Brief Summary

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.

Conditions

Obsessive-Compulsive Disorder

Outcome Measures

Primary Outcomes (1)

• Correlation of Microbiome to Disease via Relative Abundance Found in Microbiome Sequencing

  Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized with Obsessive-Compulsive Disorder
