Tip-of-the-tongue (TOT) experiences increase with age and frequently heighten concerns about memory decline. We studied 73 clinically normal older adults participating in the Harvard Aging Brain Study. They completed a functional magnetic resonance i

Anticholinergic Amnesia is Mediated by Alterations in Human Network Connectivity Architecture

Autor: Keith A. Johnson, Trey Hedden, Dorene M. Rentz, Jasmeer P. Chhatwal, Aaron P. Schultz, Sarah E. Wigman, Brendon P. Boot, Reisa A. Sperling

Publikováno v: Cereb Cortex

Disrupted cholinergic neurotransmission plays a central role in Alzheimer’s disease, medication-induced memory impairment, and delirium. At the systems level, this suggests anticholinergic drugs may alter the activity and interplay of anatomically

Neuropsychiatric Symptoms and Functional Connectivity in Mild Cognitive Impairment

Autor: Gad A. Marshall, Sarah E. Wigman, Nancy J. Donovan, Brendan J. Guercio, Dorene M. Rentz, Keith A. Johnson, Rebecca E. Amariglio, Reisa A. Sperling, Catherine E. Munro, Aaron P. Schultz

Publikováno v: Journal of Alzheimer's Disease. 46:727-735

Background Neuropsychiatric symptoms (NPS), such as apathy and depression, commonly accompany cognitive and functional decline in early Alzheimer's disease (AD). Prior studies have shown associations between affective NPS and neurodegeneration of med

Amyloid-β deposition in mild cognitive impairment is associated with increased hippocampal activity, atrophy and clinical progression

Autor: Rebecca E. Amariglio, Mykol Larvie, Gad A. Marshall, Elizabeth C. Mormino, Aaron P. Schultz, Andrew Ward, Keith A. Johnson, Dorene M. Rentz, Sarah E. Wigman, Reisa A. Sperling, Willem Huijbers

Publikováno v: Brain. 138:1023-1035

Cross-sectional functional magnetic resonance imaging studies using a memory task in patients with mild cognitive impairment have produced discordant results, with some studies reporting increased hippocampal activity--consistent with findings in gen

Autor: Andrew Ward, Koene R. A. Van Dijk, Sarah E. Wigman, Aaron P. Schultz, Trey Hedden, Reisa A. Sperling, Jasmeer P. Chhatwal, Donald G. McLaren, Willem Huijbers

Publikováno v: NeuroImage. 102:620-636

Functional connectivity magnetic resonance imaging (fcMRI) is a powerful tool for understanding the network level organization of the brain in research settings and is increasingly being used to study large-scale neuronal network degeneration in clin

Development of a Psychometrically Equivalent Short Form of the Face–Name Associative Memory Exam for use Along the Early Alzheimer’s Disease Trajectory

Autor: Rose Bamfo, Sarah E. Wigman, Kathryn V. Papp, Kamolika Roy, Reisa A. Sperling, Julia Sherman, Maria Dekhtyar, Rebecca E. Amariglio, Dorene M. Rentz

Publikováno v: The Clinical Neuropsychologist. 28:771-785

Neuropsychologists are developing more challenging and specific tests to detect early and subtle changes in cognition related to preclinical Alzheimer's disease (AD). The 16-item Face-Name Associative Memory Exam (FNAME-16) is a challenging paired as

The Encoding/Retrieval Flip: Interactions between Memory Performance and Memory Stage and Relationship to Intrinsic Cortical Networks

Autor: Patrizia Vannini, Trey Hedden, Sarah E. Wigman, Reisa A. Sperling, Andrew Ward, Donald G. McLaren, Willem Huijbers, Aaron P. Schultz

Publikováno v: Journal of Cognitive Neuroscience. 25:1163-1179

fMRI studies have linked the posteromedial cortex to episodic learning (encoding) and remembering (retrieval) processes. The posteromedial cortex is considered part of the default network and tends to deactivate during encoding but activate during re
