Care Setting
Research assessment using digital recordings of immediate and delayed Logical Memory paragraph recall.
Key Highlights
Eight immediate-recall and seven delayed-recall linguistic features were associated with cognitive impairment after adjustment for age, sex, education, and family relationships.
With demographic characteristics, the delayed-recall polyfeature score had an area under the precision-recall curve of 0.77, compared with 0.81 for traditional delayed Logical Memory scoring; the difference was not statistically significant.
Linguistic scores were moderately correlated with traditional Logical Memory scores, suggesting overlapping but not identical information.
Higher baseline delayed-recall polyfeature scores were associated with poorer TICS-m performance over follow-up, but did not predict a faster rate of cognitive decline.
The authors noted potential circularity, feature-selection bias, software limitations, and the need for replication and validation.

Monitoring & Follow-up
Risks
Patient & Prescribing Data
No treatment or prescribing intervention was studied. In the longitudinal analysis, a 30-point higher baseline delayed-recall polyfeature score was associated with a 2-point lower TICS-m score over 7 years.
Clinical Best Practices
The investigators cautioned that potential circularity and full-sample feature selection may have inflated performance estimates.
The investigators emphasized the need for validation in more diverse cohorts and clinical samples and cautioned that exploratory subtype analyses were underpowered and require replication.
Review identifies recurring sex-based differences across specialties, including lower use of intensive and guideline-compliant treatment among female patients.
