“…These errors were interpreted as the result of temporary failure of the control mechanisms in a multiple impaired cognitive system. However, as pointed out by Thioux et al (1999), a deficit in the supervisory attentional system per se may not explain a unidirectional pattern of intrusion errors such as the one they observed. Thioux and colleagues systematically investigated this phenomenon in a single-case study.…”

Objectives: Despite patients with mild dementia's capacity for independent living, they still have difficulty dealing with number processing and calculation due to continued cog nitive deterioration. Methods: This study used number processing and calculation tasks with number notation. The subjects of the study were comprised of two groups, an Alzhei mer's disease (AD) group (N= 16) and a healthy elderly group (N= 16). The study compared the error rates and error types in number processing and calculation between the two groups. Results: First, the AD group showed significantly higher errors in number production, num ber dictation, number reading and transcoding to verbal numerals compared to the con trol group. The AD group presented more diverse error types in number processing. Both groups had the highest error rates in syntactic errors. Second, the AD group demonstrated remarkably higher errors than the control group in subtraction and multiplication. In addi tion, the AD group showed higher diversity than the control group in calculation error types. Arithmetic rule errors and factual errors were the two most frequent errors for both groups. Third, there was a double dissociation between number processing and calculation. Conclusion: This study is significant in that it dealt with a detailed analysis of number process ing, specifically number transcoding to verbal numerals.

“…Moreover, detailed neuropsychological case descriptions showed that the breakdown of transcoding abilities may be highly selective and that transcoding errors may reflect the systematic decline of single components of the number processing system (Cipolotti & Butterworth, 1995;Cipolotti, 1995;Noël & Seron, 1993, 1995. Other studies on transcoding described intrusions of elements of the source code in the target code as typical error patterns in DAT (e.g., 3436 r 3thousandfourhundred36; Kessler & Kalbe, 1996;Tegner & Nyback, 1990;Thioux et al, 1999).…”

The present study investigated everyday numerical abilities in a group of 21 patients affected by mild to moderate dementia of Alzheimer's type (DAT). Though patients did not differ from a control group in standard laboratory tests tapping transcoding, number comparison, simple calculation, and estimation, they showed significant difficulties in numerical tasks embedded in an everyday context, such as handling money, a bus schedule, or a television program. Patients' difficulties were attributed to those multiple cognitive demands which are inherent to real situations as compared to well-structured abstract paper-and-pencil tasks. Overall, the study suggests that the examination of numerical abilities in DAT patients should go beyond abstract paper-and-pencil tasks which can only partially reflect the actual numerical skills in DAT and should therefore include also tasks simulating everyday life situations. Assessment of everyday numerical skills may be crucial in planning adequate support for patients, for example in handling money, but also in designing targeted training programs.
