Ukrainian Refugee PTSD Study: MRI Cortical Thickness and Trauma Exposure

60 Ukrainian refugees who arrived in Poland after the 2022 Russian invasion underwent MRI scans and psychopathological assessments. The data, published by Julian Maciaszek, shows a significant association between reduced right insular cortex thickness and higher odds of PTSD symptoms. The dataset was last updated on March 18, 2026.

Use Cases

• Train models to predict PTSD symptom severity based on cortical thickness measurements and trauma exposure counts.
• Analyze the moderating effect of brain structure on the relationship between post-migration living difficulties and PTSD.
• Investigate demographic and behavioral covariates (age, sex, education, smoking) in a refugee mental health context.

Strengths

• Dataset includes 60 subjects with both structural MRI neuroimaging and detailed behavioral assessments.
• Analysis controlled for multiple covariates including age, sex, education, and smoking status.
• Focus on a specific, timely population: Ukrainian refugees arriving after the 2022 invasion.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 22.3 KB, indicating limited scope.
