Large and disease-specific changes in circulating neurosteroid levels are associated with chronic headache disorders, a new study found. 19 female patients affected by episodic migraine, 51 female patients affected by chronic migraine, and 18 males patients affected by cluster headache were included. Sex- and age-matched healthy control subjects were also recruited. Researchers found:
- Disease-specific changes in neurosteroid levels were observed in the study groups.
- Allopreganolone levels were significantly increased in episodic migraine and chronic migraine patients compared with control subjects, whereas they were reduced in patients affected by cluster headache.
- Dehydroepiandrosterone and dehydroepiandrosterone sulfate levels were reduced in patients affected by chronic migraine, but did not change in those affected by cluster headache.
