The Bamberg Dementia Screening Test (BDST) – First Evidence Regarding the Diagnostic Usability of a “True Bedside” Test for Geriatric Inpatients

Published Online:September 14, 2015https://doi.org/10.1024/1016-264X/a000154

Abstract

Abstract. Due to physical limitations (e. g. difficulties in reading and writing), geriatric inpatients are often not able to complete relevant dementia screening tests. The Bamberg Dementia Screening Test (BDST) is a new dementia screening measure that can be administered in a few minutes as “true bedside” – test. 150 patients suffering from mild cognitive impairment (MCI) and mild or moderate dementia as well as a control sample of 40 cognitively unimpaired participants completed the BDST and the CERAD-Plus test battery. High correlations of BDST-subscores with CERAD subtests of corresponding content and between the total scores of the two tests could be found. Using the BDST, mild dementia and MCI patients could be discriminated from healthy controls with high sensitivity and specificity.


Der Bamberger Demenz Screening Test (BDST) – Erste empirische Evidenz hinsichtlich der Brauchbarkeit eines „true bedside“ Tests für geriatrische Patienten

Zusammenfassung. Patienten geriatrischer Stationen sind, da sie z. B. aufgrund ihrer körperlichen Einschränkungen schlecht zeichnen, lesen oder schreiben können, oft nicht in der Lage, klassische Demenzscreenings zu bearbeiten. Beim Bamberger Demenz Screening Test (BDST) handelt es sich um ein neu entwickeltes Screeningverfahren, das in wenigen Minuten als Bedside-Test durchführbar ist. 150 Patienten mit leichter kognitiver Störung (MCI), leichter und mittelschwerer Demenz sowie einer Kontrollgruppe von 40 unbeeinträchtigten Personen wurden der BDST und die CERAD-Plus Testbatterie vorgegeben. Es finden sich hohe Korrelationen der BDST-Subscores mit den inhaltlich entsprechenden CERAD Subtests sowie zwischen den Gesamtscores der beiden Verfahren. Mittels des BDST konnte zudem mit hoher Sensitivität und Spezifität zwischen gesunden Personen, Personen mit leichter kognitiver Störung (MCI) und Personen mit dementiellem Syndrom differenziert werden.
