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.Ä«ackward digit span dementia forward digit span short-term memory working memory. Our findings indicate that the backward DS task may detect WM decline in dementia, but the RST is more suitable for assessing dementia severity. The Digit Span Test is one of the most widely used tools for measuring verbal working memory. The number of digits that the person can remember is a measure of their working memory. The test is usually administered by asking the person to repeat a list of numbers forwards, and then backwards. Both types of DS tasks correlated with RST, only the RST distinguished dementia severity based on CDR. The digit span test is a measure of working memory. Usually, the examiner reads a list of numbers as. DS task scores were significantly correlated with RST scores. The Digit Sequencing Test alternatively called the Digit Span Test is a key tool for working verbal memory. Clinical Dementia Rating scale (CDR) was used to evaluate dementia severity. Twenty-six and 20 elderly individuals for the DS task and RST, respectively, were included as controls. By this latter view, verbal forward digit span is better described as a simple verbal short-term or immediate memory task and verbal backward digit span as a. 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. Forward/backward DS tasks and RST were performed in 15 elderly Japanese individuals with dementia. speakers performed three working memory tasks. 13 large sample of schizophrenia patients (n267). We investigated the ability of forward/backward DS tasks to discriminate dementia severity. We measured both types of working memory using the Digit Span forward (DF) and backward (DB) tasks in a. WORKING MEMORY AND BACKWARD DIGIT SPAN SERIESParticipants were presented with series of digits spoken verbally by the experimenter. This is a test of verbal WM, and requires participants to maintain information online while mentally manipulating that same information. This study aimed to compare the performance of individuals with dementia in forward and backward DS tasks to that in RST. Working memory span tasks Backward Digit Span (BDS). FR group made more errors in Digit span backward and sequences of. DS task and RST have not been directly compared in assessing dementia. patient groups, for example, FR and PD patients, in several short-term memory tasks. 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).
