Investigating semantic control in amnestic mild cognitive impairment and mild dementia

Individuals in the preclinical stage of Alzheimer's disease (amnestic mild cognitive impairment [aMCI] and mild dementia) primarily exhibit episodic memory deficits, while the presence of semantic control impairments remains understudied. To explore …

Speaking: The Free Book

This book was written as a resource for teaching language production at the Bachelor’s and Master’s level or for initiating trainees on the topic more generally. Some basic knowledge of cognitive psychology and linguistics is assumed. These materials …

Declarative Learning, Priming, and Procedural Learning Performances comparing Individuals with Amnestic Mild Cognitive Impairment, and Cognitively Unimpaired Older Adults

Objective: While declarative learning is dependent on the hippocampus, procedural learning and repetition priming can operate independently from the hippocampus, making them potential targets for behavioral interventions that utilize non-declarative …

The Diagnostic Value of Language Screening in Primary Progressive Aphasia: Validation and Application of the Sydney Language Battery

Purpose: The three variants of primary progressive aphasia (PPA) differ in clinical presentation, underlying brain pathology, and clinical course, which stresses the need for early differentiation. However, brief cognitive tests that validly …

Repetition priming in individuals with amnestic Mild Cognitive Impairment and Alzheimer’s dementia: A systematic review and meta-analysis.

The literature on repetition priming in Alzheimer’s disease (AD) is inconsistent, with some findings supporting spared priming while others do not. Several factors may explain these inconsistencies, including AD severity (e.g., dementia vs. Mild …

How the speed of word finding depends on ventral tract integrity in primary progressive aphasia

Primary progressive aphasia (PPA) is a clinical neurodegenerative syndrome with word finding problems as a core clinical symptom. Many aspects of word finding have been clarified in psycholinguistics using picture naming and a picture-word …

SYDBAT

Nederlands De Sydney Language Battery (SYDBAT) is een screeningsinstrument ontworpen om PPA-subtypes uit elkaar te halen. Informatie over de test, validatie en normering vindt u in Eikelboom et al. (2017) en hier, waar u de test ook kunt vinden om te downloaden.

Investigating the semantic control network and its structural decline in mild cognitive impairment and mild dementia

Although the episodic and semantic memory systems have long been studied separately, recent literature revealed shared neural substrates, including the medial temporal lobe (MTL). One important aspect of semantic memory is semantic control, which …

The role of the uncinate fasciculus and inferior longitudinal fasciculus in healthy and disordered language production

The role of ventral fiber pathways in healthy and disordered language production

While neuroimaging research on language production has traditionally focused primarily on grey matter, several recent studies highlight the involvement of ventral and dorsal white matter pathways. A debated issue concerns the exact functional role of …
