Expert Answer: Is there any relationship of asthma to migraine disease?

Asthma and migraine are what is called “comorbid”. That means that individuals with each disorder has a higher than expected chance of having the other. However, it does not mean that one causes the other.

The reason for this is that migraine is caused by or influenced by genes. Genes are inherited as neighborhoods. When we inherit features of one condition, is common to inherit genes that influence the second condition.

You may notice that a lot of people with red hair also have light-colored skin and freckles. Not everyone with red hair looks this way, but there is a higher likelihood than by chance alone that they inherit these characteristics. But red hair doesn’t cause freckles and light skin.

Comorbid migraine and asthma, like comorbid migraine and depression, are therefore commonly seen in the same individual.
