Autism Spectrum Disorders Overview
Autism spectrum disorders (ASDs) continue to be an important public health concern. ASDs are a group of developmental disabilities that can cause significant social, communication and behavioral challenges. The Minnesota Department of Health is committed to continuing to provide essential data on ASDs and develop resources that help identify children with ASDs as early as possible.
What are autism spectrum disorders?
Autism spectrum disorders (ASD) are a developmental disability, something that occurs in the early formation of the brain. There is usually nothing about how a person with ASD looks that sets them apart from other people, but they may communicate, interact, behave, and learn in ways that are different from most people.
It is estimated that 1 in 88 children have been identified with an ASD. Boys are 5 times more likely to be affected than girls. ASDs occur in all racial, ethnic and socioeconomic groups. ASD affects each individual in a different way – with varying degrees of severity – thus it is a "spectrum disorder".
Causes of ASD
Causes of ASDs are not known. However, there are likely many causes for multiple types of ASDs. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.
Importance of early diagnosis
Autism spectrum disorders are treatable. Children do not "outgrow" ASD, but studies show that early diagnosis and intervention lead to significantly improved outcomes. It is important to learn the signs and act early. The earlier you get help, the better for your child.

Next Steps: Diagnosis
A medical diagnosis will more specifically determine a child’s disabilities and therefore his or her need for and access to services, as well as ensure that the child’s primary and other health care needs are addressed. A medical evaluation may be necessary to receive services through medical insurance or to access other funding resources such as, but not limited to: Medical Assistance (MA/TEFRA), Supplemental Security Income (SSI), or county case management. A medical diagnosis is most often assigned by a psychologist or physician who specializes in children with developmental differences.
A school evaluation is required to determine eligibility for school district special education and related services. The evaluation is completed by a team of professionals and helps to identify a child’s strengths, learning style, and areas of need. If a child meets criteria for school district services, the educational team will meet with parents to develop an educational plan for the child.
Either a medical diagnosis or school evaluation may lead to recommendations for a broad range of interventions; for example referrals to medical specialists, neurologists, private rehabilitation services, county social services, financial support, family support and family guidance or therapy.
It is important to learn the signs and act early. The earlier you get help, the better for your child.
There is no cure for autism, however, therapy and behavioral help can greatly improve your child’s opportunities to do well in life.
A health care home, also known as a medical home, is an approach to health care in which primary care providers, families and patients work in partnership to improve health outcomes and quality of life. A team of health professionals work together with patients and families to provide the best care. A care coordinator will make sure that all providers, including specialists, share needed information about patients’ health through patient tracking and care plans. Comprehensive care includes preventive, acute and chronic care. Care coordinators help patients manage their care.
