In a large unselected community-dwelling population, we examined the frequency of clinical left- and right-sided strokes and transient ischemic attacks (TIAs) and compared it with the frequency of left- and right-sided infarcts on MRI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods\u2014<\/jats:title>\n                    <jats:p>This study was conducted within the population-based Rotterdam Study. Between 1990 and 2012, 13 894 participants were followed up for first-ever stroke and TIA. MRI scans were performed within a random subgroup of 5081 persons and were rated for the presence of supratentorial cortical and lacunar infarcts. We compared frequencies of left- and right-sided strokes, TIAs, or MRI infarcts using binomial and Fisher exact tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results\u2014<\/jats:title>\n                    <jats:p>After a mean follow-up of 9.6 (\u00b16.0) years, 1252 patients had a stroke, of which 704 were ischemic, and 799 participants had a TIA. Within the subgroup with MRI, we identified 673 infarcts. Ischemic strokes were more frequently left-sided (57.7%; 95% confidence interval, 53.7\u201361.6) than right-sided, similar to TIAs (57.8% left-sided; 53.4\u201362.3). In contrast, we found no left-right difference in distribution of infarcts on MRI (51.9% left-sided; 48.1\u201355.6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions\u2014<\/jats:title>\n                    <jats:p>Clinical ischemic strokes and TIAs are more frequently left-sided than right-sided, whereas this difference is not present for infarcts on MRI. This suggests that left-sided strokes and TIAs are more easily recognized. Consequently, there should be more attention for symptoms of right-sided strokes and TIAs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/strokeaha.114.007385","type":"journal-article","created":{"date-parts":[[2014,12,10]],"date-time":"2014-12-10T00:23:24Z","timestamp":1418171004000},"page":"252-254","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":61,"title":["Left-Sided Strokes Are More Often Recognized Than Right-Sided Strokes"],"prefix":"10.1161","volume":"46","author":[{"given":"Marileen L.P.","family":"Portegies","sequence":"first","affiliation":[{"name":"From the Department of Epidemiology (M.L.P.P., M.S., A.H., M.W.V., M.A.I.), Neurology (M.L.P.P., P.J.K., M.A.I.), Biomedical Engineering (M.S.), and Radiology (M.S., M.W.V.), Erasmus MC University Medical Center, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Selwaness","sequence":"additional","affiliation":[{"name":"From the Department of Epidemiology (M.L.P.P., M.S., A.H., M.W.V., M.A.I.), Neurology (M.L.P.P., P.J.K., M.A.I.), Biomedical Engineering (M.S.), and Radiology (M.S., M.W.V.), Erasmus MC University Medical Center, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert","family":"Hofman","sequence":"additional","affiliation":[{"name":"From the Department of Epidemiology (M.L.P.P., M.S., A.H., M.W.V., M.A.I.), Neurology (M.L.P.P., P.J.K., M.A.I.), Biomedical Engineering (M.S.), and Radiology (M.S., M.W.V.), Erasmus MC University Medical Center, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J.","family":"Koudstaal","sequence":"additional","affiliation":[{"name":"From the Department of Epidemiology (M.L.P.P., M.S., A.H., M.W.V., M.A.I.), Neurology (M.L.P.P., P.J.K., M.A.I.), Biomedical Engineering (M.S.), and Radiology (M.S., M.W.V.), Erasmus MC University Medical Center, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meike W.","family":"Vernooij","sequence":"additional","affiliation":[{"name":"From the Department of Epidemiology (M.L.P.P., M.S., A.H., M.W.V., M.A.I.), Neurology (M.L.P.P., P.J.K., M.A.I.), Biomedical Engineering (M.S.), and Radiology (M.S., M.W.V.), Erasmus MC University Medical Center, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
