Altered gut microbiota in individuals with episodic and chronic migraine - Scientific Reports

Emerging evidence reveals a close association between gut microbiota and human neurological disorders. The present study aimed to assess whether the composition of gut microbiota in participants with episodic migraine (EM) and chronic migraine (CM) was altered in comparison to that of the controls. This study was a cross-sectional, case–control study. The gut microbiota were evaluated by the partial, targeted sequencing of the 16S rRNA V3–V4 region. This study enrolled 42 and 45 participants with EM and CM, respectively, and 43 controls. Alpha and beta diversities revealed no significant difference among the three groups; however, the microbiota composition at the class, order, family, and genus levels differed significantly between EM and the control, CM and the control, and the EM and CM groups. Moreover, higher composition of PAC000195_g was significantly associated with a lower headache frequency among the five genera that exhibited significantly different microbiota composition in EM and CM. Agathobacter revealed a significant negative association with severe headache intensity. The findings of the present study provide evidence of altered gut microbiota in EM and CM. These findings will help in understanding the course and treatment of migraine.

Revolutionary MRI Technology Uncovers Stunning Brain Changes in Migraine Sufferers

For the first time, a new study has identified enlarged perivascular spaces in the brains of migraine sufferers. Results of the study were presented recently at the annual meeting of the Radiological Society of North America (RSNA). “In people with chronic migraine and episodic migraine without a
