Brain Tissue Volume Shrinkage in Older Group With Migraine And Depression (1)

Current studies conducted at the National Institute on Aging and the Uniformed Services University of the Health Sciences, in Bethesda, Md show that older population who suffer from migraines and depression have smaller brain size in terms of brain volume compared to those in the same age group who have either one or neither of these conditions.

The study which was published in Neurology® examined 4296 persons around the approximate age of 51 years of age, over a 24 year period. This population was reassessed for another four years after a gap of 11 years by which time their average age was 74 years old.

On assessment it was found that for the migraineurs and the depressed there was an average 19.2 millilitres smaller in terms of total brain tissue volume when compared to those who had only one of these conditions or none of them.

As per the lead author of the study, Larus S. Gudmundsson, PhD, “It is important to note that participants in this study were imaged using MRI once, so we cannot say that migraine and depression resulted in brain atrophy. In future studies, we need to examine at what age participants develop both migraine and depression and measure their brain volume changes over time in order to determine what comes first.”
