DLBS: Longitudinal Brain MRI Scans Across the Adult Lifespan

Derived from the Dallas Lifespan Brain Study, this longitudinal neuroimaging dataset includes participants aged 21 to 89. Participants returned approximately every 3.5 to 5 years for up to three waves of data collection, contributing T1-weighted and T2-weighted MRI images. The dataset was created by chehablab and was last updated on Hugging Face in May 2026.

Use Cases

• Model brain aging trajectories based on longitudinal MRI scans.
• Train segmentation models for brain structures using T1-weighted and T2-weighted image pairs.
• Analyze lifespan changes in brain morphology from the multi-wave study design.
• Develop multimodal fusion models integrating structural MRI with other mentioned modalities like functional MRI.

Strengths

• Longitudinal design with up to three waves of data collection per participant.
• Covers a wide adult age range from 21 to 89 years.
• Includes multiple neuroimaging modalities such as T1-weighted and T2-weighted MRI.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
