The results of seven population-based studies were examined separately and pooled to obtain age- and sex-specific estimates of the prevalence of PD. An in-person screening instrument and diagnostic clinical examination were used to detect potential PD cases. The overall prevalence (per 100 population) in persons 65 years of age and older was 1.8, with an(More)
A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three replicate. Estimated effects sizes are small (coefficient of(More)
OBJECTIVE To evaluate prevalence, sociodemographic characteristics, and risk factors of restless legs syndrome (RLS) in a population-based survey of the elderly, using standard diagnostic criteria. BACKGROUND Population-based studies of RLS are rare and have not yet used standard definition criteria. METHODS The Memory and Morbidity in Augsburg Elderly(More)
BACKGROUND High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the(More)
One fundamental question about pulsars concerns the mechanism of their pulsed electromagnetic emission. Measuring the high-end region of a pulsar's spectrum would shed light on this question. By developing a new electronic trigger, we lowered the threshold of the Major Atmospheric gamma-ray Imaging Cherenkov (MAGIC) telescope to 25 giga-electron volts. In(More)
OBJECTIVE To find sequence variants that associate with the risk for ischemic stroke (IS), we performed a genome-wide association study. METHODS We genotyped 1,661 Icelandic IS patients and 10,815 control subjects using the Infinium HumanHap300 chip (Illumina, San Diego, CA). A total of 310,881 single nucleotide polymorphisms (SNPs) were tested for(More)
Restless legs syndrome (RLS) is a sensorimotor disorder with an age-dependent prevalence of up to 10% in the general population above 65 years of age. Affected individuals suffer from uncomfortable sensations and an urge to move in the lower limbs that occurs mainly in resting situations during the evening or at night. Moving the legs or walking leads to an(More)
BACKGROUND AND PURPOSE There is little information about early outcome after intravenous application of tissue-type plasminogen activator (tPA) for stroke patients treated in community-based settings. We investigated the association between tPA therapy and in-hospital mortality in a pooled analysis of German stroke registers. METHODS Ischemic stroke(More)
Very few genetic variants have been associated with depression and neuroticism, likely because of limitations on sample size in previous studies. Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotypes:(More)
BACKGROUND AND PURPOSE Ischemic stroke is a multifactorial disease with a strong genetic component. Pathways, including lipid metabolism, systemic chronic inflammation, coagulation, blood pressure regulation, and cellular adhesion, have been implicated in stroke pathophysiology, and candidate gene polymorphisms in these pathways have been proposed as(More)
