The white matter hyperintensities (WMH) in patients with sporadic hemiplegic migraine (SHM) is significantly more in the parietal lobe when compared with those with migraine headaches, a new study found. Fifty patients met the criteria for SHM and 100 patients met the criteria for migraine headaches. Patients in the study group were similar to the control groups in terms of age and gender. Researchers found:
- WMH were found in 28 (56%) patients with SHM and 44 (44%) in patients with migraine headache.
- The proportion of patients with WMH was not different between the groups.
- WMH burden was higher in patients with SHM, and larger white matter lesions occurred more frequently in these patients compared to ordinary migraineurs.
