In a study Professor Dale Nyholt and QUT Ph.D. researcher Rafiqul Islam, describe using large-scale genome-wide associations studies (GWAS) summary statistics to analyze hundreds of thousands of human genomes from headache and migraine sufferers and non-sufferers.
Professor Nyholt said the co-occurrence of migraine and glycemic (blood sugar levels) traits had been reported in observational epidemiological studies but it was unknown how they were genetically linked.
"About 15% of the global population is affected by migraine, and as far back as 1935, migraine was described as a 'glycemic headache,'" Professor Nyholt said.
"Glycemic traits such as insulin resistance, hyperinsulinemia (too much insulin), hypoglycemia (low blood sugar level) and type 2 diabetes are associated with migraine and headache.
"By identifying genetic correlations and shared loci and genes in our analyses we have inferred causal association and thus confirmed and improved understanding of the relationship between migraine, headache and glycemic traits."
Mr. Islam said the researchers performed cross-trait analyses to estimate genetic correlation, identify shared genomic regions, loci, genes, and pathways, and then tested for causal relationships.
"Out of the nine glycemic traits we looked at, we found a significant genetic correlation for fasting insulin (blood insulin level) and glycated hemoglobin with both migraine and headache, while two-hour glucose was genetically correlated only with migraine," he said.
"We also found regions harboring genetic risk factors shared between migraine and fasting insulin, fasting glucose, and glycated hemoglobin, and for headache, shared regions with glucose, fasting insulin, glycated hemoglobin, and fasting proinsulin.
"Further analyses produced evidence for a causal relationship between migraine and headache with multiple glycemic traits.
"Our findings provide avenues to develop novel treatment strategies for managing glycemic traits in migraine and headache patients, particularly increasing fasting proinsulin level to protect against headache."

Her family could never figure out how they disappeared after two decades. Now, with this, she may understand how.
“Glycemic headache,” indeed!
I’m a type 1 diabetic. I can’t avoid insulin, and I can’t just “eat less carbs”. I also get terrible migraines.
“Mr. Islam said...”
Always blows my mind how some of the best doctors and scientists have names like that and yet...
During the “W” administration, the USA had one in charge of all Government medicine.
During one two-day July weekend, I spent hours in the ER. (Both days).
Worse migraine pain than my several bouts with kidney stone attacks!
Finally cured with a drug “cocktail” injection. Only a few minor migraine bouts since then.
Tylenol recommended, and it’s been working.
