RESUMEN
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 the City of Copenhagen. Acute treatment as well as all stages of rehabilitation are cared for within the stroke unit regardless of age, stroke severity, and premorbid condition. PATIENTS: 1197 patients with acute stroke. MAIN OUTCOME MEASURES: Primary outcome was measured as death, discharge to nursing home, or to own home. Secondary outcome was measured as neurological deficits and functional disabilities after completed rehabilitation and again 6 months after stroke onset, using the Scandinavian Neurological Stroke Scale and the Barthel Index. RESULTS: Stroke was initially very severe in 223 (19%) of the patients, severe in 171 (14%), moderate in 316 (26%), and mild in 487 (41%) patients. Two hundred and fifty (21%) patients died during hospital stay, 177 (15%) were discharged to nursing home, and 770 (64%) patients were discharged to their own home. After completed rehabilitation, 11% of survivors still had severe or very severe neurological deficits, 11% had moderate deficits, and 78% had no or only mild deficits; 20% were severely or very severely disabled, 8% were moderately disabled, 26% were mildly disabled, and 46% had no disability in activities of daily living. Detailed information on outcome stratified according to initial stroke severity/disability also is presented. CONCLUSIONS: This study provides a thorough description of the needs for stroke rehabilitation in the community and the amount of postrehabilitation disability in stroke survivors. For outcome prediction, the results can be used as a reliable tool for prognostication of the chances (or risks) of various outcomes in patients characterized by initial degree of stroke severity and/or functional disability using simple, reliable scores in the acute phase of stroke. However, the results should not be used as a guideline for selecting patients for rehabilitation in the acute phase because even the most severe cases regularly experience meaningful improvement during rehabilitation.

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 Copenhagen. Acute treatment as well as all stages of rehabilitation are cared for within the stroke unit regardless of age, stroke severity, and premorbid condition. PATIENTS: 1,197 patients with acute stroke. MAIN OUTCOME MEASURES: Weekly examinations of neurological deficits (using the Scandinavian Neurological Stroke Scale) and functional disabilities (Activity of Daily Living (ADL) measured by the Barthel Index) were performed from the time of acute admission to the end of rehabilitation. These evaluations were repeated 6 months poststroke. Time course of recovery was stratified according to initial stroke severity and disability. RESULTS: Functional recovery was completed within 12.5 weeks (95% confidence interval (CI) 11.6 to 13.4) from stroke onset in 95% of the patients. However, 80% of the patients had reached their best ADL function within 6 weeks (CI 5.3 to 6.7) from onset. The time course of functional recovery was strongly related to initial stroke severity. Best ADL function was reached within 8.5 weeks (CI 8 to 9) in patients with initially mild strokes, within 13 weeks (CI 12 to 14) in patients with moderate strokes, within 17 weeks (CI 15 to 19) in patients with severe strokes, and within 20 weeks (CI 16 to 24) in patients with very severe strokes. After these time-points, no significant changes occurred. However, a valid prognosis of functional outcome can be made much earlier. Best ADL function was reached by 80% of the patients with initially mild strokes within 3 weeks (CI 2.6 to 3.4), within 7 weeks (CI 6 to 8) of the patients with moderate strokes, and within 11.5 weeks (CI 10 to 13) of the patients with severe and very severe strokes. The time course of neurological recovery followed a pattern similar to that of functional recovery, but preceeded functional recovery by 2 weeks on average. CONCLUSIONS: A reliable prognosis can in all stroke patients be made within 12 weeks from stroke onset. Even in patients with severe and very severe strokes, neurological and functional recovery should not be expected after the first 5 months.

Two cases of late sequelae of accidental perivascular injection of Thorotrast (thorium dioxide) during carotid arteriography are presented. The complaints of the patients and the clinical findings are due to topical granulomatous and fibrous reactions with compression of the carotid artery and cranial nerves, and influence upon larynx and trachea. For future decades it will still be necessary to be aware of this possible cause of neck tumours with oto-laryngeal and neurological symptoms.
