Research has investigated the comorbidity between autism spectrum disorder (ASD) and conduct disorder. Due to research studies, it has been concluded that comorbidity between ASD and conduct disorders are frequent. If these two disorders are presentable among one individual, the effects typically begin in early infancy and will continue through life. It is seemingly stated that if one has ASD and conduct disorder, ASD is usually the precursor. This means that if both of these occur in someone, the effects of autism will be the effector that leads to the person to develop conduct disorder as ASD does not follow conduct disorder.
