| Summary, etc. | RésuméLe vieillissement s’accompagne de nombreux changements tant au niveau physique, biologique, psychoaffectif que cognitif. Le vieillissement cérébral est un processus complexe et hétérogène. L’imagerie par résonance magnétique permet d’identifier et de quantifier in vivo une partie de ces changements. Les données d’imagerie par tenseur de diffusion (DTI) suggèrent une altération de l’intégrité des faisceaux de substance blanche, générant des changements dans la diffusion des molécules d’eau. L’objectif de cette revue est d’introduire les principes généraux de la DTI puis, en s’appuyant sur les travaux conduits dans ce domaine, de décrire les altérations liées à l’âge dans les faisceaux de substance blanche et leur impact sur les fonctions cognitives, notamment les fonctions exécutives et la mémoire. Un intérêt particulier sera porté à la mémoire prospective ou mémoire des intentions futures. |
| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | Impact of age-related alterations of white matter on cognitive performance: a review of DTI studiesAging is accompanied by many physical, biological, psychoaffective and cognitive changes. Cerebral aging is a complex and heterogeneous process. Magnetic resonance imaging can be used to identify and quantify, at least part of, these cerebral alterations in vivo. Diffusion tensor imaging (DTI) measures the alterations of the integrity of white matter fibers through changes in the diffusion of water molecules in the brain. The main objective of this review is to introduce the principles of DTI and to review studies describing the age-related alterations in brain white matter and their impact on cognitive functions including executive functions and memory. A particular emphasis will be laid on prospective memory, defined as memory of future intentions. |
