AI Article Synopsis
- The study investigated how individuals with mild cognitive impairment (MCI) and dementia perform on social cognition tests, comparing these results to those without cognitive impairment.
- It involved a cross-sectional analysis of 321 older adults aged 80 and above, utilizing various social cognitive assessment tools and screening for levels of apathy and neurocognitive function.
- Findings indicated that participants with dementia showed notably worse social cognitive abilities compared to those with MCI and no cognitive impairment, particularly in emotional recognition and perspective-taking tasks.
Article Abstract
Objective: To study general and subdomain performance in measures of social cognition in individuals with mild cognitive impairment (MCI), and dementia, and to explore associations between social cognitive and neuropsychological subdomains.
Design: Cross-sectional study of participants from the Sydney Memory and Ageing Study (MAS).
Setting: Current data was collected in 2016-2018.
Participants: Community-dwelling older adults (n=321) aged 80 years and above, with no history of neurological or psychiatric conditions. Participants had dementia, MCI, or no cognitive impairment (NCI).
Measures: Social cognition was indexed using the Reading the Mind in the Eyes Test (RMET), the Interpersonal Reactivity Index - Perspective Taking (IRI-PT) and Empathic Concern (IRI-EC) subscales, and the Emotion Recognition Task (ERT). These subdomain scores were used to make a composite social cognition score. Apathy was measured via the Apathy Evaluation Scale (AES). Neurocognitive function was indexed using the Addenbrooke Cognitive Examination v3 (ACE-3).
Results: Dementia was associated with poorer overall social cognitive composite performance. MCI and dementia participants performed poorer on RMET and recognition of anger, disgust and happiness on ERT. RMET and ERT disgust remained significant after controlling for relevant covariates. Dementia participants performed poorer than MCI and NCI on the IRI-PT, IRI-EC, and AES. AES remained significant after regression. RMET was correlated with ACE-3 Fluency and/or Language in all study groups.
Conclusions: MCI is associated with poorer scores in specific social cognitive assessments. Dementia is somewhat associated with poorer scores in informant-rated social cognition scales, though this is no longer significant after accounting for apathy.

Over the past century, numerous studies have examined Jean Piaget's relationship with psychoanalysis. Until the 1970s, they often emphasized the value of a rapprochement between Piaget and Freud and highlighted the use of Piaget's ideas in therapeutic practice. Then from the 1980s onwards, several studies focused on the relationship between his work-seen as purely cognitive, to the exclusion of the social and the affective-and his conflicted relationship with his mother.

Purpose: Uncorrected visual impairment (VI) significantly impacts life quality and exacerbates age-related health issues. Social determinants of health (SDOH) are associated with uncorrected VI, but quantitative evidence is limited. This study investigated the link between SDOH and uncorrected VI among aging adults to identify disparities and improve vision care.

Aging Ment Health

Objectives: The concept of successful aging has been criticized for overlooking the experiences of older adults aging with disabilities, which may accentuate segregation and consolidate inequities. This qualitative study explored how older people living with early-onset mobility disabilities define successful aging, whether their definitions differ from those proposed by academia and from those of older people without disabilities, and to what extent older people with motor disabilities perceive themselves as aging successfully.
Method: Thirty-two people (20 women, 12 men) aged over 60 and living with motor disabilities for a minimum of 20 years were interviewed about their definition of successful aging and whether they considered that they were aging successfully.
Trehalose Ameliorates Zebrafish Emotional and Social Deficits Caused by CLN8 Dysfunction.

CLN8 and other neuronal ceroid lipofuscinoses (NCLs) often lead to cognitive decline, emotional disturbances, and social deficits, worsening with disease progression. Disrupted lysosomal pH, impaired autophagy, and defective dendritic arborization contribute to these symptoms. Using a zebrafish model, we identified significant impairments in locomotion, anxiety, and aggression, along with subtle deficits in social interactions, positioning zebrafish as a useful model for therapeutic studies in NCL.

Social isolation and health-related consequences of the COVID-19 pandemic may have significantly impacted quality of life in people with Parkinson's disease (PwPD). The effect of the COVID-19 pandemic specifically on subjective cognition and social functioning in PwPD is poorly understood. We conducted a longitudinal analysis of changes in subjective cognitive and social functioning in PwPD before (T1, 2017-2019) and during (T2, 2021) the COVID-19 pandemic.
