Impaired self-awareness (i.e. anosognosia) and altered metacognitive monitoring in memory tasks have both been evidenced in AD. Furthermore, cognitive studies showed disrupted interaction between self and memory cognitive systems in AD, reducing cognitive advantages of self-related memories (i.e. decreasing self reference effect, SRE) in these patients. However, how anosognosia relates to impaired metacognitive monitoring in AD, particularly for self-related memories, is still an open question. To investigate this question, an ecological memory task based on face-name associations was administrated to 20 healthy older controls (HC) and 20 mild AD patients. The influence of self-reference at encoding was assessed on subsequent name recall and recollective experience, as well as on predictive (feeling-of-knowing, FOK) and postretrieval (judgments-of-confidence, JOC) metacognitive judgments on name recognition in all participants. Furthermore relationships between metacognitive outcomes and awareness of daily cognitive and behavioral impairment was examined in AD. Altered SRE was evidenced in name recall and recollective experience in AD. Patients also showed impaired FOK and JOC, as well as lower awareness of their daily functioning impairment (anosognosia). Nevertheless, differential effect of self on metacognitive judgment in AD and HC was only observed on JOC for false memories. Importantly, anosognosia for behavioral disorders was related to post-retrieval confidence for false recognition of self-related items in AD patients. Thus, anosognosia concerning behavioral disorder and altered post-retrieval monitoring of self-related memories appear to be related in AD. We hypothesized that impaired monitoring of personal false memories may lead AD patients to rely on distorted recent reality when providing judgment about their everyday behavioral functioning.

Objective: To study awareness of cognitive dysfunction in patients with very mild Alzheimer's disease (AD) and subjects with mild cognitive impairment (MCI). Methods: A complaint interview covering 13 cognitive domains was administered to 82 AD and 79 MCI patients and their caregivers. The patient groups were comparable according to age and education, and Mini Mental State Examination (MMSE) scores were ≥ 24 in all cases. The discrepancy between the patients' and caregivers' estimations of impairments was taken as a measure of anosognosia. Results: Self-reports of cognitive difficulties were comparable for AD and MCI patients. However, while in comparison to caregivers MCI patients reported significantly more cognitive impairment (p < 0.05), AD patients complained significantly less cognitive dysfunctions (p < 0.001). Conclusions: While most MCI patients tend to overestimate cognitive deficits when compared to their caregiver's assessment, AD patients in early stages of disease underestimate cognitive dysfunctions. Anosognosia can thus be regarded as a characteristic symptom at a stage of very mild AD (MMSE ≥ 24) but not MCI. Accordingly, medical history even in mildly affected patients should always include information from both patient and caregiver. Copyright (C) 2005 S. Karger AG, Basel. [less ▲]

Chez les patients atteints de maladie d’Alzheimer (MA), on observe dès les stades débutants d’une part un phénomène d’anosognosie, qui peut être considéré comme une altération de la conscience de soi, et d’autre part un dysfonctionnement des processus de monitoring mnésique [1]. En outre, l’interaction entre le soi et la mémoire (conférant un bénéfice mnésique pour les informations associées à soi), apparaît significativement altérée dans la MA. Dans la présente étude, nous avons examiné les relations entre l’anosognosie et le monitoring lors de la récupération en mémoire d’informations expérimentalement associées à soi. Nous avons évalué les processus de monitoring lors de la récupération en mémoire à l’aide d’une tâche expérimentale de 32 paires visage-prénom, ainsi que l’anosognosie à l’aide du questionnaire d’anosognosie dans la démence (AQD, [2]) chez 20 patients MA et 20 personnes âgées contrôles (AC). Durant la phase d’encodage, les paires visage-prénom ont été présentées aux participants soit comme des personnes faisant partie de leur famille (soi) soit comme des personnes faisant partie de la famille de l’expérimentateur (autrui). Ensuite, nous avons évalué les jugements de « sentiment de savoir » (FOK), les performances de rappel et de reconnaissance, ainsi que les jugements de confiance (JOC) des participants pour le nom de chaque personne lorsque son visage était présenté. Nos résultats ont confirmé l’altération de la conscience de soi (c’est-à-dire l’anosognosie mesurée par l’AQD), l’altération du bénéfice mnésique pour les informations associées à soi, ainsi que l’altération des processus de monitoring lors de la récupération en mémoire (FOK et JOC) chez les patients MA. Néanmoins, une modification de l’interaction entre le soi et les processus de monitoring chez ces patients a été observée uniquement au niveau des sentiments de confiance pour des souvenirs erronés. Nous avons également observé que l’anosognosie des troubles comportementaux était significativement corrélée à la proportion de sentiments de confiance pour des reconnaissances erronées sur les items associés à soi. En conclusion, notre étude suggère que l’altération de la conscience des troubles comportementaux chez les patients MA pourrait être liée à un déficit de monitoring des souvenirs liés à soi. C’est-à-dire que la conscience altérée du dysfonctionnement au quotidien pourrait s’appuyer sur des souvenirs personnels déformés. [less ▲]

The binomial coefficient of two words u and v is the number of times v occurs as a subsequence of u. Based on this classical notion, we introduce the m-binomial equivalence of two words refining the abelian equivalence. The m-binomial complexity of an infinite word x maps an integer n to the number of m-binomial equivalence classes of factors of length n occurring in x. We study the first properties of m-binomial equivalence. We compute the m-binomial complexity of the Sturmian words and of the Thue-Morse word. We also mention the possible avoidance of 2-binomial squares. [less ▲]

The binomial coefficient of two words $u$ and $v$ is the number of times $v$ occurs as a subsequence of $u$. Based on this classical notion, we introduce the $m$-binomial equivalence of two words refining the abelian equivalence. Two words $x$ and $y$ are $m$-binomially equivalent, if, for all words $v$ of length at most $m$, the binomial coefficients of $x$ and $v$ and respectively, $y$ and $v$ are equal. The $m$-binomial complexity of an infinite word $x$ maps an integer $n$ to the number of $m$-binomial equivalence classes of factors of length $n$ occurring in $x$. We study the first properties of $m$-binomial equivalence. We compute the $m$-binomial complexity of two classes of words: Sturmian words and (pure) morphic words that are fixed points of Parikh-constant morphisms like the Thue--Morse word, i.e., images by the morphism of all the letters have the same Parikh vector. We prove that the frequency of each symbol of an infinite recurrent word with bounded $2$-binomial complexity is rational. [less ▲]

The term 'locked-in'syndrome (LIS) describes a medical condition in which persons concerned are severely paralyzed and at the same time fully conscious and awake. The resulting anarthria makes it impossible for these patients to naturally communicate, which results in diagnostic as well as serious practical and ethical problems. Therefore, developing alternative, muscle-independent communication means is of prime importance. Such communication means can be realized via brain-computer interfaces (BCIs) circumventing the muscular system by using brain signals associated with preserved cognitive, sensory, and emotional brain functions. Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success. Recently, also blood flow-based neuroimaging methods, such as functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS), have been explored in this context. After reviewing recent literature on the development of especially hemodynamically based BCIs, we introduce a highly reliable and easy-to-apply communication procedure that enables untrained participants to motor-independently and relatively effortlessly answer multiple-choice questions based on intentionally generated single-trial fMRI signals that can be decoded online. Our technique takes advantage of the participants' capability to voluntarily influence certain spatio-temporal aspects of the blood oxygenation level-dependent (BOLD) signal: source location (by using different mental tasks), signal onset and offset. We show that healthy participants are capable of hemodynamically encoding at least four distinct information units on a single-trial level without extensive pretraining and with little effort. Moreover, real-time data analysis based on simple multi-filter correlations allows for automated answer decoding with a high accuracy (94.9%) demonstrating the robustness of the presented method. Following our 'proof of concept', the next step will involve clinical trials with LIS patients, undertaken in close collaboration with their relatives and caretakers in order to elaborate individually tailored communication protocols. As our procedure can be easily transferred to MRI-equipped clinical sites, it may constitute a simple and effective possibility for online detection of residual consciousness and for LIS patients to communicate basic thoughts and needs in case no other alternative communication means are available (yet)--especially in the acute phase of the LIS. Future research may focus on further increasing the efficiency and accuracy of fMRI-based BCIs by implementing sophisticated data analysis methods (e.g., multivariate and independent component analysis) and neurofeedback training techniques. Finally, the presented BCI approach could be transferred to portable fNIRS systems as only this would enable hemodynamically based communication in daily life situations. [less ▲]

A method to improve the behavior of the numerical discretization of a rotated diffusion operator such as, for example, the isopycnal diffusion parameterization used in large-scale ocean models based on the so-called z-coordinate system is presented. The authors then focus exclusively on the dynamically passive tracers and analyze some different approaches to the numerical discretization. Monotonic schemes are designed but are found to be rather complex, while simpler, linear schemes are shown to produce unphysical undershooting and vershooting. It is suggested that the choice of an appropriate discretization method depends on the importance of the rotated diffusion in a given simulation, whether the field to be diffused is dynamically active or not.

Attention deficit and hyperactivity disorder (ADHD) is one of the most frequent disorders in childhood and adolescence. Both neurocognitive and environmental factors have been related to ADHD. The current study contributes to the documentation of the predictive relation between early attachment deprivation and ADHD. Data were collected from 641 adopted adolescents (53.2 % girls) aged 11–16 years in five countries, using the DSM oriented scale for ADHD of the Child Behavior Checklist (CBCL) (Achenbach and Rescorla, Manual for the ASEBA school-age forms and profiles. University of Vermont, Research Center for Children, Youth and Families, Burlington, 2001). The influence of attachment deprivation on ADHD symptoms was initially tested taking into consideration several key variables that have been reported as influencing ADHD at the adoptee level (age, gender, length of time in the adoptive family, parents’ educational level and marital status), and at the level of the country of origin and country of adoption (poverty, quality of health services and values). The analyses were computed using the multilevel modeling technique. The results showed that an increase in the level of ADHD symptoms was predicted by the duration of exposure to early attachment deprivation, estimated from the age of adoption, after controlling for the influence of adoptee and country variables. The effect of the age of adoption was also demonstrated to be specific to the level of ADHD symptoms in comparison to both the externalizing and internalizing behavior scales of the CBCL. Deprivation of stable and sensitive care in infancy may have long-lasting consequences for children’s development. [less ▲]
