Comorbidity and mixed anxiety-depressive disorder: clinical curiosity or pathophysiological need?

The paper reviews available epidemiological evidence for the existence of and the implications of comorbidity of anxiety and depressive disorders and mixed anxiety-depressive (MAD) disorders. Using epidemiolological evidence of prevalence and incidence and data relating to time-course of illness, risk factor and outcome, it is concluded: (1) that anxiety-depression comorbidity is quite frequent in epidemiological and clinical settings throughout the world; (2) this comorbidity is diagnosis-specific and is associated with increased vulnerabilities and risks as well as poorer outcome and marked disabilities; and (3) no such evidence was found for MAD disorders. Contrary to what was predicted, the prevalence of MAD disorders was quite low even when using the more recent criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. (4) Furthermore, there was quite a heterogeneous pattern in terms of risk, severity and outcome making it questionable whether this disorder, as currently defined, is a clinical entity. These findings are discussed in terms of two perspectives, the 'lumpers' with their dimensional view and the 'splitters' with their categorical view. It is concluded that although comorbidity of threshold anxiety and depressive disorders seems to be an important phenomenon, no such evidence is provided for MAD disorders.

Does urbanicity shift the population expression of psychosis?

Growing up in an urban area has been shown to be associated with an increased risk of psychotic disorder in later life. While it is commonly held that a only a tiny fraction of exposed individuals will develop schizophrenia, recent evidence suggests that expression of psychosis in exposed individuals may be much more common, albeit at attenuated levels. Findings are based on a population sample of 2548 adolescents and young adults aged originally 14-24 years, and followed up over almost 5 years up to ages 17-28 years. Trained psychologists assessed all these subjects with the core psychosis sections on delusions and hallucinations of the Munich-Composite International Diagnostic Interview. Growing up in an urban area was associated with an increased risk of expression of psychosis in the adolescents and young adults (adjusted OR 1.31, 95% CI 1.03-1.66). The proxy environmental risk factor that urbanicity represents may shift a relatively large section of the adolescent population along a continuum of expression of psychosis. Other causal influences may be required to make the transition to schizophrenia in adult life.

Parental depression and depression in offspring: evidence for familial characteristics and subtypes?

The objectives of this paper were twofold. First, to evaluate in a community sample the age of onset of major depression in adolescents and young adults with and without parental major depression. Second, to examine whether specific clinical characteristics of major depression in adolescents and young adults are associated with elevated rates of major depression among parents. Baseline and 4-year follow-up data were used from the Early Developmental Stages of Psychopathology Study (EDSP), a prospective-longitudinal community study of adolescents and young adults. Results are based on 470 subjects who completed the follow-up, for whom diagnostic information for both parents was available, and who reported at least one episode of major depression according to DSM-IV-criteria through second follow-up. Diagnostic assessment in respondents was accomplished by using the standardized Munich-Composite International Diagnostic Interview (M-CIDI). Information on major depression in parents was collected as family history information from the respondents, and additionally from M-CIDI diagnostic interviews with parents of the younger cohort. Both recurrence and impairment as clinical characteristics of major depression in adolescents and young adults were associated with elevated rates of major depression among parents. Age of onset as well as overall higher impairment as clinical characteristics of major depression in youth were associated with elevated rates of parental major depression in the univariate, but not in the multiple, analyses. Our findings suggest that clinical features of major depression may indicate familial subtypes of the disorder, most evident for recurrence and impairment.
