摘要
The corpus callosum is the largest hemispheric interconnection bundle in the human brain. Its anterior-posterior fiber caliber gradient can help in understanding the pathophysiological mechanisms underlying white matter changes both in old age and dementia. Here, the Leukoaraiosis and Disability (LADIS) study, a longitudinal cohort study, which shows an association between corpus callosum atrophy and cognitive and motor decline in the elderly, provides the possibility to consider the use of multimodal macro-microstructural imaging of corpus callosum as a marker of structural brain changes of physiological and pathological aging.
