title: Everyday problem solving among individuals with Alzheimer's disease.
abstract: Loss of functioning on complex tasks of daily living is an early indicator of dementia. The performance of 65 older adults with mild to moderate levels of Alzheimer's disease was examined on the Everyday Problems Test for the Cognitively Challenged Elderly (EPCCE), self-report inventories of functional performance, and a broad battery of clinical and neuropsychological measures. The EPCCE was designed to assess older adults on a set of complex tasks of daily living that involved not only global cognitive processes, but also higher-order executive functions. Participants solved an average of 45% of EPCCE tasks with significant differences in scores by disease severity. Performance was significantly related to global cognitive functioning and disease severity, and in particular to executive functions. Significant additional variance was accounted for by these executive functions beyond the variance accounted for by global cognitive measures.
