Impulsive borderline personality disorder (BPD) is one of the subtypes of BPD. It’s marked by behaviours that are fast, intense and often hard to control. People with this subtype may act on urges quickly, without thinking through the consequences. This can affect relationships, safety and day-to-day life.
Living with impulsive BPD doesn’t mean someone is “bad” or “reckless.” These behaviours usually come from deep emotional pain and a need to feel something different—right now. If you or someone close to you has this subtype, it can be confusing and exhausting at times. But with the right understanding and support, it is manageable.
In this article, we’ll explore what impulsive BPD is, how it shows up and ways to cope with it.

Understanding impulsive BPD as a subtype
Borderline personality disorder is a complex mental health condition. It affects how a person relates to others and how they see themselves. There are several proposed subtypes of BPD, and impulsive BPD is one of them. These subtypes aren’t officially used in all diagnoses, but they can help people better understand their specific experiences.
Impulsive BPD is thought to be driven by high energy, intense emotions and a need for stimulation. People with this subtype often act quickly and emotionally, which may include risky or self-destructive behaviours. At its core, impulsive BPD is about difficulty controlling urges and acting without fully thinking things through.
This subtype can overlap with others, like the discouraged or self-destructive types. It’s also common for symptoms to change over time. But understanding this specific pattern of behaviour can help guide treatment and self-awareness.
What impulsive BPD can look like
Everyone is different, and not all people with impulsive BPD will behave in the same way. Still, there are common patterns that often show up.
Risky behaviour
Many people with impulsive BPD engage in risky or thrill-seeking behaviour. This might include:
- Reckless driving
- Binge drinking or drug use
- Spending sprees
- Unsafe sex
- Breaking the law
These behaviours often happen in the moment, without much thought about the consequences. Afterward, the person might feel shame, regret or confusion about why they acted that way.
Quick-changing moods
Like other forms of BPD, the impulsive subtype often comes with mood swings. But these changes may be more sudden and intense. A person may go from calm to furious, or happy to devastated, within minutes. These shifts can be triggered by something small, or seem to come out of nowhere.
Attention-seeking or dramatic actions
Some people with impulsive BPD may act in dramatic or attention-grabbing ways. This is not because they’re being manipulative, but often because they feel overwhelmed and don’t know how else to express it. Actions like storming out of a room, yelling, or making sudden big decisions can be a way of trying to manage big feelings.
Trouble with boundaries
Impulsive BPD can make it hard to maintain steady relationships. A person may become very attached very quickly, then suddenly pull away. They might say things they don’t fully mean in the heat of the moment. Relationships can feel intense, chaotic or unstable.
Difficulty being alone
Because people with this subtype often feel bored or empty when alone, they might constantly seek out stimulation or attention. This can sometimes lead to choices that are not safe or healthy.
Why impulsive behaviours happen
At the root of impulsive BPD is emotional dysregulation. This means a person has trouble managing their emotions in a steady, balanced way. When feelings like anger, sadness, shame or excitement become too strong, the person might try to escape those feelings by doing something sudden.
Many people with BPD also have a history of trauma, neglect or unstable relationships. Acting impulsively can be a learned way of coping with fear, abandonment or low self-worth.
In some cases, impulsive BPD may be mistaken for other conditions like ADHD or bipolar disorder. While there can be some overlap, BPD impulsivity is usually tied to relationships and a deep fear of being rejected or abandoned.
How impulsive BPD affects life
Living with impulsive BPD can be challenging. The fast-paced, emotionally intense nature of the subtype can affect many areas of life.
Relationships
Frequent mood changes, intense reactions and quick attachment can put a strain on relationships. Friends, partners or family members may feel confused, hurt or unsure how to respond. It can also lead to a pattern of unstable or short-lived relationships.
Work and school
Impulsive decisions or emotional outbursts may affect performance at work or school. A person might quit suddenly, lash out at colleagues or struggle to stick with routines. They may also take risks like calling in sick too often or skipping important deadlines.
Health and safety
Engaging in risky behaviours can put a person’s health and safety at risk. This includes substance use, unprotected sex or dangerous driving. Over time, this can lead to physical health problems or legal trouble.
Mental wellbeing
Impulsivity often comes with guilt, shame or self-blame. A person may not fully understand why they behave the way they do. This can lead to depression, anxiety or even thoughts of self-harm or suicide.
Ways to manage impulsive BPD
The good news is that impulsive BPD is treatable. Many people learn to manage their behaviours and lead fulfilling lives. Here are some options that can help:
Therapy
The most effective treatment for BPD is therapy, especially dialectical behaviour therapy (DBT). DBT helps people learn skills to manage emotions, reduce impulsive actions and improve relationships. Other useful therapies include:
- Cognitive behavioural therapy (CBT)
- Schema therapy
- Mentalisation-based therapy (MBT)
A therapist who understands BPD can work with you to find what’s most helpful.
Medication
There’s no specific medication for BPD, but certain medicines can help with symptoms like anxiety, depression or mood swings. These might include antidepressants, mood stabilisers or antipsychotics. It’s best to discuss this with a GP or psychiatrist.
Building coping skills
Learning and practising healthy ways to cope with emotions is key. This might include:
- Deep breathing or grounding exercises
- Delaying action when emotions are high
- Writing thoughts down instead of acting on them
- Reaching out to a trusted friend or support person
The goal isn’t to be perfect, but to gradually gain more control over impulses.
Creating a support system
Having a solid support network can make a big difference. This might include friends, family or support groups. Online communities can also be a helpful way to connect with others who understand.
Self-compassion
It’s important to remember that impulsive BPD is not your fault. You’re not broken or unlovable. Practising self-kindness and being patient with yourself is part of the healing process.
Supporting someone with impulsive BPD
If someone close to you has impulsive BPD, it can be a rollercoaster. You might feel unsure how to help or how to handle sudden changes. Here are some tips:
- Stay calm during emotional moments. Reacting with anger often makes things worse.
- Set clear, loving boundaries. Boundaries are healthy and help build trust.
- Encourage them to seek support, but don’t force it.
- Look after yourself too. Supporting someone else doesn’t mean ignoring your own needs.
Learning about the condition can help you be more empathetic and prepared. Communication, patience and kindness go a long way.
Final thoughts: What is impulsive BPD?
Impulsive BPD is a real and often misunderstood experience. It can feel overwhelming at times, but with the right tools and support, it can be managed. Whether you’re living with this subtype or love someone who is, know that change is possible.
Everyone deserves compassion, connection and hope. If you or someone you know is struggling, don’t hesitate to reach out for help. You’re not alone.
