ICHD3 Primary Headache Syndromes Represented as a Diagnostic Matrix

A matrix representation of primary headache syndromes from the International Classification of Headache Disorders (ICHD3). The dataset encodes diagnostic criteria as a biadjacency matrix, enabling automated diagnosis and analysis. It was created by Pengfei Zhang and last updated on 2026-05-11.

Use Cases

• Automated diagnosis of headache disorders based on the logical criteria encoded in the matrix.
• Graphical analysis of relationships between headache phenotypes and diagnostic characteristics.
• Systematic investigation of the structure and fragmentation of diagnoses within the ICHD3 classification.
• Dimensionality reduction to identify basis vectors spanning the space of headache phenotypes.

Strengths

• Encodes the gold-standard ICHD3 classification into a structured, machine-readable matrix format.
• Enables mathematical operations like bipartite projection, Markov clustering, and row reduction, revealing 63 basis vectors.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and modification.

Limitations

• The dataset is small (42.4 KB), indicating limited scope, likely covering only primary headache diagnoses.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
