Normative Study of the Literacy Independent Cognitive Assessment in Illiterate and Literate Elderly Koreans
OBJECTIVE The aim of this study was to provide normative data on the Literacy Independent Cognitive Assessment (LICA) and to explore the effects of age, education/literacy, and gender on the performance of this test. METHODS Eight hundred and eighty-eight healthy elderly subjects, including 164 healthy illiterate subjects, participated in this study. None of the participants had serious medic...
متن کاملPerformance of illiterate and literate nondemented elderly subjects in two tests of long-term memory.
Cognitive evaluation in developing countries is a difficult undertaking due to low levels of schooling and particularly the illiteracy still frequent in the elderly. This study was part of the epidemiologic evaluation of dementia in Catanduva, Brazil, and had the objective of comparing the performance of illiterate and literate nondemented elderly individuals in 2 tests of long-term memory-the ...
متن کاملWhite Matter Microstructure in Idiopathic Craniocervical Dystonia
BACKGROUND Dystonias are hyperkinetic movement disorders characterized by involuntary muscle contractions resulting in abnormal torsional movements and postures. Recent neuroimaging studies in idiopathic craniocervical dystonia (CCD) have uncovered the involvement of multiple areas, including cortical ones. Our goal was to evaluate white matter (WM) microstructure in subjects with CCD using dif...
متن کاملWhite Matter Microstructure and Cognitive Function
In recent years, diffusion-weighted magnetic resonance imaging (DW-MRI) has been increasingly used to explore the relationship between white matter structure and cognitive function. This technique uses the passive diffusion of water molecules to infer properties of the surrounding tissue. DW-MRI has been extensively employed to investigate how individual differences in behavior are related to v...
متن کاملGender Differences in White Matter Microstructure
BACKGROUND Sexual dimorphism in human brain structure is well recognised, but little is known about gender differences in white matter microstructure. We used diffusion tensor imaging to explore differences in fractional anisotropy (FA), an index of microstructural integrity. METHODS A whole brain analysis of 135 matched subjects (90 men and 45 women) using a 1.5 T scanner. A region of intere...
