Neuroimaging correlates of lateral postural control in older ambulatory adults

Abstract

Neuroimaging markers of poor postural control in healthy aging may help identify increased fall risk and design preventative fall strategies.

Linking objective measures of physical activity and capability with brain structure in healthy community dwelling older adults

“…Our results indicated no significant associations between subcortical or global BAG or DTI measures of brain integrity and postural control. For FA and MD, this was in line with a previous study reporting weak associations in the postural control association with regional FA, and a lack of association with MD ( Massa et al, 2019 ). We are not aware of previous studies testing for associations between subcortical BAG, including the cerebellum, or global BAG and postural control measured with a forced pressure platform.…”

A link between frontal white matter integrity and dizziness in cerebral small vessel disease

“…We found patients with idiopathic dizziness reported dizziness when upright in addition to elevated anxiety, depression and fear of falling. They had lower fractional anisotropy in the genu of the corpus callosum, the integrity of which is important to postural control ( Massa et al, 2019 ). Lower frontal white matter integrity occurred on a background of excess vascular risk, more hyperintensity in deep frontal white matter, poorer structural connectivity in a large bihemispheric white matter network, worse executive function, and poorer balance as known associations of SVD ( Wardlaw et al, 2019 ).…”

Functional Neural Networks of Physical Reserve Moderate the Association between White Matter Hyperintensity and Postural Balance in Older Adults with Subcortical Ischemic Vascular Cognitive Impairment

“…As a hallmark of SIVCI, 40 higher WMH is signi cantly correlated with poorer postural stability. 5,41 Hippocampal, WMH, and ICV were calculated and obtained from previous analysis. Brie y, ICV was estimated by normalizing each brain image to the MNI atlas template.…”
