Personality Disorders & Substance Abuse | Co-Occurring Disorders

Personality disorders are a group of mental health conditions that can make it difficult to navigate everyday life.

If you’re diagnosed with a personality disorder, you may experience enduring patterns of behavior, cognition, and inner experience that deviate significantly from what’s expected. These patterns can cause significant distress or impairment in personal, social, and occupational functioning.

The Different Types of Personality Disorders

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) recognizes ten distinct personality disorders, categorized into three clusters to help understand common themes.

It's important to remember that these are just categories; every person's experience may not perfectly fit into one group. Personality disorders can also often co-occur with other mental health conditions, such as depression, anxiety disorders, and substance use disorders, which can complicate diagnosis and treatment.

Only a trained professional can make an accurate diagnosis for you using a comprehensive clinical assessment. Still, here are some characteristics and general signs that might suggest a personality disorder:

Cluster A: Odd or Eccentric

People in this group may struggle with trusting others and forming close relationships.

Cluster B:  Dramatic, Emotional, or Erratic

People here might have trouble following rules, experience intense and unstable emotions, or have an inflated sense of self-importance.

Cluster C:  Anxious or Fearful

People with these disorders often experience excessive shyness, social anxiety, or a strong need for approval and support from others.

If you notice patterns in yourself or someone you care about, encourage seeking professional help. Personality disorders are treatable, and you can lead a fulfilling life with the right support.

Diagnosis of Personality Disorders

There's no single test for personality disorders. Instead, a mental health professional will get to know your past experiences and current symptoms. 

Fortunately, personality disorders are usually diagnosed in late adolescence or early adulthood, so you can get help early on. Here's an overview of the diagnostic process and treatment options:

• Clinical assessment: A mental health professional will take a comprehensive history, explore your current symptoms, and consider patterns of behavior, thoughts, and emotions throughout your life. They might use specialized questionnaires and interviews.
• Differential diagnosis: It's important to rule out other possible medical or mental health conditions that might present with similar symptoms. This process ensures you get the most appropriate treatment.
• DSM-5 criteria: Mental health professionals refer to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose. The DSM-5 outlines specific criteria for each personality disorder, and your symptoms will be assessed against those criteria.

How Common are Personality Disorders?

Personality disorders are surprisingly common, affecting up to 1 in 10 people. This number jumps to 40 to 60% of those already seeking mental health care.

Certain disorders, like obsessive-compulsive and paranoid personality disorders, are more prevalent than others, while narcissistic personality disorder is less common.

Men are more likely to be diagnosed with antisocial and schizoid disorders, while women are more often diagnosed with borderline and dependent disorders. However, these gender differences might be due to biases in diagnosis.

It's important to remember that these are mental health conditions, not character flaws or moral failings.

Treatment of Personality Disorders

Personality disorders often have a chronic course but can vary in severity over time. Early diagnosis and intervention are crucial for improving long-term outcomes.

They can be effectively managed with a combination of treatment approaches. These include:

• Psychotherapy: Evidence-based modalities, such as Dialectical Behavior Therapy (DBT), are the cornerstone of treatment for personality disorders. Other effective therapies include Cognitive Behavioral Therapy (CBT) and Schema Therapy.
• Dual diagnosis treatment: A treatment program that addresses co-occurring mental health conditions alongside addiction.
• Team approach: While individual psychotherapy is essential, managing complex personality disorders sometimes requires a collaborative team approach. This might involve psychiatrists for medication management (if warranted), therapists specializing in specific areas, and family or group therapy to promote support and understanding.
• Pharmacotherapy: While medication is not the primary treatment for personality disorders, it can be useful in managing co-occurring conditions like depression, anxiety, or mood dysregulation. Commonly prescribed medications include selective serotonin reuptake inhibitors (SSRIs), mood stabilizers, and atypical antipsychotics.
• Support groups: Organizations like Narcotics Anonymous (NA) provide a much-needed community to help maintain sobriety after treatment.
• Challenges: Treating personality disorders can be challenging for several reasons. Those affected might take time to build trust with a therapist, and deeply ingrained patterns of thought and behavior take time to change. However, significant improvement and a better quality of life are attainable with the right treatment and commitment.

Seeking help and taking the first step toward getting a thorough diagnosis is an incredibly brave act. Reaching out to a qualified mental health provider can open the door to healing and support.

Causes and Risk Factors of Personality Disorders

Personality disorders may seem confusing, and it's natural to wonder what causes them. The truth is, there's no single answer.

They're likely a combination of genetics, environment, and how you develop as a person, especially during your childhood and teenage years.

Here's a breakdown of the key factors involved:

Genetic Factors

Research suggests that genetics play a major role in the development of personality disorders. Certain genes may predispose you to personality disorders, making you more vulnerable to environmental triggers.

For instance, traits such as high openness to new experiences, low conscientiousness, and low agreeableness could potentially lead to disorders like antisocial personality disorder if life circumstances push these traits to extremes.

Moreover, having close relatives with Borderline Personality Disorder (BPD) can increase the likelihood of developing the disorder by up to five times.

Environmental and Developmental Influences

Environmental factors, particularly those experienced during early childhood, are critical in developing personality disorders.

Stressful and traumatic events, such as abuse or neglect, can significantly impact your personality development.

For example, people with BPD are 13 times more likely to report childhood trauma compared to those without mental health problems, with a high prevalence of physical neglect and emotional abuse reported among those diagnosed with BPD.

Other Risk Factors

Other risk factors have been identified that increase the likelihood of developing personality disorders:

• Dysfunctional upbringing: A lack of constructive criticism or excessive praise could foster narcissistic personality disorder, while extreme shyness and feelings of inadequacy can lead to avoidant personality disorder.
• Substance abuse: Substance abuse and addiction often coexist with personality disorders and can exacerbate symptoms or create additional problems.

The science of personality disorders points towards a complex interaction. It's not just your genes or childhood but how they combine that shapes your identity.

These diverse factors help break down stigma and provide a framework for developing better support and treatment options.

The Link Between Personality Disorders and Substance Abuse

Personality disorders and substance abuse can be like two sides of the same coin, often appearing together and making life difficult. Imagine struggling with intense emotions, trouble forming relationships, or feeling you can't trust anyone.

These are some of the challenges people with personality disorders face. Now, add in the problems of addiction. It's a double challenge, and it's surprisingly common.

Can BPD Lead to Addiction?

Out of all the personality disorders, BPD is the one most likely to show up alongside addiction. People with BPD may struggle with unstable relationships, impulsive behaviors, and a negative self-image.

These difficulties can make them more likely to turn to substances as a way to cope. The exact reasons why these disorders co-occur are still being researched.

Sometimes, substance abuse might trigger a personality disorder or the other way around. What's clear is that having both makes things worse for each other.
