- Background: Although many studies have documented deficits in general motor functioning in children with fetal alcohol syndrome (FAS), few have employed detailed measurements to explore the specific nature of such disabilities. This pilot study explores whether three-dimensional (3D) kinematic analysis may generate increased knowledge of the effect of intrauterine alcohol exposure on motor control processes by detecting atypical upper-limb movement pattern specificity in children with FAS relative to typically developing (TD) children. Methods: Left and right arm and head movements during a sequential unimanual goal-directed precision task in a sample of children with FAS and in TD children were registered by an optoelectronic tracking system (ProReflex, Qualisys Inc.). Results: Children with FAS demonstrated evidently poorer task performance compared with TD children. Additionally, analyses of arm movement kinematics revealed atypical spatio-temporal organization in the children with FAS. In general, they exhibited longer arm movement trajectories at both the proximal and distal level, faster velocities at the proximal level but slower at the distal level, and more segmented distal movements. Children with FAS also showed atypically augmented and fast head movements during the task performance. Conclusions: Findings indicate neuromotor deficits and developmental delay in goaldirected arm movements because of prenatal alcohol exposure. It is suggested that 3D kinematic analysis is a valid technique for furthering the understanding of motor control processes in children with FAS/fetal alcohol spectrum disorders. A combination with relevant neuroimaging techniques in future studies would enable a more clear-cut interpretation of how atypical movement patterns relate to underlying brain abnormalities.

- © 2017 EAN Background and purpose: Visuospatial inattention (VSI) and language impairment (LI) are often present early after stroke and associations with an unfavorable short-term functional outcome have been reported. The purpose of this study was to investigate whether a screening of VSI and LI as indicators of cortical symptoms early after stroke could predict long-term functional outcomes. Methods: A consecutive cohort of 375 patients with ischemic stroke was assessed for the occurrence of VSI at a median of 7 days after admission (interquartile range, 1–5 days) using the Star Cancellation Test and for LI (within the first 7 days) with the language item in the Scandinavian Stroke Scale. Seven years later, functional outcomes were assessed by the modified Rankin scale and Frenchay Activities Index in 235 survivors without recurrent stroke. Relationships between baseline predictors and functional outcome at 7 years were analyzed with bivariate correlations and multiple categorical regressions with optimal scaling. Results: The regression model significantly explained variance in the modified Rankin scale (R 2 = 0.435, P < 0.001) and identified VSI (P = 0.001) and neurological deficits (P < 0.001; Scandinavian Stroke Scale score without the language item) as the significant independent predictors. The model for Frenchay Activities Index was also significant (R 2 = 0.269, P < 0.001) with VSI (P = 0.035) and neurological deficits (P < 0.001) as significant independent predictors. Conclusions: Visuospatial inattention at acute stroke has an independent impact on long-term functional outcomes. Early recognition may enable targeted rehabilitative interventions.

- BACKGROUND AND PURPOSE: Studies on cognitive decline in myotonic dystrophy type 1 (DM1) are characterized by conflicting results. The purpose of the present study was to analyse possible decline in classical/adult onset DM1 at a 5-year follow-up and to explore the correlation with disease-related and demographic factors. METHODS: Patients with DM1 (n = 37) were examined with a comprehensive neuropsychological test battery yielding measures on memory, attention, verbal, visuospatial and executive functions. Assessment of muscle impairment and CTG repeat expansion size was performed. RESULTS: A majority of the participants (65%) performed worse at follow-up. Compared to normative data, patients scored significantly worse on tests measuring memory, attention, visuospatial construction and verbal ability. Neither CTG repeat size nor muscle impairment related to cognitive decline. However, age at onset and disease duration were correlated with the number of tests in which performance was below 1 SD at both baseline and follow-up examination. CONCLUSIONS: Measurements show that classical/adult onset DM1 is characterized by cognitive decline. Both earlier onset and longer duration of the disease are indicative of more cognitive deficits.

- This study assessed the cost to society of multiple sclerosis (MS) in Sweden in 1998. The cost-of-illness method, based on the human capital theory, was used as the theoretical framework. The study used a cross-sectional approach, in which resource utilization data and quality-of-life data (utilities) were collected at a single time point. The total cost of MS was estimated at 4868 MSEK, or 586 MEUR, giving an annual cost of 442 500 SEK, or 53 250 EUR, per patient (1USD = 9.73 SEK, 1 EUR = 8.31 SEK, as of 21 September 2000). Direct costs accounted for about 67% of total cost, and they were dominated by the cost of personal assistants and drugs. Indirect costs (loss of production) accounted for about 33% of total costs. To these economic costs, intangible costs of 2702 MSEK (325 MEUR) should be added as well. Direct, indirect and informal care costs all rose significantly with increased disability and were higher during a relapse. Quality of life declined substantially with increased disability and was lower during a relapse. Multiple sclerosis was found to be associated with much higher costs to society than has been ascertained by former studies. The study also revealed a strong correlation between severity of the disease and quality of life. These results are crucial for further studies on the cost-effectiveness of new treatments aimed at preventing relapses and reducing progression of the disease.

- BACKGROUND AND PURPOSE: In 2005, we presented for the first time overall estimates of annual costs for brain disorders (mental and neurologic disorders) in Europe. This new report presents updated, more accurate, and comprehensive 2010 estimates for 30 European countries.METHODS: One-year prevalence and annual cost per person of 19 major groups of disorders are based on 'best estimates' derived from systematic literature reviews by panels of experts in epidemiology and health economics. Our cost estimation model was populated with national statistics from Eurostat to adjust to 2010 values, converting all local currencies to Euros (€), imputing cost for countries where no data were available, and aggregating country estimates to purchasing power parity-adjusted estimates of the total cost of brain disorders in Europe in 2010.RESULTS: Total European 2010 cost of brain disorders was €798 billion, of which direct health care cost 37%, direct non-medical cost 23%, and indirect cost 40%. Average cost per inhabitant was €5.550. The European average cost per person with a disorder of the brain ranged between €285 for headache and €30 000 for neuromuscular disorders. Total annual cost per disorder (in billion € 2010) was as follows: addiction 65.7; anxiety disorders 74.4; brain tumor 5.2; child/adolescent disorders 21.3; dementia 105.2; eating disorders 0.8; epilepsy 13.8; headache 43.5; mental retardation 43.3; mood disorders 113.4; multiple sclerosis 14.6; neuromuscular disorders 7.7; Parkinson's disease 13.9; personality disorders 27.3; psychotic disorders 93.9; sleep disorders 35.4; somatoform disorder 21.2; stroke 64.1; and traumatic brain injury 33.0.CONCLUSION: Our cost model revealed that brain disorders overall are much more costly than previously estimated constituting a major health economic challenge for Europe. Our estimate should be regarded as conservative because many disorders or cost items could not be included because of lack of data.

- AIM: The aim of the study was to assess the cellular and structural properties of skeletal muscle in restless legs syndrome (RLS).METHOD: Twenty patients and 16 controls were included. Aerobic performance was assessed using a submaximal test. On muscle biopsies taken from the tibialis anterior, fiber distribution and fiber area were analyzed together with parameters surveying the microvascularization, especially the tortuosity, which is expressed as a percent of muscle fiber perimeter in contact with the wall of the microvessel, length of capillary/perimeter of fiber (LC/PF) index.RESULTS: The RLS group had significantly lower predicted maximal oxygen uptake (p = 0.01) and significantly higher LC/PF index (p = 0.01) compared to the controls.CONCLUSION: The higher capillary tortuosity in RLS patients indicates the occurrence of significant remodeling in capillary geometry in RLS.
