Genetic Factors in the Development of ASPD
The role of genetics in the development of Antisocial Personality Disorder (ASPD) is significant, accounting for approximately 50% of the likelihood of a child developing the condition. If an individual has a parent or sibling with ASPD, their chances of developing the disorder increase, particularly when combined with certain environmental factors. For instance, even adopted children of parents with ASPD can still develop the disorder if they are exposed to negative role models or are not taught to respect the rights and boundaries of others.
Childhood Signs
While mental health professionals do not officially diagnose children under the age of 18 with Antisocial Personality Disorder (ASPD), it is worth noting that around 80% of individuals begin to exhibit symptoms by the age of 11. The diagnostic criteria for ASPD includes a prior diagnosis of conduct disorder before the age of 15. Additionally, children who have been diagnosed with conduct disorder, attention deficit disorder, or hyperactivity disorder before the age of ten are more likely to be diagnosed with ASPD as adults.
A study conducted in 1987 revealed that problem behaviors such as habitual lying, shoplifting, and property damage are often precursors to a diagnosis of conduct disorder. Furthermore, researchers suggest that children who demonstrate a lack of empathy towards others’ pain may face an increased risk of developing ASPD in their late adolescence.
