Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood.…

Moreno-Martinez, F. Javier; Goni-Imizcoz, Miguel; Spitznagel, Mary Beth – Brain and Cognition, 2011
Category specific semantic impairment (e.g. living versus nonliving things) has been reported in association with various pathologies, including herpes simplex encephalitis and semantic dementia. However, evidence is inconsistent regarding whether this effect exists in diseases progressively impacting diverse cortical regions, such as Alzheimer's…

Chow, Maggie L.; Brambati, Simona M.; Gorno-Tempini, Maria Luisa; Miller, Bruce L.; Johnson, Julene K. – Brain and Cognition, 2010
Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two…

Moreno-Martinez, F. Javier; Laws, Kieth R. – Brain and Cognition, 2007
There is a consensus that Alzheimer's disease (AD) impairs semantic information, with one of the first markers being anomia i.e. an impaired ability to name items. Doubts remain, however, about whether this naming impairment differentially affects items from the living and nonliving knowledge domains. Most studies have reported an impairment for…

Chainay, H.; Louarn, C.; Humphreys, G. W. – Brain and Cognition, 2006
We report data from a group of patients with mild Alzheimer's disease on a range of tasks requiring either stored semantic knowledge about objects (e.g., naming object use) or the execution of action to objects (e.g., miming and using objects). We found that the patients were impaired at miming in response to objects, even when they could describe…

Taler, Vanessa; Chertkow, Howard; Saumier, Daniel – Brain and Cognition, 2005
Alzheimer's disease (AD) subjects, healthy elderly, and young adults interpreted a series of novel noun-noun expressions composed of familiar object words. Subjects interpreted each item by selecting one of three possible definitions: a definition in which the referents of each noun were associated together in a particular context (e.g., rabbit…
