Journal ArticleDOI
Mild Cognitive Impairment: An Overview
Ronald C. Petersen,Selam Negash +1 more
TL;DR: An algorithm is presented to assist the clinician in identifying subjects and subclassifying them into the various types of MCI, and directions for future research are proposed.
Journal ArticleDOI
Diversity and disparity in dementia: the impact of ethnoracial differences in Alzheimer disease.
TL;DR: It is proposed that education and outreach are a critical next step in the effort to understand AD as it relates to diverse populations, and emerging biomarker-based diagnostic tools may be useful in further characterizing diverse populations with AD.
Journal ArticleDOI
Depression, apolipoprotein E genotype, and the incidence of mild cognitive impairment: a prospective cohort study.
Yonas E. Geda,David S. Knopman,David A. Mrazek,Gregory A. Jicha,Glenn E. Smith,Selam Negash,Bradley F. Boeve,Robert J. Ivnik,Ronald C. Petersen,V. Shane Pankratz,Walter A. Rocca +10 more
TL;DR: Cognitively normal elderly individuals who develop depression are at increased risk of subsequent MCI and a synergistic interaction between depression and apolipoprotein E genotype is found.
Journal ArticleDOI
Patterns of atrophy differ among specific subtypes of mild cognitive impairment.
Jennifer L. Whitwell,Ronald C. Petersen,Selam Negash,Stephen D. Weigand,Kejal Kantarci,Robert J. Ivnik,David S. Knopman,Bradley F. Boeve,Glenn E. Smith,Clifford R. Jack +9 more
TL;DR: The pattern of atrophy in the amnestic MCI groups is consistent with the concept that MCI in most of these subjects represents prodromal AD, however, the varying patterns in the language and attention/executive subgroups suggest that these subjects may have a different underlying disorder.
Journal ArticleDOI
Risk of dementia in MCI: combined effect of cerebrovascular disease, volumetric MRI, and 1H MRS.
Kejal Kantarci,S. D. Weigand,Scott Przybelski,Maria Shiung,Jennifer L. Whitwell,Selam Negash,D. S. Knopman,B. F. Boeve,P. C. O'Brien,R. C. Petersen,Clifford R. Jack +10 more
TL;DR: Multiple magnetic resonance (MR) markers of underlying dementia pathologies improve the ability to identify patients with prodromal dementia over a single MR marker, supporting the concept that individuals with multiple brain pathologies have increased odds of dementia compared with individuals with a single pathology.
