Abstract

With dementia currently being one of the biggest healthcare challenges, an improvement in diagnosis represents a substantial improvement for the patients and medical experts. A frequently used diagnosis tool is the clock drawing test (CDT), cognitive short test typically conducted with pencil and paper and manually scored by a medical professional. This paper introduces a transparent approach for software-assisted scoring and screening of CDT, using a combination of deep learning elements and standard image recognition techniques. Unlike an end-to-end approach, our strategy involves dividing the process into distinct subprocesses. This division ensures that intermediate results are readily available throughout, establishing a robust and transparent foundation for the diagnostic process. A dataset containing 1236 CDT-scans is used for evaluating our algorithm’s ability to score the result into a category from 1 to 6 and the ability to classify pass or fail is assessed. Based on the results a component-wise software-assisted approach to CDT scoring seems to be a viable alternative to end-to-end systems.
