Neuropsychological Characteristics Beyond Language in Primary Progressive Aphasia: A Multi

A 204.7 KB XLSX file from a multicenter observational study assessing cognitive and linguistic characteristics. The dataset, authored by Natalia Oliveira and last updated on 2026-04-24, compares individuals with Primary Progressive Aphasia (PPA) to healthy controls. It is shared under a CC0 1.0 license on figshare.

Use Cases

• Modeling cognitive decline patterns based on neuropsychological assessment scores.
• Analyzing linguistic impairment profiles in PPA subtypes mentioned in the study.
• Comparing patient performance to healthy control baselines for biomarker discovery.
• Training classifiers to differentiate between PPA variants using cognitive and linguistic features.

Strengths

• Data is from a multicenter observational study, suggesting a structured collection process.
• The dataset is focused on Brazilian Portuguese speakers, a less common language in PPA research.
• Shared under a permissive CC0 1.0 license, allowing for broad reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 204.7 KB file size indicates a limited scope, likely containing summary or assessment data rather than raw recordings.
