The global endemic of cardiovascular diseases calls for improved risk assessment and treatment. Here, we describe an association between myocardial infarction (MI) and a common sequence variant on chromosome 9p21. This study included a total of 4587 cases and 12,767 controls. The identified variant, adjacent to the tumor suppressor genes CDKN2A and CDKN2B,(More)
We conducted a genome-wide association study for type 2 diabetes (T2D) in Icelandic cases and controls, and we found that a previously described variant in the transcription factor 7-like 2 gene (TCF7L2) gene conferred the most significant risk. In addition to confirming two recently identified risk variants, we identified a variant in the CDKAL1 gene that(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)
The aim of this study was to test predictions based on Grossberg's theories of overarousal in neural networks as related to schizophrenic symptomatology. We predicted that symptoms of blunted affect and volition would be associated with reduced P300 amplitude, while impaired attention and short-term memory and symptoms of disorganization would be associated(More)
OBJECTIVES This study was undertaken to estimate the cognitive abilities in an elderly population in rural areas in Iceland and to get an idea of the prevalence of dementia. By examining inhabitants in two different areas it was further possible to detect any possible difference in these areas. MATERIAL AND METHODS All persons aged 70 and over, living(More)
To investigate the nature and rate of cognitive decline in dementia of the Alzheimer's type (DAT), 44 patients with probable or possible DAT (mean age 73.9, range 59-87 years) were given a comprehensive neuropsychological assessment. Twenty-five patients were retested 6 months later, and 11 were tested for the third time another 6 months later. Some tests(More)
