Takeaway
Diffusion tensor imaging (DTI) reveals microstructural abnormalities within the left trigeminal nerve of migraineurs compared with controls.
Why this matters
A previous histological study demonstrated microstructural abnormalities in the trigeminal nerves of migraineurs, but trigeminal nerve anatomy has not been assessed via imaging.
These results indicate that the trigeminal nerve might be a promising future target for treatment of migraine pain.
