“…The NAT (Schwartz et al, 2002(Schwartz et al, , 2003) is a standardized measure of naturalistic action that requires completion of three everyday tasks in the laboratory: (1) prepare toast with butter and jelly and prepare instant coffee with cream and sugar; (2) wrap a gift as a present; (3) prepare a lunchbox with a sandwich, snack and a drink, and pack a schoolbag with supplies for school. All objects are available on a U-shaped table, which permits easy view and reach of task items.…”

Error monitoring is critical to an individual's ability to function autonomously. This study characterized error detection and correction behaviors within the service of everyday tasks in individuals with dementia. Also, the impact of neuropsychological functioning on error detection and correction was examined. Fifty-three participants diagnosed with Alzheimer's disease (AD) or vascular dementia (VaD) were administered a neuropsychological protocol and the Naturalistic Action Test, which requires performance of three everyday tasks. Error detection, correction, and the point at which correction occurred (i.e., microslip-before the error was completed, immediate-just after the error was made, delayed-after performing other task steps) was coded. Dementia participants detected 32.7% of their errors and corrected 75.8% of detected errors. Participants were more likely to engage in microslips than delayed corrections. Tests of executive control and language predicted detection and correction variables; moreover, detection and correction were each related to different aspects of executive functioning. Microslips were related to naming ability. AD and VaD patients did not differ on detection0correction variables, and regression analyses indicated that dementia severity and memory abilities were unrelated to detection0correction. The results specify the error monitoring deficits in AD and VaD and have implications for improving functional abilities in dementia. (JINS, 2008, 14, 199-208.)

“…This metric is useful in assessing the degree of cognitive degeneration of a patient and to successfully discern the type of support he will need [56]. That is why many cognitive tests are based on ADLs performance such as the Kitchen Task Assessment [57] and the Naturalistic Action Test [58]. To summarize, the activities of daily living is a set of common activities that a normal person is supposed to be able to realize to be qualified as autonomous.…”

The aging population represents a growing concern of governments due to the extent that it will take in the coming decades and the speed of its evolution. This problem will result in increasing number of people affected by many diseases associated with aging such as the various types of dementia, including the sadly famous Alzheimer's disease. People with Alzheimer's must be assisted at all time during their everyday life. Technological assistance inside what is called a smart home could bring an affordable solution to solve this concern. One of the key issues to smart home assistance is to recognize the ongoing activities of everyday life made by the patient in order to be able to provide useful services at an appropriate moment. To do so, we must build a structured knowledge base of activities from which one or many intelligent agents (communicating with each other) would use information extracted from the various sensors to take a decision on what the inhabitant could be currently doing. The best way to build such an algorithm is to exploit constraints of different natures (logical, temporal, etc.) in order to circumscribe a library of activities. Many authors have emphasized the importance of the fundamental spatial aspect in activity recognition. However, only few works exist, and they are tested in a limited way that does not allow discerning the importance of dealing with space. Important spatial criterions, such as distance between objects, could help to reduce the number of hypotheses. Moreover, many errors can be detected only by using the spatial reasoning such as position problems (inappropriate objects are brought into the activity zone) or orientation of object issue (cup of coffee is upside down when pouring coffee).This thesis provides potential solutions to the problem outlined, which deals with spatial recognition of activities of daily living of a person with Alzheimer's disease. It proposes to adapt a theory of spatial reasoning, developed by Egenhofer, to a new model for recognition of activities. This new model allows identifying the ongoing activity using only qualitative spatial criterions which we demonstrate through the text that some could not have been identified otherwise. It also allows detection of new abnormalities related to the behavior of an individual in loss of autonomy. Finally, the model has been implemented and validated in carrying out activities in a smart home on the cutting edge of technology. These activities were derived from a clinical study with normal and mild to moderate Alzheimer subjects. The results were analyzed and compared with existing approaches to measure the contribution of this thesis. RÉSUMÉLe vieillissement de la population représente une préoccupation croissante des gouvernements en raison de l'ampleur qu'il prendra dans les prochaines décennies et la rapidité de son évolution.

“…Care was taken to obtain a stable baseline of performance in the first placebo phase, in order to make sure that changes in the amantadine administration stage were not due to random variation. Also, neglect was tested thoroughly with a large array of tests, a naturalistic action test (NAT, Schwartz et al, 2002) and the FIM. The results showed that a vast majority of the 17 measures employed showed no improvement.…”

Novel insights in rehabilitation of neglect

Visuospatial neglect due to right hemisphere damage, usually a stroke, is a major cause of disability, impairing the ability to perform a whole range of everyday life activities. Conventional and long-established methods for the rehabilitation of neglect like visual scanning training, optokinetic stimulation, or limb activation training have produced positive results, with varying degrees of generalization to (un)trained tasks, lasting from several minutes up to various months after training. Nevertheless, some promising novel approaches to the remediation of left visuospatial neglect have emerged in the last decade.These new therapy methods can be broadly classified into four categories. First, non-invasive brain stimulation techniques by means of transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS), after a period of mainly diagnostic utilization, are increasingly applied as neurorehabilitative tools. Second, two classes of drugs, dopaminergic and noradrenergic, have been investigated for their potential effectiveness in rehabilitating neglect. Third, prism adaptation treatment has been shown to improve several neglect symptoms consistently, sometimes during longer periods of time. Finally, virtual reality technologies hold new opportunities for the development of effective training techniques for neglect. They provide realistic, rich, and highly controllable training environments. In this paper the degree of effectiveness and the evidence gathered to support the therapeutic claims of these new approaches is reviewed and discussed. The conclusion is that for all these approaches there still is insufficient unbiased evidence to support their effectiveness. Further neglect rehabilitation research should focus on the maintenance of therapy results over time, on a more functional evaluation of treatment effects, on the design and execution of true replication studies and on the exploration of optimal combinations of treatments.
