Individuals with one disorder are at least twice as likely to have the other.1,4–7 Comorbid disease presents challenges in both differential diagnosis and concomitant diagnosis.8 When diseases are comorbid, the principle of diagnostic parsimony does not apply. Individuals with one disorder are more likely, not less likely, to have the other.
This is intersting, I had no idea they were comorbid. It makes sense since what occurs with a migraine, the excitation fo neurons, is similar but less severe than what occures during a seizure. Always interesting to know what is going on in your brain. I looked up because of the muscle jerks, sometimes quite violent, which I attribute to either FMS or migraines, but wish they were not there.
The third study suggests that even though migraine and epilepsy are clearly different syndromes, they both cause paroxystic neurological phenomena. The frequency of epilepsy in patients with migraine and migraine in those with epilepsy seems to be higher than expected. They both cause paroxystic neurological phenomena. The authors suggest there may be comorbidity in both conditions. ” This coexistence may be due to the episode of one, for example the aura of a migrainous attack, triggering off the other condition, that is an epileptic crisis. So, it may be that the ‘migrainous illness’ causes the ‘epileptic illness’ or the other way around. Their coexistence may be due to a risk factor which is common to both, since it has caused a cerebral lesion which is the cause of both disorders. Finally, a risk factor may have a direct effect, without requiring the intervention of an intermediate cerebral lesion to cause both migraine and epilepsy. This last possibility is particularly attractive to explain the comorbidity of migraine with an aura and genetically determined epilepsy”. (3)
Migraine epilepsy is very rare, but you can see how it can happen. Which means we might want to pay attention to some of those peculiar aura symptoms and how we are when we get them and violent muscle contractions.
