As mentioned above, it seems that there is a transactional relationship between substance use and conduct problems, such that aggressive behaviors increase substance use, which leads to increased aggressive behavior.Substance use in conduct disorder can lead to antisocial behavior in adulthood. Schizophrenia
Conduct disorder is a precursor to schizophrenia in a minority of cases, with about 40% of men and 31% of women with schizophrenia meeting criteria for childhood conduct disorder. Cause
While the cause of conduct disorder is complicated by an intricate interplay of biological and environmental factors, identifying underlying mechanisms is crucial for obtaining accurate assessment and implementing effective treatment. These mechanisms serve as the fundamental building blocks on which evidence-based treatments are developed. Despite the complexities, several domains have been implicated in the development of conduct disorder including cognitive variables, neurological factors, intraindividual factors, familial and peer influences, and wider contextual factors. These factors may also vary based on the age of onset, with different variables related to early (e.g., neurodevelopmental basis) and adolescent (e.g., social/peer relationships) onset. Risks
The development of conduct disorder is not immutable or predetermined. A number of interactive risk and protective factors exist that can influence and change outcomes, and in most cases conduct disorder develops due to an interaction and gradual accumulation of risk factors. In addition to the risk factors identified under cause, several other variables place youth at increased risk for developing the disorder, including child physical abuse, in-utero alcohol exposure, and maternal smoking during pregnancy.
It has since been marketed under more than 100 trade names, from Amepromat through Quivet to Zirpon.A December 1955 study of 101 patients at the Mississippi State Hospital in Whitfield, Rankin County, Mississippi, found meprobamate useful in the alleviation of "mental symptoms": 3% of patients made a complete recovery, 29% were greatly improved, 50% were somewhat better, while 18% realized little change. Self-destructive patients became cooperative and calmer, and experienced a resumption of logical thinking. In 50% of the cases, relaxation brought about more favorable sleep habits. Following the trial, hydrotherapy and all types of shock treatment were subsequently halted. Meprobamate was found to help in the treatment of alcoholics by 1956. By 1957, over 36 million prescriptions had been filled for meprobamate in the US alone, a billion pills had been manufactured, and it accounted for fully a third of all prescriptions written. Berger, clinical director of Wallace Laboratories, described it as a relaxant of the central nervous system, whereas other tranquilizers suppressed it. A University of Michigan study found that meprobamate affected driving skills. Though patients reported being able to relax more easily, meprobamate did not completely alleviate their tense feelings. The disclosures came at a special scientific meeting at the Barbizon Plaza Hotel in New York City, at which Aldous Huxley addressed an evening session.
