The Qualitative Scoring MMSE Pentagon Test (QSPT): A New Method for Differentiating Dementia with Lewy Body from Alzheimer’s Disease

Abstract: The differential diagnosis across different variants of degenerative diseases is sometimes controversial. This study aimed to validate a qualitative scoring method for the pentagons copy test (QSPT) of Mini-Mental State Examination (MMSE) based on the assessment of different parameters of the pentagons drawing, such as number of angles, distance/intersection, closure/opening, rotation, closing-in, and to verify its efficacy to differentiate dementia with Lewy Body (DLB) from Alzheimer's disease (AD). We establ… Show more

“…Different scoring criteria can likely explain the reason why other authors failed to detect differences between LBD and AD in pentagon copying [108,159], but more extended copying tests might show significantly lower performance in LBD with respect to AD patients [108]. Recently, it has been demonstrated that qualitative analysis of the pentagon copy test can provide additional information for distinguishing AD from LBD patients, since a lower number of angles is among distinctive features of LBD patients' copies [73,167], and can also predict development of LBD in MCI patients [74].…”

“…If this statement is violated, then the subject will receive 0 score, otherwise he/she will receive 1 score. The binary scoring between 0 and 1 on the pentagon drawing test is not favorable to represent the visuospatial performance, thus a new qualitative scoring method for MMSE pentagon test has been proposed by Caffarra [16]. We referred it as another reference method.…”

“…From another point of view, we can also take drawing process as a reflection of human cognition functions. In fact, drawing tests for disease screening are very common in the field of clinical psychology, where a number of validated drawing tests [11][12][13][14][15][16] have been applied in healthcare settings. Most of the tests are still conducted in paper-and-pencil form and relied on human decision by healthcare professionals, which usually involves subjective judgment.…”

“…Therefore, points regarding the drawing of the face of the clock and the sequence of placing the numbers 3, 6, 9, and 12 were not included for the patients at Erasmus Medical Center. Several methods have been proposed to score the PCT and the CDT [21,23,24]. We chose the qualitative scoring method of Caffarra et al [21] for the PCT and a modified scoring method of Royall et al [22] for the CDT, as we assumed that these scoring methods have a moderately high discriminative value due to their relatively wide scoring range.…”
