Knowledge of the frequency and remission of aphasia is essential for the rehabilitation of stroke patients and provides insight into the brain organization of language. We studied prospectively and consecutively an unselected and community-based sample of 881 patients with acute stroke. Assessment of aphasia was done at admission, weekly during the hospital(More)
OBJECTIVE To determine the time course of both neurological and functional recovery from stroke. DESIGN Prospective, consecutive, and community based. SETTING The stroke unit of a hospital in Copenhagen, Denmark. This setting receives all acute stroke patients admitted from a well-defined catchment area of 239,886 inhabitants within the city of(More)
Time course and degree of the recovery of walking function after stroke and the influence of initial lower extremity (LE) paresis were studied prospectively in a community-based population of 804 consecutive acute stroke patients. Walking function and degree of LE paresis were assessed weekly using the Barthel index and the Scandinavian Neurological Stroke(More)
Time course and degree of recovery of upper extremity (UE) function after stroke and the influence of initial UE paresis were studied prospectively in a community-based population of 421 consecutive stroke patients admitted acutely during a 1-year period. UE function was assessed weekly, using the Barthel Index subscores for feeding and grooming. UE paresis(More)
BACKGROUND In laboratory animals, cerebral ischaemia is worsened by hyperthermia and improved by hypothermia. Whether these observations apply to human beings with stroke is unknown. We therefore examined the relation between body temperature on admission with acute stroke and various indices of stroke severity and outcome. METHODS In a prospective and(More)
BACKGROUND Despite the common occurrence of seizures during the early phase of stroke (ES), the effect of ES on prognosis is not known. We determined the relationships between ES and stroke outcome and identified predictors of ES. METHODS In this community-based study, we prospectively and consecutively studied 1197 patients with acute stroke. We(More)
OBJECTIVE To evaluate the outcome of stroke stratified according to both initial stroke severity and initial level of disability. DESIGN Prospective, consecutive, and community based. SETTING A stroke unit of a hospital in Denmark. This setting receives all acute stroke patients admitted from a well-defined catchment area of 239,886 inhabitants within(More)
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia and a major risk factor for stroke. Many physicians remain reluctant to provide stroke prevention by anticoagulant therapy especially for elderly individuals with AF. Using multivariate regression analyses, we studied the characteristics and the prognosis of stroke in patients with AF. METHODS The(More)
Widely different incidences have been found for hemineglect in acute stroke, and there is no agreement on the consequences of hemineglect for activities of daily living recovery. We assessed acute admission visuo-spatial and personal hemineglect in a prospective, community-based study of 602 consecutive stroke patients. Hemineglect was found in 23%.(More)
Compensation by the unaffected upper extremity (UE) was studied in stroke patients who were unable to use the affected UE. The main aim was to evaluate the need of teaching compensatory techniques to stroke patients during rehabilitation of UE function. The study was prospective and community based and included 636 consecutive acute stroke patients. UE(More)
