Abstract

Insights

Severe white matter hyperintensities (WMH) are linked to motoric cognitive risk syndrome (MCR) in older adults. This association suggests vascular brain changes contribute to MCR, impacting gait and cognition.

Area of Science:

  • Neurology
  • Gerontology
  • Radiology

Background:

  • Motoric Cognitive Risk Syndrome (MCR) is defined by slow gait and cognitive complaints.
  • MCR is linked to brain structural changes, but the role of white matter hyperintensities (WMH) remains unclear.

Purpose of the Study:

  • To investigate the association between white matter hyperintensities (WMH) and Motoric Cognitive Risk Syndrome (MCR).

Main Methods:

  • 1227 older adults underwent MRI to assess WMH.
  • Gait speed and subjective cognitive complaints were measured to identify MCR.
  • Demographic and medical data were collected as covariates.

Main Results:

  • 5.0% of participants had MCR, and 16.8% had severe WMH.
  • Severe WMH were significantly associated with MCR (OR 2.18, p=0.017), even after adjusting for covariates.
  • This association was consistent across various subgroups, including older age and absence of specific health conditions.

Conclusions:

  • Vascular brain changes, indicated by WMH, are associated with MCR.
  • The relationship between WMH and MCR is influenced by several factors.
  • Further research is needed to fully understand the pathophysiology of MCR.
