Autism is a complex disorder that affects the neurobiological system. Although it is typically called a developmental disorder because it can cause delays in some developmental milestones, it can have lifelong effects. Autism typically affects social behavior, language and certain behaviors involving routines and order. Autism is typically diagnosed in childhood or infancy. Early diagnosis and treatment can greatly reduce the effects of autism on a person.
Step 1
Look for certain "red flag" behaviors. Although many of the characteristic behaviors of autism can be difficult to identify in infants younger then 18 months, some of the symptoms of autism can be identified in children as young as eight months of age. These include poor social attention (not responding to one's name), not smiling when being smiled at, hypotonia (limp muscles), unstable attention (easily distracted) and poor eye contact. Other signs may include being more attached to "hard" toys, such as a flashlight, than "soft" ones, like a blanket. Other red flags include the infant appearing to tune out the outside world and slowly developing language skills. Autistic infants may also not wave goodbye.
Step 2
Talk to your pediatrician. This is a critical step, because autism is a complex disease and may be difficult to diagnose. Your pediatrician will listen to your concerns and may ask you questions, have you fill out a questionnaire or ask to observe your infant's behavior.
Step 3
See a developmental specialist. These medical specialists are trained in diagnosing developmental disorders such as autism and their insight and expertise is essential in determining if your infant does have autism. The specialist may wish to make and review videotapes of your infant's behavior and personally observe your infant. This doctor will also be able to advise you as to how best to treat your child's problems.
