    • <i>Objective:</i> To examine the impact of corpus callosum (CC) tissue loss on the development of global cognitive and motor impairment in the elderly. <i>Methods:</i> This study was based on the Leukoaraiosis and Disability (LADIS) study. Assessment of cognitive and motor functions and magnetic resonance imaging (MRI) were done at baseline and at a 3-year follow-up in nondemented elderly subjects. <i>Results:</i> 328 of 639 LADIS subjects had MRIs at baseline and at the 3-year follow-up, which allowed for assessment of CC. Logistic regression revealed differential tissue loss rates in posterior CC in subjects converting to dementia, compared to nonconverters (p < 0.05). Anterior and posterior CC tissue loss was significantly correlated with self-perceived memory impairment in nonconverters (p < 0.05). CC tissue loss was also significantly associated with impaired single leg stance time (p < 0.01). <i>Conclusion:</i> The present longitudinal study on CC supports the role of callosal tissue loss in the development of global cognitive as well as motor impairment.

  • Physical Activity Prevents Progression for Cognitive Impairment and Vascular Dementia Results From the LADIS (Leukoaraiosis and Disability) Study
  • 2012
  • Ingår i: Stroke. - : Ovid Technologies (Wolters Kluwer Health). - 0039-2499 .- 1524-4628. ; 43:12, s. 3331-3335
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Purpose-We aimed to study if physical activity could interfere with progression for cognitive impairment and dementia in older people with white matter changes living independently. Methods-The LADIS (Leukoaraiosis and Disability) prospective multinational European study evaluates the impact of white matter changes on the transition of independent elderly subjects into disability. Subjects were evaluated yearly during 3 years with a comprehensive clinical protocol and cognitive assessment with classification of cognitive impairment and dementia according to usual clinical criteria. Physical activity was recorded during the clinical interview. MRI was performed at entry and at the end of the study. Results-Six hundred thirty-nine subjects were included (74.1 +/- 5 years old, 55% women, 9.6 +/- 3.8 years of schooling, 64% physically active). At the end of follow-up, 90 patients had dementia (vascular dementia, 54; Alzheimer disease with vascular component, 34; frontotemporal dementia, 2), and 147 had cognitive impairment not dementia. Using Cox regression analysis, physical activity reduced the risk of cognitive impairment (dementia and not dementia: beta=-0.45, P=0.002; hazard ratio, 0.64; 95% CI, 0.48-0.85), dementia (beta=-0.49, P=0.043; hazard ratio, 0.61; 95% CI, 0.38-0.98), and vascular dementia (beta=-0.86, P=0.008; hazard ratio, 0.42; 95% CI, 0.22-0.80), independent of age, education, white matter change severity, medial temporal atrophy, previous and incident stroke, and diabetes. Conclusions-Physical activity reduces the risk of cognitive impairment, mainly vascular dementia, in older people living independently. (Stroke. 2012; 43: 3331-3335.)
