Autism Symptoms Checklist

Download a FREE PRINTABLE autism symptoms checklist or diagnostic list for aspergers to help identify early signs in toddlers or older children as soon as possible. Suspecting that your child may have an autistic disorder is never fun, but the sooner you determine what's going on with your child the better their chances are of gaining necessary life skills.

Early intervention that involves applied behavior analysis with an ABA therapist, who has gone through training, greatly increases the chances of recovery from symptoms. It's not worth denying there may be a problem with your child. This will not make the warning signs you are seeing go away, in fact, they will likely only get worse.

Additional treatments for autistic disorder available are also important to start as soon as possible, such as biomedical treatments or occupational therapy for children that also appear to have issues with sensory processing

The autism symptom checklists are not intended to diagnose your child. They should be able to provide you with a good starting point for determining whether your child needs further evaluation, at which time you would want to take the form to your doctor.

The first checklist gives a list of the characteristics for autism as indicated by the DSM-IV diagnostic criteria. The second is an autism symptoms checklist for toddlers that is great for parents to use.

You may also find the following chart related to asperger syndrome behavior to be helpful for an older child that is communicating fairly well. This is similar to the first autism symptoms checklist that is provided and has been taken from the DSM-IV. However, it does appear that this diagnosis will be changing with the coming of the DSM-V and may have different terminology.
