Although it is being successfully implemented for exploration of the genome, discovery science has eluded the functional neuroimaging community. The core challenge remains the development of common paradigms for interrogating the myriad functional systems in the brain without the constraints of a priori hypotheses. Resting-state functional MRI (R-fMRI)(More)
Baseline activity of resting state brain networks (RSN) in a resting subject has become one of the fastest growing research topics in neuroimaging. It has been shown that up to 12 RSNs can be differentiated using an independent component analysis (ICA) of the blood oxygen level dependent (BOLD) resting state data. In this study, we investigate how many RSN(More)
We investigated the strength of evidence for association of the 5-HTTLPR polymorphism and the personality trait of Harm Avoidance. We used new primary data from a large sample of adults drawn from the Finnish population. We also applied meta-analytic techniques to synthesize existing published data. The large number of studies of the 5-HTTLPR polymorphism(More)
Delayed childhood development may precede adult psychoses. We tested this hypothesis in a large, general population birth cohort (n=12058) followed to age 31 years. The ages at which individuals learned to stand, walk, speak, and became potty-trained (bowel control) and dry (bladder control), were recorded at a 1-year examination. Psychiatric outcome was(More)
BACKGROUND Childhood neuromotor dysfunction is a risk factor for schizophrenia, a disorder in which cognitive deficits are prominent. The relationship between early neurodevelopment and adult cognition in schizophrenia remains unclear. METHODS We examined the associations between infant motor development and adult cognitive functions in schizophrenia (n =(More)
Objective: Our primary aims were (a) to identify the proportion of individuals with schizophrenia and related psy-choses who met recovery criteria based on both clinical and social domains and (b) to examine if recovery was associated with factors such as gender, economic index of sites, and selected design features of the study. We also examined if the(More)
Simple screening questionnaires for major psychiatric disorders are needed for epidemiological research and clinical work. We describe the characteristics of the Hopkins Symptom Checklist-25 (HSCL-25) as a screening instrument in a two-phase epidemiological survey using the Structured Clinical Interview for DSM-III-R (SCID) as a diagnostic tool. The(More)
BACKGROUND The relationship between the age of reaching infant developmental milestones and later intellectual function within the normal population remains unresolved. We hypothesised that the age of learning to stand in infancy would be associated with adult executive function and that the association would be apparent throughout the range of abilities,(More)
BACKGROUND The diagnosis of schizophrenia by clinicians is not always accurate in terms of operational diagnostic criteria despite the fact that these diagnoses form the basis of case registers and routine statistics. This poses a challenge to psychiatric research. We studied the reasons for diagnostic discordance between clinicians and researchers. (More)
