ADHD & Narcissism: Understanding the Connection

What Is ADHD?

Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects focus, self-control, and organizational skills. ADHD affects over 10% of children and 4.4% of adults.³ ADHD symptoms are categorized into three types: inattentive, hyperactive/impulsive, or combined presentation.

According to the DSM-5, the symptoms of ADHD include:⁴

• Persistent trouble focusing and paying attention
• Making careless mistakes or overlooking details
• Seeming to not listen when spoken to
• Not following instructions or following through on tasks
• Difficulty organizing tasks and activities
• Avoidance of tasks that require sustained attention
• Losing or forgetting things
• Fidgeting or trouble sitting still
• Often being ‘on the go’ or acting as if ‘driven by a motor’
• Talking excessively or interrupting people

What Is Narcissistic Personality Disorder (NPD)?

Narcissistic personality disorder (NPD) is a personality disorder that is characterized by arrogance, impulsivity, defensiveness, and a deep need for external validation. While everyone possesses some traits of narcissism, only about 6% of the population has NPD.⁵ People with NPD often also struggle with a lack of empathy which can cause interpersonal difficulties. At the extreme, some narcissists use, exploit, or even abuse others to get what they want through manipulation tactics, gaslighting, and narcissistic abuse.^{4, 6}

According to the DSM-5, the symptoms of NPD include:⁴

• A sense of grandiosity or excessive self-importance
• Recurrent fantasies of being powerful, successful, beautiful, or important
• Beliefs of being special and exceptional (and seeking out people of similar or higher ‘status’ or ‘importance’ as them)
• Excessive need for validation, praise, and admiration from others
• A sense of entitlement or feeling like they deserve special treatment
• Exploiting others for personal gain or selfish reasons
• Unable or unwilling to identify with the needs of others (empathy)
• Being envious of others or believing others are envious of them
• Arrogant or haughty behavior, acting better than others

Comorbidity of ADHD & NPD

It is possible to be diagnosed with both ADHD and NPD. Studies have shown that having adult ADHD makes someone more susceptible to cluster B personality disorders, including narcissistic, antisocial, and borderline personality disorder.^{1, 2} While there is a lot of conclusive research linking ADHD to BPD and ASPD, there is a little bit of research that shows that people with ADHD are more likely to develop NPD than the general population.

It’s important to understand that just because two conditions occur together, it doesn’t mean one causes the other. Current evidence suggests that people with ADHD are not inherently more prone to developing NPD. Rather, any overlap in symptoms might be attributed to common risk factors, genetic tendencies, or environmental influences.^{1, 2}

Similarities & Differences Between ADHD & NPD

Sometimes, people are diagnosed with both NPD and ADHD. However, it is also possible for these conditions to be confused because of overlapping symptoms and similarities between narcissistic and ADHD tendencies.^{1, 2}

While there are some similarities between both disorders, there are inherent differences between the two.⁷ NPD is a personality disorder that causes abnormalities in the way people think, feel, and behave, and tends to have broader consequences in a person’s life.⁴ ADHD is a neurodevelopmental disorder that is believed to be caused by poor executive functioning and cognitive impairments that tend to mostly affect work, school, and task completion.⁴

Key similarities and differences between ADHD and NPD include:

Symptoms

The symptoms of both ADHD and NPD can overlap a lot, but the two disorders are actually very different. ADHD symptoms can cause people to become easily distracted, forgetful, and off-task, resulting in problems at work, school, and even in daily life. While people with NPD often struggle with these same tasks, these tendencies are linked to other traits like a lack of empathy, entitlement, or an inability to take accountability for actions.^{4, 6} For example, someone with ADHD may appear disinterested in a conversation because they’re easily distracted, while someone with NPD may do so because they lack empathy for others.^{4, 5, 6, 7, 9}

Possible Causes

Both NPD and ADHD have a genetic link, and having a family member with the disorder makes someone more likely to develop it later on in life.^{1, 2, 6, 7} However, there are important differences in the causes of NPD and ADHD. Researchers have found that ADHD is mainly caused by neurological problems in the areas of the brain responsible for learning, memory, decision-making, and concentration.^{3, 4} NPD, on the other hand, is more closely linked to early childhood trauma, specifically overly neglectful and strict parenting or parental overprotection.

Treatment Options

ADHD is considered much more treatable than NPD. The most common treatments for adult ADHD include a combination of therapy and, when needed, medication to improve focus and concentration. Studies on NPD have not been able to identify successful, research-backed approaches that have shown consistent success in treating NPD. Additionally, individuals with NPD are less likely to seek therapy, and when they do, they often discontinue early or are disingenuous in ways that prevent progress.^{3, 5, 6}

How to Receive the Proper Diagnosis

Receiving a proper diagnosis of narcissistic personality disorder versus ADHD involves a thorough and careful evaluation by a qualified mental health professional, typically a psychologist or psychiatrist. The first step is to consult a professional experienced in diagnosing both NPD and ADHD, as they can best distinguish between the two and their overlapping symptoms. The evaluation process usually involves reviewing your detailed medical and psychological history, completing behavioral questionnaires, and possibly interviewing family members or close friends to gather additional perspectives.

There are many different online therapy platforms that can match you with a qualified therapist. Services like BetterHelp or Talkspace offer convenient access to professionals who can conduct evaluations and provide ongoing support from the comfort of your home. These platforms often allow you to choose therapists based on their specialties, ensuring you find someone experienced with both ADHD and NPD.

How Are Comorbid ADHD & NPD Treated?

Managing co-occurring disorders takes a layered approach to make sure all the symptoms and challenges of each condition are addressed. While there’s no evidence-based treatment for NPD yet, treating ADHD might help people who have both conditions.^{3, 5, 7} ADHD medications, especially stimulants, can boost cognitive function, learning, memory, and concentration. This can also help reduce impulsivity and improve daily life for someone dealing with both ADHD and NPD.³

Therapies for comorbid NPD and ADHD may include:^{5, 6}

• Cognitive behavioral therapy (CBT): For ADHD, CBT might focus on time management, organization, and impulse control. For NPD, the focus would be on increasing self-awareness, understanding others’ perspectives, and reducing narcissistic behaviors.^{5, 7}
• Dialectical behavior therapy (DBT): DBT may help individuals with NPD manage intense emotions and reduce harmful behaviors while also providing strategies for managing ADHD symptoms like impulsivity and distractibility.
• Schema therapy: Schema therapy addresses old, irrational, or dysfunctional core beliefs, which have been found to play a role in both ADHD and NPD.²
• Family therapy: Family therapy helps to address communication, relationship issues, and conflicts that may be caused or worsened by ADHD or NPD symptoms. In some cases, couples counseling can be beneficial as well.
• Mindfulness-based therapies: Therapies like mindfulness-based cognitive therapy (MBCT) can reduce the impulsivity and inattentiveness associated with ADHD and may help individuals with NPD become more aware of their thoughts and behaviors.
