What causes dissocial personality disorder?

People with dissocial personality disorder have often grown up with
parental conflict and harsh inconsistent parenting. Their childhoods
have typically featured parental inadequacies and often transfer of
care to outside agencies. Dissocial personality disorder is also
associated with a high incidence of truancy, delinquency and substance
misuse.
Resulting in increased rates of unemployment, problems with housing and difficulties with relationships. Many people
with dissocial personality disorder have a criminal conviction and are
imprisoned or die prematurely as a result of reckless behaviour[3, 4].

Criminal behaviour is central to the definition of dissocial
personality disorder but there is much more to the disorder than just
criminal behaviour. It is often preceded by other long-standing
difficulties (socio-economic, educational, family, relationship).
Psychopathy is considered to be a considerably severe form of
dissocial personality disorder.
