These behaviors are often referred to as "antisocial

First onset of mental disorders usually occurs in childhood or adolescence, although treatment typically does not occur until a number of years later.
The purpose of this paper is to review recent evidence from epidemiological surveys on the age of onset AOO distributions of commonly occurring mental disorders. Although AOO is one of the least commonly studied aspects of descriptive epidemiology, it is important for reasons described below. These data have several important implications for clinical practice and research that are discussed in the second half of the review.
The dearth of information on AOO of mental disorders is presumably due to reluctance on the part of epidemiologists to rely on the retrospective reports obtained in general population surveys that, as a practical matter, must be used to generate the survival distributions needed to study AOO. Two theoretical alternatives exist to relying on these retrospective reports, literature review on conduct disorder, although neither of the two is broadly feasible. The same approach would not be nearly as useful, though, for less severely impairing disorders, as many people with such disorders never come to clinical attention.
Comparable studies of mental disorders do not exist. ukthe data collection waves are not sufficient frequent and the assessment mental disorder interval incidence not sufficiently central to generate accurate prospective estimates of incidence.
Prospective birth cohort studies in schizophrenia that cover the whole age range of risk for the onset of the disorder are sparse e. An examination of AOO distributions is important for at least two reasons.
One is that information on AOO allows us to distinguish between lifetime prevalence the proportion of the population who had a disorder at some time in their life up to their age at interview and projected lifetime risk the estimated proportion of the population who will have the disorder by the end of their life. Lifetime risk cannot be estimated directly from community surveys because respondents differ in age and, therefore, number of years at risk. In the absence of AOO information, we would have no way to know the appropriate age range to target preventive interventions.
A related issue is that early AOO is often found to be associated with greater disorder severity [ 14 ], persistence [ 15 ], and lack of treatment response [ 16 ]. Based on these associations, AOO information can be useful in making projections of aggregate illness course associated with primary and secondary disorders. As the main focus of the following review is on the WMH surveys, we present a brief overview of WMH literature review on conduct disorder. The WMH Survey Initiative consists of coordinated population literature review on conduct disorder in 28 countries [ 17 ].
The main aim is to provide estimate of the prevalence, distribution, societal burden, and patterns of treatment of mental disorders to literature review on conduct disorder policy makers for planning purposes. The WMH interview schedule and all other study materials were translated using standardized WHO protocols. Consistent interviewer training and quality control procedures were used in all surveys.
The informed consent was obtained in each country using procedures approved by the Institutional Review Boards of the organizations coordinating the survey in the country. The surveys in most of these countries were nationally representative the exceptions being China, Japan, and Nigeria, which were regionally representative. Seven of the countries are classified by the World Bank as less developed China, Colombia, Lebanon, Mexico, Nigeria, South Africa, Ukrainewhile the others are classified as developed [ 18 ].
A total of 85, interviews were completed in these 16 countries, with samples ranging from in the Netherlands to 12, in New Zealand. The weighted average response rate was More details on WMH samples, designs, and field procedures are presented at www.
The WMH diagnostic interview was the WHO Composite Diagnostic Interview CIDI Version 3. Not all disorders were assessed in all countries. Research carried out in conjunction with the landmark Epidemiological Catchment Area ECA [ 23 ]. Study found that retrospective AOO reports often generate implausible response patterns, indicating the existence of retrospective recall bias [ 24 ]. Special procedures developed by survey methodologists to minimize this bias were used in the WMH surveys both to decrease recall failure involving the lifetime occurrence of disorders [ 19 ] and to decrease imprecision in dating the AOO of reported disorders [ 25 ].
Experimental research has shown that this question sequence yields responses with a much more plausible AOO distribution than standard AOO questions [ 25 ]. Fully half of all lifetime IED begins in childhood or adolescence. Mood disorder AOO curves show consistently low prevalence until the early teens followed by a roughly linear increase through late middle age and a declining increase thereafter.
The median AOO of mood disorders has a very wide range across countries 25—45 and an even wider IQR 17— The AOO distributions of substance use disorders, finally, are quite consistent across the WMH countries in that few onsets occur prior to the mid teens and cumulative increase in onset is rapid in adolescence and early adulthood.
Psychotic disorders rarely occur before age 14, but show a marked increase in prevalence between at ages 15—17 [ 35 ]. Schizophrenia usually bens in the age range 15— A good example of such a system can be found at the Early Psychosis Prevention and Intervention Centre EPPIC in Melbourne, Australia.
Between andindividuals were registered at EPPIC with a first episode of psychosis, literature review on conduct disorder. The median age of initial presentation in this cohort was 22 with an IQR of literature review on conduct disorder Similar results were found in the North Finland Birth Cohort, where median AOO and IQR for schizophrenia were 23 and 19—27 [ 8 ], and in the British birth cohort median AOO for schizophrenia 22 [ 7 ].
As noted in the introduction, one important reason for estimating AOO distributions is to obtain data on projected lifetime risk. This means that literature review on conduct disorder people in the populations of these countries are likely to develop a first mental disorder at some time in the future for every ten people who already had a disorder.
Although innovative strategies were used to minimize the latter problem [ 19 ], it is unlikely that they were completely successful. AOO might have been recalled incorrectly as well literature review on conduct disorder 24 ] despite the WMH surveys using a novel probing strategy to reduce bias in AOO reports. Estimates of psychosis AOO were limited by their being based on incident treatment. The AOO results are further limited by focusing on syndrome onset, ignoring any prodrome at an earlier age.
Childhood behavioral inhibition is known to occur prior to the onset of many cases of panic disorder and depression [ 42 ], literature review on conduct disorder. Epidemiological analysis of these early indicators of incipient disorder would almost certainly lead to much earlier estimates literature review on conduct disorder AOO than those reported here.
Within the context of these limitations, the AOO distributions reported here are consistent with those in previous epidemiological surveys [ 43literature review on conduct disorder, 44 ]. We know of no research prior to the WMH surveys that examined AOO distributions of PTSD, but one would expect these to be quite variable due to trauma exposure occurring throughout the life course.
No previous research has examined the temporal concentration of AOO or highlighted the concentration of onset ages for most disorders in a very narrow time span. These are opposite the patterns found for chronic physical disorders, where conditional risk increases with age and the upper bound of the IQR is in late middle age or old age [ 47 ].
Investigations of initial contact with the treatment system based on data collected in a number of literature review on conduct disorder epidemiological surveys [ 48 ] have consistently found that many people wait more than a decade after first onset of a mental disorder before seeking treatment.
These people often present with highly comorbid conditions that might have been easier to treat if they had sought treatment earlier in the course of illness.
The results reported here show clearly that first onset of mental disorders usually occurs in childhood or adolescence.
