Thiamine deficiency in patients with chronic migraine: A case-control study.
Headache | 2026
Observational studySummary
Thiamine deficiency is noted in various neurological disorders, including chronic migraine (CM). This study aimed to compare serum thiamine levels in CM patients and healthy controls. A total of 100 adults with CM and 100 healthy controls participated. The participants were matched for age and sex. Researchers measured fasting serum thiamine levels using a specific assay. Results showed that mean serum thiamine levels were significantly lower in CM patients. Thiamine levels below 30 nmol/L were strongly associated with CM. Each 10 nmol/L decrease in thiamine increased the odds of CM. Patients with low thiamine had longer disease duration and more headache days. They also reported higher frequencies of fatigue, dizziness, disturbed sleep, and abdominal pain. These findings suggest a significant link between thiamine status and the burden of CM. Further research is needed to understand the relationship between thiamine deficiency and migraine. Clinical relevance: This study indicates that monitoring thiamine levels in migraine patients may improve treatment strategies.
Key Learning Points
- Thiamine deficiency is linked to chronic migraine, indicating that low thiamine levels may contribute to the condition's severity.
- Patients with chronic migraine often have significantly lower thiamine levels compared to healthy individuals.
- Lower thiamine levels are associated with longer migraine duration and increased headache frequency.
- Symptoms like fatigue, dizziness, and disturbed sleep may be more common in patients with low thiamine levels.
- Monitoring thiamine levels could enhance treatment strategies for individuals suffering from chronic migraine.
