Matrix Representation of Primary Headache Syndromes in ICHD3

A 33.0 KB matrix encodes primary headache diagnoses from the International Classification of Headache Disorders (ICHD3) as logical statements. Pengfei Zhang published this dataset on figshare in 2026, demonstrating that headache phenotypes can be represented in a 63-dimensional vector space. The matrix format enables automated diagnosis and analysis of classification criteria.

Use Cases

• Automated diagnosis of headache disorders based on the encoded ICHD3 criteria.
• Analyzing relationships between headache phenotypes and characteristics using the matrix's bipartite projection.
• Investigating the fragmentation of specific diagnoses, such as paroxysmal hemicrania, through Markov clustering results.
• Exploring the vector space representation of headaches using the 63 derived basis vectors.

Strengths

• Derived from the gold-standard ICHD3 classification for headache medicine.
• Enables systematic analysis through a mathematical representation, yielding 63 basis vectors.
• Published under a permissive CC-BY-4.0 license.

Limitations

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