Replication Code & Synthetic Data: ADNI-Inspired Alzheimer's Simulation

Curtis Huffman provides replication code and a synthetic dataset, last updated on April 20, 2026. The 2.1 MB resource includes R and RDATA files. The synthetic data is described as a version of confidential individual-level data from the Alzheimer's Disease Neuroimaging Initiative (ADNI).

Use Cases

• Testing statistical methods for Alzheimer's disease research based on synthetic ADNI-like data.
• Reproducing research findings in a privacy-preserving manner based on the described synthetic data frame.
• Developing data analysis pipelines for neuroimaging or clinical data using the provided R code.

Strengths

• Dataset is licensed under the permissive CC-BY-4.0 license.
• Files are provided in R-specific formats (R, RDATA) suitable for direct use in that environment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
