A new type of therapy that uses sound waves to “Balance” people’s brain activity might help lower blood pressure and reduce symptoms of migraines, early research suggests.
In another study, 52 adults with migraines underwent about 16 HIRREM sessions over nine days.
Because the findings are preliminary and the studies are small, more research is needed to confirm the results, and to determine the ways in which the therapy could be working, the researchers said.
Dr. Kevin Weber, a neurologist and headache specialist at The Ohio State University Wexner Medical Center, who was not involved in the studies, pointed out that neither of these studies included a control group, or a group that received a placebo or “Dummy” treatment.
This could have been because the study was too small to detect a meaningful difference between the groups, the researchers said.
Migraines are thought to be caused by abnormalities in the electrical activity of the brain, so it’s possible that a treatment like HIRREM, which alters the brain’s electrical activity, could affect migraines, Weber said.
The brain and nervous system also play a role in the regulation of blood pressure, so it’s possible that HIRREM could have an effect on blood pressure as well, he said.
