AI Article Synopsis

  • Individuals with Alzheimer's disease show specific issues in their working memory that affect how they understand and express language.
  • Research highlights that lower performance in language tasks is more linked to working memory deficits than to a loss of language knowledge itself.
  • The text also discusses strategies that could help improve communication skills for people with Alzheimer's.

Article Abstract

Individuals with Alzheimer's disease experience frontal lobe pathology and deficits in working memory processes are well documented. Less documented is how various working memory deficits impact communicative functioning. The performance data of individuals with mild and moderate Alzheimer's dementia on five tests of language comprehension and four tests of language expression are presented and discussed in the context of possible contributions from impaired working memory functions. The argument is advanced that diminished scores on tests of language comprehension and production result primarily from attenuated span capacity, difficulty focusing attention, encoding, and activation of long-term knowledge rather than from loss of linguistic knowledge. Techniques that may advantage Alzheimer's patients in the comprehension and expression of linguistic information are discussed.(1) Readers will become familiar with the typical functioning of individuals with Alzheimer's disease on common linguistic expression and comprehension tasks. (2) Readers will become familiar with the distinction between language knowledge and performance and its importance in understanding the cause of communication breakdowns in individuals with Alzheimer's disease. (3) Readers will become familiar with techniques that may facilitate the communicative functioning of individuals with Alzheimer's disease.

Purpose: Prelingual deaf children with cochlear implants show lower digit span test scores compared to normal-hearing peers, suggesting a working memory impairment. To pinpoint more precisely the subprocesses responsible for this impairment, we designed a sequence reproduction task with varying length (two to six stimuli), modality (auditory or visual), and compressibility (sequences with more or less regular patterns). Results on 22 school-age children with cochlear implants and 21 normal-hearing children revealed a deficit of children with cochlear implants only in the auditory modality.

Executive function (EF) impairments are prevalent in survivors of neonatal critical illness such as children born very preterm (VPT) or with complex congenital heart disease (cCHD). This paper aimed to describe EF profiles in school-aged children born VPT or with cCHD and in typically developing peers, to identify child-specific and family-environmental factors associated with these profiles and to explore links to everyday-life outcomes. Data from eight EF tests assessing working memory, inhibition, cognitive flexibility, switching, and planning in  = 529 children aged between 7 and 16 years was subjected into a latent profile analysis.

Fear extinction is the foundation of exposure therapy for anxiety and phobias. However, the stability of extinction memory diminishes over time, coinciding with fear recovery. To augment long-term extinction retention, the temporal distribution of extinction learning sessions is critical.

Major Depressive Disorder (MDD) is a widespread psychiatric condition impacting social and occupational functioning, making it a leading cause of disability. The diagnosis of MDD remains clinical, based on the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria, as biomarkers have not yet been validated for diagnostic purposes or as predictors of treatment response. Traditional treatment strategies often follow a one-size-fits-all approach obtaining suboptimal outcomes for many patients who fail to experience response or recovery.
