ASD is defined by a certain set of behaviors that can range from the very mild to the severe.
The following possible indicators of ASD were identified on the Public Health Training Network Webcast, Autism Among Us.
Some moms and dads report the change as being sudden, and that their kids start to reject individuals, act strangely, and lose language and social skills they had previously acquired.
In other cases, there is a plateau, or leveling, of progress so that the difference between the youngster with autism and other kids the same age becomes more noticeable.
Each youngster will display communication, social, and behavioral patterns that are individual but fit into the overall diagnosis of ASD.
Kids with ASD do not follow the typical patterns of child development.
If a youngster has symptoms of either of these disorders, but does not meet the specific criteria for either, the diagnosis is called pervasive developmental disorder not otherwise specified (PDD-NOS).
Other rare, very severe disorders that are included in the ASD are Rett syndrome and childhood disintegrative disorder.
After a period of normal development, sometime between 6 and 18 months, autism-like symptoms begin to appear.
The first signs of an Autism Spectrum Disorder (ASD) can also appear in kids who seem to have been developing normally.
When an engaging, babbling toddler suddenly becomes silent, withdrawn, self-abusive, or indifferent to social overtures, something is wrong.
An estimate based on four surveys of ASD found fewer than two kids per 100,000 with ASD could be classified as having CDD. Until this time, the youngster has age-appropriate skills in communication and social relationships.
The long period of normal development before regression helps differentiate CDD from Rett syndrome.
