Autism spectrum disorder is a lifelong neurodevelopmental difference in social communication and in patterns of behavior, interests and sensory processing. Diagnosis in teens and adults is based on a structured clinical assessment and developmental history. There is no medication for autism itself; psychiatric care focuses on co-occurring anxiety, depression, ADHD and irritability, with therapy, accommodations and support. Stedfast Psychiatry treats autism spectrum disorder at 25 Clarks Summit Drive in Bluffton and by video across South Carolina; new patients call (561) 234-4547.

- Taking language literally or difficulty with sarcasm and implied meaning
How we diagnose it
Diagnosing autism in a teenager or adult requires a careful clinical assessment. We take a developmental history going back to early childhood, with input from a parent or someone who knew you as a child when possible, and a detailed account of current social communication, routines, interests, sensory experiences and masking. We use standardized tools including the Autism Spectrum Quotient (AQ) and the RAADS-R for adults, and when a formal observational measure is needed we use or refer for the ADOS-2. We screen for ADHD, anxiety, depression, OCD, social anxiety and trauma, which both co-occur with autism and can be confused with it, and we distinguish autism from social anxiety disorder, schizoid traits and personality disorders. For adults seeking workplace or academic accommodations, or for complex presentations, we coordinate with neuropsychologists for comprehensive testing.

An estimated 2.2 percent of US adults, about 5.4 million people, are autistic, and most adults were never formally diagnosed.

Anxiety disorders affect roughly 40 percent of autistic adults, and depression affects 20 to 40 percent, far above general population rates.

Autism is diagnosed about 3 to 4 times more often in boys than girls, and girls and women are diagnosed later on average, partly because of masking.

Treatment for autism spectrum disorder in Bluffton
Medication management
No medication treats autism itself, and we do not prescribe to make someone less autistic. Medication targets co-occurring conditions and specific symptoms. SSRIs such as sertraline or escitalopram treat the anxiety and depression that affect the majority of autistic adults, started at low doses because sensitivity to side effects is common. Stimulants or non-stimulants (atomoxetine, guanfacine) treat co-occurring ADHD, which affects 30 to 50 percent of autistic people, with guanfacine also helping irritability and sleep. Risperidone and aripiprazole are FDA-approved for irritability associated with autism in children and adolescents and are used cautiously with metabolic monitoring when severe irritability or self-injury is present. Melatonin helps the sleep-onset problems that are nearly universal in autism. We avoid unnecessary polypharmacy and review every medication regularly.
Psychotherapy and support
Cognitive behavioral therapy adapted for autism, with concrete language, visual supports and attention to sensory factors, is effective for anxiety and depression in autistic teens and adults. Therapy also helps with understanding the diagnosis, reducing the cost of masking, building self-advocacy, managing burnout and navigating relationships and employment. Social skills groups benefit some teens. Occupational therapy addresses sensory needs. We connect patients with autism-affirming therapists, vocational rehabilitation services, support groups and, for students, disability services offices for accommodations under Section 504, an IEP or the ADA.
What to expect
The diagnostic evaluation is typically 90 minutes, sometimes across two visits, in person or by video, and we will ask you to complete questionnaires beforehand and, if possible, to have a parent or long-time partner share observations. You receive a written summary of the diagnosis, suitable for accommodation requests. For ongoing care, follow-ups are every one to three months depending on medication needs. Telehealth is available across Florida and South Carolina and many autistic patients prefer it, since it removes travel, waiting rooms and sensory load.

Frequently asked questions
Who provides autism spectrum disorder treatment at the Bluffton office?
The Bluffton team includes psychiatrist Dr. Josh Walters and physician assistant Amanda Skipworth. Every provider works under psychiatrist oversight and the same evaluation standard: about an hour for a first visit, validated screening scales, and a written plan.
Can I be seen by video instead of coming to Bluffton?
Yes. Stedfast Psychiatry providers are licensed in South Carolina and offer video visits for evaluations and follow-ups. Some situations, including certain controlled-substance prescriptions and first visits for young children, require an in-person appointment at 25 Clarks Summit Drive.
Does the Bluffton office take my insurance?
We accept most major commercial plans and Medicare. Call (561) 234-4547 with your member ID and we will verify benefits before the visit. Self-pay new-patient evaluations are $185.
How soon can a new patient be seen in Bluffton?
Most new patients are scheduled within one to two weeks. If you need to be seen sooner, ask about a video visit; those often open up within days. If you are in crisis, call or text 988 or go to the nearest emergency room rather than waiting.
Can I get Deep TMS or Spravato as a Bluffton patient?
Yes. Stedfast Psychiatry is licensed for both. Your Bluffton provider does the evaluation and the prior authorization; treatment sessions are scheduled at our Palm Beach Gardens TMS center and the Palm Beach Gardens Spravato rooms.
Can adults be diagnosed with autism?
Yes. Many adults, especially women and people who learned to mask, were never evaluated as children, and a diagnosis in adulthood is common and valid. The evaluation uses your developmental history, current experiences, standardized questionnaires and clinical observation. Adults seek diagnosis for self-understanding, to explain why anxiety or depression treatment has not fully worked, to access workplace or academic accommodations, or after a child's diagnosis. We provide written documentation.
Is there medication for autism?
No medication treats autism itself, and we would not want one that did. Medication treats the conditions that often come with autism and cause real distress: SSRIs for anxiety and depression, stimulants or non-stimulants for ADHD, melatonin for sleep, and in some cases low-dose aripiprazole or risperidone for severe irritability. We start low, go slow, and avoid stacking medications, because autistic people are often sensitive to side effects.
