Dementias show differential physiological responses to salient sounds [PDF]

Frontiers in Behavioral Neuroscience, 2015
Abnormal responsiveness to salient sensory signals is often a prominent feature of dementia diseases, particularly the frontotemporal lobar degenerations, but has been little studied. Here we assessed processing of one important class of salient signals,

Semantic cognition: a re-examination of the recurrent network "hub" model [PDF]

, 2012
This paper explores a model of “semantic cognition” first described in Rogers et al. (2004). This model was shown to reproduce the behaviour of neurological patients who perform poorly on a variety of tests of semantic knowledge; thus purporting to ...

Application of the Semantic Fluency Test in the Screening of Mandarin-Chinese-Speaking Older Adults with Mild Dementia of the Alzheimer Type

Behavioral Sciences, 2023
Semantic fluency tests have been widely used as a screening test for dementia of Alzheimer type. However, few studies have explored the application of semantic fluency tests in Mandarin Chinese speakers.

Qualitative Verbal Fluency Components as Prognostic Factors for Developing Alzheimer’s Dementia and Mild Cognitive Impairment: Results from the Population-Based HELIAD Cohort

Medicina, 2022
Background and Objectives: The aim of the present study was to investigate the prognostic value of the qualitative components of verbal fluency (clustering, switching, intrusions, and perseverations) on the development of mild cognitive impairment (MCI ...

Neural dynamics of semantic categorization in semantic variant of primary progressive aphasia

eLife, 2021
Semantic representations are processed along a posterior-to-anterior gradient reflecting a shift from perceptual (e.g., it has eight legs) to conceptual (e.g., venomous spiders are rare) information. One critical region is the anterior temporal lobe (ATL)

Lost in semantic space: a multi-modal, non-verbal assessment of feature knowledge in semantic dementia [PDF]

, 2006
A novel, non-verbal test of semantic feature knowledge is introduced, enabling subordinate knowledge of four important concept attributes—colour, sound, environmental context and motion—to be individually probed.

Preservation of person-specific semantic knowledge in semantic dementia: does direct personal experience have a specific role?

Frontiers in Human Neuroscience, 2015
Semantic dementia patients seem to have better knowledge of information linked to the self. More specifically, despite having severe semantic impairment, these patients show that they have more general information about the people they know personally by

Deficits of semantic cognition in stroke aphasia: Underlying causes and ameliorating factors [PDF]

, 2012
Research suggests that semantic memory deficits can occur in at least three ways. Patients can (1) show amodal degradation of concepts within the semantic store itself, such as in semantic dementia (SD), (2) have an impairment of semantic control ...
