Journal ArticleDOI
Baseline MRI predictors of conversion from MCI to probable AD in the ADNI cohort.
TL;DR: It is indicated that degree of neurodegeneration of medial temporal structures was the best antecedent MRI marker of imminent conversion, with decreased hippocampal volume (left > right) being the most robust.
Journal ArticleDOI
Longitudinal Assessment of Cognitive Changes Associated With Adjuvant Treatment for Breast Cancer: Impact of Age and Cognitive Reserve
Tim A. Ahles,Andrew J. Saykin,Brenna C. McDonald,Yuelin Li,Charlotte T. Furstenberg,Brett Hanscom,Tamsin J. Mulrooney,Gary N. Schwartz,Peter A. Kaufman +8 more
TL;DR: Data demonstrated that age and pretreatment cognitive reserve were related to post-treatment decline in Processing Speed in women exposed to chemotherapy and that chemotherapy had a short-term impact on Verbal Ability.
Journal ArticleDOI
Executive dysfunction following traumatic brain injury: neural substrates and treatment strategies.
TL;DR: The nature of executive deficits following TBI, their neuroanatomical substrates, selected assessment and treatment strategies, and recent research findings and trends are summarized.
Journal ArticleDOI
Mechanisms of working memory dysfunction after mild and moderate TBI: evidence from functional MRI and neurogenetics.
TL;DR: Evidence from fMRI and neurogenetic studies that support the role of catecholaminergic dysregulation in the etiology of WM complaints and deficits after mild and moderate TBI are reviewed.
Journal ArticleDOI

TL;DR: MRI atrophy rate from baseline to 1 year is influenced by APOE genotype, imminent MCI to AD conversion, and AD-related neurodegeneration.
