![]() The backward DS task may be an effective screening measure for dementia signs in the elderly and may be used to identify patients requiring further assessments such as the RST to evaluate dementia severity based on WM performance. Number Sequencing, and Arithmetic), as well as for the more demanding working memory conditions. Our findings indicate that the backward DS task may detect WM decline in dementia, but the RST is more suitable for assessing dementia severity. For Digit Span Sequencing, the examinee is read a sequence of numbers and recalls the numbers in ascending order. memory (Digit Span Backward, Spatial Span Backward, Letter. Both types of DS tasks correlated with RST, only the RST distinguished dementia severity based on CDR. DS task scores were significantly correlated with RST scores. Clinical Dementia Rating scale (CDR) was used to evaluate dementia severity. Twenty-five nonwords were selected from the nonword phonological standard table from Saito, Saito, and Yoshimura (2000). Twenty-six and 20 elderly individuals for the DS task and RST, respectively, were included as controls. Digit span tasks typically require the respondent to listen to verbally presented digits, and then recall them either in the same order in which they are. Forward/backward DS tasks and RST were performed in 15 elderly Japanese individuals with dementia. Digit span with forward and backward re port, performed by each group in their native language, sug gests that the language rehearsal mechanisms for spoken language and for sign language differ in their processing. Results in dicate that language modality shapes the architecture of working memory. We investigated the ability of forward/backward DS tasks to discriminate dementia severity. speakers performed three working memory tasks. not for the verbal fluency tasks or digit span backwards. Keywords: Spatial working memory, Corsi Block Tapping Test, ageing, location memory, verbal working memory, Digit Span, visual working memory, n-back task. This study aimed to compare the performance of individuals with dementia in forward and backward DS tasks to that in RST. ly or visually presented digits in working memory, the central executive must monitor the. The performance of G2 (mean 9.33 SD 1.46) was significantly better than G1 (mean 5.86 SD 1.82) similarly, in the Digit Span Backward task (p<0.001). DS task and RST have not been directly compared in assessing dementia. The backward digit span (DS) task and reading span test (RST) are measures of WM. Dementia is characterized by the deterioration of working memory (WM). While further research is needed on the sources of variation in digit-span performance, we recommend the use of the visual digit-span task (forward or backward). ![]()
