2001–2011: A Decade of the LADIS (Leukoaraiosis And DISability) Study: What Have We Learned about White Matter Changes and Small-Vessel Disease?

2011 Cerebrovascular Diseases  
Abstract Over the last 20 years, evidence about the clinical correlates of cerebral white matter changes (WMC; also called leukoaraiosis) has been accumulating.  ...  The main results of the LADIS study have been released in 2009 with the demonstration that severe WMC more than double the risk of transition from an autonomous to a dependent status after 3 years of follow-up  ...  One major determinant of impaired functionality in relation to WMC, in addition to cognitive, motor and depressive disturbances, is represented by continence problems.  ...

Results: Higher levels of educational and occupational attainment were strongly related to baseline cognitive scores and predicted slower rate of decline in 3-year follow-up in measures of processing speed  ...  The deleterious effect of WMH on processing speed and memory was moderated by education and occupation. Education mitigated the relation of WMH volume on 7-year cognitive status.  ...  At baseline, all subjects had mild to severe WMH on brain MRI according to the modified scale of Fazekas, [13] but they had no or mild disability as assessed by the Instrumental Activities of Daily Living  ...
