Confirming unexpressed genotypes for schizophrenia: risks in the offspring of Fischer's Danish identical and fraternal discordant twins

TL;DR: The results suggest that discordance in identical twins may primarily be explained by the capacity of a schizophrenic genotype or diathesis to be unexpressed unless it is released by some kinds of environmental, including nonfamilial, stressors.
Journal ArticleDOI

A comprehensive nationwide study of the incidence rate and lifetime risk for treated mental disorders.

TL;DR: This nationwide study provides a first comprehensive assessment of the lifetime risks for treated mental disorders and the distinct signatures of the different mental disorders with respect to sex and age have important implications for service planning and etiologic research.
Journal ArticleDOI

Severe mental disorders in offspring with 2 psychiatrically ill parents.

TL;DR: The effects of double predispositions on morbid risk in the offspring of parents both with schizophrenia or both with bipolar disorder are calculated to support evolving assumptions about genetic overlap for traditional categories.
Journal ArticleDOI

A cross-national epidemiological study of mania.

TL;DR: An epidemiological study of the first admission rate for mania was carried out in London and Aarhus to conduct a retrospective study of case notes covering several years, and a screening procedure was used for the prospective collection of new cases over the course of one year.
Journal ArticleDOI
