Hi Mary Mac,
A medical professional is the right person to help you with this. We can provide you with information on Migraine with Aura and Familiar Hemiplegic Migraine, but aren't aware of any connections between these types of Migraines and Aspergillus, a form of mold.
Migraine with aura information can be found HERE, and Familiar Hemiplegic Migraine information HERE.
Good luck
Nancy
