Optical Coherence Tomography Artefact Burden Predicting Cognitive Decline

Serene Jia Ning Loke published a dataset on figshare in 2026. It contains data from a study of 507 Asian memory clinic participants who underwent baseline OCT imaging and annual neuropsychological assessments for up to 5 years. The research investigates associations between OCT scan artefacts and the risk of cognitive decline or conversion to dementia.

Use Cases

• Predicting cognitive decline based on the presence of OCT scan artefacts.
• Modeling the risk of dementia conversion in patients with cognitive impairment no dementia (CIND).
• Analyzing the prognostic value of specific artefact types like motion, shadow, or off-centre scans.

Strengths

• Data from a longitudinal study with up to 5 years of follow-up.
• Includes 507 participants with comprehensive neuropsychological assessments.
• Specific hazard ratios for outcomes are reported (e.g., HR=1.37 for cognitive decline).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Asian memory clinic cohort.
