“…Although some patients with dementia can perform routine activities and tasks adequately, the ability to solve more complex problems such as those found within work, social and domestic environments and in interpersonal relationships are usually affected 3 . Problem solving, measured by traditional neuropsychological tests or IADL scales 17 , 46 and decision making, evaluated by gambling tasks 47 , 48 are known to be affected in AD patients.…”

Judgment is the capacity to make decisions after considering available information, contextual factors, possible solutions and probable outcomes. Our aim was to investigate previous research studies regarding assessment of judgment in older adults with different degrees of cognitive impairment. To this end, a search of Pubmed and Lilacs electronic databases for studies published from January 1990 until August 2011 in English, Spanish and Portuguese was carried out. The terms used were "judgment" combined with the terms "dementia" or "Mild Cognitive Impairment" (MCI) or "Alzheimer's disease" (AD). Some studies showed that MCI and AD patients had impaired judgment. There is a lack of specific methods to measure judgment capacity, and data on judgment abilities in older adults with MCI and dementia are scarce. No studies with specific measures of judgment capacity in other dementias were found.

“…Rapcsak, Croswell, and Rubens [32] and Okazaki, Kasai, Meguro, Yamaguchi, and Ishii [33] reported that IADL performance in individuals with AD was affected by executive function and apraxia. Moreover, Grossi, Becker, Smith, and Trojano [34] found that attentionallocation disorders arose in individuals with AD because of a reduction in their ability to perceive stimuli simultaneously.…”

Objective: Despite the considerable importance of maintaining support for instrumental activities of daily living (IADLs) for patients with dementia living at home, there have been no formal investigations of what factors influence IADLs. Method: We administered various neuropsychological tests, the Timed Up and Go [TUG] test, and the Geriatric Depression Screening Scale-15 to 54 individuals in Japan who had visited a day care center or a preventative care class and who had either 23 mild Alzheimer's disease (mild AD) or 31 no dementia. IADLs were measured using the Self-Report Frenchay Activities Index. Results: The factors related to the domestic chores subscale of the Frenchay Activities Index were gender, backward digit recall performance (Wechsler Memory Scale-Revised [WMS-R]), and TUG test performance (R 2 = 0.53). Factors related to the leisure/work subscale were backward digit recall and logical memory II performance on the WMS-R, scores on the Behavioral Assessment of the Dysexecutive Syndrome, and TUG test performance (R 2 = 0.66). Finally, factors related to the outdoor subscale were backward digit recall, logical memory II, and the TUG test performance (R 2 = 0.62). Conclusions: The factors affecting IADLs among elderly individuals with mild AD or no dementia vary depending on the type of IADL. Notably, TUG test performance has a direct influence on all IADL types, and might relate to cognitive function. When providing preventative care or IADL support, it may be beneficial to evaluate and intervene with a focus on the cognitive and physical functions highlighted in this study.

“…Action deficits in AD have been explored from two main perspectives. The first involves ideational apraxia, which refers to the loss of the ability to perform purposeful actions involving the operation of objects without impaired perception of the relevant tools, muscle weakness or abnormal motor skill of the fingers . Ideational apraxia includes sequence errors, such as skipping or changing the order of praxis stages.…”

Background Various types of cognitive dysfunction could make it difficult to use multiple objects properly in Alzheimer's disease (AD). Aim To observe the qualitative feature of action deficits during a widely used praxis task and to clarify cognitive dysfunctions underlying the deficits. Methods We examined 80 patients with mild cognitive impairment (MCI), 84 patients with AD (69 mild and 15 moderate AD) and 40 healthy controls (HC) using the Alzheimer's Disease Assessment Scale cognitive subscale—Japanese version (ADAS‐J cog) and the Mini‐Mental State Examination (MMSE). Errors in the “praxis task” of ADAS‐J cog were classified into 4 types: apraxic, attentional, visuospatial and writing errors based on their qualitative features. The ratio of each error type was calculated and compared with each other. Results Participants with mild and moderate AD made significantly more errors in the praxis task compared with those in the HC and MCI groups. Qualitative analysis revealed that attentional errors occur more frequently in the MCI group than those in the HC group. For apraxic errors, there were significant differences between the MCI group and the mild/moderate AD groups. The more severe their general cognitive dysfunctions, the greater the variety of errors patients exhibit in the praxis task. Conclusion The results indicate that a main factor affecting the praxis task in MCI patients was attentional deficits, while various cognitive dysfunctions were related to action deficits in patients with AD. Our qualitative analysis for the praxis task revealed difference in action deficits in MCI and AD patients.

Disturbances in Everyday Life Activities and Sequence Disabilities in Tool use for Alzheimer Disease and Vascular Dementia

Abstract: Disturbances in everyday life activities of AD are associated with general cognitive impairment and sequence disabilities. By contrast, those of VaD may be based only on sequence disabilities.
