Antisocial Personality Disorder

What is Antisocial Personality Disorder?

Antisocial Personality Disorder (ASPD) is a mental health condition characterised by a pervasive pattern of disregard for and violation of the rights of others. Individuals with ASPD consistently show a lack of empathy, remorse, and respect for social norms, laws, and the rights of other people. This pattern typically begins in childhood or early adolescence and continues into adulthood.

ASPD affects approximately 2-3% of the general population, with higher rates among males (up to 3% in the US) compared to females (about 1% in the US). The condition is associated with significant personal, social, and legal consequences, and individuals with ASPD are overrepresented in criminal justice and substance abuse treatment settings.
