Key Takeaways
Autism and BPD are two different conditions, but they can create similar challenges with social and emotional functioning.
In addition to having some overlapping symptoms, it’s not uncommon for autism and BPD to co-occur. When this happens, it’s important to access care that addresses both concerns at the same time.
While there’s no cure for autism or BPD, both conditions can be managed with the right support. Treatment may include therapy and/or medication. However, it will largely depend on the severity of a person’s symptoms and their individual needs.
Autism spectrum disorder (ASD), or autism, is a neurodevelopmental condition. It can cause ongoing challenges with communication and learning, repetitive behavior, and restricted interests. Borderline personality disorder (BPD) is a different mental health condition and BPD is not a form of autism. BPD can lead to emotional instability and impulsivity. It can also affect how people see themselves and their ability to form healthy, stable relationships.
Both autism and BPD can cause similar difficulties with interpersonal and emotional functioning. They can also co-occur, meaning a person can live with both conditions at the same time. This overlap can make it difficult to know whether a person is living with autism, BPD, or both.
So if you’re having trouble managing your emotions, relationships, or any other important aspects of your life, don’t hesitate to ask for your help. A therapist can talk to you about your symptoms, provide an evaluation, and help you get the support you need to manage your mental health.
Can autism look similar to borderline personality disorder?
Yes, autism can look similar to BPD. Let’s review a few examples of symptoms that can be characteristic of either condition.
Social interaction: Both autism and BPD can negatively impact social skills and your ability to show empathy. This can make it hard to maintain relationships.
Emotional regulation: Autism and BPD can affect your ability to manage, identify, and express emotions. These conditions can also make it difficult to understand other people’s emotions and respond appropriately.
Repetitive behaviors: People with autism may engage in repetitive behaviors to relieve stress or just for fun. Repetitive behaviors can be mistaken for impulsivity in people with BPD.
Self-harm: Both autism and BPD can elevate a person’s risk for self-harm and suicidality.*
Restricted interests: People with autism and/or BPD may be more likely to have rigid ways of thinking or intense interests.
*A note on safety: If you’re having thoughts of harming yourself, don’t hesitate to ask for help. You can contact the National Suicide and Crisis Lifeline by dialing 988 from any phone. Their counselors will provide confidential support and resources to help keep you safe.
How can you tell the difference between BPD and autism?
While BPD and autism can look similar on the surface, there are several differences that can help you tell them apart. Here are four areas where they differ:
When symptoms begin: Autism is usually noticeable in early childhood, often before a child starts school. BPD symptoms typically appear much later, in the teen years or early adulthood.
How relationships are affected: People with autism may have difficulty with reading social cues or understanding unspoken rules, which can make relationships challenging. People with BPD often have intense fears of abandonment and unstable relationship patterns.
How emotions are regulated: Emotional overwhelm in autism often comes from sensory overload or unexpected changes. Emotional swings in BPD are usually tied to relationship stress, rejection sensitivity, or fear of being left.
How behaviors show up in daily life: Autism may involve repetitive behaviors, strict routines, or stimming as a way to self-soothe. BPD may involve impulsive behaviors, self-harm, or sudden shifts in how someone sees themselves or others.
These differences can be subtle, and it’s common to feel unsure about what fits your experience. A trained mental health professional can help you sort through your symptoms and find the right support.
Can you have autism and BPD together?
It’s possible to have autism and BPD together, and research suggests it’s not uncommon. While there’s limited data on the prevalence of this experience, one study found that as many as around 15% of people with BPD likely also have autism.
Experts are still working to understand the connection between these conditions. While having one won’t automatically lead you to develop the other, they may result from similar risk factors. There’s evidence to suggest that both BPD and autism may be tied to similar biological, environmental, and genetic differences.
Can one condition be misdiagnosed as the other?
Because autism and BPD share some symptoms, it’s possible to receive a misdiagnosis. This can prevent a person from receiving the care they need. This is especially true for women and girls, who are more likely to mask their autistic traits by copying social behaviors, staying quiet, or overworking to “fit in.” Masking can hide early signs of autism and lead mental health professionals to focus on later life challenges, like emotional overwhelm or relationship instability, which may look more like BPD at first glance.
On the other hand, the intense emotions and interpersonal challenges seen in BPD can sometimes be mistaken for autism, especially when someone also experiences sensory overload or social anxiety. Missed diagnoses can delay the right care and make it harder to understand your own experiences.
If you think you received a misdiagnosis in the past, don’t hesitate to speak to your provider or seek another opinion. You deserve an accurate understanding of your mental health and a provider who listens, asks thoughtful questions, and helps you access the support you deserve.
Personalized care for BPD and ASD
Treatments for BPD and autism vary considerably and are largely dependent on the severity of a person’s symptoms and their individual needs. But fortunately, if you’re living with both conditions, there are treatments that can address both concerns at the same time.
For example, mentalization-based therapy has been shown to have a positive effect on both autism and BPD. This approach focuses on helping people foster emotional regulation and empathy. It can also help people understand thoughts, feelings, and behaviors in themselves and others.
While there’s no cure for autism or BPD, they can be managed with the right support, and some people may require lifelong care. There’s also evidence to suggest that having co-occurring BPD and autism may increase your risk of severe depression and suicidality. In those instances, it’s important to prioritize safety planning in treatment.
Currently, there are no approved medications for autism or BPD. But for some people, medication can be helpful in alleviating symptoms of co-occurring conditions, like depression. You can always talk to your provider about whether this is the right option for you.
