These mice specifically exhibit working memory deficits attributable to frontal-subcortical circuit damage without apparent gray matter changes, indicating similarities with subcortical ischemic vascular dementia. However, as subcortical ischemic vascular dementia progresses over time, the longer-term effects that characterize the mouse model are not known.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods\u2014<\/jats:italic>\n            <\/jats:bold>\n            Comprehensive behavioral test batteries and histological examinations were performed in mice subjected to BCAS for up to 8 months. Laser speckle flowmetry and\n            <jats:sup>18<\/jats:sup>\n            F-fluorodeoxyglucose positron emission tomography were performed to assess cerebral blood flow and metabolism at several time points.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            At 2 hours after BCAS, cerebral blood flow in the cerebral cortex temporarily decreased to as much as 60% to 70% of the control value but gradually recovered to &gt;80% at 1 to 3 months. At 5 to 6 months after BCAS, reference and working memory were impaired as demonstrated by the Barnes and radial arm maze tests, respectively. Furthermore,\n            <jats:sup>18<\/jats:sup>\n            F-fluorodeoxyglucose positron emission tomography demonstrated that hippocampal glucose utilization was impaired at 6 months after BCAS. Consistent with these behavioral and metabolic abnormalities, histological analyses demonstrated hippocampal atrophy with pyknotic and apoptotic cells at 8 months after BCAS.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            These results suggest that the longer-term BCAS model replicates advanced stages of subcortical ischemic vascular dementia when hippocampal neuronal loss becomes significant.\n          <\/jats:p>","DOI":"10.1161\/strokeaha.110.581686","type":"journal-article","created":{"date-parts":[[2010,5,7]],"date-time":"2010-05-07T02:20:35Z","timestamp":1273198835000},"page":"1278-1284","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":193,"title":["A Mouse Model Characterizing Features of Vascular Dementia With Hippocampal Atrophy"],"prefix":"10.1161","volume":"41","author":[{"given":"Keiko","family":"Nishio","sequence":"first","affiliation":[{"name":"From Department of Neurology (K.N., M.I., T.M., Y.F., H.I., R.T., H.T.), Graduate School of Medicine, Kyoto University, Sakyo-ku, Kyoto, Japan;
