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.
Guideline-Based Recommendations
Diagnosis
Management
- No treatment, management intervention, or management recommendation was reported in the supplied article text.
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.
