..The aims of this paper are twofold: (a) to explore seasonal patterns in a large, Danish Medical Birth Register, and (b) to explore models based on seasonal exposures and a non-linear exposure-risk relationship...

..If valid, Danes emigrating from Denmark carry a higher predisposition to develop schizophrenia compared to Danes living in Denmark...

....

..Urbanicity of place of birth and during upbringing has been shown to be related to the risk of schizophrenia. Few studies of urbanicity in relation to bipolar affective disorder exist...

..Some of the cause(s) responsible for the urban-rural differences in schizophrenia risk are rooted in families, but some might also be rooted in individuals...

..Though unknown, the causes of these urban-rural differences have been hypothesized to include, e.g., infections, diet, toxic exposures, social class, or an artefact due to selective migration...

..There have been conflicting reports on time trends in urban-rural differences in the incidence of schizophrenia. This study explored the potential time trends in these differences with regard to birth cohort and age at onset...

..The Danish Civil Registration System (CRS) was established in 1968, and all persons alive and living in Denmark were registered for administrative use...

..In this study, we aimed at quantifying the risk of neonatal death as a function of a baby's failure to fulfil its biologic growth potential across the whole distribution of birth weight...

..No studies have had sufficient size to estimate mortality in children with febrile seizures. We studied mortality after febrile seizures in a large population-based cohort of children in Denmark with up to 28 years of follow-up...

..We investigated the magnitude of the overlap between the clinical diagnoses of bipolar affective disorder, schizoaffective disorder, and schizophrenia over a 35-year period based on the entire Danish population...

..Febrile seizure is a benign condition for most children, but experiments in animals and neuroimaging studies in humans suggest that some febrile seizures may damage the hippocampus, a brain area of possible importance in schizophrenia...

..The risk was higher for those who had a family history of epilepsy, cerebral palsy, or low Apgar scores at 5 minutes...

..The aim was to assess how a history of mental disorders in either a first-degree family member or partner affects the risk of admission or outpatient contact with PPMD...

..A few studies have found that some men have symptoms of depression after becoming fathers, but these studies have not documented whether this exceeds the morbidity among men in general...

..The authors aimed to distinguish between these two measures of paternal age...

..The aim of this study was to examine the association between neonatal markers of selected prenatal infections and risk for bipolar disorder...

..The purpose of this study was to determine whether mothers infected with T. gondii have an elevated risk of schizophrenia or related disorders and whether the risk depends on IgG antibody level...

..Moreover, overall immigrants conferred a higher risk of psychiatric contact throughout the entire perinatal period...

..Several studies have implicated early infections, including maternal infection with herpes simplex virus 2 (HSV-2), as an environmental risk factor for schizophrenia...

..To our knowledge, no prior study has compared mothers and nonmothers to determine whether the risk of readmission differs between these 2 groups of women...

....

..Few studies have reported the age- and gender-specific incidence of schizophrenia in people aged up to 71 years, and no studies have reported the cumulative incidence of schizophrenia in people aged up to 71 years...

..In conclusion, short gestational age, low birth weight, and intrauterine growth restriction are associated with an increased risk of epilepsy...

..We examined whether discontinuing the use of thimerosal-containing vaccines in Denmark led to a decrease in the incidence of autism...

..In contemporary society, people change their place of residence frequently. However, large-scale population studies documenting the influence of frequent moves on mental health among children and adolescents are limited...
