What kind of doctor treats Asperger's Syndrome?
A developmental pediatrician or a child psychologist often sees children first. A psychiatrist or psychologist can care for adults. A primary care doctor can start the evaluation and make a referral. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Asperger's syndrome?
Asperger's syndrome was once its own diagnosis. It described people on the autism spectrum with typical intelligence and no delay in speech. Doctors no longer use it as a separate term. Doctors now group it with autism spectrum disorder, or ASD. ASD appears very early in childhood. It affects social skills, communication, and behavior.
Many people still use the name Asperger's to describe themselves. The traits it describes are still recognized. They are now seen as one part of the autism spectrum, which varies from person to person. Signs such as reduced eye contact can sometimes be seen before age 2. The condition is usually diagnosed between ages 2 and 4.
Symptoms
People once diagnosed with Asperger's syndrome often share certain traits. These vary widely and include:
- Difficulty reading nonverbal cues, such as eye contact, facial expressions, and gestures.
- Trouble with tone of voice, figures of speech, humor, or sarcasm.
- Being rigid about routines and upset by changes in schedule.
- Trouble with loud noises or bright lights.
- Intense, focused interests, with deep knowledge of specific topics.
- Speaking well but in an unusual way, such as a flat voice or odd topics.
People with ASD also have a higher risk of anxiety, depression, and eating disorders. Some have obsessive-compulsive disorder. It causes unwanted repeated thoughts and actions.
Causes and who gets it
The exact cause is not known. Genes play a large role. Genetic factors are estimated to contribute 40 to 80 percent of ASD risk. Changes in many genes are linked to ASD. Most have only a small effect on their own. Other factors also play a part. These include the parents' age and problems at birth. ASD tends to run in families. It is more than four times as common in boys as in girls.
How doctors diagnose it
Doctors diagnose ASD by watching behavior and asking about the child's growth. The team may include a child neurologist (a brain doctor), a speech expert, and other mental health and therapy experts. The evaluation tests thinking, speech, and daily living skills. Screening is recommended at well-child visits, with autism screening at 18 and 24 months.
Treatment
Care for ASD focuses on building skills and supporting the person's needs and strengths. Care works best when it starts soon after diagnosis. People may work with therapists. These experts may focus on behavior, education, daily life skills, or speech. These programs help people learn social, communication, and language skills. They also help with daily living, school, and work. Many people on the spectrum have strengths too. They may learn things in detail, remember information for a long time, or do well in math, science, music, or art.
A doctor may prescribe medicines for specific symptoms. These can include anxiety, depression, or irritability. Support for adults can include job coaching and housing help.
When to see a doctor
Talk to a doctor if a child makes little eye contact, does not respond to their name, or has delays in development. Early checks help families get support sooner. Depression and anxiety are common in people on the autism spectrum. If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can refer you to specialists and manage long-term needs over time.
Common questions
Is Asperger's syndrome still a diagnosis?
No. Doctors now group it with autism spectrum disorder. It was once used for people on the spectrum with typical intelligence and no delay in speech. Many people still use the term to describe themselves.
What causes Asperger's syndrome?
The exact cause is unknown. Genes play a large role. They contribute an estimated 40 to 80 percent of ASD risk. The parents' age and problems at birth can also affect risk.
Can Asperger's syndrome be cured?
Not usually. ASD can be a lifelong condition, but treatments, services, and supports can improve health, well-being, and daily functioning. Support and therapy can help people learn skills and build on strengths at every age.
Do medicines help?
Yes, for some symptoms. Doctors may prescribe medicines for certain symptoms, like anxiety or irritability. Supports and therapies are tailored to each person, since there is no single best approach.
