- BACKGROUND AND PURPOSE: Frontostriatal circuits involving the caudate nucleus have been implicated in frontotemporal lobar degeneration (FTLD). We assessed caudate nucleus volumetrics in FTLD and subtypes: frontotemporal dementia (FTD, n = 12), semantic dementia (SD, n = 13), and progressive nonfluent aphasia (PNFA, n = 9) in comparison with healthy controls (n = 27) and subjects with Alzheimer disease (AD, n = 19). MATERIALS AND METHODS: Diagnoses were based on accepted clinical criteria. Manual volume measurement of the head and body of the caudate, excluding the tail, was conducted on T1-weighted brain MR imaging scans, using a published protocol, by a single analyst blinded to the diagnosis. RESULTS: Paired t tests (P < .05) showed that the right caudate nucleus volume was significantly larger than the left in controls and PNFA. No hemispheric asymmetry was found in AD, ETD, and SD. Across the groups, there was a positive partial correlation between the left caudate nucleus volume and Mini-Mental State Examination (MMSE) scores (r = 0.393, n = 76, P = .001) with higher left caudate volumes associated with higher MMSE scores. Multivariate analysis of covariance was used to assess the statistical significance between the subject groups (AD, ETD, SD, PNFA, and controls) as independent variables and raw right/left caudate volumes at the within-subject level (covariates: age and intracranial volume; P < .05). Control volume was largest, followed by AD (93% of control volume), SD (92%), PNFA (79%), and ETD (75%). CONCLUSIONS: Volume of the head and body of the caudate nucleus differs in subtypes of FTLD, due to differential frontostriatal dysfunction in subtypes being reflected in structural change in the caudate, and is correlated with cognition

- DESIGN: A population-based study of pre-adoption, arrival and post-adoption health.AIM: To report prenatal and postnatal background factors, morbidity, growth and development in adoptees from Eastern Europe.SUBJECTS AND METHODS: All 99 children born in Eastern Europe between 1990 and 1995 and adopted to western Sweden during 1993-1997 were invited to participate in the study. Altogether, 76 (77%) participated. Medical records from the birth countries, from the examination at arrival and from medical reports made during a mean post-adoption period of 5 years were evaluated.RESULTS: Low birth weight (< or = 2500 g) occurred in 48%. Congenital malformations were found in 22%. The biological mothers of 33% of the children had been considered alcoholics, and 16% of the children's mothers had been diagnosed with a psychiatric disability. A high incidence of infectious diseases, neurodevelopment disorders and growth retardation had been noted during the pre-adoption period. Upon arrival in Sweden 75% were diagnosed with a medical condition, most often an infection. After a 5-year post-adoption period, small head circumference was associated with alcohol exposure during pregnancy and 46% had at least one neurodevelopment or behavioural disorder.CONCLUSION: Adverse prenatal and perinatal factors, congenital malformations and post-adoption neurodevelopment disorders were common. Adoptees and adopters have complex needs for health support and information.
