Borderline personality disorder (BPD) and attention deficit hyperactivity disorder (ADHD) are both considered neurocognitive conditions.

You can have BPD and ADHD at the same time, and both conditions share impulsive behavior as a symptom. Some research suggests that these conditions share certain risk factors as well.

Both conditions can be managed with effective treatment strategies. But, if you have both ADHD and BPD, you may need to adapt your treatment so that you can address all of your symptoms.

Let’s take a look at what we know about the connection between ADHD and BPD.

According to some studies, 14% of people who received an ADHD diagnosis in childhood later received a BPD diagnosis later in life. They estimated that 18 to 34% of adults being treated for ADHD also had BPD. Some personality traits can indicate whether you have both of these conditions.

A 2021 review of studies on borderline personality disorder (BPD) and attention deficit hyperactivity disorder (ADHD) found that impulsive decision-making is a behavior that both conditions share.

People who have both conditions also have difficulty regulating their emotions, according to the review.

An older study published in 2012 grouped 103 women on a scale according to whether they had:

  • ADHD symptoms only
  • BPD symptoms and ADHD symptoms of hyperactivity
  • BPD symptoms and ADHD symptoms of inattention, hyperactivity, and impulsivity
  • BPD symptoms and ADHD symptoms of inattention and hyperactivity

The study identified “high novelty seeking” as a personality trait all these groups have in common. This personality trait can also be described as “thrill-seeking”. But essentially it means a tendency to pursue lots of new experiences that have a high risk or reward and provoke a lot of emotion.

Women in the study who had both BPD and ADHD scored high in harm avoidance and low on cooperativeness and self-directedness (or executive functioning).

Researchers have also found that ADHD in childhood and adolescence could be an indicator of BPD in adulthood.

The two conditions appear to share some genetic components. Also, the environmental trigger for BPD is often trauma or negative childhood experiences, which can be linked to ADHD. There’s also a possibility of misdiagnosis since symptoms of BPD during childhood may resemble ADHD.

Can ADHD meds make BPD worse?

There’s some concern that commonly prescribed medications for ADHD, particularly stimulants, can worsen BPD symptoms.

A symptom of BPD is emotional dysregulation, and stimulants may make it even harder to regulate your emotions. However, there isn’t a lot of research to address this conclusively.

Since some people with ADHD have BPD, more studies are needed to understand how ADHD treatment can affect BPD symptoms.

If you have been prescribed medication for ADHD, make sure your doctor is fully aware of your health history, including BPD or other mental health conditions.

You should speak with your healthcare professional if you feel the medication you’re taking is increasing your BPD symptoms.

ADHD and BPD can have a serious impact on your life. Anyone who has ADHD, BPD, or both can benefit from treatment strategies. But it’s important to note that these conditions have important differences.


BPD can be characterized by patterns of emotional intensity. Some common signs and symptoms of BPD include:

  • fear of abandonment
  • avoidance of pain
  • intense and unstable relationships
  • shifting moods

For many people, untreated BPD can be a condition that makes daily tasks difficult and healthy relationships hard to maintain.


ADHD can impact your ability to organize your life and complete tasks.

ADHD can have an effect on your relationships, your academic career, your workplace success, and your self-esteem.

But at its core, ADHD is more than how you see yourself, it’s a neurodevelopmental condition that affects how the brain manages emotions, motor movements, and attention.

If your ADHD symptoms are not severe, you may be able to manage them without medication or medical treatment. This is not necessarily the case with BPD. Both of these conditions can be diagnosed by a mental health professional.

Sometimes there can be a stigma around BPD, ADHD, and some of the medications treating them. But you should never feel ashamed to get the care you need. Mental health conditions need treatment just like physical conditions.

You should talk with your doctor or a therapist if you experience:

  • regular difficulty focusing on day-to-day tasks
  • difficulty regulating your attention or intense emotions
  • fear of abandonment that impacts your relationships

Treatments for BPD and ADHD may include:

When to seek emergency care

  • desire for or completed acts of self-harm
  • suicidal thoughts

ADHD and BPD have overlapping symptoms. Some people have both conditions.

Researchers think that having ADHD as a child can be an indicator that you’ll develop BPD as an adult.

But having ADHD doesn’t automatically mean you have BPD. More research is needed on the connection between these two conditions.

If you do have both conditions, make sure your doctor and mental health team know about your overlapping symptoms. Treatments are available for BPD and ADHD to help you live a full and healthy life.
