Personality disorders involve personality traits that differ markedly from societal norms, often emerging in childhood. Antisocial personality disorder involves disregard for others, aggression, deceitfulness, impulsivity, irritability, recklessness and lack of remorse. It is defined in the DSM-IV and ICD-10 and commonly diagnosed more in males. Those with ASPD are at risk for substance abuse, depression and other disorders. Genetics play a role and biological relatives of those with ASPD are also at higher risk. Treatment involves psychotherapy and medication management to increase self-awareness and move towards a healthier perspective.
