Sensitivity of four psychometric tests to measure cognitive changes in brain aging-population-based studies.
Choosing the measure of cognition in an epidemiologic study investigating cognitive changes over time is a challenging question. A powerful measure must be able to detect small cognitive changes in all the range of cognition observed in the target population. This work aims at comparing the sensitivity to detect cognitive changes in the observed range of cognition of four widely used psychometr...
متن کاملNormalized Mini-Mental State Examination for assessing cognitive change in population-based brain aging studies.
BACKGROUND The Mini-Mental State Examination (MMSE) is widely used in population-based longitudinal studies to quantify cognitive change. However, its poor metrological properties, mainly ceiling/floor effects and varying sensitivity to change, have largely restricted its usefulness. We propose a normalizing transformation that corrects these properties, and makes possible the use of standard s...

BACKGROUND Providing a valid and sensitive measure of different domains of cognitive performance in epidemiologic studies of early old-age populations presents a methodological challenge, given the broad range of variability in cognitive functioning in this age group. OBJECTIVES (1) To provide data on the distribution of cognitive performance scores in a representative sample of an early old-...
