Understanding Impulsive BPD: The Core of Reactive Living

What is Impulsive BPD?

Impulsive borderline personality disorder (BPD) is a personality disorder that involves reckless and flighty behavior and an underlying fear of abandonment. It’s one possible subtype of BPD, alongside petulant, discouraged, and self-destructive BPD. The subtypes aren’t recognized as formal diagnoses, but some researchers use the subtypes to understand the different ways in which BPD symptoms can manifest.

People with BPD struggle with an unclear sense of self as well as a constant fear that they’ll be rejected and abandoned by loved ones. When it comes to impulsive BPD, a person seeks relief from all that internal pain by engaging in irresponsible behaviors. Perhaps they turn to substance abuse or spending sprees to mask their feelings of emptiness. Or maybe they constantly engage in risky sexual relationships to gain attention and cope with their deep loneliness.

Because they tend to act without thinking, people with impulsive BPD struggle to maintain relationships and function in daily life. For instance, they might fail to hold a steady job, or they might push others away with their hyperactive and unpredictable behavior.

If you or someone you know has BPD, learning more about this subtype can help you understand the ways in which the symptoms can show up and be managed.

Symptoms of the Impulsive BPD subtype

If you have impulsive BPD, your emotional instability and lack of self-control lead to unstable relationships and a chaotic lifestyle. Here are the key symptoms of this BPD subtype:

Flighty. You might be prone to suddenly changing plans without considering how your actions affect others. People see you as unreliable, as you’re constantly cancelling plans or failing to show up for loved ones.

Superficial. Maybe you fake feelings, such as excitement, to get others to like you or pay attention to you. Others might perceive you as over-the-top in the way you express positive emotions. In this way, impulsive BPD can seem similar to histrionic personality disorder.

Easily distracted. People see you as unfocused and hyperactive. You often struggle to maintain interest in activities. For instance, you might impulsively move from one hobby to the next, or perhaps others feel as if you’re never fully present in conversations.

Reckless and potentially self-destructive. Risky actions, such as drunk driving, are common for you. You might also self-harm or frequently have suicidal thoughts.

Periods of hopelessness. When things don’t go your way—for instance, maybe someone ignores you or pushes you away—you fall into deep depression.

Common causes of the Impulsive subtype of Borderline Personality Disorder

Researchers believe that borderline personality disorder develops due to a combination of genetic, biological, and environmental factors. For example, a person’s brain structure or chemistry can make them more likely to act on impulse and struggle with emotional regulation. BPD and other personality disorders can run in families, so these biological issues might be hereditary.

Environmental issues, such as childhood abuse or neglect, can also contribute to the development of BPD. When it comes to impulsive BPD in particular, a chaotic family life might’ve played a role. For instance, perhaps you felt you had to misbehave and act out to receive any level of attention from your parents. That coping strategy could have carried over into adulthood.

Diagnosing the Impulsive BPD type

As a subtype, impulsive BPD isn’t an official diagnosis. However, a therapist or psychiatrist can conduct an assessment and diagnose you with BPD, if your symptoms match certain criteria. Here’s what to expect during the process:

• An assessment of your current moods, relationships, and unhealthy behaviors
• A self-report inventory, such as the McLean Screening Instrument for BPD
• A review of your medical history, including past diagnoses

These types of steps can help a clinician rule out disorders that have some overlapping symptoms with impulsive BPD. For instance, the clinician will want to consider whether you have bipolar disorder, attention-deficit hyperactivity disorder (ADHD), antisocial personality disorder, or histrionic personality disorder.

Treatment and management strategies for Impulsive BPD

If you have BPD or a subtype like impulsive BPD, treatment will likely revolve around psychotherapy. A psychiatrist might prescribe medication to help you control the more disruptive symptoms, but the drugs won’t “cure” BPD.

Here are some psychotherapy approaches that might be used to treat impulsive BPD:

Dialectical behavior therapy (DBT): DBT was designed specifically to meet the needs of people struggling with BPD. A therapist might use some form of this to teach you techniques that reduce impulsive behaviors and improve your emotional regulation.

Cognitive behavioral therapy (CBT): CBT can help you identify and adjust the types of thoughts and emotions that lead to impulsive actions. For example, you might be more likely to act recklessly when you feel frustrated. But if you’re able to recognize your mood shifts, you can then take steps to reduce your anger.

Psychodynamic therapy: Alongside a therapist, you can explore how childhood issues and unconscious thoughts might contribute to your impulsive decision-making. For instance, you might gain insight into your abandonment issues or persistent feelings of emptiness.

If your life and relationships feel chaotic, finding a therapist who can help you manage your symptoms is an important step forward. Whether you meet with a mental health expert in person or connect through an online therapy platform, psychotherapy can improve your self-awareness and help you manage intense emotions.
