Objective There is currently limited understanding of the course of change in everyday functioning that occurs with normal aging and dementia. To better characterize the nature of this change, we evaluated the types of errors made by participants as they performed everyday tasks in a naturalistic environment. Method Participants included cognitively healthy younger adults (YA; N = 55) and older adults (OA; N =88), and individuals with mild cognitive impairment (MCI: N =55) and dementia (N = 18). Participants performed eight scripted everyday activities (e.g., filling a medication dispenser) while under direct observation in a campus apartment. Task performances were coded for the following errors: inefficient actions, omissions, substitutions, and irrelevant actions. Results Performance accuracy decreased with age and level of cognitive impairment. Relative to the YAs, the OA group exhibited more inefficient actions which were linked to performance on neuropsychological measures of executive functioning. Relative to the OAs, the MCI group committed significantly more omission errors which were strongly linked to performance on memory measures. All error types were significantly more prominent in individuals with dementia. Omission errors uniquely predicted everyday functional status as measured by both informant-report and a performance-based measure. Conclusions These findings suggest that in the progression from healthy aging to MCI, everyday task difficulties may evolve from task inefficiencies to task omission errors, leading to inaccuracies in task completion that are recognized by knowledgeable informants. Continued decline in cognitive functioning then leads to more substantial everyday errors, which compromise ability to live independently.

The relationship between and the cognitive correlates of several proxy measures of functional status were studied in a population with mild cognitive impairment (MCI). Participants were 51 individuals diagnosed with MCI and 51 cognitively healthy older adults (OA). Participants completed performance-based functional status tests, standardized neuropsychological tests, and performed eight activities of daily living (e.g., watered plants, filled medication dispenser) while under direct observation in a campus apartment. An informant interview about everyday functioning was also conducted. Compared to the OA control group, the MCI group performed more poorly on all proxy measures of everyday functioning. The informant-report of instrumental activities of daily living (IADL) did not correlate with the two performance-based measures; however, both the informant-report IADL and the performance-based everyday problem-solving test correlated with the direct observation measure. After controlling for age and education, cognitive predictors did not explain a significant amount of variance in the performance-based measures; however, performance on a delayed memory task was a unique predictor for the informant-report IADL, and processing speed predicted unique variance for the direct observation score. These findings indicate that differing methods for evaluating functional status are not assessing completely overlapping aspects of everyday functioning in the MCI population.

Abstract.[Purpose] Memory impairment is a common sequela in patients with traumatic brain injury (TBI). Little is known about applications for memory training for patients with TBI. We investigated the effect of a memory training application in a patient with TBI. [Subjects and Methods] A 37 year-old male patient presented with memory impairment since onset of TBI resulting from a traffic accident. We developed a memory training application for use with a tablet PC. It consists of six stages. Each stage is composed of visual and auditory memory training parts. Two training sessions were conducted per day, five days per week, for a period of three months from nine months after onset to 11 months after onset.[Results] The patient's scores on the Memory Assessment Scale showed improvement after participating in the memory training program for a period of three months: global memory, 56.6%; short-term memory, 13.2%; visual memory, 75.0%; and verbal memory, 37.9%. [Conclusions] We observed significant improvement of memory function of this patient after memory training using this application. As a result of these findings, we believe that this application could be useful for improving memory impairment of patients with TBI.
