Degenerative Brain Diseases and White Matter Injury
George Bartzokis,Po H. Lu +1 more
TL;DR: This chapter provides an overview of dynamic interdependence and complex signaling between all of the brain’s cellular elements with a special focus on glia and especially oligodendrocytes and their roles in achieving optimal brain function as well as triggering degenerative brain processes.
Journal ArticleDOI
Age-related memory decline is mediated by processing speed and myelin integrity
Po-Haong Lu,Grace J. Lee,Panthea Heydari,Alexander Couvrette,Michael Meghpara,Jim Mintz,Paul M. Thompson,George Bartzokis +7 more
TL;DR: Depression is associated with slowing in CPS, reduced white matter integrity, and higher risk of conversion toMCI, suggesting underlying pathological changes in white matter that may also be associated with prodromal AD.
Journal ArticleDOI
Influence of iron genes and gender on brain iron and cognition
George Bartzokis,Po H. Lu,Kathleen Tingus,Todd A. Tishler,Douglas G. Peters,Aurore Richard,Jim Mintz,Jim Mintz,Pablo Villablanca,J. Paul Finn,Gerhard Laub,James R. Connor +11 more
TL;DR: Irrespective of gene status, verbal memory is negatively associated with hippocampal iron accumulation in men and reducing brain iron accumulations in old age may be a worthwhile therapeutic target for age-related neurodegenerative diseases.
