People with ASPD are also more likely to commit homicides and other crimes. Those who are imprisoned longer often see higher rates of improvement with symptoms of ASPD than others who have been imprisoned for a shorter amount of time.According to one study, aggressive tendencies show in about 72% of all male patients diagnosed with ASPD. About 29% of the men studied with ASPD also showed a prevalence of pre-meditated aggression. Based on the evidence in the study, the researchers concluded that aggression in patients with ASPD is mostly impulsive, though there are some long-term evidences of pre-meditated aggressions. It often occurs that those with higher psychopathic traits will exhibit the pre-meditated aggressions to those around them. Over the course of a patients life with ASPD, he or she can exhibit this aggressive behavior and harm those close to him or her. Additionally, many people (especially adults) who have been diagnosed with ASPD become burdens to their close relatives, peers, and caretakers. Harvard Medical School recommends that time and resources be spent treating victims who have been affected by someone with ASPD, because the patient with ASPD may not respond to the administered therapies. In fact, a patient with ASPD may only accept treatment when ordered by a court, which will make their course of treatment difficult and severe. Because of the challenges in treatment, the patients family and close friends must take an active role in decisions about therapies that are offered to the patient.
Studies have found that people with ASPD have difficulty understanding others emotions and mental states. It also may be possible that people with ASPD do not lack empathy but are less inclined to use it. Comorbidity
ASPD commonly coexists with the following conditions:

When combined with alcoholism, people may show frontal function deficits on neuropsychological tests greater than those associated with each condition. Alcohol use disorder is likely caused by lack of impulse and behavioral control exhibited by antisocial personality disorder patients. The rates of ASPD tends to register around 40–50% in male alcohol and opiate addicts. However, it is important to remember this is not a causal relationship, but rather a plausible consequence of cognitive deficits as a result of ASPD. Causes
Personality disorders are seen to be caused by a combination and interaction of genetic and environmental influences. Genetically, it is the intrinsic temperamental tendencies as determined by their genetically influenced physiology, and environmentally, it is the social and cultural experiences of a person in childhood and adolescence encompassing their family dynamics, peer influences, and social values. People with an antisocial or alcoholic parent are considered to be at higher risk. Fire-setting, and cruelty to animals during childhood are also linked to the development of antisocial personality. The condition is more common in males than in females, and among incarcerated populations. Genetic
Research into genetic associations in antisocial personality disorder suggests that ASPD has some or even a strong genetic basis. Prevalence of ASPD is higher in people related to someone with the disorder.
