This manual procedure is time-consuming, slow and scores vary depending on the clinician’s experience, motivation and tiredness. To obtain a score, a trained clinician inspects a patient’s ROCF drawing and quantifies deviations from the original figure. The Rey-Osterrieth complex figure (ROCF) is the state–of-the-art assessment tool for neuropsychologists across the globe to assess the degree of non-verbal visual memory deterioration. Memory deficits are a hallmark of many different neurological and psychiatric conditions. Section candidates by an average of 75% without the loss of a single Unary spatial metrics have been implemented to reduce the possible All but one section in the testĭata was located (99.3% success) and 78% of the perceptual gradesĬalculated were within 5% of grades generated by independent raters. Grading of the basic geometric features (triangles, rectangles andĭiamonds) have been most successful. Making this an extremely difficult task however location and perceptual Systems (the Osterrieth Scoring System), with the ultimate goal ofĪutomating the scoring system. Technique to locate the scoring sections of the most common of these The paper gives details of the current progress of a novel Many scoring systems are used to quantify the accuracy of theĭrawings these are currently implemented by hand in a subjective Neuropsychological test for visual perception and long term visual The goal of our system was to support the professionals providing a qualitative judgement for each of the 18 patterns, estimating the most probable diagnosis for the patient, and identifying the main signs associated to the obtained diagnosis.The Rey Osterrieth Complex Figure (ROCF) is a widely used In this work, we developed a decision support system (DSS) for the evaluation of the ROCF copy test in the common practice using retrospective information from previously performed drawings.

Even promising, such methods are still far away from clinical validation and translation. Previous works addressed those problems by proposing tablet-based automated evaluation systems. The standard scoring system however have limitations related to its subjective nature and its inability to evaluate other cognitive domains than constructional abilities. In the copy test, the patient has to draw a replica of a 18-pattern image and the outcome is a score based on the accuracy of the overall drawing. The Rey Osterrieth complex figure (ROCF) is one of the most used neuropsychological tests for the assessment of mild cognitive impairment (MCI) and dementia.
