What is Borderline Personality Disorder?
Borderline personality disorder, known as BPD, is a common mental health condition. It is a type of emotionally unstable personality disorder that can significantly affect a person’s personal and social well-being. Understanding its nature is a vital step toward seeking appropriate support and beginning a journey towards stability.
Personality disorders vary, and some people may not fit neatly into a single category. They might show signs of BPD alongside characteristics of other types. Recognising this complexity is important for a comprehensive approach to diagnosis and ongoing support.
What is BPD & Addiction as a Co-Occurring Disorder?
A co-occurring disorder, often called a dual diagnosis, means a person is living with both a mental health condition and a substance misuse issue simultaneously. For borderline personality disorder, or BPD, and addiction, this means the challenges of BPD exist alongside drug or alcohol dependence. These conditions interact, often making the symptoms of both more complex.
People with BPD may use substances to cope with intense emotions or impulsivity, creating a cycle where substance misuse worsens BPD symptoms. Comprehensive treatment requires addressing both the BPD and the addiction together, as each can influence the other’s progression and recovery. Having both BPD and a substance use disorder can be challenging, and seeking help can be even harder. Fortunately, treatment for addiction with BPD as a dual diagnosis is available in the UK.

Signs of Borderline Personality Disorder and Its Link to Addiction
In the UK, medical professionals diagnose borderline personality disorder based on a specific set of symptoms. These often include intense emotional swings, impulsive behaviours, unstable relationships and a distorted self-image. It is important to know that a person does not need to exhibit every single symptom to receive a diagnosis.
People can express many different behaviours and signs, including:
Negative thoughts and feelings
- Variable mood or mood swings
- Feeling empty or unworthy
- Fear of abandonment
- Difficulty accepting criticism
- Unclear identity, including self-expression or sexual preference
Challenging behaviours
- Creating intense and unstable relationships with others
- Acts of self-harm
- Outbursts of emotion
- Being disruptive in social situations
- Impulsive acts
Anyone might display symptoms associated with borderline personality on occasion. However, such instances alone do not diagnose BPD. A diagnosis hinges on a persistent pattern of instability in relationships, self-image and emotions, alongside marked impulsivity or self-harming behaviours. Characteristics include symptoms which are consistently intense and disruptive to daily life. They may be:
- Present all the time, including in personal and social situations
- Causing severe distress to the person experiencing them
- Perceived by others as extreme or unusual
- Still present and have been since childhood
- Resulting in challenges like losing a job or a loved one
Free Assessment for BPD and Addiction
We offer free BPD and substance addiction assessments as part of our admissions process.
Relationship Between Borderline Personality Disorder and Substance Misuse
People with borderline personality disorder (BPD) can be at a higher risk of developing an addiction. The intense emotional dysregulation and impulsivity often associated with BPD may lead to substance misuse as a coping mechanism. This can create a challenging cycle, where addiction might worsen BPD symptoms and vice versa. [2]
Addiction is when a harmful habit or behaviour becomes difficult to stop. There are substance and non-substance types of addiction. [3] Substance addiction refers to dependency on a harmful substance, such as drugs or alcohol. A non-substance addiction refers to an addiction to a certain behaviour, like gambling or shopping. There is a clear link between addiction and BPD, as around 78% of people with BPD may develop an addiction to drugs or alcohol at some point. Roughly 25% of people with addiction will have BPD. [2]

Common Addictions for People with BPD
People living with borderline personality disorder can develop a range of addictive behaviours, encompassing both substance and non-substance addictions. This broad spectrum highlights the varied ways addiction may manifest when co-occurring with BPD, affecting different areas of a person’s life.
Addictive substances generally fall into two categories: sedatives and stimulants. Some of these substances are legally prescribed medications, accessed through a doctor. Others are obtained illicitly, commonly referred to as street drugs. Understanding these distinctions helps clarify the diverse nature of substance misuse.
Sedative substances, which can lead to addiction for people with BPD, include alcohol and various opioids such as heroin, tramadol or oxycodone. Benzodiazepines like diazepam and Valium also fall into this category. Such substances depress the central nervous system, often creating a calming effect that can become dangerously addictive.
People with BPD can also develop non-substance addictions, involving compulsive behaviours or habits rather than drug or alcohol misuse. This includes gambling addiction, gaming addiction or shopping addiction. Love or sex addiction and social media addiction are also common. Eating disorders can also represent a form of non-substance addiction.

Why BPD Can Lead to Substance Misuse
It’s understandable to wonder why someone living with Borderline Personality Disorder might develop an addiction. Often, these behaviours begin as a way to cope with challenging symptoms. Addictive substances or activities can temporarily lessen negative feelings or intensify positive ones, providing a momentary escape from emotional distress.
People with BPD may also experience higher rates of physical illness. In such cases, they might turn to substances seeking relief from physical discomfort, leading to a cycle of continuous self-medicating. This can unfortunately progress into drug misuse and ultimately addiction. Furthermore, a natural desire to boost mood, perhaps due to lower levels of certain euphoric signalling molecules, can also play a part.
There’s a notable overlap between BPD and substance misuse, with many similarities between the two conditions. Certain symptoms of BPD, such as impulsivity and difficulty controlling mood, can directly contribute to and even worsen addictive behaviours. Research highlights this connection, with one study indicating that 42% of people with alcohol addiction also meet the criteria for BPD. [5]
Borderline Personality Disorder and Addiction Diagnosis
Having a dual diagnosis, also known as a co-occurring disorder, means a person has received a diagnosis for two separate conditions. Being diagnosed with borderline personality disorder alongside alcohol or drug addiction is one such dual diagnosis. A specialist doctor will conduct a thorough assessment, reviewing a person’s emotions, behaviours and thoughts, and discuss how certain symptoms have affected their life.
Before making any diagnoses, doctors will rule out other conditions. This might involve further consultations or medical investigations such as blood tests. Arriving at the correct diagnosis is crucial, as it allows people to receive the most appropriate and effective treatment for their co-occurring BPD and substance misuse challenges.
Treatment for Borderline Personality Disorder and Addiction
Many addiction treatment options exist for borderline personality disorder and co-occurring substance misuse. It is often beneficial for people with dual diagnoses to receive care at a medical facility. This environment can help manage complex symptoms more effectively during their recovery journey.
Addressing both BPD and addiction can be particularly challenging. A medical professional should always assess your needs before treatment begins. This helps confirm that appropriate support is in place. Recovery paths vary, and there is no quick cure, but with patience and time, you can learn to manage your conditions.

This type of care helps ensure that a person’s mental health challenges receive the same dedicated focus as their addiction recovery. Dual diagnosis treatment for BPD and addiction helps prevent a cycle where one condition worsens the other. It supports a more comprehensive and sustainable path to overall well-being.

Therapies for BPD and Addiction
Evidence suggests that treating both borderline personality disorder and addiction simultaneously significantly improves outcomes. Care typically involves two main approaches: pharmacological (using prescribed medications for symptoms) and psychological treatment. Psychological therapy, particularly dialectical behavioural therapy (DBT), is often central, helping people recognise and manage harmful thoughts.
DBT can be delivered individually or in group settings, helping to develop a sense of community and motivating people towards their treatment goals. Professionals can also provide other forms of drug or alcohol treatment, based on a person’s specific needs. Examples include family therapy, trauma therapy, holistic practices or relapse prevention groups.
