Diagnostic procedures in ischaemic stroke patients with dementia. a population-based study

{Background Dementia is a frequent condition in stroke patients. Aims To investigate the effect of dementia on access to diagnostic procedures in ischaemic stroke patients. Methods All cases of ischaemic stroke from 2006 to 2010 were identified from the population-based Stroke Registry of Dijon, France. Patients' characteristics were recorded, as was the use of brain computed tomography scans, brain magnetic resonance imaging, electrocardiogram, echocardiography, and Doppler ultrasonography of the cervical arteries. Dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Logistic regression models were used to evaluate the associations between dementia and the use of the diagnostic procedures. Results Of the 907 patients recorded, 104 were excluded because of death and inability to test cognition. Among the remaining 803 patients, 149 (18.5%) had dementia. Almost all of the patients underwent a brain computed tomography scan and an electrocardiogram during their stay. In contrast, the use of both Doppler ultrasonography of the cervical arteries (79.2% versus 90.2%, P < 0.001), echocardiography (32.9% versus 43.6%
