Is this trial a fit for you?

Likely a good fit

Ideal candidates include veterans aged 35 and older who served in the 1990-1991 Gulf War and meet specific criteria for Gulf War Illness.

Probably not a fit

Patients with significant chronic diseases or cancers may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify blood lipids and metabolites that correlate with cognitive decline in veterans suffering from Gulf War Illness (GWI), particularly focusing on those with the APOE ε4 allele. It investigates how dietary, medical, and biological factors influence these blood components and their relationship to brain dysfunction. The research will validate blood biomarker signatures associated with GWI by examining lipid profiles and their connection to neuroinflammation and bioenergetic deficits. The study involves both veterans with GWI and control veterans to establish a comprehensive understanding of the condition.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic tools and targeted treatments for veterans suffering from Gulf War Illness.

How similar studies have gone: Other studies have shown promising results in identifying biomarkers related to cognitive decline and neuroinflammation, suggesting this approach may yield valuable insights.
