This article describes a standardized administration and scoring procedure for the widely used Corsi Block-Tapping Task, designed to assess the visual memory span. This method was applied in a group of healthy participants (n = 70) and a group of patients with cerebral lesions (n = 70), that were categorized on the basis of lesion location (left or right(More)
BACKGROUND AND PURPOSE Information about the long-term prognosis of young adults with ischemic stroke is limited. Therefore, we performed a follow-up assessment of 296 patients with ischemic stroke who are enrolled in the Iowa Registry of Stroke in Young Adults. We studied young adults (age, 15 to 45 years) who were referred to a tertiary medical center for(More)
BACKGROUND AND PURPOSE Diffusion-weighted MRI (DWI) is highly sensitive in detecting early cerebral ischemic changes in acute stroke patients. In this study we compared the sensitivity of DWI with that of conventional MRI techniques. Furthermore, we investigated the prognostic value of the volume of ischemic lesions on DWI scans and of the apparent(More)
OBJECTIVE To examine the relation between depressive symptoms and specific cognitive functions in patients with a recent stroke and to examine associations with lesion characteristics. METHODS We studied 126 of 183 consecutive patients within 3 weeks after a first-ever symptomatic stroke (mean interval, 8.3+/-4.3 days). Presence and severity of depressive(More)
When reaching towards a visual stimulus, spatial information about the target must be transformed into an appropriate motor command. Visual information is coded initially in retinotopic coordinates, while the reaching movement ultimately requires the specification of the target position in limb-centred coordinates. It is well established that the posterior(More)
Patients with left-sided neglect frequently show repetitive behaviour on the ipsilesional side, such as re-markings on cancellation tasks or extensive elaboration on drawings. It is unclear whether these perseverative responses occur as a symptom of hemi-neglect or inattention in general, and/or whether they are related to anatomical brain correlates such(More)
OBJECTIVES To describe the likely causes of ischemic stroke in a population of young adults and to report the influence of strict algorithms on the diagnosis of the likely cause of stroke in this cohort. DESIGN Between July 1, 1977, and January 1, 1993, we registered 329 young adults with ischemic stroke in our registry. Diagnostic studies were selected(More)
BACKGROUND Determinants of survival and of risk of vascular events after transient ischaemic attack (TIA) or minor ischaemic stroke are not well defined in the long term. We aimed to restudy these risks in a prospective cohort of patients after TIA or minor ischaemic stroke (Rankin grade< or =3), after 10 years or more. METHODS We assessed the survival(More)
To test interphysician agreement on the diagnosis of subtype of ischemic stroke, we sent subtype definitions and 18 case summaries (clinical features and pertinent laboratory data) to 24 neurologists who have a special interest in stroke, and asked them to determine the most likely subtype diagnosis. The overall agreement was 0.64 (Kappa [K] = 0.54).(More)
OBJECTIVE To examine whether intravenous recombinant tissue plasminogen activator (rt-PA) treatment given in the acute phase of ischaemic stroke has a favourable effect on cognitive and functional outcome at six months post-stroke. METHODS The present study included 92 patients with a first-ever symptomatic infarct, of whom 25 (27%) were subjected to(More)
