Understanding, Support, and Hope for Every Step of the Journey
Every child grows and develops at their own pace. But when a child’s social interactions, communication, or behaviors follow a different path, it’s natural for parents to have questions. One possible explanation could be Autism Spectrum Disorder (ASD).
At St. Mary’s Health Care System, we believe that awareness, early diagnosis, and compassionate support can make a life-changing difference for children and their families.
What Is Autism Spectrum Disorder?
Autism Spectrum Disorder is a developmental condition that affects how a person communicates, interacts socially, and processes sensory input. The word “spectrum” is key-it reflects the wide range of strengths, challenges, and abilities each individual with autism may have.
Autism is not an illness or something to be “cured.” It’s a neurodevelopmental difference, and with the right support, children and adults with autism can lead fulfilling, joyful lives.
Common Signs of Autism in Children
Signs of ASD can appear as early as 18 months, though they may become more noticeable between the ages of 2 and 3. These signs vary widely but often include:
Social and Communication Differences:
- Limited eye contact
- Delayed speech or language development
- Repeating words or phrases (echolalia)
- Difficulty understanding nonverbal cues or social norms
- Preferring to play alone or not responding to their name
Behavioral and Sensory Signs:
- Repetitive movements (hand-flapping, rocking, spinning)
- Intense focus on certain topics or objects
- Sensory sensitivities (to light, sound, textures, or smells)
- Difficulty adapting to changes in routine
It’s important to remember that not all children with these traits have autism, and not all children with autism show every sign. If you notice any of these patterns, it’s a good idea to talk with your child’s healthcare provider.
How Is Autism Diagnosed?
Diagnosing autism usually involves a multi-step process, including:
- Developmental Screenings
During well-child visits, your pediatrician may use tools to monitor developmental milestones and identify early red flags. - Comprehensive Evaluation
If concerns arise, your provider may refer you to a specialist (such as a developmental pediatrician, neurologist, or child psychologist) for a full assessment. This often includes behavioral observations, parent interviews, and standardized testing. - Team Approach
A diagnosis may involve input from multiple professionals, including speech-language pathologists, occupational therapists, and educational specialists.
The earlier a diagnosis is made, the earlier support services can begin.
Why Early Intervention Matters
Early support is one of the most powerful tools for children with autism. It can help build essential life skills and improve long-term outcomes in communication, learning, and independence.
Some benefits of early intervention include:
✅ Improved language and social skills
✅ Increased school readiness and academic progress
✅ Better emotional regulation and reduced frustration
✅ Stronger family coping and support systems
Therapies might include speech therapy, occupational therapy, behavioral therapy (such as ABA), social skills training, and parent coaching. Each plan is tailored to the child’s unique strengths and needs.
Supporting Families, Together
Autism affects the entire family, not just the individual. That’s why compassionate, whole-family care matters.
