  • Leukoaraiosis predicts hidden global functioning impairment in nondisabled older people: the LADIS (Leukoaraiosis and Disability in the Elderly) Study.

    • OBJECTIVES: To determine whether leukoaraiosis severity is independently associated with differences in global functioning in nondisabled elderly patients. DESIGN: Cross-sectional data analysis from an ongoing longitudinal multicenter and multinational study. SETTING: The Leukoaraiosis and Disability Study, a collaboration aimed at assessing leukoaraiosis as an independent predictor of the transition to disability in older people. PARTICIPANTS: Six hundred thirty-nine nondisabled subjects (288 men, 351 women, mean age+/-standard deviation 74.1+/-5.0) with magnetic resonance imaging-detected leukoaraiosis of different severity and presenting with one of the following: mild cognitive or motor disturbances, minor cerebrovascular events, or mood alterations or in whom leukoaraiosis was incidentally identified. MEASUREMENTS: Centralized assessment of leukoaraiosis severity according to the three severity degrees of the Fazekas scale; Disability Assessment for Dementia (DAD) Scale for measurement of global functioning. RESULTS: At baseline, 44% of participants had a mild, 31% a moderate, and 25% a severe degree of leukoaraiosis. A significant trend toward declining performance on the DAD Scale was apparent with increasing leukoaraiosis score severity (total score=98.8, 98.6, 97.5, respectively, in the three leukoaraiosis categories, analysis of variance P=.002). Similar trends were obtained for basic (P=.01) and instrumental (P<.001) function items. The statistical significance of these differences was confirmed in a multiple linear regression analysis correcting for numerous factors known to influence disability in older people. Executive function test performance declined along with increasing leukoaraiosis severity and was significantly related to DAD total score. CONCLUSION: Even in nondisabled elderly patients, levels of functional ability are related to white matter lesion severity. Executive dysfunction may mediate this relationship.

  • Urinary complaints in nondisabled elderly people with age-related white matter changes: the Leukoaraiosis And DISability (LADIS) Study.
  • 2008
  • Ingår i: Journal of the American Geriatrics Society. - 1532-5415. ; 56:9, s. 1638-43
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate, in a cohort of nondisabled elderly people, the association between urinary complaints and severity of age-related white matter changes (ARWMC). DESIGN: Cross-sectional data analysis from a longitudinal multinational study. SETTING: The Leukoaraiosis And DISability Study, assessing ARWMC as an independent predictor of the transition from functional autonomy to disability in elderly subjects. PARTICIPANTS: Six hundred thirty-nine subjects (288 men, 351 women, mean age 74.1+/-5.0) with magnetic resonance imaging (MRI)-detected ARWMC of different severity. MEASUREMENTS: ARWMC severity was graded on MRI as mild, moderate, and severe (Fazekas scale). MRI assessment also included ARWMC volumetric analysis and the count of infarcts. Urinary complaints (nocturia, urinary frequency, urgency, incontinence) were recorded based on subjects' answers to four questions. RESULTS: In comparing the three ARWMC severity groups, there was a significant difference only in prevalence of urgency, with 16% of subjects in the mild severity group, 17% in the moderate severity group, and 25% in the severe group (P=.03). Adjusting for age, sex, lacunar and nonlacunar infarcts, diabetes mellitus, and use of diuretics, severe ARWMC retained an independent effect in the association with urinary urgency (odds ratio=1.74, 95% confidence interval=1.04-2.90, severe vs mild group). Subjects with urinary urgency also had higher ARWMC volumes (25.2, vs 20.4 mm(3) in those without urinary urgency; P<.001). Urgency was confirmed to be associated with the severe degree of ARWMC, irrespective of complaints of memory, gait disturbances, or history of depression. CONCLUSION: In a cohort of nondisabled elderly people, severe ARWMC were associated with urinary urgency, independent of other potential confounders and vascular lesions of the brain.
