Predictors of Consent to Online and Genetic Research among Adults on the MindCrowd Cognitive Health Platform

2 months 1 week ago
CONCLUSION: Despite previous research demonstrating that Black and Hispanic MindCrowd participants were more willing to be contacted for future research than White participants, findings from this study suggest hesitancy to consent to online cognitive aging research and genetic testing. A more intentional approach may be necessary to retain MindCrowd participants from underrepresented communities in cognitive research studies.

Lysosomes signal through the epigenome to regulate longevity across generations

2 months 1 week ago
The epigenome is sensitive to metabolic inputs and is crucial for aging. Lysosomes act as a signaling hub to sense metabolic cues and regulate longevity. We found that lysosomal metabolic pathways signal through the epigenome to regulate transgenerational longevity in Caenorhabditis elegans. Activation of lysosomal lipid signaling and lysosomal adenosine monophosphate-activated protein kinase (AMPK) or reduction of lysosomal mechanistic target of rapamycin (mTOR) signaling increased the...

Empathy in mild cognitive impairment: a preliminary clinical comparative study in Southern Switzerland using the interpersonal reactivity index (IRI) and the story-based empathy task (SET)

2 months 1 week ago
CONCLUSION: These findings provide preliminary evidence of early empathy-related and theory of mind alterations in MCI, supporting the inclusion of social cognition assessments in standard neuropsychological protocols. The combined use of self-report and task-based instruments may enhance early identification of socio-emotional dysfunctions and inform personalized clinical interventions. The preliminary nature of this study is mainly due to the small sample size and the heterogeneous clinical...
