NQPC-13 THE EFFICACY OF RAVEN’S COLORED PROGRESSIVE MATRICES FOR PATIENTS WITH BRAIN TUMOR

BACKGROUND: Mini-Mental State Examination (MMSE) and Raven’s Colored Progressive Matrices (RCPM) are cognitive function tests used to assess speech and visual cognitive functions in patients with brain tumor and aphasia, respectively. We investigated the distribution and correlation between MMSE and RCPM scores in patients with brain tumor, who underwent tumor resection, to identify the test characteristics. METHOD: Among the 122 patients who underwent tumor resection in our hospital from April 2018 to March 2019, and potentially required rehabilitation, 43 patients (i.e., 19 men and 24 women) who underwent pre- and post-operative MMSE and RCPM were further investigated. Median age during surgery was 54 years (20–86 years). Relationship between the pre- and post-operative MMSE and RCPM scores were evaluated using the Spearman’s rank correlation coefficient. Additionally, we investigated the characteristics of patients who scored low on either of the tests. RESULTS: Median pre- and post-operative MMSE scores were 29 points (14–30) and 29 points (21–30), respectively. Median pre- and post-operative RCPM scores were 33 points (25–36) and 35 points (18–36), respectively. The pre- and post-operative correlation coefficient between MMSE and RCPM scores were 0.376 and 0.699, respectively. Among the 12 patients with lower pre-operative scores on MMSE, as compared to RCPM, 8 patients had impaired attention and 4 patients had aphasia. One patient who scored lower on RCPM test, as compared to MMSE, had reduced analogical reasoning ability. Postoperatively, no patient scored low on MMSE as compared to RCPM, and one patient who scored lower on RCPM than MMSE had left hemi-spatial neglect. CONCLUSION: The pre-operative cognitive functions of patients with impaired attention and aphasia can be evaluated with RCPM using visual tasks without interference caused by these impairments. Minute pre- and post-interventional cognitive changes can be assessed with both MMSE and RCPM together.
