In a transnsgenic mouse model for familial hemiplegic migraine spreading depression (CSD) frequency and propagation speed are increased, and post-CSD neurological deficits are more severe and prolonged. In this study we induce CSD unilaterally in the mouse brain and show using a combination of gadolinium-enhanced MRI and histology that CSD induction in heterozygote mice causes severe unilateral BBB disruption in the cortex and hippocampus, which lasts >9 days. Histology confirms blood-brain barrier leakage.
