| Opplysninger | Clinical observations and research studies have documented thatpeople with Alzheimer's disease and related disorders (ADRD) appearto regress developmentally during the course of the disease. Thepurpose of this study was to prospectively determine the associationbetween changes in Piaget levels of cognitive development andcognitive decline in nursing home residents in various stages ofADRD. Fifty-seven people were tested three times at yearly intervals,using the Folstein Mini-Mental State Exam to determine cognitivelevels and a set of 14 Piaget tasks to determine cognitivedevelopmental levels: 1) Formal Operations; 2) Concrete Operations;3) Preoperational: and 4) Sensorimotor, Mean MMSE scores declinedfrom 12.7 to 9.4, and there was a downward trend in Piaget levelsover the study period. ANOVA showed significant differences(p<0.0005, Years 1, 2,3) in MMSE scores among all Piaget levels, andSpearman rho analysis showed significant correlations between Piagetlevels and MMSE for each year (p<0.0005, Years 1, 2, 3). The resultssuggest that there is a concurrent decline in cognitive developmentallevels and cognition in people in various stages of Alzheimer'sdisease and related disorders.
