These deficits also occur in general-population samples of people with antisocial traits and in children with the precursors to antisocial personality disorder.People that exhibit antisocial behavior tend to demonstrate decreased activity in the prefrontal cortex. The association is more apparent in functional neuroimaging as opposed to structural neuroimaging. The prefrontal cortex is involved in many executive functions, including behavior inhibitions, planning ahead, determining consequences of action, and differentiating between right and wrong. However, some investigators have questioned whether the reduced volume in prefrontal regions is associated with antisocial personality disorder, or whether they result from co-morbid disorders, such as substance use disorder or childhood maltreatment. Moreover, it remains an open question whether the relationship is causal, i.e., whether the anatomical abnormality causes the psychological and behavioral abnormality, or vice versa.Cavum septi pellucidi (CSP) is a marker for limbic neural maldevelopment, and its presence has been loosely associated with certain mental disorders, such as schizophrenia and post-traumatic stress disorder. One study found that those with CSP had significantly higher levels of antisocial personality, psychopathy, arrests and convictions compared with controls. Environmental
Family environment
Many studies suggest that the social and home environment has contributed to the development of antisocial behavior. The parents of these children have been shown to display antisocial behavior, which could be adopted by their children.
Assessment
Assessment seeks to understand an individual by integrating information from multiple sources such as clinical interviews; medical exams and physiological measures; standardized psychometric tests and questionnaires; structured diagnostic interviews; review of records; and collateral interviews. Interviews
Psychologists, psychiatrists, and other mental health professionals conduct clinical interviews to ascertain the nature of a patient or clients difficulties, including any signs or symptoms of illness the person might exhibit. Clinical interviews are "unstructured" in the sense that each clinician develops a particular approach to asking questions, without necessarily following a predefined format. Structured (or semi-structured) interviews prescribe the questions, their order of presentation, "probes" (queries) if a patients response is not clear or specific enough, and a method to rate the frequency and intensity of symptoms.

Treatment
Treatment of suicidal ideation can be problematic due to the fact that several medications have actually been linked to increasing or causing suicidal ideation in patients. Therefore, several alternative means of treating suicidal ideation are often used. The main treatments include: therapy, hospitalization, outpatient treatment, and medication or other modalities. Therapy
In psychotherapy a person explores the issues that make them feel suicidal and learns skills to help manage emotions more effectively. Hospitalization
Hospitalization allows the patient to be in a secure, supervised environment to prevent the suicidal ideation from turning into suicide attempts. In most cases, individuals have the freedom to choose which treatment they see fit for themselves.
