Psychopathy vs. antisocial personality disorder (ASPD)

The term psychopathy describes a disposition toward manipulative or harmful behaviors, combined with a lack of concern or guilt for their consequences.

Antisocial personality disorder (ASPD) is a mental health condition characterized by disregard for the feelings and rights of others. This disregard can lead to criminal behavior in some cases.

There’s quite a bit of overlap between ASPD and psychopathy. But clinically, psychopathy represents only one subset of traits within ASPD.

An estimated  1.2% to 4.5% of the general population exhibits some level of psychopathy.¹

Is psychopathy a mental illness?

Psychopathy is a recognized clinical construct frequently discussed in research and clinical practice. However, it is not a recognized, standalone diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

Some individuals with psychopathic traits may have additional qualities that cause them to fit the diagnostic criteria for antisocial personality disorder (ASPD), which is an official DSM-5 diagnosis.

Psychopathy vs. sociopathy

Sociopathy and psychopathy are often used interchangeably, but they actually describe distinct personality and behavioral traits associated with ASPD.

Psychopathy typically refers to a cluster of personality traits such as lack of empathy, callousness, lack of guilt, and manipulativeness. It’s often assessed in forensic and research settings using tools like the Hare Psychopathy Checklist-Revised.² Psychopathic behavior tends to be more cold, “calculated,” and controlled.

In contrast, sociopathy describes more erratic and impulsive antisocial behavior, often marked by emotional outbursts. While the term is common in popular culture and some clinical discussions, there’s no standardized criteria for assessing or measuring it specifically.

Signs and symptoms of psychopathy

Signs of psychopathy include: 

• Lack of empathy
• Manipulativeness
• Irresponsibility
• Aggressive behavior
• Calculating behavior
• Lack of remorse
• Pathological lying
• Reduced emotion
• Impulsiveness

Examples of psychopathy might include: 

• Not taking responsibility
• Lying with comfort and ease
• Gaslighting others
• Violating boundaries
• Hurting others without remorse
• Appearing fearless in risky or dangerous situations
• Chronic manipulation for personal gain

Can children show signs of psychopathy?

Some studies suggest that certain psychopathic tendencies may be detectable early in childhood, though behavioral problems more commonly emerge in adolescence or young adulthood.³

Psychopathic tendencies in childhood, often called callous-unemotional (CU) traits, could be an indicator that a person may one day meet the diagnostic criteria for antisocial personality disorder.

However, because ASPD cannot be diagnosed until after a person turns 18, childhood signs are thought of as risk indicators, not early psychopathy. Importantly, not all children with CU traits will go on to develop ASPD.

If you’re concerned about your child’s behavior, it’s important to seek professional help. A mental health professional can assess your child’s behavior, identify any underlying issues, and provide guidance and support going forward.

What causes psychopathy?

It’s impossible to pinpoint a single cause of psychopathic traits, or ASPD, in any given person. However, several risk factors are known to increase a person’s likelihood of presenting with them, including:

Genetics: Some studies indicate that certain psychopathic traits have a genetic component.⁴

Brain differences: A study by University of Wisconsin-Madison researchers found that people diagnosed with psychopathy show reduced connectivity between brain regions involved in empathy and guilt, and those that process fear and anxiety.⁵

Early childhood experiences: Growing up in a dysfunctional environment, including living through childhood abuse or neglect, can increase a person’s risk of developing psychopathic tendencies.⁶

Primary vs. secondary psychopathy

Some research distinguishes between two forms of psychopathy:

• Primary psychopathy presents as superficial charm and deliberate, calculated social behavior. It’s been proposed that primary psychopathy is influenced more strongly by genetic factors than environmental ones.⁷
• Secondary psychopathy is thought to develop in response to environment factors like high levels of stress or emotional trauma. It’s associated with high-anxiety, impulsive behavior and emotional reactivity.⁸

Treatment options for psychopathy

Psychopathy can be difficult to treat. But with ongoing effort and guidance from a mental health professional, symptoms can be managed. Treatment often involves a combination of approaches. 

Cognitive behavioral therapy (CBT): CBT addresses the connections between thoughts, feelings, and behaviors. It aims to interrupt harmful patterns triggered by certain thoughts or situations and replace them with healthier ones.

Antipsychotic medication: Some people with psychopathic traits may act aggressively or impulsively. In these cases, antipsychotic medication may be prescribed “off-label” by medical professionals to help reduce these behaviors, although they’re not specifically approved for treating psychopathy.

Mood stabilizers: These medications may also be used off-label to help control agitation and reduce the risk of aggression. But like antipsychotics, they are not approved specifically to treat psychopathy.

Barriers to treatment

Certain traits associated with psychopathy can make treatment particularly challenging:

• Difficulty engaging: People with psychopathy are often manipulative, so they may appear engaged in treatment while not taking it seriously. And because they may have blunted emotions and reduced empathy, they may not see the benefit of treatment and struggle to stay engaged long enough to make progress.
• Limited insight: People with psychopathy may lack the insight and emotional awareness necessary to understand why they need treatment or understand its purpose. Their disregard for social norms and lack of remorse can make it challenging to see why they would need to change.
