The Mississippi Department of Mental Health is proud to introduce the Division of Autism Services, established under House Bill 807 during the 2025 Regular Legislative Session. Housed within DMH’s Bureau of Intellectual and Developmental Disabilities, the division was created in response to the need for a statewide, coordinated system of care for individuals with Autism Spectrum Disorder and their families.
Our division is committed to connecting Mississippians with the services, tools and guidance they need to live full, self-directed lives in their communities. Whether you are newly navigating an autism diagnosis, seeking additional support, or looking for resources to better serve the individuals in your care, the Division of Autism Services is here to help every step of the way.
About Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects how a person communicates, learns and experiences the world around them. Because autism is a spectrum, no two individuals experience it the same way — strengths, challenges and support needs vary widely from person to person.
Autism is one of the most common developmental conditions in the United States. According to the Centers for Disease Control and Prevention (CDC), approximately 1 in 31 children in the U.S. has been identified with ASD. In Mississippi, thousands of individuals across all ages and backgrounds are living with autism.
ASD is typically identified in early childhood, though many individuals receive a diagnosis later in life. Common characteristics may include:
Differences in social communication and interaction
Repetitive behaviors or routines
Heightened or reduced sensitivity to sensory experiences
Highly focused interests or areas of expertise
Differences in learning style or information processing
It is important to recognize that autism is not a barrier to a meaningful and fulfilling life. With the right supports and opportunities, individuals with autism can and do thrive in their homes, schools, workplaces and communities.
Frequently Asked Questions
The Division of Autism Services is a dedicated division within the Mississippi Department of Mental Health’s Bureau of Intellectual and Developmental Disabilities. Established by the Mississippi Legislature in 2025, the division provides statewide leadership in program development for children and adults with ASD, including the establishment of program standards and coordination of program capacity across Mississippi.
The division is responsible for developing and coordinating a long-term, comprehensive statewide system of care for individuals with ASD — one grounded in scientific research and nationally recognized best practices. This includes working across agencies, engaging the public and sharing information openly to support better decisions and more effective care. Services are designed to meet individuals where they are…across every stage of life and in the most inclusive settings possible.
The Mississippi Department of Mental Health believes in a system of services that is person-centered and is built on the strengths of individuals and families while meeting their needs for special services. A variety of services is available from numerous providers in Mississippi, both those that are DMH Certified Providers and other appropriately-licensed and credentialed people and providers. Our goal is for services to be selected in collaboration with parents or guardians of children with ASD, as well as adults with ASD themselves, ensuring that individuals and families have a voice in their own care. We are happy to help you find the right support – just contact our division by emailing Shavvone Williams at shavvone.williams@dmh.ms.gov or call the DMH Helpline at 1-877-210-8513.
Autism is diagnosed through a comprehensive evaluation conducted by a qualified healthcare professional, such as a psychologist, developmental pediatrician or psychiatrist. ASD is defined according to the current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association. There is no single medical test for autism; instead, clinicians assess behavior, development and communication. If you are concerned about yourself or a loved one, speak with your primary care provider about a referral for evaluation.
No. While autism is often identified in early childhood, many individuals — particularly women, girls, and people of color — are diagnosed in adolescence or adulthood. The Division of Autism Services is committed to supporting individuals with ASD across their entire lifespan, recognizing that the need for services and support does not end in childhood. A later diagnosis can still be a meaningful and life-changing step toward accessing the right support.
Autism and intellectual disability are separate diagnoses, though some individuals may have both. Intellectual disability refers to significant limitations in intellectual functioning and adaptive behavior, while autism primarily involves differences in social communication and behavior. Each person’s profile of strengths and support needs is unique.
