What causes antisocial personality disorder (ASPD)?

There is no single cause of ASPD, but the following factors may increase a person’s risk of developing the disorder:

  • Biology: People with ASPD may have unusual levels of serotonin. Serotonin is a chemical in the brain that regulates our mood and feelings of happiness.
  • Environment: Trauma or abuse early in childhood increases the risk of developing ASPD later in life.
  • Genetics: There may be some genetics factors that can predispose some individuals to develop ASPD. However, there is no one genetic factor that is thought to be responsible for the condition.
  • Lifestyle: About half of people with ASPD also have problems with drug or alcohol abuse.
  • Sex: Men are more likely than women to develop ASPD.
