Association of Glymphatic Function, GMV, and Cognitive Function in ADHD

Anonymized data and R code supporting a study on glymphatic dysfunction in children with ADHD. The 69.3 KB dataset includes clinical symptom scores, glymphatic function measured by the ALPS index, cognitive test results, and grey matter volume from 50 brain regions. Manxue Zhang shared the materials on figshare in May 2026 to ensure research transparency and reproducibility.

Use Cases

• Correlating clinical symptom scores (SNAP, SDQ) with brain structure based on grey matter volume data
• Investigating the relationship between glymphatic function (ALPS index) and cognitive performance (CANTAB scores)
• Reproducing statistical analyses and figures from the original research paper using the provided R script

Strengths

• Includes the complete R analysis code for full reproducibility of the study's results
• Contains data from 50 specific brain regions of interest (ROIs) for detailed structural analysis
• Clinical and cognitive variables are clearly defined and derived from standardized scales and tests

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset's 69.3 KB size indicates a very limited scope, likely from a single study cohort
