In this paper, we report on a study that consists of a semi-standardized history taking followed by two standardized neuropsychological tests, namely the SKT and the CERAD-NB. The tests include basic tasks such as naming objects, learning word lists, but also widely used tools such as the MMSE. Most of the tasks are performed verbally and should thus be suitable for automated scoring based on transcripts. For the first batch of 30 patients, we analyze the correlation between expert manual evaluations and automatic evaluations based on manual and automatic transcriptions. For both SKT and CERAD-NB, we observe high to perfect correlations using manual transcripts; for certain tasks with lower correlation, the automatic scoring is stricter than the human reference since it is limited to the audio. Using automatic transcriptions, correlations drop as expected and are related to recognition accuracy; however, we still observe high correlations of up to 0.98 (SKT) and 0.85 (CERAD-NB). We show that using word alternatives helps to mitigate recognition errors and subsequently improves correlation with expert scores.}, language = {en} } @inproceedings{BraunErzigkeitLehfeldetal.2022, author = {Braun, Franziska and Erzigkeit, Andreas and Lehfeld, Hartmut and Hillemacher, Thomas and Riedhammer, Korbinian and Bayerl, SebastianP and Sojka, Petr and Kopeček, Ivan and Pala, Karel and Hor{\´a}k, Aleš}, title = {Going Beyond the Cookie Theft Picture Test}, series = {Lecture notes in computer science ; 13502}, booktitle = {Lecture notes in computer science ; 13502}, publisher = {Springer International Publishing}, isbn = {978-3-031-16270-1}, doi = {10.48550/arXiv.2206.05018}, pages = {437 -- 448}, year = {2022}, language = {en} }
