Characteristics Of autism

Autism: A Spectrum Disorder With Varied Individual Characteristics

Autism, as defined by the Autism Society of America, is a complex and lifelong developmental disability that appears early in childhood and affects the individual’s social and communication skills, self-regulatory behaviors, and relationships. The characteristics of autism and the intensity of symptoms can vary depending on the individual. Therefore, autism is referred to as a “spectrum disorder.” The first signs of autism generally emerge between 24 and 36 months of age, and there is no single-known cause of the disability.

Signs of Autism

Autism and autism spectrum disorder (ASD) are general terms used for grouping complex disorders affecting brain development. These developmental disorders are characterized in degrees by the severity of the below indicators:

  • Social interaction difficulties
  • Nonverbal and verbal communication difficulties
  • Repetitive behaviors

Developmental disabilities characterized by these disabilities include:

  • Rett syndrome
  • Autistic disorder
  • Pervasive developmental disorder-not otherwise specified (PDD-NOS)
  • Childhood disintegrative disorder
  • Asperger syndrome

ASD can be associated with the following:

  • Difficulties in motor coordination
  • Intellectual disability
  • Difficulties in attention
  • Physical health issues such as GI disturbances and sleep
  • Some individuals with ASD excel in particular skills or areas — such as art, math or music

Early Signs of Autism

Early symptoms of autism in babies or toddlers often go unrecognized by parents or caregivers. One of the most important things you can do for your child after birth is to learn the early signs of autism. Recognizing the  first signs of autism can lead to an earlier diagnosis and early intervention for children with autism. Research suggests that early intervention leads to the best outcomes for children with autism and a better quality of life. Get familiar with typical developmental milestones your child should be reaching as he or she grows. Use the list below to understand if your child may be showing the first signs of autism.

  • Offers no warm or joyful expressions by 6 months old or after
  • Doesn’t exchange smiles, sounds and other facial expressions with others by 9 months
  • Is not babbling by 12 months
  • Doesn’t use nonverbal gestures for showing, pointing, waving or reaching by 12 months
  • Speaks no words by 16 months
  • Doesn’t form meaningful, two-word phrases by 24 months (not including repeating or imitating)
  • Loses babbling, speech or social skills at any age

Characteristics of Autism Spectrum Disorder

The core signs  of autism in children are social communication challenges and repetitive or restrictive behaviors. While young children may display these characteristics  on occasion, a child with autism will consistently display these charactersitics and they may interfere with his or her daily life. Health care professionals make an autism diagnosis by assessing behaviorsassociated with social communication challenges and repetitive or restrictive behaviors.
