Key Takeaways
- Psychiatrists and psychiatric mental health nurse practitioners (PMHNPs) both specialize in mental health. They can diagnose autism and other concerns.
- Getting diagnosed with autism as an adult can bring up some mixed emotions. For some people, it can be validating and empowering. For others, it can open the door to life-changing care.
- High costs and the availability of providers can be barriers to autism care. But sliding-scale clinics and virtual psychiatry can improve access to the support you deserve.
If the idea of seeking an autism spectrum disorder (ASD or autism) diagnosis feels a little overwhelming, know that you’re not alone. Many people approach this process with mixed emotions. Just know that these feelings are valid, and support is available.
While pursuing an autism diagnosis is a personal decision, there are people who can help along the way. For example, you might be wondering whether a psychiatrist can diagnose autism. The answer is yes. Both psychiatrists and psychiatric mental health nurse practitioners (PMHNPs) can provide a detailed assessment of your physical and mental well-being and provide an autism diagnosis if appropriate.
Whether you have autism and/or other conditions, a psychiatric provider can help ensure that you get the right treatment for your needs.
What to know before pursuing an autism evaluation
There are many reasons to consider getting an autism diagnosis as an adult. Perhaps a medical provider, therapist, or loved one suggested it. Or maybe you’re noticing some possible signs of autism in yourself. As you consider an evaluation, keep in mind that autism is a form of neurodivergence. It can affect people in many different ways, and it doesn’t always require treatment.
Some people are understandably hesitant to pursue a later-in-life autism diagnosis. For example, if you already know how to manage your challenges, you might ask yourself, “What’s the point?” The answer to that question is highly personal. For some people, receiving a diagnosis can be empowering and normalizing. For others with more significant needs, getting diagnosed can be life changing. It can be an important first step in meaningfully improving their daily functioning.
Remember, you ultimately get to decide what’s best for you. But if you decide to seek an autism diagnosis, working with a psychiatrist can provide some unique advantages.
Both psychiatrists and PMHNPs specialize in mental health and can prescribe medication. They’re skilled in identifying both physical and mental health conditions. This means they can rule out underlying medical issues that look similar to autism to ensure that you receive the right diagnosis.
In addition, people with autism can also have other mental health conditions, like depression or anxiety. Having a preexisting relationship with a psychiatric provider can make it easier to get treatment for those conditions.
The care you need, when you need it

How a psychiatrist diagnoses autism
When evaluating someone for autism, a psychiatrist or PMHNP will refer to the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). This publication outlines the official diagnostic criteria for the condition. A psychiatrist diagnoses autism by determining whether a person meets these criteria.
During your evaluation, your provider will ask many questions about your symptoms. They’ll want to know when your symptoms first started, what makes them better or worse, and how they affect your life today.
One of the challenges during this part of the process is that, for a diagnosis, autism symptoms must be present during childhood. As an adult, it can be tough to remember details of your early life. So some providers talk to parents or other family members to fill in the gaps. If that’s not possible, it’s OK. Your provider can also use their observations and a formal assessment to help them determine whether you’re autistic.
Getting an autism evaluation is usually a multi-step process. For example, in addition to meeting with your psychiatric provider, you might also need to see a primary care doctor or get some blood work done. Other factors that may affect your timeline can be your access to providers, the presence of co-occurring conditions, and whether you’re seeing a specialist. If your psychiatric provider feels that they can’t make an accurate diagnosis, they’ll refer you to neurological psychiatric testing to help aid in the diagnosis.
Some providers may be able to issue a diagnosis in a few appointments, and others may need more time. While this can be frustrating, try to have patience with yourself and your care team throughout the process. But if you’re not feeling supported or you don’t agree with the diagnosis you receive, it’s OK to get a second opinion.
Overcoming barriers to an autism diagnosis
For many people, the main barrier to getting an autism diagnosis is the availability of in-network providers. This is due to the ongoing nationwide shortage of mental health professionals. Some people report waiting months to see a psychiatric provider who takes their insurance. It can also be harder to find a provider who specializes in autism in adults.
The high cost of care can also be a barrier. Insurance coverage for autism support can vary depending on your plan. Paying out of pocket might not be possible because these services can be expensive.
If you’re having a hard time accessing the support you need, talk to your doctor or other provider(s). They can help you brainstorm solutions. For example, there might be organizations that provide income-based payment options, like sliding-scale clinics. You might also want to consider a telehealth option, as psychiatrists can diagnose autism virtually. Virtual options can provide quicker, easier access to the care you deserve.
An adult autism diagnosis is simply a way for you to better understand yourself and learn how to cope with and adapt to your neurodivergence. There are no specific medications to treat ASD, but some medications can help with irritability and/or co-occurring conditions.
