Differential involvement of the anterior temporal lobes in famous people semantics
(Frontiers media, 2016-08-30)
The ability to recognize a famous person occurs through semantic memory. Previous neuroimaging studies have shown that the anterior temporal lobes (ATLs) are involved in the recognition of famous people. However, it is ...
The role of the left anterior temporal lobe for unpredictable and complex mappings in word reading
(Frontiers media, 2017-04)
The anterior temporal lobes (ATLs) have been consistently associated with semantic processing which, in turn, has a key role in reading aloud single words. This study aimed to investigate (1) the reading abilities in ...
Subcortical amyloid load is associated with shape and volume in cognitively normal individuals
Subcortical Aβ associates to morphometry
Amyloid-beta (Aβ) deposition is one of the main hallmarks of Alzheimer’s disease. The study assessed the associations between cortical and subcortical 11C-Pittsburgh Compound B retention, namely in the hippocampus, ...
Subcortical amyloid relates to cortical morphology in cognitively normal individuals
Purpose Amyloid (Aβ) brain deposition can occur in cognitively normal individuals and is associated with cortical volume abnormalities. Aβ-related volume changes are inconsistent across studies. Since volume is composed ...
The impact of time and repeated exposure on famous person knowledge in amnestic Mild cognitive impairment and Alzheimer’s disease
Objective: Famous people knowledge has been shown to be impaired early in Alzheimer’s disease (AD) and amnestic mild cognitive impairment (aMCI). However, the question of whether recently acquired knowledge is more impaired ...
Comprehension of concrete and abstract words in semantic variant primary progressive aphasia and Alzheimer’s disease: a behavioral and neuroimaging study
The aim of this study was to investigate the comprehension of concrete, abstract and abstract emotional words in semantic variant primary progressive aphasia (svPPA), Alzheimer’s disease (AD), and healthy elderly adults ...
Amyloid burden and white matter hyperintensities mediate age-related cognitive differences
This study examined the additive versus synergistic contribution of beta-amyloid (Aβ) and white matter hyperintensities (WMHs) across 7 cognitive domains in 104 cognitively normal older adults. It also measured the extent ...
A MEG study of the neural substrates of semantic processing in semantic variant primary progressive aphasia
(Taylor & Francis, 2019-07-01)
Despite a well-documented pattern of semantic memory (SM) impairment, the patterns of brain activation during semantic processing in svPPA still remain poorly understood. The current study aimed to investigate the neural ...
The right temporal lobe variant of frontotemporal dementia: cognitive and neuroanatomical profile of three patients
The right temporal variant of frontotemporal lobar degeneration (Rtv-FTLD) is a focal degenerative condition affecting predominantly the right temporal lobe. The aim of this study was to further characterize the profile ...
Single and Multiple Domain Amnestic MCI: two sides of the same coin?
Single- and multiple-domain amnestic mild cognitive impairment: two sides of the same coin?
Background. Amnestic Mild Cognitive Impairment (aMCI) is considered a transition stage between normal aging and Alzheimer's disease (AD). Two main clinical subtypes of aMCI have been identified: 1) aMCI single domain ...
