Journal ArticleDOI
Mild Cognitive Impairment: Clinical Characterization and Outcome
Ronald C. Petersen,Glenn E. Smith,Stephen C. Waring,Robert J. Ivnik,Eric G. Tangalos,Emre Kokmen +5 more
TL;DR: Patients who meet the criteria for MCI can be differentiated from healthy control subjects and those with very mild AD, and appear to constitute a clinical entity that can be characterized for treatment interventions.
Journal ArticleDOI
Prediction of AD with MRI-based hippocampal volume in mild cognitive impairment
Clifford R. Jack,Ronald C. Petersen,Yue Cheng Xu,Peter C. O'Brien,Glenn E. Smith,Robert J. Ivnik,Bradley F. Boeve,Stephen C. Waring,Eric G. Tangalos,Emre Kokmen +9 more
TL;DR: In older patients with MCI, hippocampal atrophy determined by premorbid MRI-based volume measurements is predictive of subsequent conversion to AD.
Journal ArticleDOI
Mild cognitive impairment: ten years later.
Ronald C. Petersen,Rosebud O. Roberts,David S. Knopman,Bradley F. Boeve,Yonas E. Geda,Robert J. Ivnik,Glenn E. Smith,Clifford R. Jack +7 more
TL;DR: This review summarizes the progress that has been made while also recognizing the challenges that remain and outlines the priorities for further research into mild cognitive impairment.
Journal ArticleDOI
Medial temporal atrophy on MRI in normal aging and very mild Alzheimer's disease
Clifford R. Jack,Ronald C. Petersen,Yue Cheng Xu,Stephen C. Waring,Peter C. O'Brien,Eric G. Tangalos,Glenn E. Smith,Robert J. Ivnik,Emre Kokmen +8 more
TL;DR: Age- and gender-adjusted, normalized MRI-based hippocampal volumetric measurements provide a sensitive marker of the MTL neuroanatomic degeneration in AD early in the disease process.
Journal ArticleDOI
Rates of hippocampal atrophy correlate with change in clinical status in aging and AD
Clifford R. Jack,Ronald C. Petersen,Yuecheng Xu,P. C. O'Brien,Glenn E. Smith,Robert J. Ivnik,B. F. Boeve,Eric G. Tangalos,Emre Kokmen +8 more
TL;DR: Rates of hippocampal atrophy match both baseline cognitive status and the change in cognitive status over time in elderly persons who lie along the cognitive continuum from normal to MCI to AD.
