resists cuddling and holding and seems to prefer playing alone.
  • Has poor eye contact and lacks facial expression.
  • Doesn’t speak, has delayed speech or loses previous ability to say words or sentences.
  • Can’t start or maintain a conversation.
  • Speaks with an abnormal tone or rhythm and may use a singsong voice or robot-like speech.
  • Doesn’t appear to understand simple questions or directions.
  • Doesn’t express emotions or feelings and appears unaware of others’ feelings.
  • Doesn’t point at or bring objects to share interest.
  • Inappropriately approaches social interactions by being passive, aggressive or disruptive.
  • Has difficulty recognizing nonverbal cues, such as interpreting other people’s facial expressions, body postures or tone of voice.
  • Repeats words or phrases verbatim but doesn’t understand how to use them.

Behavior patterns

Children with autism spectrum disorder may have limited, repetitive patterns of behavior, interests or activities, including:

  • Performs repetitive movements, such as hand-flapping, rocking or spinning.
  • Performs activities that could self-harm, such as biting or head-banging.
  • Has problems with coordination or has odd movement patterns, and has odd, stiff or exaggerated body language.
  • Is fascinated by details of an object, such as the spinning wheels of a toy car, but doesn’t understand the overall purpose or function of the object.
  • Develops specific routines or rituals and becomes upset at the slightest change.
  • Is unusually sensitive to light, sound or touch but may be indifferent to pain or temperature.
  • Doesn’t take part in make-believe or cooperative play with other children.
  • Fixates on an object or activity with abnormal intensity or focus.
  • Only wants to eat a few specific foods or refuses foods with a certain texture.

Long-term factors

Children with autism spectrum disorder are likely to have a unique pattern of behavior and level of severity — from low-functioning to high-functioning.

Some children with the disorder have difficulty learning, and some have signs of lower-than-normal intelligence. Others may learn quickly but have trouble communicating and applying what they know in everyday life and adjusting to social situations.

Because children can have a unique mixture of symptoms, severity sometimes can be difficult to determine. Severity is generally based on the level of impairments and how they affect functionality.

Some children with the disorder become more engaged and show fewer disturbances in behavior as they mature. Others can continue to have language or social difficulties, and the teen years can bring more behavioral and emotional problems.

Treatment

Based on the signs and symptoms, if you believe your child may be showing signs of autism spectrum disorder, discuss it with their doctor, and ask about developmental testing.

While there is no cure for autism, intensive, early diagnosis and treatment can make a big difference in the lives of many children with the disorder.

The ultimate goal of treatment is to increase children’s ability to function, reduce symptoms and help children’s development and learning. Autism symptoms and severity differ greatly. Thus, treatment options for children diagnosed with autism also vary.

Typically, treatment options can include individualized behavioral interventions, speech and occupational therapy, medications and other therapies that include the whole family.
