Genetic Variation
Heritability is estimated at 70 to 90 percent, with many common and rare gene variants influencing brain development and connectivity.

Understanding, Affirming and Supporting You
Recognizing the Signs
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by persistent differences in social communication and social interaction, alongside restricted or repetitive patterns of behavior, interests or activities. According to the CDC ADDM Network, approximately 1 in 31 children in the United States is identified as autistic, and a growing number of adults are receiving an autism diagnosis later in life.
You may experience the world in ways that feel different from those around you. That might look like deep focus on specific interests, sensitivity to sounds, lights or textures, a preference for routine and predictability, or finding social conventions tiring or confusing. Many autistic people also describe genuine strengths: pattern recognition, attention to detail, honesty and a capacity for sustained focus on what matters to them.
Autism is a difference in how the brain develops and processes information, not a disease to be cured. At Gonzales-Vigilar Psychiatric Services, our role is to support evaluation, help identify and manage co-occurring conditions (such as anxiety, ADHD, depression, OCD or sleep difficulties), and partner with you or your family in a way that affirms who you are.
Understanding the Root Causes
Autism is strongly biological. Twin and family studies estimate heritability at roughly 70 to 90 percent, meaning genetic factors play a central role. There is no single autism gene; instead, many common and rare gene variants influence how the developing brain organizes networks involved in social cognition, sensory processing, language and executive function. According to the National Institute of Mental Health, structural and functional differences in brain connectivity are present from early development.
Prenatal and perinatal factors, including advanced parental age, certain medication exposures during pregnancy and complications around birth, can modestly raise likelihood, but they do not cause autism on their own. Vaccines do not cause autism; this has been studied extensively and consistently disproven. Parenting style, attachment and screen time do not cause autism either.
What a comprehensive evaluation can clarify is the full picture: developmental history, current functioning, sensory profile, language and learning, and the presence of co-occurring conditions. From there, our Psychiatric Evaluation and, when indicated, Medication Management focus on the specific symptoms that are getting in the way of daily life, not on changing who you are.
How Presentation Changes from Childhood to Adulthood
In young children, autism often shows up as delayed or atypical language, limited shared attention, repetitive movements, intense focus on specific topics or objects, and strong reactions to changes in routine. Diagnosis at this age is usually a multidisciplinary process involving developmental pediatrics, speech-language pathology, occupational therapy and psychiatry. Dr. Gonzales-Vigilar is board-certified in child, adolescent and adult psychiatry, which is uncommon in Northern Virginia, and her training is particularly well suited to families navigating early questions about development.
In school-age children and teens, autism may look like social fatigue, anxiety in unstructured settings, difficulty with transitions or unspoken social rules, sensory overwhelm at school, or burnout after a day of "masking" to fit in. Co-occurring anxiety, ADHD and depression frequently emerge in these years and can become the reason a family first seeks psychiatric care.
In adults, late-identified autism is increasingly common, especially in women and in people who learned to mask early. You may have spent years being treated for anxiety, depression or burnout without anyone asking whether autism could be part of the picture. A thoughtful Psychiatric Evaluation can help clarify the diagnosis, validate your experience, and shape a plan focused on what would actually help.

Recognizing When to Seek Support
About Autism Spectrum Disorder
In young children, diagnosis is usually multidisciplinary, involving developmental pediatrics, speech and occupational therapy and psychiatry. In adults, a careful psychiatric evaluation with developmental history and current functioning is often central, sometimes alongside psychological testing.
Roughly 70 percent of autistic people have at least one co-occurring mental health condition. ADHD, anxiety, depression, OCD, sleep disorders and irritability are among the most common, and they are often where psychiatric care makes the biggest difference.
We do not provide ABA, and we recognize that views on ABA vary widely within the autistic community. We coordinate with behavioral, developmental and educational specialists in the area and respect each family's informed choices about therapy.
Genomind does not diagnose autism, but it can be very useful when medication is part of the plan. Medication sensitivity is common in autistic clients, and pharmacogenomic results help guide safer, better-tolerated choices for co-occurring anxiety, ADHD or depression.
Medication does not change core autistic traits, but it can help with sleep problems, severe anxiety, irritability or attention difficulties that worsen sensory overwhelm. We discuss benefits, risks and alternatives carefully before starting anything.
We accept several major insurance plans. For the most current list, please call 571-291-2449 or message us through the Valant patient portal, and we will confirm coverage and out-of-pocket expectations for your evaluation.
