ICHD3 Primary Headache Syndromes Represented as a Diagnostic Matrix

A 12.7 KB matrix representation of primary headache syndromes from the International Classification of Headache Disorders (ICHD3). Pengfei Zhang published this dataset on figshare in 2026, demonstrating that all headache diagnoses can be represented in a 63-dimensional vector space. The matrix encodes phenotypes and characteristics to enable automated diagnosis and analysis.

Use Cases

• Automating headache diagnosis based on logical criteria encoded in the matrix.
• Analyzing relationships between headache phenotypes and characteristics using the bipartite projection.
• Investigating the fragmentation of specific diagnoses, such as paroxysmal hemicrania, based on Markov clustering results.
• Developing a graphical representation of headache classification criteria and their interconnections.

Strengths

• Derived from the ICHD3 gold standard for clinical trials and research.
• Enables systematic investigation of relationships between headache and phenotypes.
• The matrix representation allows for mathematical operations like row reduction, yielding 63 basis vectors.

Limitations

• The dataset is very small at 12.7 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring inspection after download.
• The data is contained within a PDF, which may require extraction for computational use.
