Studies reveal that antisocial personality disorder (APD) is a result of the abnormal functioning of the nervous system. In addition, mothers who smoke during pregnancy may give birth to offspring who are prone to developing APD. This is because smoking lowers the oxygen supply during the fetus development giving rise to problems in development of brain.
Research on brain imaging reveals the APD is also caused by abnormal functioning of the human brain. In addition, the abnormal functioning of serotonin, the neurotransmitter, is linked to the aggressive or impulsive behavior of certain individuals. Poor behavior could also be a result of problems with the temporal lobes of the brain.
Environmental factors play a huge role in the development of APD in some individuals. Children having a troubled childhood are more prone to antisocial behavior. Studies reveal that the parents of many of the APD victims were alcoholics, criminals or had troubles in marital life. Some of the parents were divorced and the environment at home was not very peaceful.
Sometimes, young children who are deprived of family bonding, trust and love develop APD as they are constantly insecure. Inadequate supervision or guidance from the parents and inappropriate discipline also gives rise to APD. This is the reason children coming from broken homes tend to be more aggressive and antisocial than those children coming from an amicable home environment.
Furthermore, child abuse and antisocial behavior are found to be closely interlinked because these children grow up in a neglected environment and face violent situations during their young years which turn them very aggressive.
